* [OPENMP] Fix PR38903: Crash on instantiation of the non-dependentAlexey Bataev2018-09-131-0/+10
| | | | | | | | | | | declare reduction. If the declare reduction construct with the non-dependent type is defined in the template construct, the compiler might crash on the template instantition. Reworked the whole instantiation scheme for the declare reduction constructs to fix this problem correctly. llvm-svn: 342151
* [OPENMP] Fix PR38902: support ADL for declare reduction constructs.Alexey Bataev2018-09-121-1/+106
| | | | | | | Added support for argument-dependent lookup when trying to find the required declare reduction decl. llvm-svn: 342062
* [OPENMP] Simplified checks for declarations in declare target regions.Alexey Bataev2018-09-111-106/+36
| | | | | | | | Sema analysis should not mark functions as an implicit declare target, it may break codegen. Simplified semantic analysis and removed extra code for implicit declare target functions. llvm-svn: 341939
* [OpenMP] Add support for nested 'declare target' directivesKelvin Li2018-09-101-8/+3
| | | | | | | | | | | Add the capability to nest multiple declare target directives - including header files within a declare target region. Differential Revision: https://reviews.llvm.org/D51378 Patch by Patrick Lyster llvm-svn: 341766
* [OPENMP] Fix processing of declare target construct.Alexey Bataev2018-08-141-24/+5
| | | | | | | The attribute marked as inheritable since OpenMP 5.0 supports it + additional fixes to support new functionality. llvm-svn: 339704

* [OPENMP] Mark variables captured in declare target region as implicitlyAlexey Bataev2018-08-071-7/+16

* [OPENMP] Fix PR38256: Fix locations of the artificial conditional op.Alexey Bataev2018-07-251-1/+2
| | | | | | | Fixed the source locations of the conditional op so that they don'r crash coverage pass. llvm-svn: 337928
* [OPENMP] Do not mark local variables as declare target.Alexey Bataev2018-07-091-1/+5
| | | | | | | | | When the parsing of the functions happens inside of the declare target region, we may erroneously mark local variables as declare target thought they are not. This attribute can be applied only to global variables. llvm-svn: 336592

* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-091-124/+124
| | | | | | | | | | | | | | | | | | | This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

* [OPENMP] Analyze the type of the mapped entity instead of its base.Alexey Bataev2018-05-021-1/+8
| | | | | | | If the mapped entity is a data member, we erroneously checked the type of its base rather than the type of the mapped entity itself. llvm-svn: 331385
* [OPENMP] Do not emit warning for implicitly declared target functions.Alexey Bataev2018-05-021-14/+16
| | | | | | | Since upcoming OpenMP 5.0 functions can be mapped implicitly as declare target and we should not emit warnings for such functions. llvm-svn: 331377
* [OPENMP] Do not emit warning about non-declared target function params.Alexey Bataev2018-04-301-1/+1
| | | | | | | | We should not emit warning that the parameters are not marked as declare target, these declaration are local and cannot be marked as declare target. llvm-svn: 331211

* [OPENMP] Codegen for declare target with link clause.Alexey Bataev2018-03-261-6/+18
| | | | | | | | If the link clause is used on the declare target directive, the object should be linked on target or target data directives, not during the codegen. Patch adds support for this clause. llvm-svn: 328544
* [OPENMP, NVPTX] Globalization of the private redeclarations.Alexey Bataev2018-03-201-16/+38
| | | | | | | | If the generic codegen is enabled and private copy of the original variable escapes the declaration context, this private copy should be globalized just like it was the original variable. llvm-svn: 327985

* Re-land "[Sema] Make getCurFunction() return null outside function parsing"Reid Kleckner2018-03-121-40/+40
| | | | | | | | | | | | | | This relands r326965. There was a null dereference in typo correction that was triggered in Sema/diagnose_if.c. We are not always in a function scope when doing typo correction. The fix is to add a null check. LLVM's optimizer made it hard to find this bug. I wrote it up in a not-very-well-editted blog post here: http://qinsb.blogspot.com/2018/03/ub-will-delete-your-null-checks.html llvm-svn: 327334
* Revert "[Sema] Make getCurFunction() return null outside function parsing"Reid Kleckner2018-03-081-40/+40
| | | | | | | | | | This reverts r326965. It seems to have caused repeating test failures in clang/test/Sema/diagnose_if.c on some buildbots. I cannot reproduce the problem, and it's not immediately obvious what the problem is, so let's revert to green. llvm-svn: 326974
* [Sema] Make getCurFunction() return null outside function parsingReid Kleckner2018-03-081-40/+40
| | | | | | | | | | | | | | | | | | | | | | | | Summary: Before this patch, Sema pre-allocated a FunctionScopeInfo and kept it in the first, always present element of the FunctionScopes stack. This meant that Sema::getCurFunction would return a pointer to this pre-allocated object when parsing code outside a function body. This is pretty much always a bug, so this patch moves the pre-allocated object into a separate unique_ptr. This should make bugs like PR36536 a lot more obvious. As you can see from this patch, there were a number of places that unconditionally assumed they were always called inside a function. However, there are also many places that null checked the result of getCurFunction(), so I think this is a reasonable direction.

* [OPENMP] Treat local variables in CUDA mode as thread local.Alexey Bataev2018-03-021-15/+59
| | | | | | | | In CUDA mode all local variables are actually thread local|threadprivate, not private, and, thus, they cannot be shared between threads|lanes. llvm-svn: 326590
* Remove redundant casts. NFCGeorge Burgess IV2018-03-011-1/+1
| | | | | | | | | | | | | | | | | | | So I wrote a clang-tidy check to lint out redundant `isa`, `cast`, and `dyn_cast`s for fun. This is a portion of what it found for clang; I plan to do similar cleanups in LLVM and other subprojects when I find time. Because of the volume of changes, I explicitly avoided making any change that wasn't highly local and obviously correct to me (e.g. we still have a number of foo(cast<Bar>(baz)) that I didn't touch, since overloading is a thing and the cast<Bar> did actually change the type -- just up the class hierarchy). I also tried to leave the types we were cast<>ing to somewhere nearby, in cases where it wasn't locally obvious what we were dealing with before. llvm-svn: 326416
