- CoolGuySteve 6y agoStatic analysis is a lot slower but regular clang++ is also significantly slower than g++, like a 4-5 minute build time vs 2:30 on g++. It might have something to do with a heavy usage of templates in a few files, I don't know. Clang's autovectorization is better in a few functions I disassembled but otherwise the generated code doesn't benchmark any faster, it's better in some places, worse in others.
