We still don't clean up the lock files when we crash, which is a rather unfortunate problem. I'll handle that next, and there is certainly a *lot* of room for further improvements. llvm-svn: 141179

* Implement the feature I was originally driving toward when I startedChandler Carruth2011-10-054-0/+21
| | | | | | | | | | | | | | 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

* Fix Windows+MinGW which introduces noise into path separators.Chandler Carruth2011-10-041-1/+5
| | | | | | | | | 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. llvm-svn: 141126
* Now that multiple prefixes are much cheaper to search for GCCChandler Carruth2011-10-041-0/+1
| | | | | | | | | | | | | 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. llvm-svn: 141121
* Rework the search for a GCC installation still further. This combinesChandler Carruth2011-10-041-50/+85
| | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 141120

| | | | | | | | InitListChecker::getStructuredSubobjectInit which was increasing the reserved size for an init list past its maximum possible size. Fixes PR11056, a case where we were reserving a bunch of memory for arrays that was never actually used. (No testcase because I don't think we have any way to actually write a testcase for this; the chosen value of NumElements has no effects on anything other than performance and memory usage.) llvm-svn: 141106
