* Move a bunch of tests to directly use the CC1 layer. This at least savesChandler Carruth2014-01-156-7/+7
| | | | | | | | | | | a subprocess invocation which is pretty significant on Windows. It also likely saves a bunch of thrashing the host machine needlessly. Finally it makes the tests much more predictable and less dependent on the host. For example 'header_lookup1.c' was passing '-fno-ms-extensions' just to thwart the host detection adding it into the compilation. By runnig CC1 directly we don't have to deal with such oddities. llvm-svn: 199308
* Switch this test from needlessly running the clang driver to directlyChandler Carruth2014-01-151-1/+1
| | | | | | | | | | | | | | | | | | | | | test the CC1 layer. This actually uncovered that the test semes to no longer be passing for the reasons intended. =[ The name of the test would lead me to believe that it should be testing the semantics of noreturn in the static analyzer.... but there are in fact no -verify assertions about noreturn that i can find. And the noreturn checker is no longer in 'alpha.core'. It is in 'core.builtins'. The test *does* have one assertion for a null dereference warning. This *also* isn't in 'alpha.core', but the driver inserts a pile of other checker packages, including 'core' which has this warning. So I have switch the RUN line to actually do the minimal thing that this test currently exercises, but someone who works on the static analyzer should probably look at this and either nuke it or move it to actually check the noreturn behavior. llvm-svn: 199307

* CodeGen: Simplify CodeGenFunction::EmitCaseStmtJustin Bogner2014-01-153-52/+0
| | | | | | | | | | | | | Way back in r129652 we tried to avoid emitting an empty block at -O0 for switch cases that did nothing but break. This led to a poor debugging experience as reported in PR9796, so we disabled the optimization for -O0 but left it in for higher optimization levels in r154420. Since the whole point of this was to improve -O0, it's silly to keep the complexity at all. llvm-svn: 199302
* Fix the attribute enable_if example in the docs to be 100% real-world, ↵Nick Lewycky2014-01-151-1/+3
| | | | | | instead of merely being close to the real world to mislead people. This now matches the test. llvm-svn: 199298
* Fix cxx_variable_templates feature check and documentationAlp Toker2014-01-152-2/+1
| | | | | | | | | | This C++ feature has been marked complete since r191549, but the documentation claimed it wasn't supported at all and the extension check misreported it as being available in C. No regression test; this was a short-lived typo. llvm-svn: 199292
* Fixed error recovery if sizeof is used without parenthesisSerge Pavlov2014-01-153-2/+19
| | | | | | | | | | | Changes made in r192200 fixed PR16992, which requested fixit suggesting parenthesis if sizeof is followed by type-id. However expression in form T() followed by ')' was incorrectly considered as a type-id if 'T' is typedef name. This change fixes this case.

* lit.cfg: Don't expand %ms_abi_triple to non-X86 triplesHans Wennborg2014-01-151-9/+9
| | | | | | | | This is a follow-up to r199260. On ARM hosts, we were attempting to run tests with triples such as armv7l-unknown-win32. This expands that fix to cover all non-x86 targets since we only support MS ABI on x86. llvm-svn: 199280

* Driver: clarify help string for "-###"Tim Northover2014-01-142-2/+2
| | | | | | | | | | | | Someone recently wasted some time not realising that "-###" didn't actually execute the commands it printed, and suggested a documentation tweak. Having made the same mistake myself on at least one occasion, I sympathise. So here it is. Any kibitzing on an even better text welcome. llvm-svn: 199256

* Remove the -cxx-abi command-line flag.Hans Wennborg2014-01-14213-341/+335
| | | | | | | | | | | | | | | This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

* Darwin: add __sinpi (etc) and __exp10 libbuiltinsTim Northover2014-01-142-1/+35
| | | | | | | | | | | These functions have the same constness properties of the normal libm functions, which allows LLVM to optimise code better in general. There are also a couple of specific optimisations that only trigger when these are properly marked. rdar://problem/13729466 llvm-svn: 199249
* Clarify driver/frontend -fms-compatibility help textAlp Toker2014-01-141-2/+2
| | | | | | | | | | | | Better describe the flag that enables drop-in MSVC compatibility, including ability to parse MS standard headers. This is intended to distinguish it from -fms-extensions, the more established and 'gentler' flag also supported by GCC. The new wording matches up with the internal description introduced in r198936. Still room for improvement (e.g. C++ is part of the product name, yet the flag also applies to C) but it's a step forward from "Microsoft mode". llvm-svn: 199247

* Simplifying the OpenCL image attribute. It does not need a semantic integer ↵Aaron Ballman2014-01-147-112/+22
| | | | | | parameter because the required information is encoded in the spelling. Added an appropriate subject to the attribute, and simplified the semantic checking (which will likely be expanded upon in a future patch). Also, removed the GNU spelling since it was unsupported in the first place. llvm-svn: 199229

* [analyzer] Use synthesized ASTs for property getters when available.Jordan Rose2014-01-142-12/+24
| | | | | | | This allows the analyzer to handle properties with C++ class type, finishing up the FIXME from r198953. llvm-svn: 199226
* Use a proper lvalue-to-rvalue conversion in Objective-C++ property accessors.Jordan Rose2014-01-141-4/+10
| | | | | | | | | | | Previously, the synthesized AST contained an rvalue DeclRefExpr for 'self'. Now, it has an lvalue DeclRefExpr wrapped in an lvalue-to-rvalue ImplicitCastExpr, which is what's generated when an ivar access is written in the source. No (intended) functionality change. llvm-svn: 199225
* Update CodeGen to use DLL storage class for dllimport/dllexportNico Rieck2014-01-142-9/+27
| | | | | | | With the old linkage types removed, set the linkage to external for both dllimport and dllexport to reflect what's currently supported. llvm-svn: 199220
* Clarify the LibTooling.rst a bitEli Bendersky2014-01-141-2/+2

* Switch around the order of MSVCCompat and MicrosoftExtAlp Toker2014-01-142-3/+2
| | | | | | | | | | | | Full language modes usually get listed before minor language extensions in LangOpts, so that subsequent sub-modes can predicate on the major modes. This also lends to a cleanup in CompilerInvocation to better indicate to the reader that MSVCCompat is a superset of MicrosoftExt. Cleanup only. llvm-svn: 199210
* Rename language option MicrosoftMode to MSVCCompatAlp Toker2014-01-1420-48/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | There's been long-standing confusion over the role of these two options. This commit makes the necessary changes to differentiate them clearly, following up from r198936. MicrosoftExt (aka. fms-extensions): Enable largely unobjectionable Microsoft language extensions to ease portability. This mode, also supported by gcc, is used for building software like FreeBSD and Linux kernel extensions that share code with Windows drivers. MSVCCompat (aka. -fms-compatibility, formerly MicrosoftMode): Turn on a special mode supporting 'heinous' extensions for drop-in compatibility with the Microsoft Visual C++ product. Standards-compilant C and C++ code isn't guaranteed to work in this mode. Implies MicrosoftExt. Note that full -fms-compatibility mode is currently enabled by default on the Windows target, which may need tuning to serve as a reasonable default. See cfe-commits for the full discourse, thread 'r198497 - Move MS predefined type_info out of InitializePredefinedMacros' No change in behaviour. llvm-svn: 199209

* clang-format: Fix bug introduced in r198871.Daniel Jasper2014-01-143-3/+9
| | | | | | | | | | | | We cannot simply change the start column to accomodate for the @ in an ObjC string literal as that will make clang-format happily violate the column limit. Use a different workaround instead. However, a better long-term solution might be to join the @ and the rest of the literal into a single token. llvm-svn: 199198
* Disable this test for windows buildersDavid Majnemer2014-01-141-0/+2
| | | | | | | This test provides definitions of size_t which are at odds with -fms-compatibility. Disable this test on those builders (for now). llvm-svn: 199196
* Switch to ssize_t from size_t to unbreak windows builders.David Majnemer2014-01-141-3/+3
| | | | | | | Builders that have -fms-compatibility on by default define size_t implicitly. Tests that provide conflicting definitions would cause unintended failures. llvm-svn: 199195
* Sema: Predefine size_t in MSVC Compatibility modeDavid Majnemer2014-01-142-0/+3
| | | | | | | | MSVC defines size_t without any explicit declarations. This change allows us to be compatible with TUs that depend on this declaration appearing from nowhere. llvm-svn: 199190

| | | | | | Instead of mapping them to their semantics as a custom part of the parser, they instead map declaratively through the rest of the attribute system. llvm-svn: 199175
* [ms-abi] Small Change to pack+alignment interaction.Warren Hunt2014-01-142-4/+30
| | | | | | | | | This patch makes a small behavioral change to the interaction between pack and alignment. Specifically it makes __declspec(align()) on a field change that field's alignment without respect to pack but the alignment change to the record alignment as a whole still obeys pack. llvm-svn: 199172
* [ms-abi] Remove duplicated vbptr offset codeReid Kleckner2014-01-141-39/+5
| | | | | | | | | Record layout will tell us the offset of a shared vbptr inside a non-virtual base. No functionality change. llvm-svn: 199171
* Consumed analysis: add two new attributes which fine-tune the behavior ofDeLesley Hutchins2014-01-145-240/+317
| | | | | | | | consumable objects. These are useful for implementing error codes that must be checked. Patch also includes some significant refactoring, which was necesary to implement the new behavior. llvm-svn: 199169
* [ms-abi] Report VBPtrOffset correctlyWarren Hunt2014-01-144-11/+10
| | | | | | | | | | Although VBPtrs were being placed correctly by the ms-abi layout engine, their offsets were being improperly reported to the ASTRecordLayout builder due to a bug. This patch fixes that and fixes the test cases to use the correct values. y llvm-svn: 199168
* [ms-abi] Always generate complete constructors in the Microsoft C++ ABIReid Kleckner2014-01-133-5/+38
| | | | | | | | Fixes PR18435, where we generated a base ctor instead of a complete ctor, and so failed to construct virtual bases when constructing the complete object. llvm-svn: 199160
* [ms-abi] Reordering __declspec(align) pragma pack handlingWarren Hunt2014-01-132-5/+34
| | | | | | | | This patch moves the check for pragma pack until after the application of __declspec align to before pragma pack. This causes observable changes in the use of tail padding for bases. A test case is included. llvm-svn: 199154
* clang-cl: Ignore /fallback when not actually compiling (PR18456)Hans Wennborg2014-01-132-1/+7

| | | | | | | | | | | | so bump the minimum version in the standalone Clang CMake project as well. As I mentioned on the LLVM commit version of this, if this causes any trouble for folks, just let me know. I'm trying to avoid re-implementing functionality in CMake, but I will if there are problems using the newer versions. llvm-svn: 199152
