13; Test the memory layout for all ABI's and byte orders as specified by section
14; 4 of MD00305 (MIPS ABIs Described).
15; Bitfields are not covered since they are not available as a type in LLVM IR.
16;
17; The assembly directives deal with endianness so we don't need to account for
18; that.
19
20; Deliberately request alignments that are too small for the target so we get
21; the minimum alignment instead of the preferred alignment.
