--- Comment #25 from Dimitry Andric <dimitry at andric.com> ---
And indeed, the fontforge-splineutil2-reduced.c testcase still fails with trunk
r278432:

~/obj/llvm-trunk-278432/bin/clang -cc1 -triple i386 -S -target-cpu i686 -O2
-mllvm -verify-machineinstrs=1 fontforge-splineutil2-reduced.c
[...lots of BB dumping...]
*** Bad machine code: Using an undefined physical register ***
- function:    SplineIsLinear
- basic block: BB#6 if.end4.i (0x2c2114cc) [1248B;1488B)
- instruction: 1312B    FNSTSW16r
- operand 1:   %FPSW<imp-use,kill>
fatal error: error in backend: Found 1 machine code errors.

So this problem is definitely not fixed.
