Hello,
On OpenSolaris amd64 I'm seeing the following build failure:
CC i386-softmmu/op_helper.o

gmake[1]: *** [op_helper.o] Error 1
make: *** [subdir-i386-softmmu] Error 2
Looks like an issue with make_floatx80(). Any ideas?
Thanks,

As suggested by Peter, I inspected the op_helper.c preprocessor output:
# 108 "/export/home/andreas/QEMU/qemu/target-i386/op_helper.c"
static const CPU86_LDouble f15rk[7] =
{
((floatx80) { 0x0000000000000000LL, 0x0000 }),
((floatx80) { 0x8000000000000000LL, 0x3fff }),
((floatx80) { 0xc90fdaa22168c235LL, 0x4000 }),
((floatx80) { 0x9a209a84fbcff799LL, 0x3ffd }),
((floatx80) { 0xb17217f7d1cf79acLL, 0x3ffe }),
((floatx80) { 0xb8aa3b295c17f0bcLL, 0x3fff }),
((floatx80) { 0xd49a784bcd1b8afeLL, 0x4000 }),
};
Doesn't look unexpected.
typedef floatx80 CPU86_LDouble;
and
# 153 "/export/home/andreas/QEMU/qemu/fpu/softfloat.h"
typedef struct {
uint64_t low;
uint16_t high;
} floatx80;
look okay, too.

Same with gcc 4.3.2:
$ gcc-4.3.2 --version
gcc-4.3.2 (GCC) 4.3.2

This one is on OpenSolaris 2010.05 snv_134b (previously on 2009.06
snv_111b).

I have to say I don't really say why it doesn't compile. Do you have
problems at other places, where a single floatx80 constant is
initialized?
My next series remove this table, and uses directly the constants name
in helper_fld*_ST0(), so it may fix that issue.
