Option -mfloat-gprs=yes works fine with basic operations on floats like +, -, /
*.
The following simple example produces an internal compiler error:
# 1 "test.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "test.c"
int compare(float x, float y)
{
return (x < y);
}
The error message is
test.c: In function `compare':
test.c:5: error: unrecognizable insn:
(insn 14 13 15 0 (set (reg:CCFP 122)
(compare:CCFP (reg:SF 120 [ x ])
(reg:SF 121 [ y ]))) -1 (nil)
(expr_list:REG_DEAD (reg:SF 120 [ x ])
(expr_list:REG_DEAD (reg:SF 121 [ y ])
(nil))))
test.c:5: internal compiler error: in extract_insn, at recog.c:2083
Please submit a full bug report,
with preprocessed source if appropriate.
The compile command is
powerpc-eabispe-gcc -bpowerpc-eabispe -mcpu=505 -mno-sdata -mfloat-gprs=yes
-Wall -Wstrict-prototypes -Wall -save-temps -c -o o/test.o test.c

------- Comment #2 from rguenth at gcc dot gnu dot org 2006-11-13 14:51 -------
GCC 3.4.x is out of maintainance, can you try with at least 4.0.3 or 4.1.1?
Thanks.

------- Comment #3 from poellmann at nm dot hsd dot utc dot com 2006-11-14 10:10 -------
The problem maintains with gcc 4.1.1. The error-message is slightly different:
test.c: In function 'compare':
test.c:5: error: unrecognizable insn:
(insn 12 11 13 1 (set (reg:CCFP 123)
(compare:CCFP (reg:SF 121)
(reg:SF 122))) -1 (nil)
(nil))

First -mcpu=505 is incorrect for the e500 series, the PPC505 is different from
the 8540 which is the e500 series. So this is just a matter of having bad
options as far as I can tell.
Confirmed.
