The minimal testcase is this:
--------------------
extern double log1p (double __x);
double test () {
return log1p(1.0);
}
--------------------
g/x> /home/bangerth/bin/gcc-4.0-pre/bin/c++ -ffast-math -c x.i
x.i: In function ?double test()?:
x.i:4: error: unrecognizable insn:
(insn 9 8 10 0 (set (reg:XF 64)
(float_extend:XF (reg:XF 62))) -1 (nil)
(expr_list:REG_DEAD (reg:XF 62)
(nil)))
x.i:4: internal compiler error: in extract_insn, at recog.c:2020
Please submit a full bug report,
with preprocessed source if appropriate.
The same testcase ICEs with the C++ compiler, btw.
