2011-10-31Simplify the set of directories we look for on multiarch systems.Chandler Carruth
I don't have any Debian system with one of these currently, and it seems unlikely for one to show up suddenly. We can add more patterns here if they become necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143346 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-31Fix part of PR11223 and probably a few dups as well. This teaches theChandler Carruth
library search logic to "properly" handle multiarch installations. I've tested this on both Debian unstable and the latest Ubuntu which both use this setup, and this appears to work largely the same way as GCC does. It isn't exactly the same, but it is close enough and more principled in its behavior where it differs. This should resolve any failures to find 'crt1.o' etc on Debian-based Linux distributions. If folks find more cases where we fail, please file bugs and CC me. Test cases for all of the debian silliness are waiting both to simplify the process of merging these down into the 3.0 release, and because they're so crazy I haven't yet been able to really produce a fake tree that represents what we need to test for. I'll eventually add them though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143344 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-16Clean up some cruft in the library path searching logic by makingChandler Carruth
'libdir' mean the actual library directory, not the GCC subdirectory of the library directory. That was just a confusing pattern. Instead, supply proper GCC subdirectories when scanning for various triple-based subdirectories with a GCC installation in them. This also makes it much more obvious how multiarch installations, which have a triple-based prefix as well as suffix work. Also clean up our handling of these triple-prefixed trees by using them in both a multiarch pattern and a non-multiarch pattern whenever they exist. Note that this *does not* match what GCC does on Debian, the only truly multiarch installation I've been able to get installed and test on. GCC appears to have a bug, and ends up searching paths like '/lib/../../lib32' which makes no sense what-so-ever. Instead, I've tried to encode the rational logic that seems clearly intended by GCC's pattern. GCC ends up with patterns like: /lib/../../lib32 /usr/lib/../../lib32 /usr/lib/x86_64-linux-gnu/../..lib32 Only the last one makes any sense having a '/../..' in it, so in Clang, that's the only one which gets a '/../..' in it. I *think* this will fix Debian multiarch links. I'm committing without baking this logic into our test suite so I can test on a few different systems. If all goes well (and no one screams) I'll check in some more comprehensive tests for multiarch behavior tomorrow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142133 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-14Use Triple.isOSDarwin() instead of comparing against Triple::Darwin.Bob Wilson
There are now separate Triple::MacOSX and Triple::IOS values for the OS so comparing against Triple::Darwin will fail to match those. Note that I changed the expected output for the Driver/rewrite-objc.m test, which had previously not been passing Darwin-specific options with the macosx triple. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141944 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-11Driver: Add support for a new -nostdlibinc option.Daniel Dunbar
- This disables the system include directories, but not the compiler builtin directories. Useful for projects that want to use things like the intrinsic headers, but are otherwise freestanding. - I'm willing to reconsider the option naming, I also considered providing an explicit -builtinc (which would match -nobuiltininc), but this is more consistent with existing options. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141692 91177308-0d34-0410-b5e6-96231b3b80d8
