Constructor & Destructor Documentation

◆ AsmToken() [1/3]

llvm::AsmToken::AsmToken ( )
default

◆ AsmToken() [2/3]

llvm::AsmToken::AsmToken ( TokenKind  Kind,
StringRef  Str,
APInt  IntVal 
)
inline

Definition at line 82 of file MCAsmLexer.h.

◆ AsmToken() [3/3]

llvm::AsmToken::AsmToken ( TokenKind  Kind,
StringRef  Str,
int64_t  IntVal = 0 
)

Member Function Documentation

◆ getAPIntVal()

APInt llvm::AsmToken::getAPIntVal ( ) const
inline

Definition at line 126 of file MCAsmLexer.h.

References assert(), BigNum, and Integer.

◆ getEndLoc()

SMLoc AsmToken::getEndLoc ( ) const

◆ getIdentifier()

StringRef llvm::AsmToken::getIdentifier ( ) const
inline

Get the identifier string for the current token, which should be an identifier or a string.

This gets the portion of the string which should be used as the identifier, e.g., it does not include the quotes on strings.

Definition at line 105 of file MCAsmLexer.h.

◆ getIntVal()

int64_t llvm::AsmToken::getIntVal ( ) const
inline

◆ getKind()

TokenKind llvm::AsmToken::getKind ( ) const
inline

◆ getLoc()

SMLoc AsmToken::getLoc ( ) const

◆ getLocRange()

SMRange AsmToken::getLocRange ( ) const

Definition at line 34 of file MCAsmLexer.cpp.

References llvm::MCAsmLexer::getLoc().

Referenced by isNot(), and RefineErrorLoc().

◆ getString()

StringRef llvm::AsmToken::getString ( ) const
inline

Get the string for the current token, this includes all characters (for example, the quotes on strings) in the token.

The returned StringRef points into the source manager's memory buffer, and is safe to store across calls to Lex().

◆ getStringContents()

StringRef llvm::AsmToken::getStringContents ( ) const
inline

Get the contents of a string token (without quotes).

Definition at line 96 of file MCAsmLexer.h.

References assert(), llvm::StringRef::size(), llvm::StringRef::slice(), and String.

Referenced by getIdentifier(), llvm::IsCPSRDead< MCInst >(), and isValidEncoding().
