2012-07-11Don't process #pragma visibility during instantiation. The visibility of theRafael Espindola
instantiation depends on the template, its arguments and parameters, but not where it is instantiated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160034 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-11The end of a block doesn't necessarily need a line table entry unlessEric Christopher
there's something going on there. Remove the unconditional line entry and only add one if we're emitting cleanups (any other statements would be handled normally). Fixes rdar://9199234 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160033 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-10[analyzer] Add debug.DumpCalls, which prints out any CallEvents it sees.Jordan Rose
This is probably not so useful yet because it is not path-sensitive, though it does try to show inlining with indentation. This also adds a dump() method to CallEvent, which should be useful for debugging. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160030 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-10[analyzer] Guard against C++ member functions that look like system functions.Jordan Rose
C++ method calls and C function calls both appear as CallExprs in the AST. This was causing crashes for an object that had a 'free' method. <rdar://problem/11822244> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160029 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-10[analyzer] Construct stack variables directly in their VarDecl.Jordan Rose
Also contains a number of tweaks to inlining that are necessary for constructors and destructors. (I have this enabled on a private branch, but it is very much unstable.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160023 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-10[analyzer] Use CallEvent for building inlined stack frames.Jordan Rose
In order to accomplish this, we now build the callee's stack frame as part of the CallEnter node, rather than the subsequent BlockEdge node. This should not have any effect on perceived behavior or diagnostics. This makes it safe to re-enable inlining of member overloaded operators. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160022 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-10[analyzer] Make CallEnter, CallExitBegin, and CallExitEnd not be StmtPointsJordan Rose
These ProgramPoints are used in inlining calls, and not all calls have associated statements anymore. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160021 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-10[analyzer] Add a CXXDestructorCall CallEvent.Jordan Rose
While this work is still fairly tentative (destructors are still left out of the CFG by default), we now handle destructors in the same way as any other calls, instead of just automatically trying to inline them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160020 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-10[analyzer] Add new PreImplicitCall and PostImplicitCall ProgramPoints.Jordan Rose
These are currently unused, but are intended to be used in lieu of PreStmt and PostStmt when the call is implicit (e.g. an automatic object destructor). This also modifies the Data1 field of ProgramPoints to allow storing any pointer-sized value, as opposed to only aligned pointers. This is necessary to store SourceLocations. There is currently no BugReporter support for these; they should be skipped over in any diagnostic output. This commit also tags checkers that currently rely on function calls only occurring at StmtPoints. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160019 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-09Better parser recovery in Objective-C containers.Jordan Rose
Previously it was possible to get an infinite-loop-on-invalid with a namespace decl within @interface. Since 'namespace' is normally a safe place to retry top-level parsing, we just didn't consume the token. This adds a flag that tracks whether we have temporarily left Objective-C scope to parse a C-like declaration, and uses that to better recover from parse problems by stopping at possible method declarations and at @end. To fix the original problem, we do /not/ stop at 'namespace' when in an Objective-C @interface or @protocol context (but still do in @implementation). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159941 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-09[analyzer] When inlining, make sure we use the definition decl.Jordan Rose
This was a regression introduced during the CallEvent changes; a call to FunctionDecl::hasBody was also being used to replace the decl found by lookup with the actual definition. To keep from making this mistake again (particularly if/when we start inlining Objective-C methods), this commit adds a "getDefinition()" method to CallEvent, which should do the right thing under any circumstances. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159940 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-09Downgrade the "direct comparison" error for ObjC literals to a warning.Jordan Rose

Revert the release notes change (r159766) now that this is just a new warning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159939 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-09PR13136:Richard Smith
* When substituting a reference to a non-type template parameter pack where the corresponding argument is a pack expansion, transform into an expression which contains an unexpanded parameter pack rather than into an expression which contains a pack expansion. This causes the SubstNonTypeTemplateParmExpr to be inside the PackExpansionExpr, rather than outside, so the expression still looks like a pack expansion and can be deduced. * Teach MarkUsedTemplateParameters that we can deduce a reference to a template parameter if it's wrapped in a SubstNonTypeTemplateParmExpr (such nodes are added during alias template substitution). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159922 91177308-0d34-0410-b5e6-96231b3b80d8
