2014-02-27	Rework CFG edges to encode potentially unreachable edges, instead of just ↵	Ted Kremenek	1	-1/+2
	making them NULL. This is to support some analyses, like -Wunreachable-code, that will need to recover the original unprunned CFG edges in order to suppress issues that aren't really bugs in practice. There are two important changes here: - AdjacentBlock replaces CFGBlock* for CFG successors/predecessors. This has the size of 2 pointers, instead of 1. This is unlikely to have a significant memory impact on Sema since a single CFG usually exists at one time, but could impact the memory usage of the static analyzer. This could possibly be optimized down to a single pointer with some cleverness. - Predecessors can now contain null predecessors, which means some analyses doing a reverse traversal will need to take into account. This already exists for successors, which contain successor slots for specific branch kinds (e.g., 'if') that expect a fixed number of successors, even if a branch is not reachable. llvm-svn: 202325
2013-08-23	Use pop_back_val() instead of both back() and pop_back().	Robert Wilhelm	1	-5/+4
	No functionality change intended. llvm-svn: 189112
2011-07-23	remove unneeded llvm:: namespace qualifiers on some core types now that ↵	Chris Lattner	1	-1/+1
	LLVM.h imports them into the clang namespace. llvm-svn: 135852
2011-03-19	Rename class 'CFGReachabilityAnalysis' to 'CFGReverseBlockReachabilityAnalysis'.	Ted Kremenek	1	-3/+3
	This rename serves two purposes: - It reflects the actual functionality of this analysis. - We will have more than one reachability analysis. llvm-svn: 127930
2011-02-23	Migrate CFGReachabilityAnalysis out of the IdempotentOperationsChecker and ↵	Ted Kremenek	1	-0/+76
	into its own analysis file. llvm-svn: 126289
