hasStringifyOrCharifyBefore()

bool clang::VAOptExpansionContext::hasStringifyOrCharifyBefore ( ) const

Definition at line 202 of file VariadicMacroSupport.h.

References hasCharifyBefore().

isInVAOpt()

bool clang::VAOptDefinitionContext::isInVAOpt ( ) const

inline

Returns true if we have seen the VA_OPT and '(' but before having seen the matching ')'.

Definition at line 83 of file VariadicMacroSupport.h.

isVAOptToken()

bool clang::VAOptDefinitionContext::isVAOptToken ( const Token &  T ) const

inline

Definition at line 77 of file VariadicMacroSupport.h.

reset()

void clang::VAOptExpansionContext::reset ( )

inline

Definition at line 159 of file VariadicMacroSupport.h.

sawClosingParen()

bool clang::VAOptDefinitionContext::sawClosingParen ( )

inline

Call this function each time an rparen is seen.

It returns true only if the rparen that was just seen was the eventual (non-nested) closing paren for VAOPT, and ejects us out of the VAOPT context.

Definition at line 100 of file VariadicMacroSupport.h.

sawHashOrHashAtBefore()

void clang::VAOptExpansionContext::sawHashOrHashAtBefore ( const bool  HasLeadingSpace, const bool  IsHashAt  )

inline

Definition at line 171 of file VariadicMacroSupport.h.

sawOpeningParen()

void clang::VAOptDefinitionContext::sawOpeningParen ( SourceLocation  LParenLoc )

inline

Call this function each time an lparen is seen.

Definition at line 107 of file VariadicMacroSupport.h.

sawVAOptFollowedByOpeningParens()

void clang::VAOptExpansionContext::sawVAOptFollowedByOpeningParens ( const SourceLocation  VAOptLoc, const unsigned int  NumPriorTokens  )
