| ### How to debug GCC LTO | ||
| Run do the command with `-v -save-temps` and then extract the `lto1` line from the output and run that under the debugger |

Would it make sense to wire up -Csave-temps to GCC's -save-temps option?

I don't remember what's the output of GCC's -save-temps. Does cg_llvm output LLVM-specific stuff (except some stuff done manually like the bitcode used for LTO)?

LLVM doesn't produce intermediate files afaik. It keeps everything in memory until rustc explicitly tells it to either write bitcode or an object files.
