(In reply to Jakub Jelinek from comment #2)
This is weird, I've tried to bisect it, r197678 still compiled it without
hanging, r197681 ICEd somewhere in lra-constraints.c, but if I rebuild
lra-constraints.o with -O0, it instead ICEs on frame reg uses during
final_scan_insns (i.e. LRA hasn't replaced the frame pointer with hard frame
pointer or stack pointer), r197696 still ICEs, r197700 hangs.
BTW, doing -da before it hangs, I'm seeing right in *.split4 dump REG_EQUIV
notes like:
(insn 20109 70 20110 19 (set (reg/f:DI 38 r9 [19927])
(plus:DI (reg/f:DI 7 sp)
(const_int 16 [0x10]))) 254 {*leadi}
(expr_list:REG_EQUIV (plus:DI (reg/f:DI 20 frame)
(const_int -8 [0xfff8]))
(nil)))
wonder if it isn't a bug that RA hasn't replaced the eliminable register in
the note with sp (or hfp).

[Bug rtl-optimization/25848] New: missed-rtl-optimization
This C example:
int f1(int a)
{
int b = a*2;
return b+a;
}
---
Currently we produce:
_f1:
mr 0,3
slwi 3,3,1
add 3,3,0
extsw 3,0
blr
-
We should be able to produce:
_f1:
mr 0,3
slwi 3,3,1
add 3,0,3
blr
,so the extsw instruction should go out.
