Subject: Re: [PATCH] powerpc: Define USE_PPC64_NOTOC iff compiler and linker also supports it
Date: Tue, 9 Nov 2021 21:35:08 +1030 [thread overview]

I have a question about powerpc64/ppc-mcount.S. Why is the assembly
wrapper using ENTRY and a NOTOC call? By using ENTRY you are saying
that calls to _mcount must have r2 valid. Given that r2 is valid, why
then use NOTOC?
