commit r16-6751-g7a456056ff9c2edc67cfcdf7bb8fe86176c66ec7 Author: Andrew Pinski <[email protected]> Date: Tue Jan 13 11:43:42 2026 -0800 testsuite/aarch64: Fix aarch64/signbitv2sf.c [PR122522] The problem here is after some heurstics changes the check loop is now unrolled so we eliminate the array. This means the check for not having -2147483648 no longer works as we don't handle SLP in this case. So the best option is to force the check loop not to unroll (no vectorize) as this is just testing we SLP the normal signbit places rather than dealing with the checking loop. Pushed as obvious after testing the testcase on aarch64-linux-gnu. PR testsuite/122522 gcc/testsuite/ChangeLog: * gcc.target/aarch64/signbitv2sf.c (main): Disable unrolling and vectorizer for the checking loop.
