Machine : alpha
>Description:
Compiling some ports generate an internal compiler error.
These ports have incommin that they ocerride the standard -O2
with a -O. (one example is print/psutils).
the offending file fails with:
epsffit.c:43: warning: return type of `main' is not `int'
epsffit.c: In function `main':
epsffit.c:189: error: push_frame_in_operand
(insn 264 263 265 28 0x168195918 (set (reg:DI 18 $18)
(reg/f:DI 63 FP)) 228 {*movdi_er_nofix} (nil)
(nil))
epsffit.c:189: internal compiler error: in push_frame_in_operand, at
protector.c:2565
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Reducing the offendig file to its bare minimum while still
producing errors (see How-To-Repeat) makes cc error out with:
test.c: In function `main':
test.c:13: error: push_frame_in_operand
(insn 16 15 17 0 0x1616baf20 (set (reg:DI 18 $18)
(reg/f:DI 63 FP)) 228 {*movdi_er_nofix} (nil)
(nil))
test.c:13: internal compiler error: in push_frame_in_operand, at
protector.c:2565
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
>How-To-Repeat:
$ #either do
$ cd /usr/ports/print/psutils
$ make
$ #or to see the effect from a minimal c file:
$ cat > test.c <<EOF
/* minimal example file producing the error */
#include <stdio.h>
int
main(int argc, char **argv)
{
char buf[128];
float a, b;
sscanf(buf, "%f %f", &a, &b);
return 0;
}
EOF
$ cc -O test.c
test.c: In function `main':
test.c:13: error: push_frame_in_operand
(insn 16 15 17 0 0x1616baf20 (set (reg:DI 18 $18)
(reg/f:DI 63 FP)) 228 {*movdi_er_nofix} (nil)
(nil))

>Fix:
Unknown.
Actually compiling with -O2 does not cause this errror.
