Hi all, I wrote 2 passes and I want to make run llvm run the passes in this order: -mem2reg -load=…/mypass1.dylib -mypass1 -load=…/mypass2.dylib -mypass2 -O1 -O2 -O3 I know I can do this by manually passing them as an argument to opt. Is there any way to force this sequence directly from clang? I am asking this because I am trying to compile a program and I can specify in the ./configure
