2018-10-18Add -std=c2x, -std=gnu2x, -Wc11-c2x-compat, C2X _Static_assert support.Joseph Myers24-28/+237
Now new features are starting to be added to a C2X draft (in the C2x branch of the C standard git repository, no public WG14 document yet), it's time to add -std=c2x and associated options to GCC for use in enabling C2X features. This patch adds the expected set of options: -std=c2x, -std=gnu2x, -Wc11-c2x-compat. A first C2X feature is added (the only one so far in the repository that's obviously relevant to GCC): support (as in C++) for the string constant to be omitted in _Static_assert. This feature is duly also supported as an extension in earlier standard modes (diagnosed with -pedantic, unless -Wno-c11-c2x-compat is given, or with -Wc11-c2x-compat even in C2X mode). Bootstrapped with no regressions on x86_64-pc-linux-gnu. gcc/ * doc/cpp.texi (__STDC_VERSION__): Document C2X handling. * doc/invoke.texi (-std=c2x, -std=gnu2x): Document new options. * doc/standards.texi (C Language): Document C2X. * dwarf2out.c (highest_c_language), config/rl78/rl78.c (rl78_option_override): Handle "GNU C2X" language name. gcc/c/ * c-errors.c (pedwarn_c11): New function. * c-parser.c (disable_extension_diagnostics): Save warn_c11_c2x_compat and set it to 0.

(For the reasons it took so long to get to ballot and publication, see the WG14 convenor's report to the last SC22 plenary - SC22 N5297 - where it references "A troubling new trend where ISO CS has begun enforcing undocumented rules that are approved neither by the TMB nor by the WG 14 editors, leading to a decrease in the usefulness of standards documents.".)

2018-10-15diagnostics: add minimum width to left margin for line numbersDavid Malcolm16-60/+152
This patch adds a minimum width to the left margin used for printing line numbers. I set the default to 6. Hence rather than: some-filename:9:1: some message 9 | some source text | ^~~~~~~~~~~~~~~~ some-filename:10:1: another message 10 | more source text | ^~~~~~~~~~~~~~~~ we now print: some-filename:9:42: some message 9 | some source text | ^~~~~~~~~~~~~~~~ some-filename:10:42: another message 10 | more source text | ^~~~~~~~~~~~~~~~ This implicitly fixes issues with margins failing to line up due to different lengths of the number when we haven't read the full file yet and so don't know the highest possible line number, for line numbers up to 99999. Doing so adds some whitespace on the left-hand side, for non-huge files, at least. I believe that this makes it easier to see where each diagnostic starts, by visually breaking things up at the leftmost column; my hope is to make it easier for the eye to see the different diagnostics as if they were different "paragraphs". gcc/ChangeLog: * common.opt (fdiagnostics-minimum-margin-width=): New option. * diagnostic-show-locus.c (layout::layout): Apply the minimum margin width. (layout::start_annotation_line): Only print up to 3 of the margin character, to avoid touching the left-hand side.

2018-10-12[AArch64] Support zero-extended move to FP registerWilco Dijkstra5-13/+68
The popcount expansion uses SIMD instructions acting on 64-bit values. As a result a popcount of a 32-bit integer requires zero-extension before moving the zero-extended value into an FP register. This patch adds support for zero-extended int->FP moves to avoid the redundant uxtw. Similarly, add support for 32-bit zero-extending load->FP register and 32-bit zero-extending FP->FP and FP->int moves. Add a missing 'fp' arch attribute to the related 8/16-bit pattern and fix an incorrect type attribute. To complete zero-extended load support, add a new alternative to load_pair_zero_extendsidi2_aarch64 to support LDP into FP registers too. int f (int a) { return __builtin_popcount (a); } Before: uxtw x0, w0 fmov d0, x0 cnt v0.8b, v0.8b addv b0, v0.8b fmov w0, s0 ret After: fmov s0, w0 cnt v0.8b, v0.8b addv b0, v0.8b fmov w0, s0 ret Passes regress & bootstrap on AArch64. gcc/ * config/aarch64/aarch64.md (zero_extendsidi2_aarch64): Add alternatives to zero-extend between int and floating-point registers.
