* [ARM] Add support for -sp- FPUs and FPU none to TargetParserJohn Brawn2015-06-051-3/+5
| | | | | | | | | | These are added mainly for the benefit of clang, but this also means that they are now allowed in .fpu directives and we emit the correct .fpu directive when single-precision-only is used. Differential Revision: http://reviews.llvm.org/D10238 llvm-svn: 239151
* [ARM] Add knowledge of FPU subtarget features to TargetParserJohn Brawn2015-06-051-15/+110
| | | | | | | | | | | | | Add getFPUFeatures to TargetParser, which gets the list of subtarget features that are enabled/disabled for each FPU, and use it when handling the .fpu directive. No functional change in this commit, though clang will start behaving differently once it starts using this. Differential Revision: http://reviews.llvm.org/D10237 llvm-svn: 239150

* Simplify ARMTargetParser::getArchSynonymArtyom Skrobov2015-06-042-12/+10
| | | | | | | | | | | | | | | | Summary: 1) The only caller, ARMTargetParser::parseArch, uses the results for an "endswith" test; so, including the "arm" prefix into the result is unnecessary. 2) Most ARMTargetParser::parseArch callers pass it the output from ARMTargetParser::getCanonicalArchName; so, make this behaviour the default. Then, including the "arm" prefix into the cases is unnecessary.

* [ARMTargetParser] Move IAS arch ext parser. NFCRenato Golin2015-05-301-1/+7
| | | | | | | | | | | The plan was to move the whole table into the already existing ArchExtNames but some fields depend on a table-generated file, and we don't yet have this feature in the generic lib/Support side. Once the minimum target-specific table-generated files are available in a generic fashion to these libraries, we'll have to keep it in the ASM parser. llvm-svn: 238651

* [YAMLIO] Make line-wrapping configurable and test it.Frederic Riss2015-05-291-3/+4
| | | | | | | | | | | | | | | | 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.

* ARMTargetParser: Normalising build attributesRenato Golin2015-05-271-18/+22
| | | | | | | | | | | | | | | Now that most of the methods in Clang and LLVM that were parsing arch/cpu/fpu strings are using ARMTargetParser, it's time to make it a bit more conforming with what the ABI says. This commit adds some clarification on what build attributes are accepted and which are "non-standard". It also makes clear that the "defaultCPU" and "defaultArch" methods were really just build attribute getters. It also diverges from GCC's behaviour to say that armv2/armv3 are really an ARMv4 in the build attributes, when the ABI has a clear state for that: Pre-v4. llvm-svn: 238344

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit a 3rd attempt at comitting the initial MIR serialization patch. The first commit (r237708) was reverted in 237730. Then the second commit (r237954) was reverted in r238007, as the MIR library under CodeGen caused a circular dependency where the CodeGen library depended on MIR and MIR library depended on CodeGen. This commit has fixed the dependencies between CodeGen and MIR by reorganizing the MIR serialization code - the code that prints out MIR has been moved to CodeGen, and the MIR library has been renamed to MIRParser. Now the CodeGen library doesn't depend on the MIRParser library, thus the circular dependency no longer exists. --Original Commit Message-- MIR Serialization: print and parse LLVM IR using MIR format. This commit is the initial commit for the MIR serialization project. It creates a new library under CodeGen called 'MIR'.

* Move parseSubArch to ARMTargetParser. NFCRenato Golin2015-05-241-30/+58
| | | | | | | | | | | | Using getCanonicalArchName() is the right way to parse ARM arch names. Mapping ARMTargetParser IDs to Triple Arch IDs is temporary, until they are merged into a TargetDescription class. This was the last LLVM FIXME to move things to ARMTargetParser. Now on to Clang and beyond. llvm-svn: 238110
* Reinforce ARMTargetParser::getCanonicalArchName validationRenato Golin2015-05-221-14/+20
| | | | | | | | | | | | | Before, getCanonicalArchName was relying on parseArch() to validate the arch name, which was a problem when other methods, that also needed to call it, were duplicating the steps. But to dissociate getCanonicalArchName from parseArch, we needed to make getCanonicalArchName more robust in detecting valid arch names. It's still not perfect, but will do for the time being, until we merge Triple with TargetParser into a TargetDescription mega class. llvm-svn: 238047

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit is a 2nd attempt at committing the initial MIR serialization patch. The first commit (r237708) made the incremental buildbots unstable and was reverted in r237730. The original commit didn't add a terminating null character to the LLVM IR source which was passed to LLParser, and this sometimes caused the test 'llvmIR.mir' to fail with a parsing error because the LLVM IR source didn't have a null character immediately after the end and thus LLLexer encountered some garbage characters that ultimately caused the error. This commit also includes the other test fixes I committed in r237712 (llc path fix) and r237723 (remove target triple) which also got reverted in r237730. --Original Commit Message-- MIR Serialization: print and parse LLVM IR using MIR format.

* YAML: Null terminate block scalar's value.Alex Lorenz2015-05-211-1/+2
| | | | | | | | | | | | | 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

* Make Triple::parseARMArch use ARMTargetParserRenato Golin2015-05-212-50/+89

This commit also adds AArch64 detection to ARMTargetParser canonicalization, and a two RedHat arch names (v{6,7}hl, meaning hard-float / little-endian). Adding enough unit tests to cover the basics.

* Get Triple::getARMCPUForArch() to use TargetParserRenato Golin2015-05-202-94/+211
| | | | | | | | | | | | | | | | | | | | First ARMTargetParser FIXME, conservatively changing the way we parse CPUs in the back-end. Still not perfect, with a lot of special cases, but moving towards a more generic solution. Moving all logic to the target parser made some unwritten assumptions about architectures in Clang to break. I've added a lot of architectures required by Clang, and default to CPUs that Clang believes it should (and I agree). I've also added a lot of unit tests, with the correct CPU for each architecture, and Clang seems to be working correctly, too. It also became clear that using "unsigned ID" as the argument for the get methods makes it hard to know what ID, so I also changed the argument names to match the enum type names. llvm-svn: 237797

* [DWARF parser] Add basic support for DWZ DWARF multifile extensions.Alexey Samsonov2015-05-191-0/+4
| | | | | | | | | | | | | | | | | | | | | This change implements basic support for DWARF alternate sections proposal: http://www.dwarfstd.org/ShowIssue.php?issue=120604.1&type=open LLVM tools now understand new forms: DW_FORM_GNU_ref_alt and DW_FORM_GNU_strp_alt, which are used as references to .debug_info and .debug_str sections respectively, stored in a separate file, and possibly shared between different executables / shared objects. llvm-dwarfdump and llvm-symbolizer don't yet know how to access this alternate debug file (usually pointed by .gnu_debugaltlink section), but they can at lease properly parse and dump regular files, which refer to it. This change should fix crashes of llvm-dwarfdump and llvm-symbolizer on files produced by running "dwz" tool. Such files are already installed on some modern Linux distributions. llvm-svn: 237721

* Fix memory leak introduced in r237314.Alex Lorenz2015-05-141-1/+1
| | | | | | | | | | | | | | The commit r237314 that implements YAML block parsing introduced a leak that was caught by the ASAN linux buildbot. YAML Parser stores its tokens in an ilist, and allocates tokens using a BumpPtrAllocator, but doesn't call the destructor for the allocated tokens. R237314 added an std::string field to a Token which leaked as the Token's destructor wasn't called. This commit fixes this leak by calling the Token's destructor when a Token is being removed from an ilist of tokens. llvm-svn: 237389

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 Blaikie2015-05-111-29/+23
| | | | | | | | | | | | 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
* TargetParser: FPU/ARCH/EXT parsing refactory - NFCRenato Golin2015-05-083-1/+200
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new class in a global context contain arch-specific knowledge in order to provide LLVM libraries, tools and projects with the ability to understand the architectures. For now, only FPU, ARCH and ARCH extensions on ARM are supported. Current behaviour it to parse from free-text to enum values and back, so that all users can share the same parser and codes. This simplifies a lot both the ASM/Obj streamers in the back-end (where this came from), and the front-end parsers for command line arguments (where this is going to be used next). The previous implementation, using .def/.h includes is deprecated due to its inflexibility to be built without the backend support and for being too cumbersome. As more architectures join this scheme, and as more features of such architectures are added (such as hardware features, type sizes, etc) into a full blown TargetDescription class, having a set of classes is the most sane implementation. The ultimate goal of this refactor both LLVM's and Clang's target description classes into one unique interface, so that we can de-duplicate and standardise the descriptions, as well as make it available for other front-ends, tools, etc. The FPU parsing for command line options in Clang has been converted to use this new library and a number of aliases were added for compatibility: * A bogus neon-vfpv3 alias (neon defaults to vfp3) * armv5/v6 * {fp4/fp5}-{sp/dp}-d16 Next steps: * Port Clang's ARCH/EXT parsing to use this library. * Create a TableGen back-end to generate this information. * Run this TableGen process regardless of which back-ends are built. * Expose more information and rename it to TargetDescription. * Continue re-factoring Clang to use as much of it as possible. llvm-svn: 236900

This will be used by clang to give an error on invalid -march values. Also restructure the extraction of the architecture version from the MArch string a little to hopefully make what it's doing clearer.

| | | | | | | | | | | | | | | | | | | | | | | | | This commit enables the tests located in test/YAMLParser directory. Those tests were never actually enabled, as llvm-lit didn't pick up the files with the 'data' extension. The commit renames those test files to files with the 'test' extension so that llvm-lit would find them. This commit also modifies yaml-bench so that it returns an error status if an error occurred during parsing. It also adds the '-use-color' command line option to yaml-bench (to make sure that file check matches the error messages in the output stream). This commit modifies some of the renamed tests so that they wouldn't fail. It gets rid of XFAILs and uses the 'not' command instead for some of the tests that have to fail during parsing. This commit also adds some 'FIXME' comments to a couple of tests that are supposed to fail but currently pass because of various bugs in the implementation of the yaml parser.

* [SystemZ] Add z13 vector facility and MC supportUlrich Weigand2015-05-051-0/+24
| | | | | | | | | | | | | | | | | | | | | This patch adds support for the z13 processor type and its vector facility, and adds MC support for all new instructions provided by that facilily. Apart from defining the new instructions, the main changes are: - Adding VR128, VR64 and VR32 register classes. - Making FP64 a subclass of VR64 and FP32 a subclass of VR32. - Adding a D(V,B) addressing mode for scatter/gather operations - Adding 1-, 2-, and 3-bit immediate operands for some 4-bit fields. Until now all immediate operands have been the same width as the underlying field (hence the assert->return change in decode[SU]ImmOperand). In addition, sys::getHostCPUName is extended to detect running natively on a z13 machine. Based on a patch by Richard Sandiford. llvm-svn: 236520
