* [raw_ostream] Raise some helper functions out of raw_ostream.Zachary Turner2016-10-113-137/+200
| | | | | | | | | | Low level functionality to format numbers were embedded in the implementation of raw_ostream. I have need to use these through an interface other than the overloaded stream operators, so they need to be raised to a level that they can be used from either raw_ostream operators or other code. llvm-svn: 283921
* [Support] Fix undefined behavior in RandomNumberGenerator.Zachary Turner2016-10-111-4/+4
| | | | | | | | | This has existed pretty much forever AFAICT, but the code was never being exercised because nobody was using the class. A user of this class surfaced, and now we're breaking with UB. The code was obviously wrong, so it's fixed here. llvm-svn: 283912
* [cl] Don't print subcommand help when no subcommands present.Zachary Turner2016-10-111-4/+6
| | | | | | | | | | | | | | | | Previously we would print USAGE: <exe> [subcommand] [options] Even if no subcommands were present. This changes the output format to only print "[subcommand]" if there is at least one subcommand. Fixes llvm.org/pr30598 Patch by Serge Guelton llvm-svn: 283892

* [Support][CommandLine] Add cl::getRegisteredSubcommands()Dean Michael Berris2016-10-051-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | This should allow users of the library to get a range to iterate through all the subcommands that are registered to the global parser. This allows users to define subcommands in libraries that self-register to have dispatch done at a different stage (like main). It allows for writing code like the following: for (auto *S : cl::getRegisteredSubcommands()) { if (*S) { // Dispatch on S->getName(). } } This change also contains tests that show this usage pattern.

* Statistic: Only print statistics on exit for -statsMatthias Braun2016-09-261-8/+9
| | | | | | | | | | | | | | | Previously enabling the statistics with EnableStatistics() would lead to them getting printed to stderr/-info-output-file on exit. However frontends may want a way to enable statistics and do the printing on their own instead of the forced printing on exit. This changes the code so that only the -stats option enables printing on exit, EnableStatistics() only enables the tracking but requires invoking one of the PrintStatistics() variants.

* Triple: Add opencl environment typeTom Stellard2016-09-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: For AMDGPU, we have been using the operating system component of the triple for specifying the low-level runtime that is being used. The rationale for this is that the host operating system (e.g. Linux) is irrelevant for GPU code, since its execution enviroment will be mostly controled by the low-level runtime being used to execute the code. In most cases, higher level languages have their own runtime which is implemented on top of the low-level runtime. The kernel ABIs of each language mostly depend on the low-level runtime, but there may be some slight differences between languages. OpenCL for example, may append additional arguments to the kernel in order to pass values like global offsets or buffers for printf. OpenMP, HCC, or other languages may want to add their own values which differ from OpenCL. The reason for adding a new opencl environment type is to make it possible for the backend to distinguish between the ABIs of the higher-level languages and handle them correctly. It seems cleaner to use the enviroment component for this rather than creating a new OS type for every combination of low-level runtime / high-level language.

* Speculative fix for build failures due to consumeInteger.Zachary Turner2016-09-221-0/+3
| | | | | | | | | | | | | | | | A recent patch added support for consumeInteger() and made getAsInteger delegate to this function. A few buildbots are failing as a result with an assertion failure. On a hunch, I tested what happens if I call getAsInteger() on an empty string, and sure enough it crashes the same way that the buildbots are crashing. I confirmed that getAsInteger() on an empty string did not crash before my patch, so I suspect this to be the cause. I also added a unit test for the empty string. llvm-svn: 282170
* [Support] Add StringRef::consumeInteger.Zachary Turner2016-09-221-25/+55
| | | | | | | | | | | | | | | | | | | | | StringRef::getInteger() exists and treats the entire string as an integer of the specified radix, failing if any invalid characters are encountered or the number overflows. Sometimes you might have something like "123456foo" and you want to get the number 123456 and leave the string "foo" remaining. This is similar to what would be possible by using the standard runtime library functions strtoul et al and specifying an end pointer. This patch adds consumeInteger(), which does exactly that. It consumes as much as possible until an invalid character is found, and modifies the StringRef in place so that upon return only the portion of the StringRef after the number remains.

* ADT: Add AllocatorList, and use it for yaml::TokenDuncan P. N. Exon Smith2016-09-111-18/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add AllocatorList, a non-intrusive list that owns an LLVM-style allocator and provides a std::list-like interface (trivially built on top of simple_ilist), - add a typedef (and unit tests) for BumpPtrList, and - use BumpPtrList for the list of llvm::yaml::Token (i.e., TokenQueueT). TokenQueueT has no need for the complexity of an intrusive list. The only reason to inherit from ilist was to customize the allocator. TokenQueueT was the only example in-tree of using ilist<> in a truly non-intrusive way. Moreover, this removes the final use of the non-intrusive ilist_traits<>::createNode (after r280573, r281177, and r281181). I have a WIP patch that removes this customization point (and the API that relies on it) that I plan to commit soon. Note: AllocatorList owns the allocator, which limits the viable API (e.g., splicing must be on the same list). For now I've left out any problematic API. It wouldn't be hard to split AllocatorList into two layers: an Impl class that calls DerivedT::getAlloc (via CRTP), and derived classes that handle Allocator ownership/reference/etc semantics; and then implement splice with appropriate assertions; but TBH we should probably just customize the std::list allocators at that point. llvm-svn: 281182
* Add a lower level zlib::uncompress.Rafael Espindola2016-09-091-6/+13
| | | | | | | | | | | SmallVectors are convenient, but they don't cover every use case. In particular, they are fairly large (3 pointers + one element) and there is no way to take ownership of the buffer to put it somewhere else. This patch then adds a lower lever interface that works with any buffer. llvm-svn: 281082
* Add an c++ itanium demangler to llvm.Rafael Espindola2016-09-062-8/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a copy of the demangler in libcxxabi. The code also has no dependencies on anything else in LLVM. To enforce that I added it as another library. That way a BUILD_SHARED_LIBS will fail if anyone adds an use of StringRef for example. The no llvm dependency combined with the fact that this has to build on linux, OS X and Windows required a few changes to the code. In particular: No constexpr. No alignas On OS X at least this library has only one global symbol: __ZN4llvm16itanium_demangleEPKcPcPmPi My current plan is: Commit something like this Change lld to use it Change lldb to use it as the fallback Add a few #ifdefs so that exactly the same file can be used in libcxxabi to export abi::__cxa_demangle. Once the fast demangler in lldb can handle any names this implementation can be replaced with it and we will have the one true demangler. llvm-svn: 280732

* Fix a real temp file leak in FileOutputBufferReid Kleckner2016-09-021-0/+3
| | | | | | | | | | | | | If we failed to commit the buffer but did not die to a signal, the temp file would remain on disk on Windows. Having an open file mapping and file handle prevents the file from being deleted. I am choosing not to add an assertion of success on the temp file removal, since virus scanners and other environmental things can often cause removal to fail in real world tools. Also fix more temp file leaks in unit tests. llvm-svn: 280445

* ADT: Split ilist_node_traits into alloc and callback, NFCDuncan P. N. Exon Smith2016-08-301-9/+2
| | | | | | | | | | | | | | | | Many lists want to override only allocation semantics, or callbacks for iplist. Split these up to prevent code duplication. - Specialize ilist_alloc_traits to change the implementations of deleteNode() and createNode(). - One common desire is to do nothing deleteNode() and disable createNode(). Specialize ilist_alloc_traits to inherit from ilist_noalloc_traits for that behaviour. - Specialize ilist_callback_traits to use the addNodeToList(), removeNodeFromList(), and transferNodesFromList() callbacks. As a drive-by, add some coverage to the callback-related unit tests. llvm-svn: 280128
