2010-08-20Delete SlowOperationInformer, which is no longer used.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111661 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Make outs() close its file when its stream is destructed, so thatDan Gohman
pending output errors are detected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111643 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Delete raw_stdout_ostream and raw_stderr_ostream, which are unusedDan Gohman
outside of outs() and errs() themselves, and they don't really need custom classes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111642 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Move raw_ostream's Error flag into raw_fd_ostream, as that's the onlyDan Gohman
class which is using it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111639 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Introduce a new tool_output_file class, which extends raw_ostream withDan Gohman
functionality that most command-line tools need: ensuring that the output file gets deleted if the tool is interrupted or encounters an error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111595 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-19Do not assert when reading an exponent out of range.Dale Johannesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111534 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-18Make raw_fd_ostream consider itself the owner of STDOUT_FILENO whenDan Gohman
constructed with an output filename of "-". In particular, allow the file descriptor to be closed, and close the file descriptor in the destructor if it hasn't been explicitly closed already, to ensure that any write errors are detected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111436 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-18Revert r111321. This doesn't fix a problem.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111339 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111337 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-17include config.h to get config params, hopefully unbreaking mingw builder.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111325 91177308-0d34-0410-b5e6-96231b3b80d8
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

2010-08-16Add 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

with FoldingSetTrait::Profile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111127 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

2010-06-30Rather 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

2010-06-25Tweak MemoryBuffer to allocate the class itself, the name and possibly theBenjamin Kramer
