testsuite: Prepare for -std=gnu23 default

2024-10-16T16:48:24+00:00

Now that C23 support is essentially feature-complete, I'd like to
switch the default language version for C compilation to -std=gnu23.

This requires updating a large number of testcases that fail with the
new language version if left unchanged.  In this patch, update most of
the tests for which there is a safe change that works both before and
after the update to default language version - typically adding the
option -std=gnu17 or -Wno-old-style-definition to the tests.  (There
are also a few tests where I'd like to investigate further why they
fail with -std=gnu23, or where I think such failures show an actual
bug to fix before changing the default language version, or where it
seems more appropriate to make a testcase change that would result in
failures in the absence of the language version change rather than
just adding an option that does nothing with the gnu17 default.)

The libffi test fixes have also been submitted upstream:
.

Most of the failures requiring such changes are for one of two
reasons:

* Unprototyped function declarations with () (meaning the same as
  (void) in C23 mode) for a function then called with arguments.

* Old-style function definitions, which warn by default in C23 mode,
  so resulting in test failures for the unexpected warnings.

Other reasons for failures include:

* Tests with their own definitions of bool, true and false.

* Tests of diagnostics (often with -pedantic) in cases where C23 has
  changed semantics, such as:

  - tag compatibility for structs;
  - enum values out of range of int;
  - handing of qualified array types;
  - decimal floating types formerly needing -pedantic diagnostics, but
    being standard in C23.

Bootstrapped with no regressions for x86_64-pc-linux-gnu.

dwarf2: add hooks for architecture-specific CFIs

2024-09-23T14:37:05+00:00

Architecture-specific CFI directives are currently declared an processed
among others architecture-independent CFI directives in gcc/dwarf2* files.
This approach creates confusion, specifically in the case of DWARF
instructions in the vendor space and using the same instruction code.

Such a clash currently happen between DW_CFA_GNU_window_save (used on
SPARC) and DW_CFA_AARCH64_negate_ra_state (used on AArch64), and both
having the same instruction code 0x2d.
Then AArch64 compilers generates a SPARC CFI directive (.cfi_window_save)
instead of .cfi_negate_ra_state, contrarilly to what is expected in
[DWARF for the Arm 64-bit Architecture (AArch64)](https://github.com/
ARM-software/abi-aa/blob/main/aadwarf64/aadwarf64.rst).

This refactoring does not solve completely the problem, but improve the
situation by moving some of the processing of those directives (more
specifically their output in the assembly) to the backend via 2 target
hooks:
- DW_CFI_OPRND1_DESC: parse the first operand of the directive (if any).
- OUTPUT_CFI_DIRECTIVE: output the CFI directive as a string.

Additionally, this patch also contains a renaming of an enum used for
return address mangling on AArch64.

gcc/ChangeLog:

	* config/aarch64/aarch64.cc
	(aarch64_output_cfi_directive): New hook for CFI directives.
