2017-10-25C: detect more missing semicolons (PR c/7356)David Malcolm8-7/+117
c_parser_declaration_or_fndef has logic for parsing what might be either a declaration or a function definition. This patch adds a test to detect cases where a semicolon would have terminated the decls as a declaration, where the token that follows would start a new declaration specifier, and updates the error message accordingly, with a fix-it hint. This addresses PR c/7356, fixing the case of a stray token before a #include that previously gave inscrutable output, and improving e.g.: int i int j; from: t.c:2:1: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'int' int j; ^~~ to: t.c:1:6: error: expected ';' before 'int' int i ^ ; int j; ~~~ gcc.dg/noncompile/920923-1.c needs a slight update, as the output for the first line changes from: 920923-1.c:2:14: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'unsigned' typedef BYTE unsigned char; /* { dg-error "expected" } */ ^~~~~~~~ to: 920923-1.c:2:13: error: expected ';' before 'unsigned' typedef BYTE unsigned char; /* { dg-error "expected" } */ ^~~~~~~~~ ; 920923-1.c:2:1: warning: useless type name in empty declaration typedef BYTE unsigned char; /* { dg-error "expected" } */ ^~~~~~~ The patch also adds a test for PR c/44515 as a baseline. gcc/c/ChangeLog: PR c/7356 * c-parser.c (c_parser_declaration_or_fndef): Detect missing semicolons. gcc/testsuite/ChangeLog: PR c/7356 PR c/44515 * c-c++-common/pr44515.c: New test case. * gcc.dg/pr7356-2.c: New test case. * gcc.dg/pr7356.c: New test case. * gcc.dg/spellcheck-typenames.c: Update the "singed" char "TODO" case to reflect changes to output. * gcc.dg/noncompile/920923-1.c: Add dg-warning to reflect changes to output.

2017-10-24Cleanup autopref schedulingWilco Dijkstra3-99/+25
r253236 broke AArch64 bootstrap. Earlier revision r253071 changed scheduling behaviour on AArch64 as autopref scheduling no longer checks the base. This patch fixes the bootstrap failure and cleans up autopref scheduling. The code is greatly simplified. Sort accesses on the offset first, and only if the offsets are the same fall back to other comparisons in rank_for_schedule. This doesn't at all restore the original behaviour since we no longer compare the base address, but it now defines a total sorting order. More work will be required to improve the sorting so that only loads/stores with the same base are affected. gcc/ PR rtl-optimization/82396 * gcc/haifa-sched.c (ready_sort_real): Remove qsort workaround.

2017-10-24PR60580: Fix frame pointer option magicWilco Dijkstra2-24/+27
To fix PR60580 simplify the logic in aarch64_override_options_after_change_1 (). If the frame pointer is enabled, set it to a special value that behaves similar to frame pointer omission. If we don't do this all leaf functions will get a frame pointer even if flag_omit_leaf_frame_pointer is set. If flag_omit_frame_pointer has this special value, we must force the frame pointer if not in a leaf function. We also need to force it in a leaf function if flag_omit_frame_pointer is not set or if LR is used. Doing this allows both -fomit-frame-pointer and -fomit-leaf-frame-pointer to be independently set and changed in each function with the expected behaviour. gcc/ PR middle-end/60580 * config/aarch64/aarch64.c (aarch64_frame_pointer_required) Check special value of flag_omit_frame_pointer.
