[EXTERNAL] Get llvm-mca results inside opt?
...in input have already been lowered into a sequence of mca::Instruction. The only way currently to obtain an `mca::Instruction` is by calling method `mca::InstrBuilder::createInstruction()` [1] on every instruction in input (see for example how it is done in llvm-mca.cpp [2]). Unfortunately method `createInstructions()` only works on `MCInst&`. This strongly limits the usability of llvm-mca as a library; the expectation/assumption is that instructions have already been lowered to a sequence of MCInst. Basically the only supported scenarios are: - We have reached code emission stage and instructions have al...

Get llvm-mca results inside opt?
Hi, I am trying to generate performance models for specific pieces of code like an omp.outlined function. Lets say I have the following code: start_collect_parallel_for_data(-1.0,-1.0,-1.0, size, “tag for this region”); #pragma omp parallel for for(auto i = 0; i < size; ++i){ // … do work } stop_collecting_parallel_for_data(); The omp region will get outlined into a new function and what I
