In armv8l-unknown-linux-gnueabihf native, after: | commit gcc-17-2325-g4302e16581b4 | Author: Andrew Pinski andrew.pinski@oss.qualcomm.com | Date: Fri Jul 10 16:55:19 2026 -0700 | | vect: Add back testcases for trapping math with comparisons [PR36190] | | These were originally renamed to no-trapping-math-vect-*.c in r0-87196-g04b03edb56633f | but were fixed in r0-107313-gf9613c9a919462 but never added back to the | trapping versions. | ... 17 lines of the commit log omitted.
Produces 10 regressions: | | regressions.sum: | Running gcc:gcc.dg/vect/vect.exp ... | FAIL: gcc.dg/vect/vect-111.c (test for excess errors) | FAIL: gcc.dg/vect/vect-111.c -flto -ffat-lto-objects (test for excess errors) | FAIL: gcc.dg/vect/vect-ifcvt-12.c (test for excess errors) | FAIL: gcc.dg/vect/vect-ifcvt-12.c -flto -ffat-lto-objects (test for excess errors) | ... and 6 more
FAIL: gcc.dg/vect/vect-111.c (test for excess errors) Excess errors: cc1: warning: '-fassociative-math' disabled; other options take precedence
This is caused by an interaction with -ftrapping-math added by the new testcases and this from check_vect_support_and_set_flags: ``` } elseif [is-effective-target arm_neon_ok] { eval lappend DEFAULT_VECTCFLAGS [add_options_for_arm_neon ""] # NEON does not support denormals, so is not used for vectorization by # default to avoid loss of precision. We must pass -ffast-math to test # vectorization of float operations. lappend DEFAULT_VECTCFLAGS "-ffast-math" if [is-effective-target arm_neon_hw] { set dg-do-what-default run } else { set dg-do-what-default compile } ``` I am not sure what the best way of solving this. Do we just not test these testcases on arm neon? or something else?
