Since 32-bit instructions with 32-bit input immediate behavior
are used to materialize 16-bit constants in 32-bit registers
for 16-bit instructions, determining the legality based
on the size is incorrect. Change operands to have the size
specified in the type.
Also adds a workaround for a disassembler bug that
produces an immediate MCOperand for an operand that
is supposed to be OPERAND_REGISTER.
The assembler appears to accept out of bounds immediates and
truncates them, but this seems to be an issue for 32-bit
already.
llvm-svn: 289306
Support all instructions with VOP1 encoding with 32 or 64-bit operands for VI subtarget:
VGPR_32 and VReg_64 operand register classes
VS_32 and VS_64 operand register classes with inline and literal constants
Tests for VOP1 instructions.
