commit r15-10551-gc69799fc153421fb1e82fd90bca12d4c4bcfda6e Author: Andre Vieira <[email protected]> Date: Tue Nov 25 11:35:54 2025 +0000 arm: add extra sizes to Wstrinop-overflow-47.c warning tests A thumb2 target without a FPU like -mcpu=cortex-m3 will generate 'vector(4) char' stores which lead to warnings with sizes that weren't being allowed before by the test. This patch adds these sizes. gcc/testsuite/ChangeLog: * gcc.dg/Wstringop-overflow-47.c: Adjust warnings to allow for 32-bit stores.
