2008-04-01MemoryBuffer::getFile got smarter, obviating the need for readfilefast.Chris Lattner
The new MemoryBuffer doesn't "leak" file descriptors and handles the small file case efficiently. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49032 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49001 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31When emitting HTML messages, take into account margin fusing due to tabs.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48998 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Do not abort ccc-analyzer script if an HTML directory is not specified.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48997 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Do not prepend the keyword "[CHECKER]" to checker messages when usingTed Kremenek
a PathDiagnosticClient. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48996 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Hack ReadFileFast() to raise the threshold of memory mapped files (from ↵Steve Naroff
4->12 pages). This is a temporary solution to avoid running out of file descriptors (which defaults to 256). Need to benchmark to understand the speed benefit. If the benefit is small, the simple solution is to avoid memory mapping files. If the benefit is significant, more thought is necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48991 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Include ranges in GRSimpleVals diagnostics.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48990 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Inlined clang/Analysis/Analyses/GRSimpleVals.h into LocalCheckers.h and removedTed Kremenek
GRSimpleVals.h Added a PathDiagnosticClient option to the driver functions for the CFRefCountChecker and the GRSimpleVals analysis. Both analyses now accept a "-o" argument from the driver that specifies where HTML reports should be dumped. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48989 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31The ccc-analyzer script now interrogates environment variables to determineTed Kremenek
where to dump HTML reports. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48987 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Added variation of the "Report" method in the class Diagnostic that takesTed Kremenek
an optional DiagnosticClient argument that differs from the client stored internally in the Diagnostic object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48986 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Disable timing diagnostics for GRSimpleVals.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48981 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31Added path-sensitive check for return statements that return the addressTed Kremenek
of a stack variable. This is the path-sensitive version of a check that is already done during semantic analysis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48980 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-31rename Decl::CompatibleAlias -> ObjCCompatibleAlias.Chris Lattner
Fix objc ivar lookup. Ivar lookup should occur between lookup of method-local values and lookup of globals. Emulate this with some logic in the handling of Sema::ActOnIdentifierExpr. Two todo's left: 1) sema shouldn't turn a bare reference to an ivar into "self->ivar" in the AST. This is a hack. 2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does not correctly handle typedefs and enum constants yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48972 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-30some cleanups on top of David's patch. There are still twoChris Lattner
remaining open issues I've communicated to him: 1) self can be assigned to, and his patch didn't handle it correctly. 2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses all parent class ivars) and flattens classes. If A derives from B, and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}. David, please review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48970 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-30Add initial support for objc codegen for methods, ivars, and theChris Lattner
etoile runtime, patch by David Chisnall! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48969 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-28Only have the rewriter produce a file when there are no errors.Steve Naroff
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48926 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-28Added skeleton checking for NSString's method initWithFormat: (do not pass ↵Ted Kremenek
nil). This won't be useful in most cases right now because the analyzer isn't tracking expected types for an object, and [NSString alloc] just runs "id". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48917 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48895 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-27ProgramPoint is just a smart pointer; no reason to return a constant reference.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48891 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-27Added AnnotatedPath.h, GRAuditor.h, GRSimpleAPICheck.h and ↵Ted Kremenek
BasicObjCFoundationChecks.cpp to Xcode project. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48868 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-27Added "GRAuditor" and "GRSimpleAPICheck" interface to allow simple stateless ↵Ted Kremenek
checkers to be injected into the analyzer. Added "AnnotatedPath" class to record an annotated path that will be useful for inspecting paths. Added some boilerplate code for simple checks of Apple's Foundation API. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48867 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-27Added "HTMLDiagnostic", a generic DiagnosticClient (that also implements ↵Ted Kremenek
PathDiagnostic) so that all diagnostics can be piped to HTML files instead of as text diagnostics using --html-diags. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48865 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-27In ObjCMessageExpr: getSelector() const should just return "Selector", not ↵Ted Kremenek
"const Selector&" because Selector is just a smart pointer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48860 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-26Fix rewriter tests to work with new output file logic. This changes forces ↵Steve Naroff

DeclRefExpr, not it's address). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48846 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-26Added test case for static analysis to warn about passing uninitialized ↵Ted Kremenek
values as arguments (not the receiver) in message expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48845 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-26Added test case for static analyzer to detect uses of uninitialized pointers ↵Ted Kremenek
as receivers in Objective-C message expressions. Added test case directory "Analysis-Apple" which is only run on Apple (darwin) machines. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48844 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-26Bug fix in transfer function for ObjCMessageExpr: Visit the receiver ↵Ted Kremenek
expression as an ordinary expression, not using VisitLVal. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48842 91177308-0d34-0410-b5e6-96231b3b80d8
