[RFC PATCH 4/7] powerpc: add CFUNC assembly label annotation
Nicholas Piggin
npiggin at gmail.com
Tue Sep 20 00:01:46 AEST 2022
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.
