Chris Lattner affc0e42f0 fix more AST updating bugs, correcting miscompilation in PR8041 
llvm-svn: 112878
 2010-09-02 22:19:10 +00:00
John McCall 25f7aa8158 Experimentally move the tautological comparison warnings from -Wsign-compare 
to -Wtautological-compare.  This implies that they're now on by default.
If this causes chaos, I'll figure something else out.

Owen Anderson 2912df072d Remove incorrect and poorly tested code for trying to reason about values on default edges of 
switches.  Just return the conservatively correct answer.

John McCall 7f55c258c6 After some discussion with djg, teach SmallVector to grow from a zero 
capacity and remove the workaround in SmallVector<T,0>.  There are some
theoretical benefits to a N->2N+1 growth policy anyway.

Douglas Gregor 6429f5cf29 Eliminate CXXBindReferenceExpr, which was used in a ton of 
well-intentioned but completely unused code.

Greg Clayton 6dadd508e7 Added a new bool parameter to many of the DumpStopContext() methods that 
might dump file paths that allows the dumping of full paths or just the
basenames. Switched the stack frame dumping code to use just the basenames for
the files instead of the full path.

Modified the StackID class to no rely on needing the start PC for the current
function/symbol since we can use the SymbolContextScope to uniquely identify
that, unless there is no symbol context scope. In that case we can rely upon
the current PC value. This saves the StackID from having to calculate the 
start PC when the StackFrame::GetStackID() accessor is called.

Also improved the StackID less than operator to correctly handle inlined stack
frames in the same stack.

Johnny Chen 7d1d7537cf Moved the process cleanup of Script-Bridge-based APIs into TestBase.tearDown() 
method where they belong.  Also fixed a logic error in maintaining the command
interface flag (runStarted) indicating whether the lldb "run"/"process launch"
command has been issued.  It was erroneously cleared.

Modified the test cases to take advantage of the refactoring.

Dan Gohman 3c9b5f394b Don't narrow the load and store in a load+twiddle+store sequence unless 
there are clearly no stores between the load and the store. This fixes
this miscompile reported as PR7833.

This breaks the test/CodeGen/X86/narrow_op-2.ll optimization, which is
safe, but awkward to prove safe. Move it to X86's README.txt.

Dan Gohman 9e857449de Apply a patch from Kees van Reeuwijk to add support for Minix. 
Minix apparently doesn't like double-slash separators, and there's
no apparent need for them here.

Tom Care 1ce2faca05 Improved error reporting in IdempotentOperationChecker 
- SourceRange highlighting is only given for the relevant side of the operator (assignments give both)
- Added PostVisitBinaryOperator hook to retrieve the ExplodedNode for an operator
- Added a BugReporterVisitor to display the last store to every VarDecl in a Stmt
- Changed bug reporting to use the new BugReporterVisitor

based on ConvertTypeForMem. Thanks to John for pointing out the right
solution.

Douglas Gregor 3335f48448 Implement basic visitation for nested name specifiers via libclang 
cursors. Sadly, this visitation is a hack, because we don't have
proper source-location information for nested-name-specifiers in the
AST. It does improve on the status quo, however.

Douglas Gregor 262e4e2ab5 Fix more i1/i8 pointer madness. Here, an overactive assertion 
complains when the element type of a C++ "delete" expression is
different from what we would expect from the pointer type. When
deleting a bool*, we end up with an i1 on one side (where we compute
the LLVM type from the Clang bool type) and i8 on the other (where we
grab the LLVM type from the LLVM pointer type). I've weakened the
assertion appropriately, and the Boost Parallel Graph Library now
passes its regression tests.
