------- Comment #13 from pinskia at gcc dot gnu dot org 2006-11-25 23:26 -------
The only three instructions fwprop touches are done into:
Before:
(insn 112 2 7 2 foo.c:13 (set (reg/f:DI 72)
(plus:DI (reg/f:DI 29 %r29)
(const_int -64 [0xffffffffffffffc0]))) -1 (nil)
(nil))
(insn 7 112 8 2 foo.c:13 (set (mem/f/c/i:DI (reg/f:DI 72) [8 cond+0 S8 A64])
(reg:DI 26 %r26 [ cond ])) 124 {*pa.md:4480} (nil)
(nil))
....
After:
...
(insn 91 89 92 7 foo.c:26 (set (reg/f:DI 26 %r26 [ cond ])
(mem/f/c/i:DI (plus:DI (reg/f:DI 29 %r29)
(const_int -64 [0xffffffffffffffc0])) [8 cond+0 S8 A64])) 124
{*pa.md:4480} (nil)
(nil))
wait. r29 is clobbered by:
(insn 16 15 17 2 foo.c:14 (set (reg/f:DI 29 %r29)
(plus:DI (reg/f:DI 30 %r30)
(const_int -48 [0xffffffffffffffd0]))) 164 {*pa.md:5309} (nil)
(nil))
