Slide 14: PFFT (SSE) seems slow on LDC2: if you can extract a small test case LLVM devs will appreciate a lot a bug report (they fixed many lacks of optimizations submitted by me). If you have a link to the PFFT code them maybe I can do that myself. Slide 25:
Implicit invariants often hard to track down
Then maybe it's a good idea to add such invariants to the dmd front-end code, even before its port to D. Bye, bearophile
