◆ lowerFormalArguments()
|
overridevirtual |
This hook must be implemented to lower the incoming (formal) arguments, described by Args, for GlobalISel.
Each argument must end up in the related virtual register described by VRegs. In other words, the first argument should end up in VRegs[0], the second in VRegs[1], and so on. MIRBuilder is set to the proper insertion for the argument lowering.
- Returns
- True if the lowering succeeded, false otherwise.
Reimplemented from llvm::CallLowering.
