[llvm-dev] LLVM log file

[Adrian Vogelsgesang via llvm-dev]

I used “-print-changed”, “-print-before-all”, “print-after-all” last time I wanted to see the passes together with their inout/output IR modules.

In my case, I used them through “clang++”, i.e. I had to prefix them with “-mllvm”
> clang++ test_file.cpp -mllvm -print-after-all

I don't know if it's exhaustive but there's the "remarks" feature:

Dear all,

Good morning. I want to know whether LLVM creates any log file consisting of applied optimizations in the optimization phase. It will be really useful for the researchers who work on compilers, formal methods, etc.

Thanks,
Sudakshina
