Alexey Dobriyan 890890cb8e x86/i386: Use less assembly in strlen(), speed things up a bit ... Current i386 strlen() hardcodes NOT/DEC sequence. DEC is mentioned to be suboptimal on Core2. So, put only REPNE SCASB sequence in assembly, compiler can do the rest. The difference in generated code is like below (MCORE2=y): <strlen>: push %edi mov $0xffffffff,%ecx mov %eax,%edi xor %eax,%eax repnz scas %es:(%edi),%al not %ecx - dec %ecx - mov %ecx,%eax + lea -0x1(%ecx),%eax pop %edi ret Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Jan Beulich <JBeulich@suse.com> Link: http://lkml.kernel.org/r/20111211181319.GA17097@p183.telecom.by Signed-off-by: Ingo Molnar <mingo@elte.hu>		2011-12-12 18:33:42 +01:00
