- Subject: SSE types and structures
Lots of open bugreports complains about missaligned accesses in the
structures containing vector types. I guess it is because of:
#define BIGGEST_FIELD_ALIGNMENT (TARGET_64BIT ? 128 : (TARGET_ALIGN_DOUBLE ? 64 : 32))
#define BIGGEST_FIELD_ALIGNMENT 32
But is there any chance to change this for SSE types (set it to 128)
without breaking ABI for structures not containing them?
