Detailed Description

Engages in a tight little dance with the lexer to efficiently preprocess tokens.

Lexers know only about tokens within a single source file, and don't know anything about preprocessor-level issues like the #include stack, token expansion, etc.

void clang::Preprocessor::AnnotateCachedTokens ( const Token & Tok )

We notify the Preprocessor that if it is caching tokens (because backtrack is enabled) it should replace the most recent cached tokens with the given annotation token.

This function has no effect if backtracking is not enabled.

Note that the use of this function is just for optimization, so that the cached tokens doesn't get re-parsed and re-resolved after a backtrack is invoked.

void Preprocessor::EnableBacktrackAtThisPos ( )

From the point that this method is called, and until CommitBacktrackedTokens() or Backtrack() is called, the Preprocessor keeps track of the lexed tokens so that a subsequent Backtrack() call will make the Preprocessor re-lex the same tokens.

Nested backtracks are allowed, meaning that EnableBacktrackAtThisPos can be called multiple times and CommitBacktrackedTokens/Backtrack calls will be combined with the EnableBacktrackAtThisPos calls in reverse order.

NOTE: DO NOT forget to call either CommitBacktrackedTokens or Backtrack at some point after EnableBacktrackAtThisPos. If you don't, caching of tokens will continue indefinitely.

We want to produce a diagnostic at location IncLoc concerning an unreachable effect at location MLoc (eg, where a desired entity was declared or defined).

Determine whether the right way to make MLoc reachable is by #include, and if so, what header should be included.

This is not necessarily fast, and might load unexpected module maps, so should only be called by code that intends to produce an error.

Parameters

IncLoc	The location at which the missing effect was detected.
MLoc	A location within an unimported module at which the desired effect occurred.

Returns: A file that can be #included to provide the desired effect. Null if no such file could be determined or if a #include is not appropriate (eg, if a module should be imported instead).

◆ getImmediateMacroName()

StringRef clang::Preprocessor::getImmediateMacroName ( SourceLocation Loc )

inline

Retrieve the name of the immediate macro expansion.

This routine starts from a source location, and finds the name of the macro responsible for its immediate expansion. It looks through any intervening macro argument expansions to compute this. It returns a StringRef that refers to the SourceManager-owned buffer of the source where that macro name is spelled. Thus, the result shouldn't out-live the SourceManager.

This routine can be used to produce a source location that points just past the end of the token referenced by Loc, and is generally used when a diagnostic needs to point just after a token where it expected something different that it received. If the returned source location would not be meaningful (e.g., if it points into a macro), this routine returns an invalid source location.

Parameters

Offset an offset from the end of the token, where the source location should refer to. The default offset (0) produces a source location pointing just past the end of the token; an offset of 1 produces a source location pointing to the last character in the token, etc.

◆ SetCodeCompletionPoint()

bool Preprocessor::SetCodeCompletionPoint	(	FileEntryRef	File,

Specify the point at which code-completion will be performed.

Parameters

File	the file in which code completion should occur. If this file is included multiple times, code-completion will perform completion the first time it is included. If NULL, this function clears out the code-completion point.
Line	the line at which code completion should occur (1-based).
Column	the column at which code completion should occur (1-based).

Returns: true if an error occurred, false otherwise.
