Subject: Re: [llvm-dev] RFC: Inline expansion of memcmp vs call to standard library
Can I make another suggestion: create an intrinsic for memory equality, e.g. llvm.memcmp_eq.p0i8.p0i8.i64(i8*a, i8*b, i64 len). This intrinsic would return zero if the memory regions are equal...

CFI directives for callee saved registers
Hello,
I've made changes to the prologue to not spill callee saved gprs to the
stack but rather spill them to unused vector registers. I'm not sure how
to handle this in the cfi directives. Originally, we would use cfi_offset
to give an offset of where it is saved on the stack. I tried to instead
use the cfi_restore directive. As the docs say ".cfi_restore says that the

However, it does NOT return any notion of "greater" or "less".
Many applications require only determining equality, rather than a total
ordering. Given that
