        create a static variable, __upc_init_func_addr, which
        is initialized to the address of the UPC
        shared data initialization function.  This change is

        Per the UPC 1.3 specification, the type of the
        optional barrier/notify/wait expression is not constrained to
        'int'. Instead, any type that is assignment compatible
        with an 'int' type is permitted.
        * c/c-parser.c (c_parser_upc_sync_statement): Do not check

        error_at() in lieu of error() when the source location is known.
        * upc/upc-act.c (upc_build_sync_stmt): Call c_cvt_expr_for_assign()

        Revert revision 178346 (2011-08-30)
        which changed the prototype of check_qualified_type and related
        functions so that their parameters were just 'tree' and not
        'const_tree'.  This seemed necessary at the time because of a
        change to TYPE_BLOCK_FACTOR(), which in turn called function
        that hashed the type node pointer.  The hash functions did
        not accept "const void *" pointers.  Implement a work around
        that removes this restriction.
        * c/c-typeck.c: Revert.
        * tree.c: Revert.
        * tree.h: Revert.  Change prototype of upc_block_factor_lookup()
        to accept a 'const_tree' pointer to a type node.
        * c-family/stub-upc.c (upc_block_factor_lookup): Update prototype.
        * upc/upc-act.c (upc_block_factor_lookup): Accept const_tree
        input argument and convert this to 'tree' for use with hash function.

        * upc/upc-pts-struct.c (upc_pts_struct_build_cond_expr):
        Use (vaddr, thread) comparison only if the UPC pointer-to-shared

2011-07-06  Gary Funck  <gary@intrepid.com>

        Re-implement the pass that lowers trees generated by
        the UPC front-end into GENERIC.  Previously this was
        done within the gimplification framework, but this
        required that gimplification be run before inlining
        and various other passes, which did not fit in well
        with the current design of the middle-end passes.
        Now, the lowering is done by a newly defined language
        specific genericize hook.  With this change, we are
        are able to undo some extensions made to the gimplify
        logic, and thus can revert several files to trunk.
        * c-decl.c: Add a check for UPC deprecated names which
          may appear as undefined function names.
        * libfuncs.h (LTI_upc_barrier, LTI_upc_notify, LTI_upc_wait,
          LTI_upc_getaddr): Remove definitions of unused UPC
          library function names.  These were defined back when
          the libfunc interface was used to call these routines.
        * timevar.def (TV_TREE_UPC_GENERICIZE): New. Track time spent
          in UPC lowering (genericize) pass.
        * langhooks.h (gimplify_expr): Revert to trunk's definition.
          (instrument_func): Delete this hook.  Now handled in
          upc_genericize().
        * tree-pass.h: Revert to trunk.
        * c-typeck.c (build_unary_op): Adjust reference to
          upc_genericize() in a comment.
        * gimplify.c (create_tmp_var_raw): Delete logic that
          was converting UPC shared types into unshared types
          to be used for temporaries.  Now handled in  upc_genericize().
          Replace with an assertion check.
          (prepare_gimple_addressable): Revert to trunk's definition.
          No longer needed as an externally called function.
          (flag_instrument_functions_exclude_p): Re-define as
          an externally called function.
          (gimplify_function_tree): Delete code that implemented
          call to UPC's language specific function instrumentation hook.
        * gimple.h (flag_instrument_functions_exclude_p): Define as extern.
          (prepare_gimple_addressable): Delete extern definition;

        libcpp/
        * include/cpplib.h (enum c_lang):
        Move the entry for CLK_UPC so that it follows CLK_STDC1X.
        This keeps all the "C" variants together.

2011-06-09  Gary Funck  <gary@intrepid.com>

        * c-parser.c (upc_localsizeof_type): Fix an ICE when compiling for
        a 32-bit target, the size expression overflowed, the result was
        error_mark_node, and an ICE was triggered on an attempt to evaluate
        C_TYPE_VARIABLE_SIZE() on the error node.
        (upc_blocksizeof_expr, upc_blocksizeof_type,
        upc_elemsizeof_expr, upc_elemsizeof_type, upc_localsizeof_expr):
        Make similar changes to avoid further processing of error_mark_node.

        * configure.ac: Make the default order of the virtual
          address field in a UPC pointer-to-shared to be "first".
          This reverts to the previous setting, and is a short term
          measure to work around a bug found on the IA64,
          where vaddr=last led to incorrect code generation.
          Rename UPC_PTS_VADDR_FIRST to HAVE_UPC_PTS_VADDR_FIRST
          in AC_DEFINE(), to agree with recent changes in files
          that reference this define.

          types and objects.
        * c-parser.c (c_parser_upc_forall_statement): Remove

        * config/upc-conf.h (UPC_MAX_THREADS): Define as an
          integer constant, not a string.  Range is restricted
          to maximum positive 32-bit integer (2+ billion) to
          fit in with the use of 'int' in the front-end's
          switch handling logic.

2011-03-20  Gary Funck  <gary@intrepid.com>

        Move UPC start files, end files, and linker specs.
        into libupc.  This reduces the impact on common GCC
        configuration files, and ensures that these UPC-specific
        components are only built when the UPC language dialect is selected.

          affinity (previously used by the 'upc' driver); these
          settings are now propagated by target-specific compiler
          specs. built by libupc.  Regenerate autoconf.
        * gcc.c (LINK_COMMAND_SPEC): Add call outs to UPC-related
          linker compiler specifications, accessed via %:include().
          Define 'upc_crtbegin_spec', 'upc_crtend_spec', and

        * c-typeck.c: Fix bug: Cast of (shared <type> * shared) not
          diagnosed as an error
          The conversion from any type (shared or not) to
          a shared type is likely either meaningless or an error.  This update
          makes any conversion to a shared type, an error.

        * c-typeck.c: Fix bug: passing int to shared pointer arg.

          Add a #define procedure that does the same thing as
          WARN_FOR_ASSIGNMENT but issues an error diagnostic instead.  Use
          this procedure to diagnose passing an integer value to a
          pointer-to-shared as an error.

2010-10-18  Gary Funck  <gary@intrepid.com>

        * c-typeck.c: Fix bug: shared [] in prototype silently ignored when
          matching routine declaration.
          When checking for type compatibility, shared qualified types must
          have the same block factor.  This check was missing from
          comptypes_internal().  This update adds the check for blocking
          factor equality.

        * c-decl.c: Fix a segfault/ICE that occurred when printing an error
          message regarding a function parameter being declared with a shared
          qualifier.
          The parameter's 'name' value is not defined at this point, and
          cannot be used in the error message.  This update removes the
          reference to 'name', and eliminates the segfault.

2010-10-16  Gary Funck  <gary@intrepid.com>

        * Makefile.in: Implement fixes for SGI/IRIX/MIPS port.
          The gcc/Makefile.in rules for install-plugin had to be re-written to
          break up a long list of header files that exceeded the command line
          limitation imposed by Irix.
          Access functions for TFmode types had to be implemented.
          Apparently, this is the mode used for the SGI/MIPS port to represent
          "long float".

2010-10-14  Gary Funck  <gary@intrepid.com>

        * c-decl.c: Fix bug: Multiple equal blocking factors specified
          via typedef chain should not be diagnosed as an error.
          If the block size that is given by the typedef is equal to the block
          size given explicitly in the variable declaration, then do not
          complain.  The easiest way to make this check was to create a
          temporary type that is a clone of the element type and then set its
          block size using the given layout qualifier.  Then compare the block
          size of the temporary (the declaration) to the block size specified
          in the typedef.  This complexity is needed, because the '[*]' block
          size needs to be calculated, and the '[]' needs to be mapped into a
          zero block size.

2010-10-10  Gary Funck  <gary@intrepid.com>

        * c-decl.c: Fix bug: ICE: two or more layout qualifiers
          specified
          The compiler properly detected the presence of two or more layout
          qualifiers as an error, but then hit an assertion check, because the
          code that followed the error expected to see a qualifier and not a
          layout specifier.  The fix is simple: just return immediately after
          detecting the error.

2010-10-10  Gary Funck  <gary@intrepid.com>

        * c-decl.c: Improve error diagnostics for various cases of UPC
          shared array type declarations.
          Add the check for this error: "In the dynamic translation
          environment, THREADS may not appear in declarations of shared arrays
          with indefinite block size".  Also, fix up a few of the other
          related error diagnostics.

2010-10-09  Gary Funck  <gary@intrepid.com>

        * c-common.c: Fix bug: segfault on incomplete array definition.
          This turned out to be a bit complicated.   The logic in
          upc_lang_layout_decl had to be re-arranged to avoid trying to lookup
          the THREADS identifier in the case where the blocking factor has
          been set to indefinite ([]).  This can happen when indefinite array
          declarations are processed for shared arrays.  At that time, the
          file scope has been closed and THREADS is no longer in scope.  Some
          more work is needed on upc_lang_layout_decl().  It has some
          duplication, and notably duplicates the two branches of the if
          having to do with TYPE_SIZE and TYPE_SIZE_UNIT, that appear in the
          caller of this routine (layout_decl()).
          The method of forcing a layout qualifier of [] in the indefinite
          declaration handler is odd a well.  The code that just does the
          setting of the block factor, needs to moved into its own routine
          that doesn't depend upon a declspec for '[]' to be passed in, just
          in order to set the blocking factor to some value (in this case, 0).
          Also, the logic for how that shared type is constructed is strange.
          First the type with 0 blocking factor is set.  Then the shared
          qualifier is removed from the type, and then added back later.  The
          intermediate type has a blocking factor set, but it has no shared
          qualifier.  Fixing this will require some thought.  It is tempting
          just to make indefinite shared arrays an error, rather than forcing
          the dimension to be '1'.
          This likely fixes a serious error in the previous update to
          upc_lang_layout_decl(), where it didn't have the logic to set
          TYPE_SIZE_UNIT() in the main part of the 'if' statement.  This means
          the previous update would fail on many tests.

2010-10-09  Gary Funck  <gary@intrepid.com>

        * varasm.c: Add an assertion check for the case that DECL_SIZE_UNIT
          (decl) is null, which can happen if some layout error occurred
          upstream.

2010-10-09  Gary Funck  <gary@intrepid.com>

        * c-decl.c: Fix bug: file scope shared arrays mis-diagnosed as
          "variable-sized" when compiled in dynamic threads.
          This long-standing bug is easily fixed.  Just check
          for the situation that the non-constant sized type is shared and
          that it does not have a dimension that references a multiple of
          threads.  If this criteria is met, then issue a meaningful
          diagnostic.

2010-10-01  Gary Funck  <gary@intrepid.com>

        * configure, configure.ac: Update manual page, and bug reporting
          URL.  Update "man" page to reflect debugging switches.
          Also, some general clean up.  Change the bug reporting
          URL to point to gccupc.org.

2010-09-27  Gary Funck  <gary@intrepid.com>

        * c-parser.c, config/upc-conf.h: Issue a descriptive message when
          the UPC forall depth count variable is not found.
          The __upc_forall_depth variable should be defined in gcc-upc-lib.h.
          The compiler will generate code that references this variable in
          order to implement nested upc_forall semantics.  If there is a
          compiler build or install problem, this variable may not be found.
          In this case, terminate with an internal_error().

          bug873a.upc, which has the code:
               double d;
               upc_forall (;;;d) {...} The compiler did not properly handle
          the empty "condition" clause, and did not recover well when it was
          determined that the use of a double value, "d" above, was neither a
          pointer-to-shared nor an integer expression.  The update implements a
          fix for both issues.

        * c-decl.c: Fix Bug 29: Layout qualifier within a typedef is not
          incorporated into the referencing type.
          This was semi-fixed a few times before.  This update fixes a few
          more places where the layout qualifier wasn't being propagated
          through typedef's properly.  What made this a bit tricky is shown in
          the example cited in the bug report:
          typedef shared [5] int A_t; A_t A[5*THREADS];
          In the typedef, the blocksize is being applied to a shared *scalar*,
          and the code was applying the blocksize only to arrays.  This update
          handles shared scalars correctly.

        * c-parser.c, c-tree.h, stub-upc.c: Fix Bug 403: Nested
          upc_forall() semantics are not implemented
          The checkforall test in the Berkeley harness test suite indicated
          that GCC/UPC was not properly implementing nested upc_forall
          semantics.  Nested upc_forall statements (both statically or
          dynamically nested) must implement their affinity clause as if it
          were "continue"; thus all steps in the loop must execute without
          regard for affinity.  To implement these semantics a global depth
          counter, __upc_forall_depth, is maintained by the generated code
          that implements upc_forall.

        * c-decl.c: c-decl.c: zero out the layout specifier, after
          processing an array type.
          Fix the previous fix, that moved the setting of the type's layout
          qualifier to the outside of the array type processing loop.  What is
          missing from the fix is that the layout_qualifier variable needs to
          be cleared after setting the type's blocksize.

        * config/upc-conf.h: Fix Bug 375: error message is off-by-one when
          given blocksize is greater than UPC_MAX_BLOCKSIZE.
          The value we were using for UPC_MAX_BLOCK_SIZE was one bigger than
          the actual maximum block size.  Therefore, the message was correct,
          but the underlying value that was being checked was wrong.  Change
          the values so that they agree with the actual implementation-defined
          limit.

2010-09-11  Gary Funck  <gary@intrepid.com>

        * c-decl.c: Fix Bug 402: ICE: '[*]' layout factor on
          multi-dimensional shared array with dynamic threads.
          This declaration caused an internal compiler error when compiled
          with dynamic threads:
              shared [*] int A[THREADS][16]; The bug was discovered when
          compiling the RTED_UPC test suite.
          The fix is to process layout qualifiers after the entire array type
          has been built.  Otherwise, we try to calculate the blocksize on a
          shared array type that has not had its "size depends upon the value
          of THREADS" flag set.
          Also, added a test case.

        Fix a bug where a statement in c_build_qualified_type()
        in the trunk had been inadvertently deleted.
        This bug showed up in the IA64 port, because jmpbuf's

2010-07-08  Gary Funck  <gary@intrepid.com>

        Make changes so that other language compilers

        upc-lang.c.
        * c-family/c-common.h (use_upc_dwarf2_extensions,
        compiling_upc): Add extern definitions - needed

        flag_upc_instrument, flag_upc_instrument_functions):
        Remove these definitions.  They have been moved

        * upc/ChangeLog: Move relevant entries
        to ChangeLog.upc.
        * c-family/stub-upc.c (compiling_upc, flag_upc,

        * objc/objc-act.c (objc_gimplify_expr): Add additional

        * libcpp/include/cpplib.h: Remove CL_UPC from
        the list of language kinds accepted by the

        UPC is a derivative of C99, and does not need
        a different language kind.
        * c-fmaily/c-opts.c (c_common_handle_option):
        Call set_std_c99() when processing the

        language kind to CL_UPC.

2011-07-06  Gary Funck  <gary@intrepid.com>

        Re-implement the pass that lowers trees generated by
        the UPC front-end into GENERIC.  Previously this was
        done within the gimplification framework, but this
        required that gimplification be run before inlining
        and various other passes, which did not fit in well
        with the current design of the middle-end passes.
        Now, the lowering is done by a newly defined language
        specific genericize hook.  With this change, we are
        are able to undo some extensions made to the gimplify
        logic, and thus can revert several files to trunk.
        * c-decl.c: Add a check for UPC deprecated names which
          may appear as undefined function names.
        * libfuncs.h (LTI_upc_barrier, LTI_upc_notify, LTI_upc_wait,
          LTI_upc_getaddr): Remove definitions of unused UPC
          library function names.  These were defined back when
          the libfunc interface was used to call these routines.
        * timevar.def (TV_TREE_UPC_GENERICIZE): New. Track time spent
          in UPC lowering (genericize) pass.
        * langhooks.h (gimplify_expr): Revert to trunk's definition.
          (instrument_func): Delete this hook.  Now handled in

          upc_genericize() in a comment.
        * gimplify.c (create_tmp_var_raw): Delete logic that
          was converting UPC shared types into unshared types
          to be used for temporaries.  Now handled in  upc_genericize().
          Replace with an assertion check.
          (prepare_gimple_addressable): Revert to trunk's definition.
          No longer needed as an externally called function.

2011-06-13  Gary Funck  <gary@intrepid.com>

        libcpp/
        * include/cpplib.h (enum c_lang):
        Move the entry for CLK_UPC so that it follows CLK_STDC1X.
        This keeps all the "C" variants together.
        * init.c (lang_defaults): Add an entry for UPC.

2011-06-10  Gary Funck  <gary@intrepid.com>

        * upc/upc-act.c (upc_set_block_factor): Handle the case where
        the UPC blocking factor expression overflowed.

2011-06-09  Gary Funck  <gary@intrepid.com>

        * c-parser.c (upc_localsizeof_type): Fix an ICE when compiling for
        a 32-bit target, the size expression overflowed, the result was
        error_mark_node, and an ICE was triggered on an attempt to evaluate
        C_TYPE_VARIABLE_SIZE() on the error node.

        patch to eliminate ICE at -O3 on IA64/Altix.

2011-06-07  Alexander Monakov  <amonakov@ispras.ru>

        * sel-sched.c (move_op): Use correct type for 'res'.  Verify that

        Merge trunk version 174558 into gupc branch.
        * upc/upc-lang.c (upc_check_decl_init): Use recently defined
        'append_to_statement_list_force' function to add UPC
        initialization statements to the UPC initialization
        statement list ('upc_init_stmt_list').
        (upc_build_init_func): Use recently defined
        'append_to_statement_list_force' function to add
        statements listed in 'upc_init_stmt_list' onto the
        function body constructed to implement initialization
        of UPC declarations that require active initialization
        at program start up.  The previous methods of manipulating
        statement lists no longer worked, due to changes in the
        the statement list structure.

2011-05-30  Gary Funck  <gary@intrepid.com>

        * configure.ac: Make the default order of the virtual
          address field in a UPC pointer-to-shared to be "first".
          This reverts to the previous setting, and is a short term
          measure to work around a bug found on the IA64,
          where vaddr=last led to incorrect code generation.
          Rename UPC_PTS_VADDR_FIRST to HAVE_UPC_PTS_VADDR_FIRST
          in AC_DEFINE(), to agree with recent changes in files
          that reference this define.

2011-05-23  Gary Funck  <gary@intrepid.com>

        * upc/upc-pts-struct.c: Revert to code that aligned the
          internal pointer-to-shared representation to
          twice the alignment of a pointer.  This fixes
          an ICE that occurred when building the compiler
          on an IA64 target.

          types and objects.
        * c-parser.c (c_parser_upc_forall_statement): Remove

          to refer to the handlers for the UPC pointer-to-shared
          representation (packed/struct) that has been configured.
          Add conditional compilation test for HAVE_UPC_PTS_PACKED_REP
          and configure the UPC pointer-to-shared definitions that

          rewrite UPC shared REALPART_EXPR and IMAGPART_EXPR lvalues.
          This will avoid an ICE when compiling regular "C"
          code that refers to those operators.

          (like SGI/Irix), they will be defined by the custom
          linker spec. built in libupc.  Remove test for
          HAVE_UPC_NUMA_SUPPORT; if '-lnuma' is needed, it

        * upc/upc-pts-struct.c: Fix bug: (pts + int) fails when int is negative
          for struct-pts representation
          Analysis indicated that for something like (+ ptr -80) this was
          being represented as (+ ptr (- 80)) and further, when the
          calculations were propagated into the individual operations on the
          components of the 'struct' pointer, it would end up with something
          like (+ ptr.vaddr (- 80)), and the type of (- 80) would end up as
          "long unsigned int" because of the addition to the pointer.  This
          caused the calculations involving the signed 'int' operand to be
          performed incorrectly.  This fix insures that the 'int' operand is
          signed.

        (upc_write_global_declarations) New, replaces upc_finish_file.
        * lang-spec.h: Disable multi-file compilation for .upc files.
        This fixes an issue where file-scoped static variables were
        diagnosed as multiply-defined.  Both "C" and "ObjC" also disable

          The conversion from any type (shared or not) to
          a shared type is likely either meaningless or an error.  This update
          makes any conversion to a shared type, an error.

        * c-decl.c: Fix a segfault/ICE that occurred when printing an error
          message regarding a function parameter being declared with a shared
          qualifier.
          The parameter's 'name' value is not defined at this point, and
          cannot be used in the error message.  This update removes the
          reference to 'name', and eliminates the segfault.

        * upc/upc-act.c: Issue a compilation error on attempts to perform
          arithmetic on generic pointer-to-shared values.
          (The rest of this update is a small code clean up.)

2010-10-17  Gary Funck  <gary@intrepid.com>

        * upc/upc-lang.c: For UPC only, issue errors for arithmetic and related
          operations on void types.
          This update simulates the effect of -Werror=pointer-arith, thus
          causing arithmetic on void types, sizeof(void) and so on to be
          considered compilation errors.  This meets the expectations of some
          harness tests and the RTED/CTED test suites.  GCC is more
          permissive, but since this is for UPC only, we can fairly safely
          define this new policy.

2010-10-16  Gary Funck  <gary@intrepid.com>

        * Makefile.in: Implement fixes for SGI/IRIX/MIPS port.
          The gcc/Makefile.in rules for install-plugin had to be re-written to
          break up a long list of header files that exceeded the command line
          limitation imposed by Irix.
          Access functions for TFmode types had to be implemented.
          Apparently, this is the mode used for the SGI/MIPS port to represent
          "long float".

2010-10-16  Gary Funck  <gary@intrepid.com>

        * upc/upc-act.c: Fix bug: Static initialization of shared
          arrays is unsupported -- issue an error message.
          Currently, static initialization of a shared array is not
          implemented correctly.
          We do not plan to fix this for a while, therefore the compiler will
          issue an error message indicating that this is an unsupported
          operation.

2010-10-14  Gary Funck  <gary@intrepid.com>

        * c-decl.c: Fix bug: Multiple equal blocking factors specified
          via typedef chain should not be diagnosed as an error.
          If the block size that is given by the typedef is equal to the block
          size given explicitly in the variable declaration, then do not
          complain.  The easiest way to make this check was to create a
          temporary type that is a clone of the element type and then set its
          block size using the given layout qualifier.  Then compare the block
          size of the temporary (the declaration) to the block size specified
          in the typedef.  This complexity is needed, because the '[*]' block
          size needs to be calculated, and the '[]' needs to be mapped into a
          zero block size.

2010-10-13  Gary Funck  <gary@intrepid.com>

        * upc/upc-act.c: Fix bug: negative layout qualifiers not diagnosed
          as an error.
          The CTED_UPC test c_A_1_3_b.upc, specified a negative blocksize, but
          it was not diagnosed as an error.  With this fix, negative block
          sizes will generate a translation error.

2010-10-10  Gary Funck  <gary@intrepid.com>

        * c-decl.c: Fix bug: ICE: two or more layout qualifiers
          specified
          The compiler properly detected the presence of two or more layout
          qualifiers as an error, but then hit an assertion check, because the
          code that followed the error expected to see a qualifier and not a
          layout specifier.  The fix is simple: just return immediately after
          detecting the error.

2010-10-10  Gary Funck  <gary@intrepid.com>

        * c-decl.c: Improve error diagnostics for various cases of UPC
          shared array type declarations.
          Add the check for this error: "In the dynamic translation
          environment, THREADS may not appear in declarations of shared arrays
          with indefinite block size".  Also, fix up a few of the other
          related error diagnostics.

2010-10-10  Gary Funck  <gary@intrepid.com>

        * upc/upc-act.c: Fix bug: ICE: Attempt to take the difference of
          shared and non-shared pointers
          The compiler detected the error, and then tried to return
          error_mark_node.  This apparently is not acceptable, as there is an
          explicit assertion check to prevent this from happening in
          build_binary_op.  Return the more user-friendly size_one_node
          instead.

2010-10-09  Gary Funck  <gary@intrepid.com>

        * c-common.c: Fix bug: segfault on incomplete array definition.
          This turned out to be a bit complicated.   The logic in
          upc_lang_layout_decl had to be re-arranged to avoid trying to lookup
          the THREADS identifier in the case where the blocking factor has
          been set to indefinite ([]).  This can happen when indefinite array
          declarations are processed for shared arrays.  At that time, the
          file scope has been closed and THREADS is no longer in scope.  Some
          more work is needed on upc_lang_layout_decl().  It has some
          duplication, and notably duplicates the two branches of the if
          having to do with TYPE_SIZE and TYPE_SIZE_UNIT, that appear in the
          caller of this routine (layout_decl()).
          The method of forcing a layout qualifier of [] in the indefinite
          declaration handler is odd a well.  The code that just does the
          setting of the block factor, needs to moved into its own routine
          that doesn't depend upon a declspec for '[]' to be passed in, just
          in order to set the blocking factor to some value (in this case, 0).
          Also, the logic for how that shared type is constructed is strange.
          First the type with 0 blocking factor is set.  Then the shared
          qualifier is removed from the type, and then added back later.  The
          intermediate type has a blocking factor set, but it has no shared
          qualifier.  Fixing this will require some thought.  It is tempting
          just to make indefinite shared arrays an error, rather than forcing
          the dimension to be '1'.
          This likely fixes a serious error in the previous update to
          upc_lang_layout_decl(), where it didn't have the logic to set
          TYPE_SIZE_UNIT() in the main part of the 'if' statement.  This means
          the previous update would fail on many tests.

        * varasm.c: Add an assertion check for the case that DECL_SIZE_UNIT
          (decl) is null, which can happen if some layout error occurred
          upstream.

        * c-decl.c: Fix bug: file scope shared arrays mis-diagnosed as
          "variable-sized" when compiled in dynamic threads.
          This long-standing bug is easily fixed.  Just check
          for the situation that the non-constant sized type is shared and
          that it does not have a dimension that references a multiple of
          threads.  If this criteria is met, then issue a meaningful
          diagnostic.

        * upc/upc-act.c: Fix bug: segfault on incomplete array definition.
          This turned out to be a bit complicated.   The logic in
          upc_lang_layout_decl had to be re-arranged to avoid trying to lookup
          the THREADS identifier in the case where the blocking factor has
          been set to indefinite ([]).  This can happen when indefinite array
          declarations are processed for shared arrays.  At that time, the
          file scope has been closed and THREADS is no longer in scope.  Some
          more work is needed on upc_lang_layout_decl().  It has some
          duplication, and notably duplicates the two branches of the if
          having to do with TYPE_SIZE and TYPE_SIZE_UNIT, that appear in the
          caller of this routine (layout_decl()).
          The method of forcing a layout qualifier of [] in the indefinite

        * upc/upc-act.c: Do not zap all qualifier bits when constructing a
          non-shared result node.
          This fix was suggested by Paul H. in the following Berkeley Bugzilla
          report: https://upc-bugs.lbl.gov/bugzilla/show_bug.cgi?id=2061 The
          use of "!" rather than "~" zapped all the type qualifier bits rather
          than just those that are related to the "shared" qualifier.  This
          fix clears only the relevant bits.

          The __upc_forall_depth variable should be defined in gcc-upc-lib.h.
          The compiler will generate code that references this variable in
          order to implement nested upc_forall semantics.  If there is a
          compiler build or install problem, this variable may not be found.
          In this case, terminate with an internal_error().

        * c-decl.c: Fix Bug 29: Layout qualifier within a typedef is not
          incorporated into the referencing type.
          This was semi-fixed a few times before.  This update fixes a few
          more places where the layout qualifier wasn't being propagated
          through typedef's properly.  What made this a bit tricky is shown in
          the example cited in the bug report:
          typedef shared [5] int A_t; A_t A[5*THREADS];
          In the typedef, the blocksize is being applied to a shared *scalar*,
          and the code was applying the blocksize only to arrays.  This update
          handles shared scalars correctly.

          upc_forall() semantics are not implemented
          The checkforall test in the Berkeley harness test suite indicated
          that GCC/UPC was not properly implementing nested upc_forall
          semantics.  Nested upc_forall statements (both statically or
          dynamically nested) must implement their affinity clause as if it
          were "continue"; thus all steps in the loop must execute without
          regard for affinity.  To implement these semantics a global depth
          counter, __upc_forall_depth, is maintained by the generated code
          that implements upc_forall.

        * c-decl.c: c-decl.c: zero out the layout specifier, after
          processing an array type.
          Fix the previous fix, that moved the setting of the type's layout
          qualifier to the outside of the array type processing loop.  What is
          missing from the fix is that the layout_qualifier variable needs to
          be cleared after setting the type's blocksize.

          The value we were using for UPC_MAX_BLOCK_SIZE was one bigger than
          the actual maximum block size.  Therefore, the message was correct,
          but the underlying value that was being checked was wrong.  Change
          the values so that they agree with the actual implementation-defined
          limit.

        * c-decl.c: Fix Bug 402: ICE: '[*]' layout factor on
          multi-dimensional shared array with dynamic threads.
          This declaration caused an internal compiler error when compiled
          with dynamic threads:
              shared [*] int A[THREADS][16]; The bug was discovered when
          compiling the RTED_UPC test suite.
          The fix is to process layout qualifiers after the entire array type
          has been built.  Otherwise, we try to calculate the blocksize on a
          shared array type that has not had its "size depends upon the value
          of THREADS" flag set.
          Also, added a test case.
