From 7593dae69ba06ffe63bc22d26c16b19aa9ab24e8 Mon Sep 17 00:00:00 2001 From: Andre Vieira Date: Thu, 6 Jun 2024 16:02:50 +0100 Subject: arm: Add .type and .size to __gnu_cmse_nonsecure_call [PR115360] This patch adds missing assembly directives to the CMSE library wrapper to call functions with attribute cmse_nonsecure_call. Without the .type directive the linker will fail to produce the correct veneer if a call to this wrapper function is to far from the wrapper itself. The .size was added for completeness, though we don't necessarily have a usecase for it. libgcc/ChangeLog: PR target/115360 * config/arm/cmse_nonsecure_call.S: Add .type and .size directives.
