[PATCH] Fix CoerceIntOrPtrToIntOrPtr on big-endian targets

[Jakob Stoklund Olesen]

Hi,

Please review this patch which fixes the CoerceIntOrPtrToIntOrPtr() function on big-endian targets.

If I understand coercion correctly, it is supposed to be equivalent to storing one type and loading a different type from the same address. The CoerceIntOrPtrToIntOrPtr() performs type coercion of integers and pointers without the loads and stores. On big-endian targets, it needs to insert shifts when coercing types of different sizes.

This also gets us the correct argument passing behavior on SPARC v9 which passes small structs in the high bits of registers.

Thanks,
