[Bug middle-end/33181] [4.3 Regression] Revision 127766 miscompiles SPEC CPU 2006
--- Comment #1 from ubizjak at gmail dot com 2007-08-25 10:18 --- From r127766 it is evident that mentioned commit fixed obvious problem that has re-enabled a lot of ifcvt functionality. The bug is in this re-enabled part of ifcvt. But we need a testcase here. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33181
[Bug middle-end/33187] New: Missed cmove opportunity
This testcase:
--cut-here--
double sgn (double __x) {
return __x = 0.0 ? 1.0 : -1.0;
}
--cut here--
shold compile using -m32 -O2 -march=i686 flags into the code using cmove
instruction, but it doesn't due to interference with float-extension of SFmode
constant into DFmode. Gcc figures out that 1.0 can be loaded as SFmode
constant, float-extended to DFmode. The RTL sequence in each arm then looks
like:
--cut here--
(insn 17 16 18 4 cmov.c:2 (set (reg:SF 64)
(mem/u/c/i:SF (symbol_ref/u:SI (*.LC2) [flags 0x2]) [3 S4 A32])) 90
{*
movsf_1} (expr_list:REG_EQUAL (const_double:SF 1.0e+0 [0x0.8p+1])
(nil)))
(insn 18 17 19 4 cmov.c:2 (set (reg:DF 58 [ D.1658 ])
(float_extend:DF (reg:SF 64))) 127 {*extendsfdf2_i387}
(expr_list:REG_DE
AD (reg:SF 64)
(expr_list:REG_EQUAL (const_double:DF 1.0e+0 [0x0.8p+1])
(nil
--cut here--
This effectivelly blocks ifcvt from generating conditional move in this case.
cmov instruction is generated if 1.0 and -1.0 constants are changed to (i.e.)
1.1 and -1.1, in order to disable automatic float-extend functionality:
sgn:
fldl.LC1
fldz
fldl4(%esp)
fucomip %st(1), %st
fstp%st(0)
fldl.LC2
fcmovb %st(1), %st
fstp%st(1)
ret
This is a middle-end bug, as the problem with float-extend should be solved in
ifcvt.c
