2010-08-18Revert r111321. This doesn't fix a problem.Dan Gohman

2010-08-17Fix the rest of rdar://8318441 which happens when a raw_fd_ostreamChris Lattner
(e.g. errs()) fails in close() due to (e.g.) a broken pipe. As previously written, the had_error() flag would get set and then the raw_ostream dtor would report a fatal error. There is nothing the client can do about this and we have no way to report the error, so just eat it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111321 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-17report_fatal_error can't use errs(), because errs() can call Chris Lattner
into report_fatal_error. Just blast the string to stderr with write(2) and hope for the best! Part of rdar://8318441 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111320 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-17CrashRecovery: Clear the current context on the first crash, to avoid ↵Daniel Dunbar
re-entering it if the cleanup code crashes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111309 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-16Add hooks to FoldingSetTrait to allow specializations to provideDan Gohman
implementations of equality comparison and hash computation. This can be used to optimize node lookup by avoiding creating lots of temporary ID values just for hashing and comparison purposes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111130 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-12Add a 'normalize' method to the Triple class, which takes a mucked upDuncan Sands
target triple and straightens it out. This does less than gcc's script config.sub, for example it turns i386-mingw32 into i386--mingw32 not i386-pc-mingw32, but it does a decent job of turning funky triples into something that the rest of the Triple class can understand. The plan is to use this to canonicalize triple's when they are first provided by users, and have the rest of LLVM only deal with canonical triples. Once this is done the special case workarounds in the Triple constructor can be removed, making the class more regular and easier to use. The comments and unittests for the Triple class are already adjusted in this patch appropriately for this brave new world of increased uniformity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110909 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-29CrashRecoveryContext: Add a simple POSIX implementation.Daniel Dunbar
- This works, but won't handle crashes on stack overflow, or signals delivered to a thread other than the one that crashed. The latter is particular annoying on Darwin, because SIGABRT tends to go to the main thread. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109717 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-28Support: Add CrashRecoveryContext helper object.Daniel Dunbar
- Designed as a simple wrapper to allow clients to attempt to catch crashes (memory errors, assertion violations, etc.) and do some kind of recovery. - Currently doesn't actually attempt to catch crashes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109586 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-30Rather than giving SmallPtrSetImpl a member field SmallArray which is magicallyDuncan Sands
replaced by a bigger array in SmallPtrSet (by overridding it), instead just use a pointer to the start of the storage, and have SmallPtrSet pass in the value to use. This has the disadvantage that SmallPtrSet becomes bigger by one pointer. It has the advantage that it no longer uses tricky C++ rules, and is clearly correct while I'm not sure the previous version was. This was inspired by g++-4.6 pointing out that SmallPtrSetImpl was writing off the end of SmallArray, which it was. Since SmallArray is replaced with a bigger array in SmallPtrSet, the write was still to valid memory. But it was writing off the end of the declared array type - sounds kind of dubious to me, like it sounded dubious to g++-4.6. Maybe g++-4.6 is wrong and this construct is perfectly valid and correctly compiled by all compilers, but I think it is better to avoid the whole can of worms by avoiding this construct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107285 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-25Bring back the empty vector workaround I removed in r106839. Looks like MSVC ↵Benjamin Kramer

2010-06-25Tweak MemoryBuffer to allocate the class itself, the name and possibly theBenjamin Kramer
buffer in the same chunk of memory. 2 less mallocs for every uninitialized MemoryBuffer and 1 less malloc for every MemoryBuffer pointing to a memory range translate into 20% less mallocs on clang -cc1 -Eonly Cocoa_h.m. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106839 91177308-0d34-0410-b5e6-96231b3b80d8
