2011-10-04Fix Windows+MinGW which introduces noise into path separators.Chandler Carruth
There should be a better solution to this; Michael and I are continuing to discuss exactly what it should be. The one solution I'm very uncomfortable with is making the FileCheck tests use a regex for each path separator. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141126 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-04Now that multiple prefixes are much cheaper to search for GCCChandler Carruth
installations, support them when installed directly under the system root ('/lib/gcc/...' essentially). With this, Clang can correctly detect and use a cross-compiling GCC installation within a system root and use it. Again, test cases will be coming in later commits, as I'm going to write a few test cases that exercise nearly all of this logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141121 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-04Rework the search for a GCC installation still further. This combinesChandler Carruth
two fundamental changes, as they ended up being interrelated. The first is to walk from the root down through the filesystem so that we prune subtrees which do not exist early. This greatly reduces the filesystem traffic of this routine. We store the "best" GCC version we encounter, and look at all of the GCC installations available. Also, we look through GCC versions by scanning the directory rather than using a hard-coded list of versions. This has several benefits. It makes it much more efficient to locate a GCC installation even in the presence of a large number of different options by simply reading the directory once. It also future-proofs us as new GCC versions are released and installed. We no longer have a hard coded list of version numbers, and won't need to manually updated it. We can still filter out known-bad versions as needed. Currently I've left in filtering for all GCC installations prior to 4.1.1, as that was the first one supported previously. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141120 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-04Basic/Diagnostics: Apparently, #pragma ... diagnostic is intended to overrideDaniel Dunbar
the command line options (at least according to GCC's documentation). GCC 4.2 didn't appear to actually do this, but it seems like that has been fixed in later release, so we will follow the docs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141119 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-04Add a comment explaining that I have a better plan for implementing theChandler Carruth
GCC installation search that requires fewer filesystem operations. Planning to implement that next as the current approcah while thorough (and so far looks correct) does a very unfortunate number of filesystem operations. I'm motivated to fix this in no small part because I would like to support a much larger space of triples and GCC versions, which would explode the current algorithm. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141073 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-04Invert the loop for detecting installed GCC trees. This make the loopChandler Carruth
find the newest GCC available, among other goodness. It makes the entire system much less prone to error from prefixes and/or system roots pruning early the set of triples and GCC versions available. Also, improve some comments and simplify the forms of some of the loops. This causes the driver to stat directories more often than is strictly necessary, but the alternatives which I looked at that still accomplished this goal needed quite a bit more code and were likely not much faster. Test cases for this, now that our behavior here is significantly more principled and predictable, should come tomorrow as I walk back through VMs looking for edge cases that are missed after this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141072 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-04Fuse the two halves of the GCC installation detection. This isChandler Carruth
significantly cleaner (IMO) and more principled. We now walk down each layer of the directory hierarchy searching for the GCC install. This change does in fact introduce a significant behavior change in theory, although in practice I don't know of any distro that will be impacted by it negatively, and Debian may (untested) get slightly better through it. Specifically, the logic now looks exhaustively for patterns such as: /usr/lib/<triple>/gcc/<triple> Previously, this would only be selected if there was *also* a '/usr/lib/gcc/<triple>' directory, or if '<triple>' were the excat DefaultHostTriple in the driver. There is a 4-deep nested loop here, but it doesn't do terribly many filesystem operations, as we skip at each layer of that layer's directory doesn't exist. There remains a significant FIXME in this logic: it would be much better to first build up a set of candidate components for each of the four layers with a bottom-up pruning such as this, but then select the final installation using a top-down algorithm in order to find the newest GCC installation available, regardless of which particular path leads to it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141071 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-04Factor the data apart from the logic of locating various GCCChandler Carruth
installations. This first selects a set of prefixes and a set of compatible triples for the current architecture. Once selected, we drive the search with a single piece of code. This code isn't particularly efficient as it stands, but its only executed once. I'm hoping as I clean up the users of this information, it will also slowly become both cleaner and more efficient. This also changes the behavior slightly. Previously, we had an ad-hoc list of prefixes and triples, and we only looked for some triples beneath specific prefixes and vice versa. This has led to lots of one-off patches to support triple X, or support lib dir Y. Even without going to a fully universal driver, we can do better here. This patch makes us always look first in either 'lib32' or 'lib64' on 32- or 64-bit hosts (resp.). However, we *always* look in 'lib'. Currently I have one lingering problem with this strategy. We might find a newer or better GCC version under a different (but equally compatible) triple. Fundamentally, this loop needs to be fused with the one below. That's my next patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141056 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-03Refactor the detection of a GCC installation into a helper class. ThisChandler Carruth
is designed to allow the detection to record more rich information about the installation than just a single path. Mostly, the functionality remains the same. This is primarily a factoring change. However, the new factoring immediately fixes one issue where on ubuntu we didn't walk up enough layers to reach the parent lib path.

2011-10-03Test a multilib setup on a 64-bit host. This is the far more commonChandler Carruth
configuration, although the test still stubs out more directories than are necessary or common in order to exercise all of the lookup paths observed with upstream GCC. This finishes testing the distribution-independent and GCC-installation-independent parts of the library path search logic. More testing is still needed for the triple detection, GCC-installation detection, and handling distributions with unusual configurations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141000 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-03Enable generic multilib support on 32bit hosts. Previously this was onlyChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140999 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-03Relax an assertion here a bit. This doesn't really matter, as we won'tChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140998 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-03Teach the logic for locating an installed GCC about the system root.Chandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140995 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-03Add initial support for applying the sysroot to library search paths.Chandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140990 91177308-0d34-0410-b5e6-96231b3b80d8
