Detailed Description

An SCFG is a control-flow graph.

It consists of a set of basic blocks, each of which terminates in a branch to another basic block. There is one entry point, and one exit point.

◆ normal()

bool clang::threadSafety::til::SCFG::normal ( ) const
inline

Return true if this CFG has been normalized.

After normalization, blocks are in topological order, and block and instruction IDs have been assigned.

Definition at line 1725 of file ThreadSafetyTIL.h.

◆ numBlocks()

size_t clang::threadSafety::til::SCFG::numBlocks ( ) const
inline

Return the number of blocks in the CFG.

Block::blockID() will return a number less than numBlocks();

Definition at line 1743 of file ThreadSafetyTIL.h.

References clang::threadSafety::til::SimpleArray< T >::size().

◆ numInstructions()

unsigned clang::threadSafety::til::SCFG::numInstructions ( )
inline

Return the total number of instructions in the CFG.

This is useful for building instruction side-tables; A call to SExpr::id() will return a number less than numInstructions().
