--- Comment #15 from Richard Biener <rguenth at gcc dot gnu.org> ---
Btw, unpatched and with a cross to sparc-linux (didn't figure out a working
solaris triplet that builds) and
unsigned int foo (unsigned short *x)
{
return x[0] << 16 | x[1];
}
I see
32 bit load in host endianness found at: _8 = (int) load_dst_11;
foo (short unsigned int * x)
{
short unsigned int _3;
int _4;
int _5;
short unsigned int _6;
int _7;
int _8;
unsigned int _9;
short unsigned int * load_src_10;
unsigned int load_dst_11;
<bb 2>:
_3 = *x_2(D);
_4 = (int) _3;
_5 = _4 << 16;
_6 = MEM[(short unsigned int *)x_2(D) + 2B];
_7 = (int) _6;
load_src_10 = x_2(D);
load_dst_11 = MEM[(short unsigned int *)load_src_10];
_8 = (int) load_dst_11;
_9 = (unsigned int) _8;
return _9;
expanding from
<bb 2>:
load_dst_11 = MEM[(short unsigned int *)x_2(D)];
return load_dst_11;
gets you
foo:
lduh [%o0], %g1
lduh [%o0+2], %o0
sll %g1, 16, %g1
jmp %o7+8
or %o0, %g1, %o0
which looks perfect to me.
So it must be sth else that breaks the libjava case?
Can someone please provide preprocessed source for jcf-parse.c and
point out the error in the assembly at least?
