From 4e991e3c16a350d1eeffc100ce3fb25292596d03 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Sat, 8 Apr 2023 12:17:50 +1000 Subject: powerpc: add CFUNC assembly label annotation This macro is to be used in assembly where C functions are called. pcrel addressing mode requires branches to functions with a localentry value of 1 to have either a trailing nop or @notoc. This macro permits the latter without changing callers.
