[Bug c/13383] New: ICE in floating point code with optimization on AMD64

[Tasso dot Karkanis at rogers dot com]

The file that I want to attach crashes gcc in a fairly simple-looking functions:

# gcc -c -O2 crash2.i
crash2.c: In function `ag_zero_saddle_ssxd':
crash2.c:3978: internal compiler error: in final_scan_insn, at final.c:2801
Please submit a full bug report,
with preprocessed source if appropriate.

I can't find a way to attach files on this bugzilla page, so I'll attach it
after I enter the bug.

testcase (very fragile)

Here's the reduced testcase.

Confirmed on 3.3-branch, but not on mainline. I don't know if it's a regression, though.

This is most likely not a regression and it only happens on 3.3.
