Disabling cmov for x86_64

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

How do I disable cmov code generation for x86_64 completely in GCC 4.9.x?

Changing the #define in i386.c - stops it in most places. It still
slips thru - is there a definitive way to stop emitting 64-bit code
with cmov ?

Thanks in advance
Regards
