--- Comment #12 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Earnshaw <rearn...@gcc.gnu.org>: https://gcc.gnu.org/g:1d2257dc850d088f6d9267b4624ba08533ab2475 commit r15-8649-g1d2257dc850d088f6d9267b4624ba08533ab2475 Author: Richard Earnshaw <rearn...@arm.com> Date: Fri Mar 21 15:20:03 2025 +0000 arm: testsuite: make unaligned-memcpy-*.c executable tests [PR91614] These tests have been looking for a very specific instruction sequence which has the tendency to be fairly unstable as a result. But what is more interesting is that the the tests must not contain instructions that can't be used for unaligned data, and whether or not the copy is executed correctly. So make these tests executable and scan the assembler only to confirm the absence of instructions that must not be used when the data is not aligned. These tests also used to be restricted to targets that support unaligned accesses (because you get very different code otherwise). But now we've made the tests executable and to check for the absence of problem instructions, just falling back to memcpy *is* an acceptable implementation. So remove the requirement for unaligned accesses. gcc/testsuite: PR target/91614 * gcc.target/arm/unaligned-memcpy-1.c: Make the test executable. Only scan for the absence of instructions that cannot access misaligned data. Remove constraint of having unaligned accesses. * gcc.target/arm/unaligned-memcpy-2.c: Likewise. * gcc.target/arm/unaligned-memcpy-3.c: Likewise. * gcc.target/arm/unaligned-memcpy-4.c: Likewise.
