Hi,
Changes in v3: Droped special case for thumb1_extendqisi2 as it's only thumb1_extendhisi2 that causes problem for gen_rtx_SIGN_EXTEND. Changes in v2: Updated the patch to also fix the Cortex-M55 issue reported in PR115253 and updated the commit message to mention the PR number. Initial issue reported at https://linaro.atlassian.net/browse/GNU-1205. Ok for these branches? - releases/gcc-11 - releases/gcc-12 - releases/gcc-13 - releases/gcc-14 - trunk Kind regards, Torbjörn and Yvan
