* Keep the IfStmt node even if the condition is invalidOlivier Goffart2015-10-112-17/+34
| | | | | | | This is important to keep the information in IDE or other tools even if the code contains a few errors llvm-svn: 249982
* [CMake] Always generate and install cmake config files on CMake>=3.0.NAKAMURA Takumi2015-10-101-1/+2
| | | | | | | | | | Currently, cmake config files are only generated and installed when CLANG_BUILD_STANDALONE set, which means config file will not be generated or installed when clang is built with llvm. This change removes that restriction. Thanks to Don Hinton <hintonda@gmail.com> http://reviews.llvm.org/D13453 llvm-svn: 249935

* Fix inference of _Nullable for weak Objective-C properties.Douglas Gregor2015-10-096-15/+36
| | | | | | | | | | | | | | | | | | | | The inference of _Nullable for weak Objective-C properties was broken in several ways: * It was back-patching the type information very late in the process of checking the attributes for an Objective-C property, which is just wrong. * It was using ad hoc checks to try to suppress the warning about missing nullability specifiers (-Wnullability-completeness), which didn't actual work in all cases (rdar://problem/22985457) * It was inferring _Nullable even outside of assumes-nonnull regions, which is wrong. Putting the inference of _Nullable for weak Objective-C properties in the same place as all of the other inference logic fixes all of these ills. llvm-svn: 249896
* Add a fixme to handleTargetFeatures.Eric Christopher2015-10-091-0/+2
| | | | | | | | | The goal of wanting this to avoid munging the feature list is so that it can be used for various targets as a way of both adding and verifying the features that are going to be output into the IR. llvm-svn: 249894

* [CMake] Fixing LTO library path passed into bootstrap builds.Chris Bieneman2015-10-091-1/+1

* Analysis: Make CFG::graph_iterator dereference to non-constDuncan P. N. Exon Smith2015-10-091-1/+1
| | | | | | | | | | | | | | | Since the original commit in r145858, we've had `CFG::graph_iterator` and `CFG::const_graph_iterator`, and both have derefenced to a `const`-ified `value_type`. The former has an implicit conversion to non-`const`, which is how this worked at all until r249782 started using the dereference operator (partially reverted in r249783). This fixes the non-const iterator to be non-const (sometimes const-iterators are intentional, but with a separate const-ified class (and a non-const implicit conversion leak) that's not likely to be the case here). llvm-svn: 249849

* [VFS] Wire up driver VFS through tooling.Benjamin Kramer2015-10-091-4/+5
| | | | | | | | Sadly I don't currently have a way to tests this as the driver is always initialized with the default triple and finding system headers is system specific. llvm-svn: 249831

* [VFS] Port tooling to use the in-memory file system.Benjamin Kramer2015-10-093-29/+80

* Skip NonNull sema checks in unevaluated contexts.Eric Fiselier2015-10-092-1/+5
| | | | | | | | | | | | | | Summary: Currently when a function annotated with __attribute__((nonnull)) is called in an unevaluated context with a null argument a -Wnonnull warning is emitted. This warning seems like a false positive unless the call expression is potentially evaluated. Change this behavior so that the non-null warnings use DiagRuntimeBehavior so they wont emit when they won't be evaluated.

* Expose -f[no]ms-{compatibility,extensions} in clang-cl (PR25114)Hans Wennborg2015-10-082-4/+10
| | | | | | | | These are enabled by default in clang-cl, because the whole idea is that it should work like cl.exe, but I suppose it can make sense to disable them if someone wants to compile code in a more strict mode. llvm-svn: 249775

* Handle sse turning on mmx, but no -mmx not turning off SSE.Eric Christopher2015-10-083-16/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rationale : // sse3 __m128d test_mm_addsub_pd(__m128d A, __m128d B) { return _mm_addsub_pd(A, B); } // mmx void shift(__m64 a, __m64 b, int c) { _mm_slli_pi16(a, c); _mm_slli_pi32(a, c); _mm_slli_si64(a, c); _mm_srli_pi16(a, c); _mm_srli_pi32(a, c); _mm_srli_si64(a, c); _mm_srai_pi16(a, c); _mm_srai_pi32(a, c); } clang -msse3 -mno-mmx file.c -c For this code we should be able to explicitly turn off MMX without affecting the compilation of the SSE3 function and then diagnose and error on compiling the MMX function. This is a preparatory patch to the actual diagnosis code which is coming in a future patch. This sets us up to have the correct information where we need it and verifies that it's being emitted for the backend to handle. llvm-svn: 249733

* [clang-cl] Make /EHs turn on C++ EH once againReid Kleckner2015-10-082-12/+6
| | | | | | | | | | | C++ exceptions are still off by default, which is similar to how C++ cleanups are off by default in MSVC. If you use clang instead of clang-cl, exceptions are also still off by default. In the future, when C++ EH is proven to be stable, we may flip the default for that driver to be consistent with other platforms. llvm-svn: 249704
* Simplify DefaultCPU in ARMTargetInfoRenato Golin2015-10-082-31/+18
| | | | | | | | | | | | | | | | | | Simplifying the convoluted CPU handling in ARMTargetInfo. The default base CPU on ARM is ARM7TDMI, arch ARMv4T, and ARMTargetInfo had a different one. This wasn't visible from Clang because the driver selects the defaults and sets the Arch/CPU features directly, but the constructor depended on the CPU, which was never used. This patch corrects the mistake and greatly simplifies how CPU is dealt with (essentially by removing the duplicated DefaultCPU field). Tests updated. llvm-svn: 249699

* [MSVC Compat] Try to treat an implicit, fixed enum as an unfixed enumDavid Majnemer2015-10-087-11/+21
| | | | | | | | | | | | | | | | | | consider the following: enum E *p; enum E { e }; The above snippet is not ANSI C because 'enum E' has not bee defined when we are processing the declaration of 'p'; however, it is a popular extension to make the above work. This would fail using the Microsoft enum semantics because the definition of 'E' would implicitly have a fixed underlying type of 'int' which would trigger diagnostic messages about a mismatch between the declaration and the definition. Instead, treat fixed underlying types as not fixed for the purposes of the diagnostic. llvm-svn: 249674
* [OPENMP 4.1] Codegen for array sections/subscripts in 'reduction' clause.Alexey Bataev2015-10-0816-190/+870

* Update a few more tests in response to the MS ABI enum semanticsDavid Majnemer2015-10-0813-15/+15
| | | | | | | Our self hosting buildbots found a few more tests which weren't updated to reflect that the enum semantics are part of the Microsoft ABI. llvm-svn: 249670
* [Sema] Tweak incomplete enum types on MSVC ABI targetsDavid Majnemer2015-10-085-6/+8
| | | | | | | | | Enums without an explicit, fixed, underlying type are implicitly given a fixed 'int' type for ABI compatibility with MSVC. However, we can enforce the standard-mandated rules on these types as-if we didn't know this fact if the tag is not part of a definition. llvm-svn: 249667
* Update tests touched by r249656David Majnemer2015-10-0820-32/+33
| | | | | | | | | These test updates almost exclusively around the change in behavior around enum: enums without a definition are considered incomplete except when targeting MSVC ABIs. Since these tests are interested in the 'incomplete-enum' behavior, restrict them to %itanium_abi_triple. llvm-svn: 249660

| | | | | | | | | | -fms-compatibility No ABI for C++ currently makes it possible to implement the standard 100% perfectly. We wrongly hid some of our compatible behavior behind -fms-compatibility instead of tying it to the compiler ABI. llvm-svn: 249656
* Stop messing with the 'g' group of options in CompilerInvocation.Douglas Katzman2015-10-08227-392/+480
| | | | | | | | | | | | | | | | With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation. Also fix a bug in the Windows compatibility argument parsing in which the "rightmost argument wins" principle failed. Differential Revision: http://reviews.llvm.org/D13221 llvm-svn: 249655

* Don't emit exceptional stackrestore cleanups around inalloca functionsReid Kleckner2015-10-084-34/+16
| | | | | | | | The backend restores the stack pointer after recovering from an exception. This is similar to r245879, but it doesn't try to use the normal cleanup mechanism, so hopefully it won't cause the same breakage. llvm-svn: 249640
* Make clang_Cursor_getMangling not mangle if the declaration isn't mangledEhsan Akhgari2015-10-083-1/+12
| | | | | | | | | | | | Right now clang_Cursor_getMangling will attempt to mangle any declaration, even if the declaration isn't mangled (extern C). This results in a partially mangled name which isn't useful for much. This patch makes clang_Cursor_getMangling return an empty string if the declaration isn't mangled. Patch by Michael Wu <mwu@mozilla.com>. llvm-svn: 249639
* [WinEH] Don't use lifetime markers for MS catch parametersReid Kleckner2015-10-072-2/+18
| | | | | | | | | We don't have a good place to put them. Our previous spot was causing us to optimize loads from the exception object to undef, because it was after the catchpad instruction that models the write to the catch object. llvm-svn: 249616
