; Test the memory layout for all ABI's and byte orders as specified by section
; 4 of MD00305 (MIPS ABIs Described).
; Bitfields are not covered since they are not available as a type in LLVM IR.
;
; The assembly directives deal with endianness so we don't need to account for
; that.

; Deliberately request alignments that are too small for the target so we get
; the minimum alignment instead of the preferred alignment.
