Extended Description

Probably just need a new addPassesToEmitFile() parameter that allows llvm-gcc to informs codegen to optimize for size. There are potentially some minor codegen changes that can save a bit of code size. e.g. X86 backend. Instead of aligning functions on 16-byte boundaries, it can just align on 4-byte boundaries.

Wouldn't adding something to TargetOptions.h be sufficient?

[llvmbot]

Hrm. That seems too easy. Probably will do. :-)
