| MachineBasicBlock * MSP430TargetLowering::EmitInstrWithCustomInserter | ( | MachineInstr * | MI, |
| MachineBasicBlock * | MBB | ||
| ) | const [override, virtual] |
This method should be implemented by targets that mark instructions with the 'usesCustomInserter' flag. These instructions are special in various ways, which require special support to insert. The specified MachineInstr is created but not inserted into any basic blocks, and this method is called to expand it into a sequence of instructions, potentially also creating new basic blocks and control flow.
Reimplemented from llvm::TargetLowering.

| MVT | VT | ||
| ) | const [override, virtual] |
Given a physical register constraint (e.g. {edx}), return the register number and the register class for the register.
Given a register class constraint, like 'r', if this corresponds directly to an LLVM register class, return a register of 0 and the register class pointer.
This should only be used for C_Register constraints. On error, this returns a register number of 0 and a null register class pointer..

isTruncateFree - Return true if it's free to truncate a value of type Ty1 to type Ty2. e.g. On msp430 it's free to truncate a i16 value in register R15W to i8 by referencing its sub-register R15B.

| bool MSP430TargetLowering::isZExtFree | ( | Type * | Ty1, |

isZExtFree - Return true if any actual instruction that defines a value of type Ty1 implicit zero-extends the value to Ty2 in the result register. This does not necessarily include registers defined in unknown ways, such as incoming arguments, or copies from unknown virtual registers. Also, if isTruncateFree(Ty2, Ty1) is true, this does not necessarily apply to truncate instructions. e.g. on msp430, all instructions that define 8-bit values implicit zero-extend the result out to 16 bits.
