Never mind, I messed up the patch

I tried this patch on my MIPS toolchain build but GCC is still f
The block frequencies are very small in this case leading to rounding
errors when computing the edge frequency. The rounding error was then
propagated into the recomputed probabilities, leading to insanities in
the outgoing edge probabilities on the jump threading path. Eventually

You can open a bug report and attach the preprocessed file there.
Thank
I got the preprocessed source. With the aarch64 cross-compiler I built
I am able to reproduce the ICE. Looking at it now.
