X86: validate 'int' instruction The int instruction takes as an operand an 8-bit immediate value. Validate that the input is valid rather than silently truncating the value. llvm-svn: 225941

[X86] Remove special validation for INT immediate operand from AsmParser. Instead mark its operand type as u8imm which will cause it to fail to match. This is more consistent with other instruction behavior. This also fixes a bug where negative immediates below -128 were not being reported as errors. llvm-svn: 249989

[X86] Change the immediate for IN/OUT instructions to u8imm so the assembly parser will check the size. llvm-svn: 250012
