[cfe-dev] Question about passing -v -save-temps cmd args to clang++

[Anton Korobeynikov via cfe-dev]

Hello

> Question: When I pass `-v save-temps` options to clang++, I was expecting to see the command line for both `opt` and `llc` in the expanded command line output, but, I don't see it. What am I missing?
Nothing. Neither opt nor llc are executed by clang. Both of them are
developer-side tools and not intended for "end-user consumption".
clang calls LLVM API directly both for optimization and
codegeneration.
