- saagarjha 7y agoAnd here are plenty that support the converse ;) I don't think there's anything that points to one being definitively better than the other in performance.

- StreamBright 7y agoLike the one where they turned off null checks? https://joelaro.wordpress.com/2015/09/30/gcc-optimization-fdelete-null-pointer-checks/ https://joelaro.wordpress.com/2015/09/30/gcc-optimization-fd...
- saagarjha 7y agoClang has this too.
- StreamBright 7y agoNot as much as GCC. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90949 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90949
- saagarjha 7y agoThat’s a bug, not an optimization.
- wumpus 7y agoEvery performant compiler on the SPECcpu benchmarks does this.
