Really funny... What would you expect the following program to output?
#include <stdio.h>
#include <string.h>
int main (void)
{
int i = 1 , j = -1;
char c = 1, d = 1;
memset(&c, 2, i + j);
memset(&d, 2, i + j);
printf("%d %d\n", c, d);
return 0;
}
On the T2 with gcc (tried a few different versions) it outputs "1 2".
Dunno how to run the sun compiler.
The asm looks reasonable; excerpt:
mov 1, %g1
st %g1, [%fp-8]
mov -1, %g1
st %g1, [%fp-4]
mov 1, %g1
stb %g1, [%fp-9]
mov 1, %g1
stb %g1, [%fp-10]
ld [%fp-8], %g2
ld [%fp-4], %g1
add %g2, %g1, %g1
add %fp, -9, %g2
mov %g2, %o0
mov 2, %o1
mov %g1, %o2
call memset, 0
nop
ld [%fp-8], %g2
ld [%fp-4], %g1
add %g2, %g1, %g1
add %fp, -10, %g2
mov %g2, %o0
mov 2, %o1
mov %g1, %o2
call memset, 0
nop
Notation:
i -> [%fp-8]
j -> [%fp-4]
c -> [%fp-9]
d -> [%fp-10]
Maybe you can try compiling to assembler on the T2 and compiling this
assembler on your blade to see if it gives some clue?
