I am not aware of a good reason for that (the first one is created with PassManagerBuilder::populateFunctionPassManager() and the second one with PassManagerBuilder::populateModulePassManager()). > > You can look at AddOptimizationPasses() in opt.cpp. As far as I understand, the two passmanager do not interleave their passes. It first runs all the function passes and below. Then all the module passes. So if you specify: opt -mymodulepass0 -myfunctionpass -mymodulepass1 What you actually get is: 1. myfunctionpass on each fun...

Hi, I'm a PhD student doing phase ordering as part of my PhD topic and I would like to ask some questions about LLVM. Executing the following command to see what passes does OPT execute when targeting a SPARC V8 processor: /opt/clang+llvm-3.7.1-x86_64-linux-gnu-ubuntu-15.10/bin/llvm-as < /dev/null | /opt/clang+llvm-3.7.1-x86_64-linux-gnu-ubuntu-15.10/bin/opt -O3 -march=sparc -mcpu=v8
