Hi Evan,
Can you get me a test case? I need to see what gcc is doing. Thanks,
Sure. Zero sized fields in structs may not be very useful, but it is
still legal to use them, in particular you can take their address,
like this:
struct Z {};
struct Y {
int i;
struct Z z;
};

I'm running into this problem as well -- it crashing while compiling
gcov.c on my PPC G4.
While r46381 seems the obvious culprit, to tell the truth I didn't check
whether reverting this patch fixes the problem - so I could be wrong.
Ciao,
Duncan.

It's likely
to also permute the PROJ_* and LLVM_* includes, but I don't think that

Is there any reason to actually make a machineinstr here? It seems
like it would be possible to just emit nop to the .s file. The JIT
doesn't need this.
I initially had that, but I thought that it would be better to do
