References hasCharifyBefore().

◆ isInVAOpt()

bool clang::VAOptDefinitionContext::isInVAOpt
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
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.

const bool  IsHashAt

◆ sawOpeningParen()

void clang::VAOptDefinitionContext::sawOpeningParen
inline

Call this function each time an lparen is seen.

Definition at line 107 of file VariadicMacroSupport.h.

◆ sawVAOptFollowedByOpeningParens()
