--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:52fa771758635d9c53cddb9116e5a66fae592230 commit r12-5078-g52fa771758635d9c53cddb9116e5a66fae592230 Author: Andrew Pinski <apin...@marvell.com> Date: Sat Nov 6 06:29:13 2021 +0000 aarch64: [PR101529] Fix vector shuffle insertion expansion The function aarch64_evpc_ins would reuse the target even though it might be the same register as the two inputs. Instead of checking to see if we can reuse the target, just use the original input directly. Committed as approved after bootstrapped and tested on aarch64-linux-gnu with no regressions. PR target/101529 gcc/ChangeLog: * config/aarch64/aarch64.c (aarch64_evpc_ins): Don't use target as an input, use original one. gcc/testsuite/ChangeLog: * c-c++-common/torture/builtin-convertvector-2.c: New test. * c-c++-common/torture/builtin-shufflevector-2.c: New test.
