[llvm-dev] How to print all pass when using -flto floag ?
Hi We knew that "clang -mllvm -debug-pass=Structure ..." can print all pass' name. But, when we use LTO , -flto flag and gold plugin. I found that the option " -debug-pass=Structure" would not pass to ld. so it would not print all the LTO pass's name. -------------- next part -------------- An HTML attachment was scrubbed...

I am not sure but passing either of "-Wl,-mllvm,-debug-pass=Structure" "-Wl,-mllvm,-plugin-opt,-debug-pass=Structure" "-Wl,-mllvm,-plugin-opt=-debug-pass=Structure" may work.
