Hi All,
I'm trying to determine (in target-independent code) what the
*minimum* target alignment of a type is. For example, on darwin,
double's are normally 4-byte aligned, but are 8-byte aligned in some
cases (e.g. when they are the first element of a struct). TYPE_ALIGN
on a double returns 8 bytes, is there any way to find out that they
may end up being aligned to a 4-byte boundary?
#pragma pack or attribute((__aligned__)) can result in arbitrary
misalignments for any type.
