Old Synopsis: Pentium4 + SSE: register to spill in class 'FLOAT_REGS' [minimal example]
New Synopsis: ICE in spill_failure, at reload1.c:1916 with SSE
State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Wed Dec 4 14:05:13 2002
State-Changed-Why:
Confirmed. With 3.2.2pre I get
tmp/g> /home/bangerth/bin/gcc-3.2.2-pre/bin/gcc -march=pentium4 -O -mfpmath=sse -c x.c
x.c: In function `main':
x.c:17: unable to find a register to spill in class `FLOAT_REGS'
x.c:17: this is the insn:
(insn 52 50 53 (set (subreg:SF (reg/v:DI 22 rxmm1 [67]) 0)
(float:SF (reg:DI 0 rax [73]))) 170 {*floatdisf2_i387_only} (nil)
(nil))
x.c:17: confused by earlier errors, bailing out
3.3pre gives a slightly different message, but dies as well:
tmp/g> /home/bangerth/bin/gcc-3.3-pre/bin/gcc -march=pentium4 -O -mfpmath=sse -c x.c
x.c: In function `main':
x.c:17: error: unable to find a register to spill in class `FLOAT_REGS'
x.c:17: error: this is the insn:

(float:SF (reg:DI 0 rax [73]))) 126 {*floatdisf2_i387_only} (nil)
(nil))
x.c:17: internal compiler error: in spill_failure, at reload1.c:1916
