[llvm-dev] difference between llvm-gcc and clang

[Yuxi Chen via llvm-dev]

Hi everyone,

Both llvm-gcc and clang would use llvm as its backend. Dose everyone know the difference of bitcode generated by llvm-gcc and llvm? Or actually they are same, like if I use the same compiler options, like -O4.

Any help is appreciated.

Best,
Yuxi
