I have my own llvm pass which requires mem2reg. It worked fine with opt. However, I was trying to make it work with clang as I needed it to run some spec cpu benchmarks. Is there any way that I can mention mem2reg (PromotePass) pass as a pre-requisite in my own pass's implementation?

...t... It is not guaranteed to do anything to any particular piece of code, so relying on it seems very unreliable, I would think. -- Mats On 22 March 2016 at 04:32, Kevin Hu via llvm-dev <llvm-dev at lists.llvm.org> wrote: > Hi, > > > Is there any way that I can mention mem2reg (PromotePass) pass as a > > pre-requisite in my own pass's implementation? > > I think you can consider overriding the > Pass::getAnalysisUsage(AnalysisUsage &) > method.

Hi, I was trying to pass llvm option -mem2reg to clang using -mllvm and I found the following error: clang (LLVM option parsing): Unknown command line argument '-mem2reg'. Try: 'clang (LLVM option parsing) -help' clang (LLVM option parsing): Did you mean '-debug'? I would appreciate if anyone could help me. -- Syed Rafiul Hussain

I'll see if I can reproduce it outside our setup. Does it depend on machine architecture? I generally use x86... regards,   Fedor. > > Thanks.
