¶virtual bool lowerAsmOperandForConstraint(
    llvm::Value* Val,
    llvm::StringRef Constraint,
    std::vector<MachineOperand>& Ops,
    llvm::MachineIRBuilder& MIRBuilder) const

Description

Lower the specified operand into the Ops vector.\p Val is the IR input value to be lowered\p Constraint is the user supplied constraint string\p Ops is the vector to be filled with the lowered operands

Declared at: llvm/include/llvm/CodeGen/GlobalISel/InlineAsmLowering.h:47

Parameters

llvm::Value* Val

llvm::StringRef Constraint

std::vector<MachineOperand>& Ops

llvm::MachineIRBuilder& MIRBuilder

Returns

True if the lowering succeeds, false otherwise.

¶bool lowerInlineAsm(
    llvm::MachineIRBuilder& MIRBuilder,
    const llvm::CallBase& CB,
    std::function<ArrayRef<Register>(
        const Value&)> GetOrCreateVRegs) const

Description

Lower the given inline asm call instruction\p GetOrCreateVRegs is a callback to materialize a register for the input and output operands of the inline asm

Declared at: llvm/include/llvm/CodeGen/GlobalISel/InlineAsmLowering.h:38

Parameters

llvm::MachineIRBuilder& MIRBuilder

const llvm::CallBase& CB

std::function<ArrayRef<Register>(const Value&)> GetOrCreateVRegs

Returns

True if the lowering succeeds, false otherwise.
