I am not familiar with it, so I'd appreciate if you could summarise its advantages and disadvantages. What I found by my own search: clang's machine code generation is faster than gcc's. However: Does that also result in faster programs, or just in less build time? Thanks to ccache, the time to build Sage doesn't matter so much to me any longer. But I do care about the speed of the resulting programs. Here are reports that with clang things won't work in different ways (e.g., IIUC, segfaults in linbox on openSuse). Does that mean clang is buggy resp. not mature enough, or does that mean clang uncovers real bugs that are silently ignored by gcc? And if I want to give it a try: Currently I have a SageMath installation compiled with gcc. Does it suffice to "make clean" before starting re-installation of SageMath with clang? Or "make distclean"? Best regards, Simon -- You received this message because you are subscribed to the Google Groups "sage-release" group.
