bool LiveVariables::isLive ( const CFGBlock B,

Return true if a variable is live at the end of a specified block.

bool LiveVariables::isLive ( const Stmt S,
const VarDecl D 
)

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.

bool LiveVariables::isLive ( const Stmt Loc,
const Stmt StmtVal 
)

Returns true the block-level expression "value" is live before the given block-level expression (see runOnAllBlocks).
