Proposed patch
It was indeed my fault, sorry. When doing a 32x32->64 multiplication,
CONST_INTs are interpreted in the target mode (DImode). We were forcing
such a CONST_INT into an SImode register without sign-extending it first.
The attached patch seems to fix the testcase. I'm testing on x86_64-linux-gnu.
Could someone with access to PowerPC GNU/Linux or Darwin please test it too?
I could do before-and-after tests for powerpc-eabisim, but it'd probably
take longer.
