Why does GCC produce faster code using "-march=pentium2 -mtune=pentium4" on a Pentium 4 chip versus plain -march=pentium4? Try it... CPUTYPE=pentium2 CFLAGS+= -mtune=pentium4 COPTFLAGS+= -mtune=pentium4 -- BSD Podcasts @ http://bsdtalk.blogspot.com/

...anks Eric, After the original reply to my query I had a good look at the GCC documentation for these options, and what I discovered is that “there is no consensus” in GCC. Basically, saying do what GCC does was a non-answer as it clarified nothing. X86 has deprecated ‘-mcpu’ in favour of ‘-mtune’, and it uses ‘-mtune’ to mean that the scheduling, etc. should be biased in favour of more performant code for the processor identified by ‘-mtune’, but that the code is still 100% functional on all other processors in the family identified by ‘-march’. MIPS and ARM seem to have a very differe...

...time to carefully explain this to me. So if I am the author of the backend for a new processor technology, or willing to modernise my existing implementation, you would recommend that the ‘-mcpu’ option is deprecated and probably best not used at all, or perhaps just as a synonym for ‘-march + -mtune’? The first part of the target triple guides the overall high level processor architecture - essentially the CPU - and that I would be better using ‘-march’ to specify the variants of this CPU architecture for groups of variants that are not binary compatible with each other; effectively my ISA...
