[llvm-commits] [PATCH] Fix operand ordering for atomicrmw min/max on ARM

[James Molloy]

Hi,

Currently, the code sequences emitted for atomicrmw {umin,umax,min,max}
on ARM are incorrect, because the operands for one of the constituent
instructions are emitted in the wrong order. This causes min to behave
like max and vice versa.

The attached trivial patch fixes this, and adds some better testing to
check for regression.

OK to commit?

Cheers,

James
