Methods

¶AAValueSimplify(const llvm::IRPosition& IRP)

Declared at: llvm/include/llvm/Transforms/IPO/Attributor.h:2359

Parameters

const llvm::IRPosition& IRP

¶static llvm::AAValueSimplify& createForPosition(
    const llvm::IRPosition& IRP,
    llvm::Attributor& A)

Description

Create an abstract attribute view for the position \p IRP.

Declared at: llvm/include/llvm/Transforms/IPO/Attributor.h:2370

Parameters

const llvm::IRPosition& IRP

llvm::Attributor& A

¶virtual Optional<llvm::Value*>
getAssumedSimplifiedValue(
    llvm::Attributor& A) const

Description

Return an assumed simplified value if a single candidate is found. If there cannot be one, return original value. If it is not clear yet, return the Optional::NoneType.

Declared at: llvm/include/llvm/Transforms/IPO/Attributor.h:2367

Parameters

llvm::Attributor& A

¶const llvm::IRPosition& getIRPosition() const

Description

Return an IR position, see struct IRPosition.
