Adding -mno-80387 to flags doesn't generate fcomip anymore.
But when I try to compile povray with '-O3 -march=pentium4 -mno-80387
-mfpmath=sse -ffast-math' I got into:
bbox.cpp: In function 'void build_area_table(BBOX_TREE**, long int, long int,
double*)':
bbox.cpp:1753: error: insn does not satisfy its constraints:
(insn 216 200 217 5 (set (reg:CCFP 17 flags)
(compare:CCFP (reg:DF 10 st(2))
(reg/v:DF 9 st(1) [orig:68 bmin$1 ] [68]))) 25 {*cmpfp_i_sse_only}
(nil)
(nil))
bbox.cpp:1753: internal compiler error: in copyprop_hardreg_forward_1, at
regrename.c:1567
