[llvm-commits] [PATCH] LTO code generator options: --verbose

[Viktor Kutuzov]

I have been thinking of how people will set up and maintain complex builds with our tools.
Once in a while something will go wrong and it should be a way to figure out what's going on behind the scene.

The idea is to have a special "verbose" mode for builds trouble shooting.
It is a run-time mode, not a debug; the toolchain does the regular things but provides detailed messages along the way.
Gold plugin runs other tools, so from this perspective it is helpful to be able to see what exact program get ran with what exact 
parameters. I planned to add passing the verbose flag (if set) down to the toolchain as well, just wanted to separate patches.

Does it make sense?

Why do you need this? Or rather, when would a user want to specify this?

If this is just debugging info, why not use DEBUG() from
llvm/Support/Debug.h?
