Current code does not check that a register number is in the 0-31 range. Sometimes the parser checks that later for some kinds of instructions, but that leads to unclear / incorrect error messages like that: % cat test.s .text lb $4, 8($32) % llvm-mc test.s -triple=mips64-unknown-linux test.s:2:10: error: expected memory with 16-bit signed offset lb $4, 8($32) ^ Sometimes the parser just crashes: % cat test.s .text lw $4, 8($32) % llvm-mc test.s -triple=mips64-unknown-linux This patch resolves the problem by checking that register number after '$' sign is in the 0-31 range. If the number is out of the range the parser shows the `invalid register number` error, but treats invalid register number as a normal one to continue parsing and catch other possible errors.
