clang clearly performs much much worse than gcc. I would much rather correct results than fast results in the general case.
The compiler should not make this decision for me.
- jcl 18y agoThis is true, but clang is new software under active development. The intention of the project is not to trade off speed for correctness but to eventually be correct and fast. According to the follow-up posts, the differences in rendering may largely be due to bugs in the floating point code generation. Once these are fixed, it is entirely possible that clang could generate the correct images at the higher speed. We won't know until then, however.
