This patch adds support for a new CGEN_OPEN_INSN_ENDIAN argument for @arch@_cgen_cpu_open. This is useful for architectures in which the endianness of the instruction words is not the same than the endianness used for data. An accompanying patch has been sent to the CGEN mailing list that adds support for this argument on the CGEN side [1]. Its been already pre-approved [2], and will be applied simultaneously with this binutils series. [1] https://sourceware.org/pipermail/cgen/2020q2/002733.html [2] https://sourceware.org/pipermail/cgen/2020q2/002737.html include/ChangeLog: 2020-06-04 Jose E.
