Note that the assert is triggered only with checking, so release-build compilers do not see it. I have bisected it down to: commit edafb35bdadf309ebb9d1eddc5549f9e1ad49c09 Author: H.J. Lu <hjl.tools@gmail.com> Date: Wed Jun 2 07:15:45 2021 -0700 x86: Convert CONST_WIDE_INT/CONST_VECTOR to broadcast 1. Update move expanders to convert the CONST_WIDE_INT and CONST_VECTOR operands to vector broadcast from an integer with AVX. 2. Add ix86_gen_scratch_sse_rtx to return a scratch SSE register which won't increase stack alignment requirement and blocks transformation by the combine pass. [...rest of the commit message trimmed...] At this point I do not plan to attempt to come up with a reduced testcase. ^ permalink raw reply [flat|nested] 6+ messages in thread
