Range of element index is too large on MIPS MSA element selection instructions.
The element index range for the following MIPS MSA instructions: sldi, splati, copy_s, copy_u, insert and insve is 1 bit too large. This patch fixes this issue. ChangeLog: gas/testsuite/gas/mips/ * msa.s: Reduced maximum element index range for sldi, splati, copy_s, copy_u, insert and insve instructions. * msa64.s: Likewise. * micromips@msa.d: Likewise. * micromips@msa64.d: Likewise. * msa.d: Likewise. * msa64.d: Likewise. include/opcode/ * mips.h: Updated description of +o, +u, +v and +w for MIPS and microMIPS. opcodes/ * micromips-opc.c (decode_micromips_operand): Reduced range of +o, +u, +v and +w. (micromips_opcodes): Reduced element index range for sldi, splati, copy_s, copy_u, insert and insve instructions. * opcodes/mips-opc.c (decode_mips_operand): Reduced range of +o, +u, +v and +w. (mips_builtin_opcodes): Reduced element index range for sldi, splati, copy_s, copy_u, insert and insve instructions.
