P1144?

Try clang trunk :) it fully unrolled your C++ code :D

This is quite interesting. So we can generate gimple (like gcc IR?) and load it to gcc, to optimize it and generate binary? like LLVM IR we can optimize using opt, compile to asm with llc, etc..

​

Any examples/tutorials?

And try Clang even with -stdlib=libc++. Quite amazing numbers.

This will probably miss GCC 9.. no activity on the gcc / libstdc++ mailing list..

maybe you can also do same comparision for Chromium?

pyler2 4 points · Dec 2018

but the question is who should write a Rust GCC frontend? :D Mozilla? Too much effort..

Have Mozilla investigated a Facebook's BOLT tool to optimalize PGO binary builds even more?
