* Bring in a BumpPtrStringSaver from lld and simplify the interface.Rafael Espindola2015-06-131-9/+4
| | | | | | | | | | | | StringSaver now always saves to a BumpPtrAllocator. The only reason for having the virtual saveImpl is so lld can have a thread safe version. The reason for the distinct BumpPtrStringSaver class is to avoid the virtual destructor. llvm-svn: 239669
* YAML traits need to be in the llvm::yaml namespace.Frederic Riss2015-05-291-8/+8

* [YAMLIO] Make line-wrapping configurable and test it.Frederic Riss2015-05-291-0/+120
| | | | | | | | | | | | | | | | Summary: We would wrap flow mappings and sequences when they go over a hardcoded 70 characters limit. Make the wrapping column configurable (and default to 70 co the change should be NFC for current users). Passing 0 allows to completely suppress the wrapping which makes it easier to handle in tools like FileCheck.

* YAML: Null terminate block scalar's value.Alex Lorenz2015-05-211-0/+12
| | | | | | | | | | | | | The commit null terminates the string value in the `yaml::BlockScalarNode` class. This change is motivated by the initial MIR serialization commit (r237708) that I reverted in r237730 because the LLVM IR source from the block scalar node wasn't terminated by a null character and thus the buildbots failed on one testcase sometimes. This change enables me to recommit the reverted commit. llvm-svn: 237942
* Fix StreamingMemoryObject to respect known object size.Derek Schuff2015-05-211-0/+9
| | | | | | | | | | | | | The existing code for method StreamingMemoryObject.fetchToPos does not respect the corresonding call to setKnownObjectSize(). As a result, it allows the StreamingMemoryObject to read bytes past the object size. This patch provides a test case, and code to fix the problem.

* YAML: Add support for literal block scalar I/O.Alex Lorenz2015-05-141-0/+140
| | | | | | | | | | | | | This commit gives the users of the YAML Traits I/O library the ability to serialize scalars using the YAML literal block scalar notation by allowing them to implement a specialization of the `BlockScalarTraits` struct for their custom types.

* YAML: Implement block scalar parsing.Alex Lorenz2015-05-131-0/+27
| | | | | | | | | | | | | | | | | | | | | This commit implements the parsing of YAML block scalars. Some code existed for it before, but it couldn't parse block scalars. This commit adds a new yaml node type to represent the block scalar values. This commit also deletes the 'spec-09-27' and 'spec-09-28' tests as they are identical to the test file 'spec-09-26'. This commit introduces 3 new utility functions to the YAML scanner class: `skip_s_space`, `advanceWhile` and `consumeLineBreakIfPresent`. Reviewers: Duncan P. N.

* Readdress r236990, use of static members on a non-static variable.David Blaikie2015-05-111-3/+2
| | | | | | | | | | | | The TargetRegistry is just a namespace-like class, instantiated in one place to use a range-based for loop. Instead, expose access to the registry via a range-based 'targets()' function instead. This makes most uses a bit awkward/more verbose - but eventually we should just add a range-based find_if function which will streamline these functions. I'm happy to mkae them a bit awkward in the interim as encouragement to improve the algorithms in time. llvm-svn: 237059

* YAML: Fix crash in the skip method of KeyValueNode class. Alex Lorenz2015-05-061-0/+4
| | | | | | | | | | | | | This commit changes the 'skip' method in the 'KeyValueNode' class to ensure that it doesn't dereference a null pointer when calling the 'skip' method of its value child node. It also adds a unittest that ensures that the crash doesn't occur. This change is motivated by a patch that implements parsing of YAML block scalars (http://reviews.llvm.org/D9503), as one of the unittests in that patch triggered this problem. llvm-svn: 236669

* Fix infinite recursion in ScaledNumber::toInt.Diego Novillo2015-05-011-0/+5
| | | | | | | | | Patch from dexonsmith. The call to toInt() was calling compareTo() which in some cases would call back to toInt(), creating an infinite loop. Fixed by simplifying the logic in compareTo() to avoid the co-recursion. llvm-svn: 236326
* Fix private constructor for ScaledNumber.Diego Novillo2015-04-301-0/+24
| | | | | | | | | | | | | | | | | | | | | | | Summary: The private constructor for ScaledNumber was using uint64_t instead of DigitsT. This was preventing instantiations of ScaledNumber with anything other than uint64_t types. In implementing the tests, I ran into another issue. Operators >>= and <<= did not have variants for accepting other ScaledNumber as the shift argument. This is expected by the SCALED_NUMBER_BOP. It makes no sense to allow shifting a ScaledNumber by another ScaledNumber, so the patch includes two new templates for shifting ScaledNumbers.

* Don't allow pwrite to resize a stream.Rafael Espindola2015-04-201-1/+9
| | | | | | | | | | | | | | | | | | | | | The current implementations could exhibit some behavior differences: raw_fd_ostream: Whatever the underlying fd does with seek+write. In a normal file, the write position would be back to the old offset. raw_svector_ostream: The write position is always the end of the stream, so after pwrite the write position would be the new end. This matches what OS_X (all BSD?) do with a pwrite in a O_APPEND fd. Given that we don't need that feature and don't use O_APPEND a lot in LLVM, just disallow it. I am open to suggestions on renaming pwrite to something else, but this fixes the issue for now. Thanks to Yaron Keren for reporting it. llvm-svn: 235303
* Add raw_pwrite_stream type.Rafael Espindola2015-04-142-0/+26

* Detect malformed YAML sequence in yaml::Input::beginSequence()Justin Bogner2015-03-021-0/+86
| | | | | | | | | | | | | | | | | | | | | When reading a yaml::SequenceTraits object, YAMLIO does not report an error if the yaml item is not a sequence. Instead, YAMLIO reads an empty sequence. For example: --- seq: foo: 1 bar: 2 ... If `seq` is a SequenceTraits object, then reading the above yaml will yield `seq` as an empty sequence. Fix this to report an error for the above mapping ("not a sequence") Patch by William Fisher. Thanks! llvm-svn: 230976

This is needed to implement a proper support for -fsanitize-blacklist flag (allow users to specify multiple blacklists, in addition to default blacklist, see PR22431). DFSan can also benefit from this change, as DFSan instrumentation pass now accepts ABI-lists both from -fsanitize-blacklist= and -mllvm -dfsan-abilist flags. Go bindings are fixed accordingly.

* Refactoring llvm command line parsing and option registration.Chris Bieneman2015-01-281-7/+5
| | | | | | | | | | | | | | | | | | | | | Summary: The primary goal of this patch is to remove the need for MarkOptionsChanged(). That goal is accomplished by having addOption and removeOption properly sort the options. This patch puts the new add and remove functionality on a CommandLineParser class that is a placeholder. Some of the functionality in this class will need to be merged into the OptionRegistry, and other bits can hopefully be in a better abstraction. This patch also removes the RegisteredOptionList global, and the need for cl::Option objects to be linked list nodes. The changes in CommandLineTest.cpp are required because these changes shift when we validate that options are not duplicated. Before this change duplicate options were only found during certain cl API calls (like cl::ParseCommandLine). With this change duplicate options are found during option construction.
