Running instruction decoder posttest on an s390 host with an x86 target with allyesconfig shows errors. Instructions used in a couple of kernel objects could not be correctly decoded on big endian system. insn_decoder_test: warning: objdump says 6 bytes, but insn_get_length() says 5 insn_decoder_test: warning: Found an x86 instruction decoder bug, please report this. insn_decoder_test: warning: ffffffff831eb4e1: 62 d1 fd 48 7f 04 24 vmovdqa64 %zmm0,(%r12) insn_decoder_test: warning: objdump says 7 bytes, but insn_get_length() says 6 insn_decoder_test: warning: Found an x86 instruction decoder bug, please report this. insn_decoder_test: warning: ffffffff831eb4e8: 62 51 fd 48 7f 44 24 01 vmovdqa64 %zmm8,0x40(%r12) insn_decoder_test: warning: objdump says 8 bytes, but insn_get_length() says 6 This is because in a few places instruction field bytes are set directly with further usage of "value". To address that introduce and use a insn_set_byte() helper, which correctly updates "value" on big endian systems.
