2012-01-31Use the new Triple::getMacOSXVersion function in another place.Bob Wilson
I removed support for "*-darwin*-iphoneos" triples, since we now have iOS listed as a separate OS in the triples. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149455 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-31Fix an assertion failure in isMacOSXVersionLT for IOS targets.Bob Wilson
Check if the triple OS is IOS instead of checking for arm/thumb architectures and check that before calling isMacOSXVersionLT. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149454 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-31Split compiler builtin module into "stdlib" builtins and "intrinsic"Douglas Gregor
builds, and bring mm_alloc.h into the fold. Start playing some tricks with these builtin modules to mirror the include_next tricks that the headers already perform. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149434 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-31Fix more fallout from the introduction of "macosx" and "ios" triples.Bob Wilson
The Darwin toolchain constructor was assuming that all Darwin triples would have an OS string starting with "darwin". Triples starting with "macosx" would misinterpret the version number, and "ios" triples would completely miss the version number (or worse) because the OS name is not 6 characters long. We lose some sanity checking of triple strings here, since the Triple.getOSVersion function doesn't do all the checking that the previous code did, but this still seems like a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149422 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes the case where Clang would output: error: format specifies type 'wchar_t *' (aka 'wchar_t *') ArgTypeResult::getRepresentativeTypeName needs to take into account that wchar_t can be a built-in type (as opposed to in C, where it is a typedef). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149387 91177308-0d34-0410-b5e6-96231b3b80d8

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).

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
