2015-01-11Basic: [asmSymbolicName] follows the same rule as numbers in asm inputsDavid Majnemer1-0/+4
Input constraints like "0" and "[foo]" should be treated the same when it comes to their corresponding output constraint. This fixes PR21850. llvm-svn: 225605

2015-01-06Sema: analyze I,J,K,M,N,O constraintsSaleem Abdulrasool2-0/+57
Add additional constraint checking for target specific behaviour for inline assembly constraints. We would previously silently let all arguments through for these constraints. In cases where the constraints were violated, we could end up failing to select instructions and triggering assertions or worse, silently ignoring instructions. llvm-svn: 225244

2014-12-18Make sure that arm-linux-gnu is still the apcs-gnu ABI when weEric Christopher1-0/+3
use clang -cc1 matching the front end and backend. Fix up a couple of tests that were testing aapcs for arm-linux-gnu. The test that removes the aapcs abi calling convention removes them because the default triple matches what the backend uses for the calling convention there and so it doesn't need to be explicitly stated - see the code in TargetInfo.cpp. llvm-svn: 224491
2014-12-17Destroy the diagnostic client first in ~DiagnosticEngineReid Kleckner1-0/+6
Add a comment and a test to ~DiagnosticEngine about the ordering requirements on the teardown of DiagnosticConsumer. This could also be accomplished by rearranging the fields of ~DiagnosticEngine, but I felt that this was a better, more explicit solution. This fixes PR21911, an issue that occurred after the unique_ptr migration in r222193. llvm-svn: 224454
2014-12-17[mips] Always clobber $1 for MIPS inline asm.Toma Tabacu1-2/+1
Summary: Because GCC doesn't use $1 for code generation, inline assembly code can use $1 without having to add it to the clobbers list. LLVM, on the other hand, does not shy away from using $1, and this can cause conflicts with inline assembly which assumes GCC-like code generation. A solution to this problem is to make Clang automatically clobber $1 for all MIPS inline assembly. This is not the optimal solution, but it seems like a necessary compromise, for now.

2014-12-10cmake: Make SVNVersion.inc step depend on GetSVN.cmake.Nico Weber1-2/+4
This way, the step generating SVNVersion.inc gets rerun every time someone changes GetSVN.cmake (which is the file that decides how the contents of SVNVersion.inc look). This makes hacking on GetSVN.cmake a bit easier. llvm-svn: 223861
2014-12-09Re-work the Clang system for classifying Intel x86 CPUs to use theirChandler Carruth1-38/+71
basic microarchitecture names, and add support (with tests) for parsing all of the masic microarchitecture names for CPUs documented to be accepted by GCC with -march. I didn't go back through the 32-bit-only old microarchitectures, but this at least brings the recent architecture names up to speed. This is essentially the follow-up to the LLVM commit r223769 which did similar cleanups for the LLVM CPUs. One particular benefit is that you can now use -march=westmere in Clang and get the LLVM westmere processor which is a different ISA variant (!) and so quite significant. Much like with r223769, I would appreciate the Intel folks carefully thinking about the macros defined, names used, etc for the atom chips and newest primary x86 chips. The current patterns seem quite strange to me, especially here in Clang. Note that I haven't replicated the per-microarchitecture macro defines provided by GCC. I'm really opposed to source code using these rather than using ISA feature macros. llvm-svn: 223776

2014-12-02Emit warning if define or undef reserved identifier or keyword.Serge Pavlov1-2/+27
Summary: This change implements warnings if macro name is identical to a keyword or reserved identifier. The warnings are different depending on the "danger" of the operation. Defining macro that replaces a keyword is on by default. Other cases produce warning that is off by default but can be turned on using option -Wreserved-id-macro. This change fixes PR11488.

2014-12-02[modules] Track how 'header' directives were written in module map files,Richard Smith1-12/+13
rather than trying to extract this information from the FileEntry after the fact. This has a number of beneficial effects. For instance, diagnostic messages for failed module builds give a path relative to the "module root" rather than an absolute file path, and the contents of the module includes file is no longer dependent on what files the including TU happened to inspect prior to triggering the module build. llvm-svn: 223095

2014-11-20[CMake] Use .svn/wc.db as our VC dependency if it's available.Jordan Rose1-6/+10
In order to keep SVNVersion.inc from being regenerated on every build, we need to specify as a dependency a file that only changes when the VC state updates. I previously just had .svn/entries, but that's only used by Subversion 1.6. 1.7 uses .svn/wc.db instead; prefer that if it's present. (Thanks, Nico!) llvm-svn: 222407
2014-11-19[CMake] Always include the Clang repo version, just like the autoconf build.Jordan Rose1-25/+43
Now that LLVM's helper script GetSVN.cmake actually works consistently, there's no reason not to use it. We avoid having to regenerate SVNVersion.inc every time by marking it as dependent on Git's reflog or SVN's entries file. This should end most of the issues of the AST format changing and breaking old module files: CMake-Clang should now detect that the version changed just like Autoconf-Clang has. Based on r190557.

2014-11-11[Sanitizer] Refactor sanitizer options in LangOptions.Alexey Samsonov3-18/+33
Get rid of ugly SanitizerOptions class thrust into LangOptions: * Make SanitizeAddressFieldPadding a regular language option, and rely on default behavior to initialize/reset it. * Make SanitizerBlacklistFile a regular member LangOptions. * Introduce the helper class "SanitizerSet" to represent the set of enabled sanitizers and make it a member of LangOptions. It is exactly the entity we want to cache and modify in CodeGenFunction, for instance. We'd also be able to reuse SanitizerSet in CodeGenOptions for storing the set of recoverable sanitizers, and in the Driver to represent the set of sanitizers turned on/off by the commandline flags. No functionality change. llvm-svn: 221653
2014-11-07Introduce a SanitizerKind enum to LangOptions.Alexey Samsonov2-5/+13
Use the bitmask to store the set of enabled sanitizers instead of a bitfield. On the negative side, it makes syntax for querying the set of enabled sanitizers a bit more clunky. On the positive side, we will be able to use SanitizerKind to eventually implement the new semantics for -fsanitize-recover= flag, that would allow us to make some sanitizers recoverable, and some non-recoverable.

missing checks to test for target features. This patch simplifies how default target features are set for AMD bdver2 and bdver1. In particular, method 'getDefaultFeatures' now implements a fallthrough from case 'CK_BDVER2' to case 'CK_BDVER1'. That is because 'bdver2' has the same features available in bdver1 plus BMI, FMA, F16C and TBM. This patch also adds missing checks for predefined macros in test predefined-arch-macros.c. In the case of BTVER2, the test now also checks for F16C, BMI and PCLMUL. In the case of BDVER3 and BDVER4, the test now also checks for the presence of FSGSBASE.
