--- Comment #1 from David Binderman <dcb314 at hotmail dot com> ---
Reduced C code seems to be:
putRGBAAseparate8bittile_w(int *cp, unsigned char *g) {
char *a, *r;
unsigned *b;
int _x;
for (; _x; _x -= 8) {
*cp++ = *r++ | (unsigned)*g++ << 8 | *b++ << 16 | (unsigned)*a++ << 24;
*cp++ = *r++ | (unsigned)*g++ << 8 | *b++ << 16 | (unsigned)*a++ << 24;
}
}
This bug seems strongly related to gcc bugzilla # 86179, which was
# 446 on my list of 724.
