[LLVMdev] Does LLVM have Instruction Performance Model?

[Jonas Wagner]

Hi,

there is a rather basic CostModelAnalysis
<http://llvm.org/docs/doxygen/html/CostModel_8cpp_source.html>.

It gives you a cost estimate, where higher numbers generally mean less
throughput. See also other discussions on this list regarding how to use it
[1].

This is the only model I'm aware of. I'd be interested myself whether there
are others.

Cheers,
Jonas
