[llvm-dev] Performance comparison of Clang/LLVM vs. GCC

[Haidl, Michael via llvm-dev]

Hi everyone,

I am currently writing my PhD thesis about my LLVM-based research topic 
called PACXX. I would like to add some performance data of LLVM vs. GCC 
regarding compilation time and overall code generation quality. Are 
there resources available that shows the latest performance numbers of 
LLVM 4.0 vs GCC? I remember a talk at EuroLLVM17 saying that LLVM is 
(almost) on par with GCC.

Btw. I am planing to open source my research project in the coming month 
and wanted to ask, if their is interest in the LLVM community that an 
SPMD programming model integrated into C++ (like C++AMP or SYCL) is 
going upstream and what is required to upstream parts of my code base.

Cheers,
