* [lit] Fix bug when using Python3 where a failing test would not showDan Liew2015-11-191-1/+3
| | | | | | | | | | | | | | | | the script when running a ShTest with an external or internal shell. This bug is caused by use of the ``map`` function in Python 3 which returns an iterable (rather than a list in Python 2). After the iterable is exhausted it won't return any more output and consequently when ``_runShTest()`` tries to access the ``script`` which has already been iterated over it is empty. Converting to a list immediatley after calling ``map()`` fixes this. This fixes the ``tests/shtest-format.py`` test when running under Python3 which was previously failing. llvm-svn: 253556
* Default SetVector to use a DenseSet.Rafael Espindola2015-11-182-5/+5
| | | | | | | | | | | | | | | We use to have an odd difference among MapVector and SetVector. The map used a DenseMop, but the set used a SmallSet, which in turn uses a std::set. I have changed SetVector to use a DenseSet. If you were depending on the old behaviour you can pass an explicit set type or use SmallSetVector. The common cases for needing to do it are: * Optimizing for small sets. * Sets for types not supported by DenseSet. llvm-svn: 253439

* Assume lane masks are always preciseMatthias Braun2015-11-171-13/+6
| | | | | | | | | | | | | | | Allowing imprecise lane masks in case of more than 32 sub register lanes lead to some tricky corner cases, and I need another bugfix for another one. Instead I rather declare lane masks as precise and let tablegen abort if we do not have enough bits. This does not affect any in-tree target, even AMDGPU only needs 16 lanes at the moment. If the 32 lanes turn out to be a problem in the future, then we can easily change the LaneBitmask typedef to uint64_t. Differential Revision: http://reviews.llvm.org/D14557 llvm-svn: 253279
* [MCTargetAsmParser] Move the member varialbes that referenceAkira Hatanaka2015-11-141-1/+1

* [lit] Fix bug where ``lit.util.which()`` would return a directoryDan Liew2015-11-131-1/+1
| | | | | | | | | | | | | | | | | instead of executable if the argument was found inside a directory contained in PATH. An example where this could cause a problem is if there was a RUN line that ran the ``test`` command and if the user had a directory in their PATH that contained a directory called ``test/`` (that occured before ``/usr/bin/``). Lit would try to use the directory as the executable which would fail with the rather cryptic message. ``` Could not create process due to [Errno 13] Permission denied ``` llvm-svn: 253031

| | | | | | | | | | | | | | | | | | This reapplies r252949. I've changed the type of FuncName to be std::string instead of StringRef in emitFnAttrCompatCheck.

* Move the enum attributes defined in Attributes.h to a table-gen file.Akira Hatanaka2015-11-114-1/+68
| | | | | | | | | | | | | | This is a step towards consolidating some of the information regarding attributes in a single place. This patch moves the enum attributes in Attributes.h to the table-gen file. Additionally, it adds definitions of target independent string attributes that will be used in follow-up commits by the inliner to check attribute compatibility. rdar://problem/19836465 llvm-svn: 252796

* [lit] Raise the default soft process limit when possibleHal Finkel2015-10-021-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | It is common to have a default soft process limit, at least on some families of Linux distributions, of 1024. This is normally more than enough, but if you have many cores, and you're running tests that create many threads, this can become a problem. My POWER7 development machine has 48 cores, and when running the lld regression tests, which often want to create up to 48 threads, I run into problems. lit, by default, will want to run 48 tests in parallel, and 48*48 < 1024, and so many tests fail like this: terminate called after throwing an instance of 'std::system_error' what(): Resource temporarily unavailable or lit fails like this when launching a test: OSError: [Errno 11] Resource temporarily unavailable lit can easily detect this situation and attempt to repair it before launching tests (by raising the soft process limit to something that will allow ncpus^2 threads to be created), and should do so to prevent spurious test failures.

* [WinEH] Make FuncletLayout more robust against catchretDavid Majnemer2015-10-011-3/+3
| | | | | | | | | Catchret transfers control from a catch funclet to an earlier funclet. However, it is not completely clear which funclet the catchret target is part of. Make this clear by stapling the catchret target's funclet membership onto the CATCHRET SDAG node. llvm-svn: 249052
* HHVM calling conventions.Maksim Panchenko2015-09-291-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | HHVM calling convention, hhvmcc, is used by HHVM JIT for functions in translated cache. We currently support LLVM back end to generate code for X86-64 and may support other architectures in the future. In HHVM calling convention any GP register could be used to pass and return values, with the exception of R12 which is reserved for thread-local area and is callee-saved. Other than R12, we always pass RBX and RBP as args, which are our virtual machine's stack pointer and frame pointer respectively. When we enter translation cache via hhvmcc function, we expect the stack to be aligned at 16 bytes, i.e. skewed by 8 bytes as opposed to standard ABI alignment. This affects stack object alignment and stack adjustments for function calls. One extra calling convention, hhvm_ccc, is used to call C++ helpers from HHVM's translation cache. It is almost identical to standard C calling convention with an exception of first argument which is passed in RBP (before we use RDI, RSI, etc.) Differential Revision: http://reviews.llvm.org/D12681 llvm-svn: 248832

| | | | | | | | | | file. Additionally const correct a couple static array. Previously the code added an extra nullptr entry to a static array and then created an ArrayRef with a size one less than the static array. If there were no other entries the array would just contain the nullptr and the ArrayRef would be crated with size 0. Instead, put the right number of entries in the array and explicitly emit 'None' if the size would be 0. This allows the static array constructor of makeArrayRef to be used. llvm-svn: 248244

* Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* ↵Daniel Sanders2015-09-151-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | and related. NFC. Summary: This is the first patch in the series to migrate Triple's (which are ambiguous) to TargetTuple's (which aren't). For the moment, TargetTuple simply passes all requests to the Triple object it holds. Once it has replaced Triple, it will start to implement the interface in a more suitable way. This change makes some changes to the public C++ API. In particular, InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer() now take TargetTuples instead of Triples. The other public C++ API's have been left as-is for the moment to reduce patch size. This commit also contains a trivial patch to clang to account for the C++ API change.
