X86: Add -mcopy-reloc to avoid copy relocation

On x86, copy relocation is used in executable to access external data
defined in shared object as if it is defined locally. At run-time,
dynamic linker copies symbol data from shared object to executable and
its references from shared objects are resolved by GLOB_DAT relocation.
Since the copy of symbol data in executable is writable even if the
original symbol in shared object is read-only, this is a potential
security risk.

We can avoid copy relocation by always using PIC model to access
external data symbol.  If the external symbol is defined locally in
executable, linker can optimize instructions on memory operand with
GOTPCRELX/GOT32X relocation against external symbol into a different
form on immediate operand.

Without copy relocation, external symbols in executable are accessed
indirectly via the GOT slot. Even when the symbol is defined locally,
it is still referenced indirectly through a register. However, there
are a few side benefits:

1. Without copy relocation in executable for external symbol defined
in shared object, symbol size can be increased while still providing
backward binary compatibility.
2. Since protected symbols in shared objects are no longer copied to
executable at run-time, references of protected symbols within shared
objects can be resolved without GOT.

C: fix logic within c_expr::get_location

In r251239 I added a c_expr::get_location method for use by
c_parser_expr_list for building the vec<location_t> for
an expression list, rather than using the location of the first token.

When determining whether to use the location within the tree node,
or fall back to the range in the c_expr, I used EXPR_CAN_HAVE_LOCATION,
rather than EXPR_HAS_LOCATION.  This meant that any tree nodes of kinds
that *can* have a location but which erroneously had
   EXPR_LOCATION (value) == UNKNOWN_LOCATION
had that value added to the vec<location_t>, leading to missing
location information when reporting on the issue
(seen with gcc.dg/Wtraditional-conversion-2.c for m68k).

This patch addresses this in two ways:

(a) it fixes the specific issue in this failing test case, by
    setting up the location properly on the EXCESS_PRECISION_EXPR.

(b) updating c_expr::get_location by only using the EXPR_LOCATION
    if it's sane.  Arguably this is papering over bugs, but they are
    pre-existing ones exposed by r251239, and I'd rather have this
    fix in place than play whack-a-mole on any other such "missing
    location" bugs that are lurking in the codebase.

gcc/c/ChangeLog:
* c-tree.h (c_expr::get_location) Use EXPR_HAS_LOCATION rather
than CAN_HAVE_LOCATION_P when determining whether to use the
location_t value within "value".

Make more use of paradoxical_subreg_p

This patch makes more use of the existing paradoxical_subreg_p
predicate and also adds a version that operates on outer and
inner modes.

Some of the affected tests were based on GET_MODE_SIZE rather than
GET_MODE_PRECISION and so the patch could change the result for modes
that have the same size but different precisions.  I think in each
case the change should be a no-op or more correct, since a mode with
precision N bits can't be expected to hold all of a mode with precision
M>N bits.

The patch changes the branch taken in simplify_subreg for modes with
equal precision, but the new form matches the commentary more closely.
Both branches should be equally good in that situation.

C: use full locations within c_parser_expr_list's vec<location_t>

The previous patch uncovered a bug in how c_parser_expr_list builds the
vec<location_t>: it was only using the location of the first token
within each assignment-expression in the expr-list.

This shows up in e.g. this -Wformat warning, where only part of the
2nd param is underlined:

   printf("hello %i", (long)0);
                 ~^   ~
                 %li

This patch fixes c_parser_expr_list to use the full range of
each assignment-expression in the list for the vec<location_t>, so
that for the above we print:

   printf("hello %i", (long)0);
                 ~^   ~~~~~~~
                 %li

gcc/c/ChangeLog:
* c-parser.c (c_parser_expr_list): Use c_expr::get_location ()
rather than peeking the location of the first token.
* c-tree.h (c_expr::get_location): New method.

gcc/testsuite/ChangeLog:
* gcc.dg/format/diagnostic-ranges.c (test_mismatching_types):
Update expected result to show all of "(long)0" being underlined.
* gcc.dg/plugin/diagnostic-test-string-literals-1.c
(test_multitoken_macro): Update expected underlining.

git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@251239 138bc75d-0d04-0410-961f-82ee72b054a4

c-family/c/c++: pass optional vec<location_t> to c-format.c

This patch passes along the vec<location_t> of argument locations
at a callsite from the C frontend to check_function_arguments and
from there to c-format.c, so that we can underline the pertinent
argument to mismatched format codes even for tree codes like decls
and constants which lack a location_t for their usage sites.

This takes e.g.:

    printf("hello %i %i %i ", foo, bar, baz);
                     ~^
                     %s

to:

    printf("hello %i %i %i ", foo, bar, baz);
                     ~^            ~~~
                     %s

which is useful for cases where there's more than one variadic argument.

gcc/c-family/ChangeLog:
* c-common.c (check_function_arguments): Add "arglogs" param; pass
it to check_function_format.

(class argument_parser): New field "arglocs".
(argument_parser::argument_parser): Add "arglocs_" param and use
it to initialize new field.
(argument_parser::check_argument_type): Pass new arglocs field to
check_format_types.
(check_format_info_main): Add param "arglocs", and use it when

(check_format_types): Add param "arglocs"; use it if non-NULL when
!EXPR_HAS_LOCATION (cur_param) to get at location information.

Simplify pad_below implementation

This patch simplifies the alignment calculations in pad_below.
The first arm of the "if" was:

- taking GET_MODE_BITSIZE (always equal to GET_MODE_SIZE * BITS_PER_UNIT),
- rounding up to the next multiple of PARM_BOUNDARY
- converting bits to bytes and
- subtracting the GET_MODE_SIZE

so was in effect calculating the number of bytes needed to round
GET_MODE_SIZE up to (PARM_BOUNDARY / BITS_PER_UNIT).  That can be
done more directly as -size & (align - 1), which is easier to
convert to variable-sized modes.

Remove the frame size argument from function_prologue/epilogue

Later patches will add support for frame sizes that are a run-time
invariant but not a compile-time constant.  This then raised the
question of whether the frame size argument to the function_prologue/
epilogue hooks should be updated accordingly.

It turned out that only two targets actually used this argument, and
even they got other frame-related information from the cached machine
structure.  This patch therefore removes the argument and makes the two
targets use get_frame_size () instead.

jit: make simpler reproducers

The C reproducers generated by gcc_jit_context_dump_reproducer_to_file
contain numerous pointer values (from %p) to ensure uniqueness of the
identifiers, but this makes them less readable than they could be.

This patch updates reproducer::make_identifier so that the pointer
is only added if it's necessary for uniqueness.

gcc/jit/ChangeLog:
* jit-recording.c (class gcc::jit::reproducer): Rename field
"m_identifiers" to "m_map_memento_to_identifier".  Add field
