2012-04-06Added a new attribute, objc_root_class, which informs the compiler when a ↵Patrick Beard
root class is intentionally declared. The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154187 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-06Fix using Clang as a cross compiler installed on a host machine and notChandler Carruth
inside of a sysroot targeting a system+sysroot which is "similar" or "compatible" with the host system. This shows up when trying to build system images on largely compatible hardware as-if fully cross compiled. The problem is that previously we *perfectly* mimiced GCC here, and it turns out GCC has a bug that no one has really stumbled across. GCC will try to look in thy system prefix ('/usr/local' f.ex.) into which it is instaled to find libraries installed along side GCC that should be preferred to the base system libraries ('/usr' f.ex.). This seems not unreasonable, but it has a very unfortunate consequence when combined with a '--sysroot' which does *not* contain the GCC installation we're using to complete the toolchain. That results in some of the host system's library directories being searched during the link. Now, it so happens that most folks doing stuff like this use '--with-sysroot' and '--disable-multilib' when configuring GCC. Even better, they're usually not cross-compiling to a target that is similar to the host. As a result, searching the host for libraries doesn't really matter -- most of the time weird directories get appended that don't exist (no arm triple lib directory, etc). Even if you're cross-compiling from 32-bit to 64-bit x86 or vice-versa, disabling multilib makes it less likely that you'll actually find viable libraries on the host. But that's just luck. We shouldn't rely on this, and this patch disables looking in the system prefix containing the GCC installation if that system prefix is *outside* of the sysroot. For empty sysroots, this has no effect. Similarly, when using the GCC *inside* of the sysroot, we still track wherever it is installed within the sysroot and look there for libraries. But now we can use a cross compiler GCC installation outside the system root, and only look for the crtbegin.o in the GCC installation, and look for all the other libraries inside the system root. This should fix PR12478, allowing Clang to be used when building a ChromiumOS image without polluting the image with libraries from the host system. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154176 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-06Restrict fixit for missing 'class' in template template parameters.David Blaikie
Based on Doug's feedback to r153887 this omits the FixIt if the following token isn't syntactically valid for the context. (not a comma, '...', identifier, '>', or '>>') There's a bunch of work to handle the '>>' case, but it makes for a much more pleasant diagnostic in this case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154163 91177308-0d34-0410-b5e6-96231b3b80d8
