2013-04-22[analyzer] Treat reinterpret_cast like a base cast in certain cases.Jordan Rose
The analyzer represents all pointer-to-pointer bitcasts the same way, but this can be problematic if an implicit base cast gets layered on top of a manual base cast (performed with reinterpret_cast instead of static_cast). Fix this (and avoid a valid assertion) by looking through cast regions. Using reinterpret_cast this way is only valid if the base class is at the same offset as the derived class; this is checked by -Wreinterpret-base-class. In the interest of performance, the analyzer doesn't repeat this check anywhere; it will just silently do the wrong thing (use the wrong offsets for fields of the base class) if the user code is wrong.

Add a CXXDefaultInitExpr, analogous to CXXDefaultArgExpr, and use it both in CXXCtorInitializers and in InitListExprs to represent a default initializer. There's an additional complication here: because the default initializer can refer to the initialized object via its 'this' pointer, we need to make sure that 'this' points to the right thing within the evaluation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179958 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-20Supports Sourcery CodeBench Mips toolchain directories tree.Simon Atanasyan
Sourcery CodeBench and modern FSF Mips toolchains require a bit more complicated algorithm to calculate headers, libraries and sysroot paths than implemented by Clang driver now. The main problem is that all these paths depend on a set of command line arguments additionally to a target triple value. For example, let $TC is a toolchain installation directory. If we compile big-endian 32-bit mips code, crtbegin.o is in the $TC/lib/gcc/mips-linux-gnu/4.7.2 folder and the toolchain's linker requires --sysroot=$TC/mips-linux-gnu/libc argument. If we compile little-endian 32-bit soft-float mips code, crtbegin.o is in the $TC/lib/gcc/mips-linux-gnu/4.7.2/soft-float/el folder and the toolchain's linker requires --sysroot=$TC/mips-linux-gnu/libc/soft-float/el argument. 1. Calculate MultiarchSuffix using all necessary command line options and use this MultiarchSuffix to detect crtbegin.o location in the GCCInstallationDetector::ScanLibDirForGCCTriple() routine. 2. If a user does not provide --sysroot argument to the driver explicitly, calculate new sysroot value based on command line options. Then use this calculated sysroot path: a. To populate a file search paths list in the Linux::Linux() constructor. b. To find Mips toolchain specific include headers directories in the Linux::AddClangSystemIncludeArgs() routine. c. To provide -–sysroot argument for a linker. Note: - The FSF's tree slightly differs (folder names) and is not supported yet. - New addExternCSystemIncludeIfExits() routine is a temporary solution. I plan to move path existence check to the addExternCSystemInclude() routine by a separate commit.

2013-04-19Avoid names like __in that conflict with SAL in builtin headersReid Kleckner
Microsoft's Source Annotation Language (SAL) defines a bunch of keywords for annotating the inputs and outputs of functions. Empty definitions for the keywords are provided by <stdlib.h> -> <crtdefs.h> -> <sal.h>. This makes it basically impossible to include MSVC's stdlib.h and Clang's *mmintrin.h headers at the same time if they have variables named __in. As a workaround, I've renamed those variables. This fixes the Modules/compiler_builtins.m test which was XFAILed, presumably due to this conflict. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179860 91177308-0d34-0410-b5e6-96231b3b80d8
