[llvm-dev] Question on GlobalISel Intermediate invariants

I'm not aware of a clang option to dump out IR between specific passes.
I think the one way to do it is to let clang generate llvm-ir, and feed that into llc, and let llc print out the IR after the pass you're interested in, e.g.:
clang t.c -o- -S -emit-llvm | llc -global-isel -print-after=irtranslator
If you want to see how the IR evolves after each pass, you can use the llc command line option -print-after-all.
Is this what you were looking for?
