2018-10-18Add -std=c2x, -std=gnu2x, -Wc11-c2x-compat, C2X _Static_assert support.Joseph Myers3-1/+17
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.

This patch makes references in the manual to C17 reflect it having been published in July 2018. (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 Malcolm1-0/+6
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.

2018-10-04Add -fopt-info-internalsDavid Malcolm1-7/+24
This patch introduces a verbosity level to dump messages: "user-facing" vs "internals". By default, messages at the top-level dump scope are "user-facing", whereas those that are in nested scopes are implicitly "internals", and are filtered out by -fopt-info unless a new "-internals" sub-option of "-fopt-info" is supplied (intended purely for use by GCC developers). Dumpfiles are unaffected by the change. Given that the vectorizer is the only subsystem using AUTO_DUMP_SCOPE (via DUMP_VECT_SCOPE), this only affects the vectorizer. Filtering out these implementation-detail messages goes a long way towards making -fopt-info-vec-all more accessible to advanced end-users; the follow-up patch restores the most pertinent missing details. gcc/ChangeLog: * doc/invoke.texi (-fopt-info): Document new "internals" sub-option. * dump-context.h (dump_context::apply_dump_filter_p): New decl. * dumpfile.c (dump_options): Update for renaming of MSG_ALL to MSG_ALL_KINDS.

2018-10-01Add a hook to support telling the mid-end when to probe the stack.Tamar Christina2-3/+7
This patch adds a hook to tell the mid-end about the probing requirements of the target. On AArch64 we allow a specific range for which no probing needs to be done. This same range is also the amount that will have to be probed up when a probe is needed after dropping the stack. Defining this probe comes with the extra requirement that the outgoing arguments size of any function that uses alloca and stack clash be at the very least 8 bytes. With this invariant we can skip doing the zero checks for alloca and save some code. A simplified version of the AArch64 stack frame is: +-----------------------+ | | | | | | +-----------------------+ |LR | +-----------------------+ |FP | +-----------------------+ |dynamic allocations | -\ probe range hook effects these +-----------------------+ --\ and ensures that outgoing stack |padding | -- args is always > 8 when alloca. +-----------------------+ ---/ Which means it's always safe to probe |outgoing stack args |-/ at SP +-----------------------+ This allows us to generate better code than without the hook without affecting other targets. With this patch I am also removing the stack_clash_protection_final_dynamic_probe hook which was added specifically for AArch64 but that is no longer needed. gcc/ PR target/86486 * explow.c (anti_adjust_stack_and_probe_stack_clash): Support custom probe ranges. * target.def (stack_clash_protection_alloca_probe_range): New.

2018-09-19Remove constant vec_select restriction.Andrew Stubbs1-5/+6
The vec_select operator is documented to require a const_int for the lane selector operand, but GCN has an instruction that can select the lane at runtime, so it seems reasonable to remove this restriction. This patch simply replaces assertions that the operand is constant with early exits from the optimizers. I think it's reasonable that vec_select with a non-constant operand cannot be optimized, yet. Also included is the necessary documentation tweak. 2018-09-19 Andrew Stubbs <ams@codesourcery.com> gcc/ * doc/rtl.texi: Adjust vec_select description. * simplify-rtx.c (simplify_binary_operation_1): Allow VEC_SELECT to use non-constant selectors.
