DeLesley Hutchins ae497deddf Thread Safety Analysis: Update SSA pass to handle loops. 
llvm-svn: 206676
 2014-04-19 00:35:54 +00:00
Aaron Ballman ed5aced64e Since the object is new'ed in the enterCFG function, now deleting in the exitCFG function instead of the destructor to ensure proper pairing. This allows reuse of the builder without creating a memory leak.

DeLesley Hutchins aab9aff058 Thread Safety Analysis: rewrite SSA pass to use the new SExpr and CFG 
traversal system.  The new pass is still undergoing testing; no change in
functionality.

DeLesley Hutchins 7e615c2f65 Thread Safety Analysis: reorganized SExpr header files. No change in 
functionality.

Aaron Ballman 28347a72c9 Thread Safety Analysis: now with less includes. No functional changes.

Aaron Ballman 3f993c1320 Thread Safety Analysis: some minor cleanups to the latest thread safety changes. No functional changes intended. 
* Adds an iterator_range interface to CallExpr to get the arguments
* Modifies SExpr such that it must be allocated in the Arena, and cannot be deleted
* Minor const-correctness and nullptr updates
* Adds some operator!= implementations to complement operator==
* Removes unused functionality

DeLesley Hutchins 11bb308739 Thread Safety Analysis: various fixes to new SExpr code. 
Implemented ownership policy, updated to use nullptr, const-cleanup.

DeLesley Hutchins b2213910de Thread Safety Analysis: update to internal SExpr handling. 
This patch is the first part of a significant refactoring that seeks to restore
sanity to way thread safety analysis deals with capability expressions.  The
current patch merely provides an outline of the structure of the new system.
It's not yet connected to the actual analysis, so there's no change in
functionality.
