--- Comment #3 from rsandifo at gcc dot gnu.org <rsandifo at gcc dot gnu.org> --- Author: rsandifo Date: Tue Jan 23 10:42:32 2018 New Revision: 256977 URL: https://gcc.gnu.org/viewcvs?rev=256977&root=gcc&view=rev Log: Fix vect_float markup for a couple of tests (PR 83888) vect_float is true for arm*-*-* targets, but the support is only available when -funsafe-math-optimizations is on. This caused failures in two tests that disable fast-math. The easiest fix seemed to be to add a new target selector for "vect_float without special options". 2018-01-23 Richard Sandiford <richard.sandif...@linaro.org> gcc/ PR testsuite/83888 * doc/sourcebuild.texi (vect_float): Say that the selector only describes the situation when -funsafe-math-optimizations is on. (vect_float_strict): Document. gcc/testsuite/ PR testsuite/83888 * lib/target-supports.exp (check_effective_target_vect_float): Say that the result only holds when -funsafe-math-optimizations is on. (check_effective_target_vect_float_strict): New procedure. * gcc.dg/vect/no-fast-math-vect16.c: Use vect_float_strict instead of vect_float. * gcc.dg/vect/vect-reduc-6.c: Likewise.
