Richard Smith 4baaa5ab52 DR616, and part of P0135R1: member access (or pointer-to-member access) on a 
temporary produces an xvalue, not a prvalue. Support this by materializing the
temporary prior to performing the member access.

variables as well member variables.

Chandler Carruth 0d9593ddec [cleanup] Re-sort *all* #include lines with llvm/utils/sort_includes.py 
Sorry for the noise, I managed to miss a bunch of recent regressions of
include orderings here. This should actually sort all the includes for
Clang. Again, no functionality changed, this is just a mechanical
cleanup that I try to run periodically to keep the #include lines as
regular as possible across the project.

DeLesley Hutchins 4e38f100b5 Thread Safety Analysis: major update to thread safety TIL. 
Numerous changes, including:
  * Changed the way variables and instructions are handled in basic blocks to
    be more efficient.
  * Eliminated SExprRef.
  * Simplified futures.
  * Fixed documentation.
  * Compute dominator and post dominator trees.

DeLesley Hutchins 4266522ab9 Thread safety analysis: Add support for negative requirements, which are 
capability expressions of the form !expr, and denote a capability that must
not be held.

DeLesley Hutchins ea1f83385f Thread Safety Analysis: Replace the old and broken SExpr with the new 
til::SExpr.  This is a large patch, with many small changes to pretty printing
and expression lowering to make the new SExpr representation equivalent in
functionality to the old.

DeLesley Hutchins b603192124 Thread Safety Analysis: implement review suggestions from Aaron Ballman.

DeLesley Hutchins 44be81b5a9 Thread Safety Analysis: update TIL traversal mechanism to allow arbitrary 
local contexts.  Also includes some minor refactoring.

DeLesley Hutchins f4b5e7c60f Thread Safety Analysis: add new node types to thread safety TIL. 
This fills in a few missing gaps in functionality.

Benjamin Kramer a7bcab75d2 ThreadSafetyAnalysis: Don't crash when trying to analyze objc methods. 
The thread safety analysis isn't very useful in ObjC (you can't annotate
ObjC classes or methods) but we can still analyze the actual code and
show violations in usage of C/C++ functions.

Fixes PR19541, which does not use thread safety attributes but crashes
with -Weverything.

Aaron Ballman 8e8026d5b3 Replacing a naked pointer with a unique_ptr. No functional changes intended.

Aaron Ballman bf58a6a892 Updated to be a bit more const friendly. Also switched the linkage to be static since this function is file-local. No functional changes intended.

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.

 2014-04-09 21:12:04 +00:00
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 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.
