Synopsis: 3.1 segfault in copyprop_hardreg_forward_1 on sparc-sun-solaris2.8
State-Changed-From-To: open->analyzed
State-Changed-By: jakub
State-Changed-When: Tue Apr 30 02:12:05 2002
State-Changed-Why:
Weird. I get on the same code using the same options
following ICE instead:
nucleic.c: In function `___H__20_nucleic':
nucleic.c:21747: insn does not satisfy its constraints:
(insn 25599 25597 25601 (set (reg:SF 72 %f40 [127])
(mem:SF (plus:SI (reg/v:SI 18 %l2 [116])
(const_int 19 [0x13])) [0 S4 A64])) 85 {*movsf_insn_novis} (nil)
(nil))
nucleic.c:21747: Internal compiler error in final_scan_insn, at final.c:2551
Please submit a full bug report,
with preprocessed source if appropriate.

Working on a fix, assuming the unrecognized insn cprop
crashes on for you is the same one as is caught by final.c
for me.
