--- Comment #4 from Bernhard Reutner-Fischer <aldot at gcc dot gnu.org> --- Author: aldot Date: Wed Sep 5 15:31:13 2018 New Revision: 264128 URL: https://gcc.gnu.org/viewcvs?rev=264128&root=gcc&view=rev Log: PR52665 do not let .ident confuse assembler scan tests A branch with a name matching scan-assembler pattern triggers inappropriate FAIL. E.g. branch fixups-testsuite and - gcc.target/i386/pr65871-?.c (scan-assembler-not "test") - gcc.target/i386/pr41442.c (scan-assembler-times "test|cmp" 2) etc. This is a recurring problem as can be seen by some -fno-ident additions by commits from e.g. Michael Meissner over the years: builtins-58.c, powerpc/pr46728-?.c The patch below adds -fno-ident if a testcase contains one of scan-assembler, scan-assembler-not or scan-assembler-times. Regression tested on x86_64-unknown-linux on a fixups-testsuite branch where it fixes several false FAILs without regressions. gcc/testsuite/ChangeLog 2016-06-18 Bernhard Reutner-Fischer <al...@gcc.gnu.org> PR testsuite/52665 * lib/gcc-dg.exp (gcc-dg-test-1): Iterate over _required_options. * lib/target-supports.exp (scan-assembler_required_options, scan-assembler-not_required_options, scan-assembler-times_required_options): Add -fno-ident. * lib/scanasm.exp (scan-assembler-times): Fix error message. * c-c++-common/ident-0a.c: New test. * c-c++-common/ident-0b.c: New test. * c-c++-common/ident-1a.c: New test. * c-c++-common/ident-1b.c: New test. * c-c++-common/ident-2a.c: New test. * c-c++-common/ident-2b.c: New test.
