It is my understanding that we only communicate the calling convention
to be used via LLVM IR
and LLVM handles generation of the save/restore instructions required
for the call.
So indeed neither the macro nor this function would be used there. But I
gathered that just by skimming
the LLVM code
But this only includes the NCG. What about the LLVM backend? For LLVM I
only found in compiler/llvmGen/LlvmCodeGen/CodeGen.hs function
definition getTrashRegs which makes use of function callerSaves which is
defined in includes/CodeGen.Platform.hs:
callerSaves :: GlobalReg -> Bool
#if defined(CALL
What you want is not the macro but this function:
https://hackage.haskell.org/package/ghc-8.6.5/docs/src/X86.Regs.html#callClobberedRegs
whose results depend on the System ABI.

Hi all,
I'm wondering what GHC assumes about vector registers XMMi, YMMi, and ZMMi used
