2012-01-31constexpr: the result of a relational operator between pointers to void isRichard Smith
unspecified unless the pointers are equal; therefore, such a comparison is not a constant expression unless the pointers are equal. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149366 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-31ConstantArray::get() (for strings) is going away, useChris Lattner
ConstantDataArray::getString instead. Many instances of ConstantArray::get() could be moved to use more efficient ConstantDataArray methods that avoid a ton of intermediate Constant*'s for each element (e.g. GetConstantArrayFromStringLiteral). I don't plan on doing this in the short-term though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149363 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-31Revert r149083 which is not the direction we're going in the ClangChandler Carruth
driver based on discussions with Doug Gregor. There are several issues: 1) The patch was not reviewed prior to commit and there were review comments. 2) The design of the functionality (triple-prefixed tool invocation) isn't the design we want for Clang going forward: it focuses on the "user triple" rather than on the "toolchain triple", and forces that bit of state into the API of every single toolchain instead of handling it automatically in the common base classes. 3) The tests provided are not stable. They fail on a few Linux variants (Gentoo among them) and on mingw32 and some other environments. I *am* interested in the Clang driver being able to invoke triple-prefixed tools, but we need to design that feature the right way. This patch just extends the previous hack without fixing the underlying problems with it. I'm working on a new design for this that I will mail for review by tomorrow. I am aware that this removes functionality that NetBSD relies on, but this is ToT, not a release. This functionality hasn't been properly designed, implemented, and tested yet. We can't "regress" until we get something that really works, both with the immediate use cases and with long term maintenance of the Clang driver. For reference, the original commit log: Keep track of the original target the user specified before normalization. This used to be captured in DefaultTargetTriple and is used for the (optional) $triple-$tool lookup for cross-compilation. Do this properly by making it an attribute of the toolchain and use it in combination with the computed triple as index for the toolchain lookup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149337 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-30Fix yet another issue introduced when renaming '-ccc-host-triple' toChandler Carruth
'-target'. The original flag was part of a flag group that marked it as driver-only. The new flag didn't ever get equivalent treatment.

2012-01-30Introduce TargetInfo::hasFeature() to query various feature names inDouglas Gregor
each of the targets. Use this for module requirements, so that we can pin the availability of certain modules to certain target features, e.g., provide a module for xmmintrin.h only when SSE support is available. Use these feature names to provide a nearly-complete module map for Clang's built-in headers. Only mm_alloc.h and unwind.h are missing, and those two are fairly specialized at the moment.
