Hello,
That and many other combinations fix the issue. Including changing the code
around the inline asm, or using different optimizations.
What seems wrong is that gcc uses the same register for 2 outputs.

Actually I think the inline-asm should be:
#define CMOV_COMBO( val1, val2 ) \
asm volatile ( \
cmpl %0, %3\n\t \
cmovl %3, %0\n\t \
