--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Christophe Lyon <cl...@gcc.gnu.org>: https://gcc.gnu.org/g:20c25919132b497c3a46a4bc4044f65b6459b99e commit r16-562-g20c25919132b497c3a46a4bc4044f65b6459b99e Author: Christophe Lyon <christophe.l...@linaro.org> Date: Tue Apr 8 16:24:18 2025 +0000 testsuite: arm: Fix unsigned-extend-2.c [PR116445] The test was designed to pass with thumb2, but code generation changed with the introduction of Low Overhead Loops, so the test can fail if one overrides the flags when running the testsuite. In addition, useless subtract / extension instructions require -O2 to remove them (-O is not sufficient), so replace -O with -O2 in dg-options. arm_thumb2_ok_no_arm_v8_1m_lob does not do what the test needs (it can fail because some flags conflict, rather than because lob are supported, and we do not need to check runtime support in this test anyway), so the patch reverts back to arm_thumb2_ok. Finally, replace the scan-assembler directives with check-function-bodies, checking both types of code generation (with and without LOL). Depending on architecture version, the two insns and r0, r1, r0, lsr #1 ands r3, r3, #255 can be swapped, so accept both orders. gcc/testsuite/ChangeLog: PR target/116445 * gcc.target/arm/unsigned-extend-2.c: Fix dg directives.
