It solved my question, thank you.


Best regards,

I think that:

   -mllvm -print-after-all

does that you need.  It is "very" verbose though and you might prefer to use:

   -mllvm -print-after=<selected-passes>

Use '-mllvm -help' or '-mllvm --help-hidden' to see all the options.

Dear llvm-dev,

I am trying to debug some passes , these passes are added to
legacy::PassManager(MPM) in Clang's lib/CodeGen/BackendUtil.cpp  :


//******
void EmitAssemblyHelper::CreatePasses() {
//******
   if (CodeGenOpts.MemSafety) {
     //
     // Add passes that record information about run-time checks.
     //
     MPM->add (createCommonMSCInfoPass());
     MPM->add (createSAFECodeMSCInfoPass());
//******

Could I dump the output LLVM IR after each pass in PassManager MPM?

Best regards,
Zhengyang.
