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