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()
|
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 1721 of file ThreadSafetyTIL.h.
◆ numBlocks()
|
inline |
Return the number of blocks in the CFG.
Block::blockID() will return a number less than numBlocks();

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