+   compatibility can change DRAFT_V4_STRUCT_RET to override the
+   default, and -m switches get the final word.  See
+   rs6000_option_override_internal for more details.

+   function, used to implement C++ virtual function calls with
+   multiple inheritance.  The thunk acts as a wrapper around a virtual
+   function, adjusting the implicit object parameter before handing
+   control off to the real function.
+
+   First, emit code to add the integer DELTA to the location that
+   contains the incoming first argument.  Assume that this argument
+   contains a pointer, and is the one used to pass the `this' pointer
+   in C++.  This is the incoming argument *before* the function
+   prologue, e.g. `%o0' on a sparc.  The addition must preserve the
+   values of all other incoming arguments.
+
+   After the addition, emit code to jump to FUNCTION, which is a
+   `FUNCTION_DECL'.  This is a direct pure jump, not a call, and does
+   not touch the return address.  Hence returning from FUNCTION will
+   return to whoever called the current `thunk'.
+
+   The effect must be as if FUNCTION had been called directly with the
+   adjusted first argument.  This macro is responsible for emitting
+   all of the code for a thunk function; output_function_prologue()
+   and output_function_epilogue() are not invoked.
+
+   The THUNK_FNDECL is redundant.  (DELTA and FUNCTION have already
+   been extracted from it.)  It might possibly be useful on some
+   targets, but probably not.
+
+   If you do not define this macro, the target-independent code in the
+   C++ frontend will generate a less efficient heavyweight thunk that
+   calls FUNCTION instead of jumping to it.  The generic approach does

+     to track the current state of load/store issue.
+
+       - If the pendulum is at zero, then no loads or stores have been
+         issued in the current cycle so we do nothing.
+
+       - If the pendulum is 1, then a single load has been issued in this
+         cycle and we attempt to locate another load in the ready list to
+         issue with it.
+
+       - If the pendulum is -2, then two stores have already been
+         issued in this cycle, so we increase the priority of the first load
+         in the ready list to increase it's likelihood of being chosen first
+         in the next cycle.
+
+       - If the pendulum is -1, then a single store has been issued in this
+         cycle and we attempt to locate another store in the ready list to
+         issue with it, preferring a store to an adjacent memory location to
+         facilitate store pairing in the store queue.
+
+       - If the pendulum is 2, then two loads have already been
+         issued in this cycle, so we increase the priority of the first store
+         in the ready list to increase it's likelihood of being chosen first
+         in the next cycle.
+
+       - If the pendulum < -2 or > 2, then do nothing.
+
+       Note: This code covers the most common scenarios.  There exist non
+             load/store instructions which make use of the LSU and which

+   form in practice.  It tries to achieve this synchronization by forcing the
+   estimated processor grouping on the compiler (as opposed to the function
+   'pad_goups' which tries to force the scheduler's grouping on the processor).
+
+   The function scans the insn sequence between PREV_HEAD_INSN and TAIL and
+   examines the (estimated) dispatch groups that will be formed by the processor
+   dispatcher.  It marks these group boundaries to reflect the estimated
+   processor grouping, overriding the grouping that the scheduler had marked.
+   Depending on the value of the flag '-minsert-sched-nops' this function can
+   force certain insns into separate groups or force a certain distance between
+   them by inserting nops, for example, if there exists a "costly dependence"
+   between the insns.
+
+   The function estimates the group boundaries that the processor will form as
+   follows:  It keeps track of how many vacant issue slots are available after
+   each insn.  A subsequent insn will start a new group if one of the following
+   4 cases applies:
+   - no more vacant issue slots remain in the current dispatch group.
+   - only the last issue slot, which is the branch slot, is vacant, but the next
+     insn is not a branch.
+   - only the last 2 or less issue slots, including the branch slot, are vacant,
+     which means that a cracked insn (which occupies two issue slots) can't be
+     issued in this group.
+   - less than 'issue_rate' slots are vacant, and the next insn always needs to
+     start a new group.  */

+/* Expand an Altivec constant permutation for little endian mode.
+   There are two issues: First, the two input operands must be
+   swapped so that together they form a double-wide array in LE
+   order.  Second, the vperm instruction has surprising behavior
+   in LE mode:  it interprets the elements of the source vectors
+   in BE mode ("left to right") and interprets the elements of
+   the destination vector in LE mode ("right to left").  To
+   correct for this, we must subtract each element of the permute
+   control vector from 31.
+
+   For example, suppose we want to concatenate vr10 = {0, 1, 2, 3}
+   with vr11 = {4, 5, 6, 7} and extract {0, 2, 4, 6} using a vperm.
+   We place {0,1,2,3,8,9,10,11,16,17,18,19,24,25,26,27} in vr12 to
+   serve as the permute control vector.  Then, in BE mode,
+
+     vperm 9,10,11,12
+
+   places the desired result in vr9.  However, in LE mode the 
+   vector contents will be
+
+     vr10 = 00000003 00000002 00000001 00000000
+     vr11 = 00000007 00000006 00000005 00000004
+
+   The result of the vperm using the same permute control vector is
+
+     vr9  = 05000000 07000000 01000000 03000000
+
+   That is, the leftmost 4 bytes of vr10 are interpreted as the
+   source for the rightmost 4 bytes of vr9, and so on.
+
+   If we change the permute control vector to
+
+     vr12 = {31,20,29,28,23,22,21,20,15,14,13,12,7,6,5,4}
+
+   and issue
+
+     vperm 9,11,10,12
+
+   we get the desired
+
+   vr9  = 00000006 00000004 00000002 00000000.  */

+/* Analyze vector computations and remove unnecessary doubleword
+   swaps (xxswapdi instructions).  This pass is performed only
+   for little-endian VSX code generation.
+
+   For this specific case, loads and stores of 4x32 and 2x64 vectors
+   are inefficient.  These are implemented using the lvx2dx and
+   stvx2dx instructions, which invert the order of doublewords in
+   a vector register.  Thus the code generation inserts an xxswapdi
+   after each such load, and prior to each such store.  (For spill
+   code after register assignment, an additional xxswapdi is inserted
+   following each store in order to return a hard register to its
+   unpermuted value.)
+
+   The extra xxswapdi instructions reduce performance.  This can be
+   particularly bad for vectorized code.  The purpose of this pass
+   is to reduce the number of xxswapdi instructions required for
+   correctness.
+
+   The primary insight is that much code that operates on vectors
+   does not care about the relative order of elements in a register,
+   so long as the correct memory order is preserved.  If we have
+   a computation where all input values are provided by lvxd2x/xxswapdi
+   sequences, all outputs are stored using xxswapdi/stvxd2x sequences,
+   and all intermediate computations are pure SIMD (independent of
+   element order), then all the xxswapdi's associated with the loads
+   and stores may be removed.
+
+   This pass uses some of the infrastructure and logical ideas from
+   the "web" pass in web.c.  We create maximal webs of computations
+   fitting the description above using union-find.  Each such web is
+   then optimized by removing its unnecessary xxswapdi instructions.
+
+   The pass is placed prior to global optimization so that we can
+   perform the optimization in the safest and simplest way possible;
+   that is, by replacing each xxswapdi insn with a register copy insn.
+   Subsequent forward propagation will remove copies where possible.
+
+   There are some operations sensitive to element order for which we
+   can still allow the operation, provided we modify those operations.
+   These include CONST_VECTORs, for which we must swap the first and
+   second halves of the constant vector; and SUBREGs, for which we
+   must adjust the byte offset to account for the swapped doublewords.
+   A remaining opportunity would be non-immediate-form splats, for
+   which we should adjust the selected lane of the input.  We should
+   also make code generation adjustments for sum-across operations,
+   since this is a common vectorizer reduction.
+
+   Because we run prior to the first split, we can see loads and stores
+   here that match *vsx_le_perm_{load,store}_<mode>.  These are vanilla
+   vector loads and stores that have not yet been split into a permuting
+   load/store and a swap.  (One way this can happen is with a builtin
+   call to vec_vsx_{ld,st}.)  We can handle these as well, but rather
+   than deleting a swap, we convert the load/store into a permuting
+   load/store (which effectively removes the swap).  */
+
+/* Notes on Permutes
+
+   We do not currently handle computations that contain permutes.  There
+   is a general transformation that can be performed correctly, but it
+   may introduce more expensive code than it replaces.  To handle these
+   would require a cost model to determine when to perform the optimization.
+   This commentary records how this could be done if desired.
+
+   The most general permute is something like this (example for V16QI):
+
+   (vec_select:V16QI (vec_concat:V32QI (op1:V16QI) (op2:V16QI))
+                     (parallel [(const_int a0) (const_int a1)
+                                 ...
+                                (const_int a14) (const_int a15)]))
+
+   where a0,...,a15 are in [0,31] and select elements from op1 and op2
+   to produce in the result.
+
+   Regardless of mode, we can convert the PARALLEL to a mask of 16
+   byte-element selectors.  Let's call this M, with M[i] representing
+   the ith byte-element selector value.  Then if we swap doublewords
+   throughout the computation, we can get correct behavior by replacing
+   M with M' as follows:
+
+            { M[i+8]+8 : i < 8, M[i+8] in [0,7] U [16,23]
+    M'[i] = { M[i+8]-8 : i < 8, M[i+8] in [8,15] U [24,31]
+            { M[i-8]+8 : i >= 8, M[i-8] in [0,7] U [16,23]
+            { M[i-8]-8 : i >= 8, M[i-8] in [8,15] U [24,31]
+
+   This seems promising at first, since we are just replacing one mask
+   with another.  But certain masks are preferable to others.  If M
+   is a mask that matches a vmrghh pattern, for example, M' certainly
+   will not.  Instead of a single vmrghh, we would generate a load of
+   M' and a vperm.  So we would need to know how many xxswapd's we can
+   remove as a result of this transformation to determine if it's
+   profitable; and preferably the logic would need to be aware of all
+   the special preferable masks.
+
+   Another form of permute is an UNSPEC_VPERM, in which the mask is
+   already in a register.  In some cases, this mask may be a constant
+   that we can discover with ud-chains, in which case the above
+   transformation is ok.  However, the common usage here is for the
+   mask to be produced by an UNSPEC_LVSL, in which case the mask 
+   cannot be known at compile time.  In such a case we would have to
+   generate several instructions to compute M' as above at run time,
+   and a cost model is needed again.  */

+# This is the GCC target-specific configuration file
+# where a configuration type is mapped to different system-specific
+# definitions and files.  This is invoked by the autoconf-generated
+# configure script.  Putting it in a separate shell file lets us skip
+# running autoconf when modifying target-specific information.
+
+# When you change the cases in the OS or target switches, consider
+# updating ../libgcc/config.host also.
+
+# This file switches on the shell variable ${target}, and also uses the
+# following shell variables:
+#
+#  with_*              Various variables as set by configure.
+#
+#  enable_threads      Either the name, yes or no depending on whether
+#                      threads support was requested.
+#
+#  default_use_cxa_atexit
+#                        The default value for the $enable___cxa_atexit
+#                      variable.  enable___cxa_atexit needs to be set to
+#                      "yes" for the correct operation of C++ destructors
+#                      but it relies upon the presence of a non-standard C
+#                      library function called __cxa_atexit.
+#                        Since not all C libraries provide __cxa_atexit the
+#                      default value of $default_use_cxa_atexit is set to
+#                      "no" except for targets which are known to be OK.
+#
+#  default_gnu_indirect_function
+#                       The default value for the $enable_gnu_indirect_function
+#                       variable.  enable_gnu_indirect_function relies
+#                      upon the presence of a non-standard gnu ifunc support
+#                      in the assembler, linker and dynamic linker.
+#                      Since not all libraries provide the dynamic linking
+#                      support, the default value of
+#                      $default_gnu_indirect_function is set to
+#                      "no" except for targets which are known to be OK.
+#
+#  gas_flag            Either yes or no depending on whether GNU as was

+# This file sets the following shell variables for use by the
+# autoconf-generated configure script:
+#
+#  cpu_type            The name of the cpu, if different from the first
+#                      chunk of the canonical target name.
+#
+#  tm_defines          List of target macros to define for all compilations.
+#
+#  tm_file             A list of target macro files, if different from
+#                      "$cpu_type/$cpu_type.h". Usually it's constructed
+#                      per target in a way like this:
+#                      tm_file="${tm_file} dbxelf.h elfos.h ${cpu_type.h}/elf.h"
+#                      Note that the preferred order is:
+#                      - specific target header "${cpu_type}/${cpu_type.h}"
+#                      - generic headers like dbxelf.h elfos.h, etc.
+#                      - specializing target headers like ${cpu_type.h}/elf.h
+#                      This helps to keep OS specific stuff out of the CPU
+#                      defining header ${cpu_type}/${cpu_type.h}.

+# This is the libgcc host-specific configuration file
+# where a configuration type is mapped to different system-specific
+# definitions and files.  This is invoked by the autoconf-generated
+# configure script.  Putting it in a separate shell file lets us skip
+# running autoconf when modifying host-specific information.
+
+# This file bears an obvious resemblance to gcc/config.gcc.  The cases
+# should be kept similar, to ease moving library-specific settings
+# from config.gcc to this file.  That is also why tmake_file is
+# left as tmake_file, rather than hmake_file, even though this library
+# switches on ${host}.
+
+# This file switches on the shell variable ${host}, and also uses the
+# following shell variables:
+#
+#  with_*              Various variables as set by configure.
+
+# This file sets the following shell variables for use by the
+# autoconf-generated configure script:
+#
+#  asm_hidden_op       The assembler pseudo-op to use for hide
+#                      lists for object files implemented in
+#                      assembly (with -fvisibility=hidden for C).
+#                      The default is ".hidden".
+#  cpu_type            The name of the cpu, if different from the first
+#                      chunk of the canonical host name.
+#  enable_execute_stack The name of a source file implementing
+#                      __enable_execute_stack.
+#  extra_parts         List of extra object files that should be compiled
+#                      for this target machine.  This may be overridden
+#                      by setting EXTRA_PARTS in a tmake_file fragment.
+#                      If either is set, EXTRA_PARTS and
+#                      EXTRA_MULTILIB_PARTS inherited from the GCC
+#                      subdirectory will be ignored.
+#  md_unwind_header    The name of a header file defining
+#                      MD_FALLBACK_FRAME_STATE_FOR.
+#  sfp_machine_header  The name of a sfp-machine.h header file for soft-fp.
+#                      Defaults to "$cpu_type/sfp-machine.h" if it exists,
+#                      no-sfp-machine.h otherwise.
+#  tmake_file          A list of machine-description-specific
+#                      makefile fragments.
+#  tm_defines          List of target macros to define for all compilations.
+#  tm_file             A list of target macro files used only for code
+#                      built for the target, not the host.  These files
+#                      are relative to $srcdir/config and must not have
+#                      the same names as files in $srcdir/../gcc/config.

+\`configure' configures package-unused version-unused to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
