compiling code like:
int foo(int a, int b)
{
if (a > b)
return a;
else
return b;
}
with:
or1k-elf-gcc -O2 -mcmov -c -S cmov.c -o -
caused an internal compiler error
due to the fact that or1k_compare_op0 and or1k_compare_op1
never get assigned with anything
---
Note!
I'm not at all confident about this...
Feedback or better suggestions are appreciated.
