Konstantin Schwarz 1a3e89aa2b [MIR] Add comments to INLINEASM immediate flag MachineOperands
Summary:
The INLINEASM MIR instructions use immediate operands to encode the values of some operands.
The MachineInstr pretty printer function already handles those operands and prints human readable annotations instead of the immediates. This patch adds similar annotations to the output of the MIRPrinter, however uses the new MIROperandComment feature.
