◆ getTag() ◆ isLive() [1/3] ◆ isLive() [2/3] bool LiveVariables::isLive ( const Stmt * Loc, const Expr * Val )Returns true the block-level expression value is live before the given block-level expression (see runOnAllBlocks).
Definition at line 149 of file LiveVariables.cpp.
References getImpl(), and Loc.
◆ isLive() [3/3]Returns true if a variable is live at the beginning of the the statement.
This query only works if liveness information has been recorded at the statement level (see runOnAllBlocks), and only returns liveness information for block-level expressions.
