2012-09-21[PCH] After deserializing a DeclContext, if it has external lexical decls ↵Argyrios Kyrtzidis
but not external visible decls, call DeclContext::setMustBuildLookupTable so that the "lazy decls" bit of the LookupPtr is set. Previously, in non-C++, if there were no new declarations causing the "lazy decls" bit to be set, then DeclContext::lookups_begin() would fail to return the decls from the PCH. Fixes rdar://12316296. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164351 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-21ARM: Use a dedicated intrinsic for vector bitwise select.Jim Grosbach
The expression based expansion too often results in IR level optimizations splitting the intermediate values into separate basic blocks, preventing the formation of the VBSL instruction as the code author intended. In particular, LICM would often hoist part of the computation out of a loop. rdar://11011471 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164342 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-21Implement faux-body-synthesis of well-known functions in the static analyzer ↵Ted Kremenek
when their implementations are unavailable. Start by simulating dispatch_sync(). This change is largely a bunch of plumbing around something very simple. We use AnalysisDeclContext to conjure up a fake function body (using the current ASTContext) when one does not exist. This is controlled under the analyzer-config option "faux-bodies", which is off by default. The plumbing in this patch is largely to pass the necessary machinery around. CallEvent needs the AnalysisDeclContextManager to get the function definition, as one may get conjured up lazily. BugReporter and PathDiagnosticLocation needed to be relaxed to handle invalid locations, as the conjured body has no real source locations. We do some primitive recovery in diagnostic generation to generate some reasonable locations (for arrows and events), but it can be improved. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164339 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-20If the range in a for range statement doesn't have a viable begin/end function,Richard Smith
but can be dereferenced to form an expression which does have viable begin/end functions, then typo-correct the range, even if something else goes wrong with the statement (such as inaccessible begin/end or the wrong type of loop variable). In order to ensure we recover correctly and produce any followup diagnostics in this case, redo semantic analysis on the for-range statement outside of the diagnostic trap, after issuing the typo-correction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164323 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-20Make the wchar_t promotion test consistent across different hosts by ↵David Blaikie
specifying a target triple. This test behavior differs depending (at least) on whether sizeof(wchar_t) == sizeof(int) or not. When they are equal, the first redeclaration will fail because decltype(+L'x') is unsigned int instead of the expected int. This occurs on ARM. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164315 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-20Remove a test that is non-portable (cannot be execute on cross builds, for ↵David Blaikie
example) While it might be nice to have a quick end-to-end sanity test, it's just not really the right place for it & would require more work to enable lit to provide a detection flag ("XFAIL: cross" or similar) than the value we get from having this test. Early on it might've made more sense, but these days we've got some pretty good coverage across the stack with more targeted tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164314 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-20Include types when a definition's type differs from a prior declaration.David Blaikie
This is some really old code (took me a while to find the test cases) & the diagnostic text is slightly incorrect (it should really only apply to re/declarations/, redefinitions are an error regardless of whether the types match). Not sure if anyone cares about it, though. For now this just makes the diagnostic more clear in less obvious cases where the type of a declaration might not be explicitly written (eg: because it uses decltype) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164313 91177308-0d34-0410-b5e6-96231b3b80d8
