2011-09-19Remove function which is unused as of r139996. Thanks to David Blaikie for ↵Richard Smith
bringing this to my attention. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140013 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19Do not use builtin includes if -fms-compatibility is specified. Some MSVC ↵Francois Pichet
header files have the same name as clang's builtins, this creates clash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140009 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-18Move the "jump bypasses variable initialization" error -> warning downgrade ↵Francois Pichet
from -fms-extensions to -fms-compatibility. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140008 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-18In Microsoft mode(-fms-compatibility), prefer an integral conversion to a ↵Francois Pichet
floating-to-integral conversion if the integral conversion is between types of the same size. For example: void f(float); void f(int); int main { long a; f(a); } Here, MSVC will call f(int) instead of generating a compile error as clang will do in standard mode. This fixes a few errors when parsing MFC code with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140007 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-18PR10304: Do not call destructors for data members from union destructors. ↵Richard Smith
Prior to C++11, this has no effect since any such destructors must be trivial, and in C++11 such destructors must not be called. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139997 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-18PR10954: variant members should not be implicitly initialized in ↵Richard Smith

2011-09-18Fix PR10531. Attach an initializer to anonymous unions, since the default ↵Richard Smith
constructor might not be trivial (if there is an in-class initializer for some member) and might be deleted. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139991 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-17Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear ↵Francois Pichet
that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag. Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139987 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-17When we load header file information from the external source (i.e.,Douglas Gregor
the AST reader), merge that header file information with whatever header file information we already have. Otherwise, we might forget something we already knew (e.g., that the header was #import'd already). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139979 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-17As per discussion with Doug Gregor on the IRC channel, introduce a new ↵Francois Pichet
compiler switch: -fms-compatility. Microsoft specific tweaking will now fall into 2 categories: - fms-extension: Microsoft specific extensions that should never change the meaning of an otherwise well formed code. Currently map to LangOptions::Microsoft. (To be clearer, I am planning to change the name to LangOptions::MicrosoftExt). - fms-compatibility: Really a MSVC emulation mode. Map to LangOptions::MicrosoftMode. Can change the meaning of an otherwise standard conformant program. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139978 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-17With modules, we can end up loading a new module after we've seen anDouglas Gregor
arbitrary amount of code. This forces us to stage the AST writer more strictly, ensuring that we don't assign a declaration ID to a declaration until after we're certain that no more modules will get loaded. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139974 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-16In Microsoft mode, warn if an indirect goto jump over a variable initialization.Francois Pichet
Also add a test case for the non Microsoft case because such test didn't exist. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139971 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-16Fix massive LiveVariables regression (due to LiveVariables rewrite) by ↵Ted Kremenek
addressing two performance problems: - Speed of "merge()", which merged data flow facts. This was doing a set canonicalization on every insertion, which was super slow. To fix this, we use ImmutableSetRef. - Visit CFGBlocks in reverse postorder. This is a huge speedup, as on some test cases the algorithm would take many iterations to converge. This contains a bunch of copy-paste from UninitializedValues.cpp and ThreadSafety.cpp. The idea was to get something working first, and then refactor the common logic for all three files into a separate analysis/library entry point. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139968 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-16[analyzer] Refactor: make PathDiagnosticLocation responsible for validation ↵Anna Zaks
of SourceLocations (commit 5 of ?): - Get rid of PathDiagnosticLocation(SourceRange r,..) constructor by providing a bunch of create methods. - The PathDiagnosticLocation(SourceLocation L,..), which is used by crate methods, will eventually become private. - Test difference is in the case when the report starts at the beginning of the function. We used to represent that point as a range of the very first token in the first statement. Now, it's just a single location representing the first character of the first statement. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139932 91177308-0d34-0410-b5e6-96231b3b80d8
