CRC checksum is not a cryptographic hash function. It is easy to add a few bytes of garbage at the end of a file so that the CRC of the entire file becomes a desired value. But did you need to do that in the linker? Yes. github.com/rui314/mold/bl…

With Lisa's keynote over, I will casually drop this to confirm that y-cruncher v0.8.5 will get #Zen5 optimizations with it's big and fat #AVX512. Release date still ETA - pending final silicon. x.com/Mysticial/stat… ST and BBP will be where the light shines the brightest.

@dyaroshev @geofflangdale @HaroldAptroot @FUZxxl FWIW, I've also given it a decent write-up at corsix.org/content/abusin…. Only notable change is putting maskz on the shuffle rather than on the permutexvar, as uops.info suggests maskz costs a few cycles, so might as well put it on the cheaper of the two instructions.

Example of why power draw is a poor proxy for how well a program is utilizing your hardware (i7-7700K CPU in this case). In one case, execution port use is heavy and IPC is high, so the CPU's pipeline is running at high utilization. However power draw is low. Second case...
