Indeed.
Please, ooPo, could you check binutils, file opcodes/mips-opc.c, seek to the line 760 | Code: | | {"mfpc", "t,P", 0x4000c801, 0xffe0ffc1, LCD|WR_t|RD_C0, M1|N5 }, |
and replace "M1|N5" by "M1|N5|T5" please ? Thanks ;)

Actually, insert a new line after that mfpc line and use:
| Code: | | {"mfpc", "t,P", 0x4000c801, 0xffe0ffc1, RD_C0|WR_t, T5 }, |
The LCD flag is incorrect for r5900 so there needs to be a seperate line for mfpc.
