class InlineAsm

Declaration

class InlineAsm : public Value { /* full declaration omitted */ };

Description

LLVM Value Representation This is a very important LLVM class. It is the base class of all values computed by a program that may be used as operands to other values. Value is the super class of other important classes such as Instruction and Function. All Values have a Type. Type is not a subclass of Value. Some values can have a name and they belong to some Module. Setting the name on the Value automatically updates the module's symbol table. Every value has a "use list" that keeps track of which other Values are using this Value. A Value can also have an arbitrary number of ValueHandle objects that watch it and listen to RAUW and Destroy events. See llvm/IR/ValueHandle.h for details.

Methods

¶InlineAsm(const llvm::InlineAsm&)

Declared at: llvm/include/llvm/IR/InlineAsm.h:56

Parameters

const llvm::InlineAsm&

¶int ParseConstraints() const

Declared at: llvm/include/llvm/IR/InlineAsm.h:180

¶static int ParseConstraints(
    llvm::StringRef ConstraintString)

Declared at: llvm/include/llvm/IR/InlineAsm.h:176

Parameters

¶static bool Verify(llvm::FunctionType* Ty,
                   llvm::StringRef Constraints)

Description

Verify - This static method can be used by the parser to check to see if the specified constraint string is legal for the type. This returns true if legal, false if not.

Declared at: llvm/include/llvm/IR/InlineAsm.h:87

Parameters

llvm::FunctionType* Ty

llvm::StringRef Constraints

¶static bool classof(const llvm::Value* V)

Declared at: llvm/include/llvm/IR/InlineAsm.h:185

Parameters

const llvm::Value* V

¶static unsigned int
convertMemFlagWordToMatchingFlagWord(
    unsigned int InputFlag)

Declared at: llvm/include/llvm/IR/InlineAsm.h:320

Parameters

unsigned int InputFlag

¶static llvm::InlineAsm* get(
    llvm::FunctionType* Ty,
