--- Comment #2 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:d3d0fcb652748191714e4c0b2541e977a7fc7bd7 commit r14-9248-gd3d0fcb652748191714e4c0b2541e977a7fc7bd7 Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Mar 1 11:04:51 2024 +0100 bitint: Handle VCE from large/huge _BitInt SSA_NAME from load [PR114156] When adding checks in which case not to merge a VIEW_CONVERT_EXPR from large/huge _BitInt to vector/complex etc., I missed the case of loads. Those are handled differently later. Anyway, I think the load case is something we can handle just fine, so the following patch does that instead of preventing the merging gimple_lower_bitint; we'd then copy from memory to memory and and do the vce only on the second one, it is just better to vce the first one. 2024-03-01 Jakub Jelinek <ja...@redhat.com> PR middle-end/114156 * gimple-lower-bitint.cc (bitint_large_huge::lower_stmt): Allow rhs1 of a VCE to have no underlying variable if it is a load and handle that case. * gcc.dg/bitint-96.c: New test.
