* MIR Serialization: Connect the machine function analysis pass to the MIR parser.Alex Lorenz2015-06-151-22/+24
| | | | | | | | | | | | | | | | | | | | | This commit connects the machine function analysis pass (which creates machine functions) to the MIR parser, which will initialize the machine functions with the state from the MIR file and reconstruct the machine IR. This commit introduces a new interface called 'MachineFunctionInitializer', which can be used to provide custom initialization for the machine functions. This commit also introduces a new diagnostic class called 'DiagnosticInfoMIRParser' which is used for MIR parsing errors. This commit modifies the default diagnostic handling in LLVMContext - now the the diagnostics are printed directly into llvm::errs() so that the MIR parsing errors can be printed with colours.

* Don't use std::errc.Rafael Espindola2015-06-132-3/+5
| | | | | | | | | | | | | | | | | | | | | As noted on Errc.h: // * std::errc is just marked with is_error_condition_enum. This means that // common patters like AnErrorCode == errc::no_such_file_or_directory take // 4 virtual calls instead of two comparisons. And on some libstdc++ those virtual functions conclude that ------------------------ int main() { std::error_code foo = std::make_error_code(std::errc::no_such_file_or_directory); return foo == std::errc::no_such_file_or_directory; } ------------------------- should exit with 0. llvm-svn: 239683
* Bring in a BumpPtrStringSaver from lld and simplify the interface.Rafael Espindola2015-06-133-28/+30
| | | | | | | | | | | | 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
* Add 'shave' processor name to TripleDouglas Katzman2015-06-121-0/+7
| | | | | | | | | | Based on ArchType, Clang's driver can select a non-Clang compiler. String parsing in Clang would have sufficed if it were only that, however this change anticipates true llvm support. Differential Revision: http://reviews.llvm.org/D10413 llvm-svn: 239631
* [ARM] Disabling vfp4 should disable fp16John Brawn2015-06-121-1/+5
| | | | | | | | | | | ARMTargetParser::getFPUFeatures should disable fp16 whenever it disables vfp4, as otherwise something like -mcpu=cortex-a7 -mfpu=none leaves us with fp16 enabled (though the only effect that will have is a wrong build attribute).

* [Support] Fix a race initializing a static local in MSVCReid Kleckner2015-06-111-1/+9
| | | | | | | | | static local initialization isn't thread safe with MSVC and a race was reported in PR23817. We can't use std::atomic because it's not trivially constructible, so instead do some lame volatile global integer manipulation. llvm-svn: 239566

* [ADT] Assert that SmallVectorBase::grow_pod() successfully reallocates memory.Daniel Sanders2015-06-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | Summary: If malloc/realloc fails then the SmallVector becomes unusable since begin() and end() will return NULL. This is unlikely to occur but was the cause of recent bugpoint test failures on my machine. It is not clear whether not checking for malloc/realloc failure is a deliberate decision and adding checks has the potential to impact compiler performance. Therefore, this patch only adds the check to builds with assertions enabled for the moment.

* 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

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.

* 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

* 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

* 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
