2013-04-20Disable VLA diagnostic in C++1y mode, and add some tests.Richard Smith
Still to do here: - we have a collection of syntactic accepts-invalids to diagnose - support non-PODs in VLAs, including dynamic initialization / destruction - runtime checks (and throw std::bad_array_length) for bad bound - support VLA capture by reference in lambdas - properly support VLAs in range-based for (don't recompute bound) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179962 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-20C++1y: Allow aggregates to have default initializers.Richard Smith
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.

2013-04-20[analyzer] Ensure BugReporterTracking works on regions with pointer arithmeticAnna Zaks
Introduce a new helper function, which computes the first symbolic region in the base region chain. The corresponding symbol has been used for assuming that a pointer is null. Now, it will also be used for checking if it is null. This ensures that we are tracking a null pointer correctly in the BugReporter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179916 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-17Extended VerifyDiagnosticConsumer to also verify source file for diagnostic.Andy Gibbs
VerifyDiagnosticConsumer previously would not check that the diagnostic and its matching directive referenced the same source file. Common practice was to create directives that referenced other files but only by line number, and this led to problems such as when the file containing the directive didn't have enough lines to match the location of the diagnostic in the other file, leading to bizarre file formatting and other oddities. This patch causes VerifyDiagnosticConsumer to match source files as well as line numbers. Therefore, a new syntax is made available for directives, for example: // expected-error@file:line {{diagnostic message}} This extends the @line feature where "file" is the file where the diagnostic is generated. The @line syntax is still available and uses the current file for the diagnostic. "file" can be specified either as a relative or absolute path - although the latter has less usefulness, I think! The #include search paths will be used to locate the file and if it is not found an error will be generated. The new check is not optional: if the directive is in a different file to the diagnostic, the file must be specified. Therefore, a number of test-cases have been updated with regard to this. This closes out PR15613. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179677 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-16[1/6] ARM Neon Intrinsic Tablegen Test Generator.Michael Gottesman
Changes necessary to arm_neon.td for the generation of Neon tests. This is the first of six patches to add to the arm neon tablegen generator the capability of generating tests to verify that the various ARM intrinsics are implemented properly. The changes include such items as: 1. Adding attributes to the Inst record so that additional metadata that is only needed for the tests can be specified in TableGen. 2. Adding wrapper classes for operator (i.e. ``Op'') intrinsics which before were simply notates as Inst. This allows us to classify what sort of test to generate for said intrinsic and further since the classes do not effect the behavior of the Inst base class, allow for normal functioning.
