1902 * rtlanal.c (subreg_get_info): Use more local variables.
1903 Remark that for HARD_REGNO_NREGS_HAS_PADDING, each scalar unit
1904 occupies at least one register. Assume that full hard registers
1905 have consistent endianness. Share previously-duplicated if block.
1906 Rework the main handling so that it operates on independently-
1907 addressable YMODE-sized blocks. Use subreg_size_lowpart_offset
1908 to check lowpart offsets, without trying to find an equivalent
1909 integer mode first. Handle WORDS_BIG_ENDIAN != REG_WORDS_BIG_ENDIAN
1910 as a final register-endianness correction.
