Hi,
I found a quick way to fix it by substituting in utils.h your
load/store_32 functions:
inline static
u32 load_carmine32(const u32 *addr) {
u32 tmp;
u32 ret;
__asm__ __volatile__("lwbrx %0,0,%1;\n" : "=r" (tmp) : "r" (addr),
"m" (*addr));
__asm__ __volatile__("rotrwi %0,%1,8;\n" : "=r" (ret): "r" (tmp));
return ret;
}
inline static
void store_carmine32( u32 *addr, u32 argb) {
u32 tmp;
__asm__ __volatile__("rotlwi %0,%1,8;\n" : "=r" (tmp): "r" (argb));
__asm__ __volatile__("stwbrx %1,0,%2;\n" : "=m" (*addr) : "r" (tmp),
"r" (addr));
}
Maybe it could be optimized a little more in terms of used registers,
but it works well.
I had to fix also JPEG/PNG image loading, since I'm basically working ARGB.
Thanks a lot!
Matteo
