FYI, the CMOVNTQ's are not gone at all

And Pentium 4 always had the biggest performance problems, why don't you just get an 80386, 8086, or 4004 not causing such trouble ???

Useless bloat ...

And what mtune disables such absurdity ???

There is no "Crappy code", just the exclam's

You love such unrelated side notes

I'm sure GCC optimization experts will be able to explain me:

- What's the goal of REP RET

- What's the goal of O16 NOP

- What's the goal of avoiding PUSH and POP and using MOV [ESP+blah] instead

- How bloat (redundant repeated encoding of "boring" or same numbers as 32-bit values) improves performance

- Why preserve EBP when you don't need it at all
