The MachineInstrBuilder
class exposes a function called BuildMI()
. This function is used to build machine instructions.
Machine instructions are created by using the BuildMI
functions, located in the include/llvm/CodeGen/MachineInstrBuilder.h
file. The BuildMI
functions make it easy to build arbitrary machine instructions.
For example, you can use BuildMI
in code snippets for the following purposes:
DestReg = mov 42
(rendered in the x86 assembly as mov DestReg, 42
) instruction:MachineInstr *MI = BuildMI(X86::MOV32ri, 1, DestReg).addImm(42);
MachineBasicBlock &MBB = BuildMI(MBB, X86::MOV32ri, 1, DestReg).addImm(42);
MachineBasicBlock::iterator MBBI = BuildMI(MBB, MBBI, X86::MOV32ri, 1, DestReg).addImm(42)
BuildMI(MBB, X86::JNE, 1).addMBB(&MBB);
