Build Optimization

[mata...@gmail.com]

Hi,

Are there any optimization flags for llgo command?

It seems to recognize -O1 -O2 -O3 flags.
Is there a formal documentation for that?

Thanks!

Yes, these are all recognised, as well as -O0 (no optimisation), and -Os (optimise for space).

There's no llgo-specific documentation. These flags simply select the relevant LLVM codegen optimisation level (none, less, default, aggressive). I'm not sure if/where the levels are documented in LLVM.

Cheers,

Andrew

 

Thanks!
