Add initial support for applying the sysroot to library search paths. This is still very much a WIP, but sysroot was completely broken before this so we are moving closer to correctness. The crux of this is that 'ld' (on Linux, the only place I'm touching here) doesn't apply the sysroot to any flags given to it. Instead, the driver must translate all the paths it adds to the link step with the system root. This is easily observed by building a GCC that supports sysroot, and checking its driver output. This patch just fixes the non-multilib library search paths. We should also use this in many other places, but first things first. This also allows us to make the Linux 'ld' test independent of the host system. This in turn will allow me to check in test tree configurations based on various different distro's configuration. Again, WIP. llvm-svn: 140990

// General tests that ld invocations on Linux targets sane. Note that we use
// sysroot to make these tests independent of the host system.
Add a test that ensures we get the basic multilib '-L' flags to 'ld' invocations on Linux. llvm-svn: 140909

// CHECK-LD-32: "{{.*}}ld{{(.exe)?}}" "--sysroot=[[SYSROOT:[^"]+]]"
Relax an assertion here a bit. This doesn't really matter, as we won't include *any* path on crtbegin.o unless we actually find such a file via one of the search paths. We still strictly check the search paths right after this, so we'll catch any issues there. The reason for this is that the driver does some normalization of the path on the actual object file, and this changes the textual format of the string on Windows. It no longer matches the textual format of the sysroot flag. llvm-svn: 140998

Teach the logic for locating an installed GCC about the system root. This requires fixing a latent bug -- if we used the default host triple instead of an autodetected triple to locate GCC's installation, we didn't go back and fix the GCC triple. Correct that with a pile of hacks. This entire routine needs a major refactoring which I'm saving for a subsequent commit. Essentially, the detection of the GCC triple should be hoisted into the same routine as we locate the GCC installation: the first is intrinsically tied to the latter. Then the routine will just return the triple and base directory. Also start to bring the rest of the library search path logic under test, including locating crtbegin.o. Still need to test the multilib and other behaviors, but there are also bugs in the way of that. llvm-svn: 140995

Enable generic multilib support on 32bit hosts. Previously this was only enabled for debian hosts, which is quite odd. I think all restriction on when Clang attempts to use a multilib installation should go away. Clang is fundamentally a cross compiler. It behaves more like GCC when built as a cross compiler, and so it should just use multilib installs when they are present on the system. However, there is a very specific exemption for Exherbo, which I can't test on, so I'm leaving that in place. With this, check in a generic test tree for multilib on a 32-bit host. This stubs out many directories that most distributions don't use but that uptsream GCC supports. This is intended to be an agnostic test that the driver behaves properly compared with the GCC driver it aims for compatibility with. Also, fix a bug in the driver that this testing exposed (see!) where it was incorrectly testing the target architecture rather than the host architecture. If anyone is having trouble with the tree-structure stubs I'm creating to test this, let me know and I can revisit the design. I chose this over (for example) a tar-ball in order to make tests run faster at the small, hopefully amortized VCS cost. llvm-svn: 140999

Implement the feature I was originally driving toward when I started this saga. Teach the driver to detect a GCC installed along side Clang using the existing InstalledDir support in the Clang driver. This makes a lot of Clang's behavior more automatic when it is installed along side GCC. Also include the first test cases (more to come, honest) which test both the install directory behavior, and the version sorting behavior to show that we're actually searching for the best candidate GCC installation now. llvm-svn: 141145

Implement the feature I was originally driving toward when I started this saga. Teach the driver to detect a GCC installed along side Clang using the existing InstalledDir support in the Clang driver. This makes a lot of Clang's behavior more automatic when it is installed along side GCC. Also include the first test cases (more to come, honest) which test both the install directory behavior, and the version sorting behavior to show that we're actually searching for the best candidate GCC installation now. llvm-svn: 141145

Enhance the GCC version parsing and comparison logic to handle some more edge cases and have better behavior. Specifically, we should actually prefer the general '4.6' version string over the '4.6.1' string, as '4.6.2' should be able to replace it without breaking rpaths or any other place that these paths have been embedded. Debian-based distributions are already using a path structure with symlinks to achieve in-place upgrades for patch versions. Now our parsing reflects this and we select the shorter paths instead of the longer paths. A separate issue was that we would not parse a leading patch version number even in the presence of a suffix. The above change makes this more problematic as it would cause a suffix being added to make us treat the entire thing as patch-version-agnostic, which it isn't. This changes the logic to distinguish between '4.4.x' and 4.4.1-x', and retain that the latter has *some* patch number information. Currently, we always bias toward the shorter and more canonical version strings. If it becomes important we can add more Debian like rules to produce sequences such as '4.4.1b' > '4.4.1' > '4.4.1-rc3' > '4.4.1-rc2' > '4.4.1-pre5', but I'm very doubtful this will ever matter or be desirable. I've made the tests for this logic a bit more interesting, and added some specific tests for logic that is now different. llvm-svn: 143841

Add support for PPC and PPC64 multiarch toolchains on Debain. Patch from Michel Dänzer, sent our way via Jeremy Huddleston who added 64-bit support. I just added one other place where powerpc64-linux-gnu was missing (we only had powerpc64-unknown-linux-gnu). I've also added a tree to test out the debian multiarch stuff. I don't use debian regularly, so I'm not certain this is entirely accurate. If anyone wants to check it against a debian system and fix any inaccuracies, fire away. This way at least folks can see how this is *supposed* to be tested. It'd be particularly good to get the Debian MIPS toolchains tested in this way. llvm-svn: 151482
