a test case
Fortunately I could get a testcase with building cernlib-2006 for x86.
For the attached testcase, 4.3.1 sh4-linux f951 fails:
error: unrecognizable insn:
(insn 10204 7670 6894 605 ../../../src/geant321/ggeom/gnext.F:774 (parallel [
(set (reg:SF 150 fpul)
(const_double:SF 1.0e+10 [0x0.9502f9p+34]))
(clobber (reg:SI 0 r0))
]) -1 (nil))
with -O2 -fno-automatic -mieee.
I've also confirmed that it doesn't fail with 4.4.0 and 4.2.4
f951 and the patch suggested in #4 gets rid of the failure on
4.3-branch. I'd like to backport it to 4.3 if the usual tests
are ok on the branch.
