* Make FileManager::getFileSystemOptions consistent with ↵Yaron Keren2015-08-261-2/+2
| | | | | | | | | | CompilerInstance::getFileSystemOpts and CompilerInvocation::getFileSystemOpts by renaming it to getFileSystemOpts, marking the const-returning access method const and adding a non-const version, making the function prototypes identical to CompilerInstance::getFileSystemOpts. llvm-svn: 246026
* [OPENMP 4.0] Initial support for array sections.Alexey Bataev2015-08-254-0/+28
| | | | | | | | Adds parsing/sema analysis/serialization/deserialization for array sections in OpenMP constructs (introduced in OpenMP 4.0). Currently it is allowed to use array sections only in OpenMP clauses that accepts list of expressions. Differential Revision: http://reviews.llvm.org/D10732 llvm-svn: 245937

* [modules] Stop updating all identifiers when writing a module. This isRichard Smith2015-08-243-17/+40
| | | | | | | unnecessary in C++ modules (where we don't need the identifiers for their Decls) and expensive. llvm-svn: 245821
* [modules] Further simplification and speedup of redeclaration chain loading.Richard Smith2015-08-225-135/+62
| | | | | | | | Instead of eagerly deserializing a list of DeclIDs when we load a module file and doing a binary search to find the redeclarations of a decl, store a list of redeclarations of each chain before the first declaration and load it directly. llvm-svn: 245789
* [modules] Remove some dead code after r245779.Richard Smith2015-08-222-170/+35

* [modules] Rearrange how redeclaration chains are loaded, to remove a walk overRichard Smith2015-08-224-137/+150
| | | | | | | | | | | | | | | | | | | | | | | | | all modules and reduce the number of declarations we load when loading a redeclaration chain. The new approach is: * when loading the first declaration of an entity within a module file, we first load all declarations of the entity that were imported into that module file, and then load all the other declarations of that entity from that module file and build a suitable decl chain from them * when loading any other declaration of an entity, we first load the first declaration from the same module file As before, we complete redecl chains through name lookup where necessary. To make this work, I also had to change the way that template specializations are stored -- it no longer suffices to track only canonical specializations; we now emit all "first local" declarations when emitting a list of specializations for a template. On one testcase with several thousand imported module files, this reduces the total runtime by 72%. llvm-svn: 245779
* [OPENMP 4.1] Initial support for 'simdlen' clause.Alexey Bataev2015-08-212-0/+13
| | | | | | Add parsing/sema analysis for 'simdlen' clause in simd directives. Also add check that if both 'safelen' and 'simdlen' clauses are specified, the value of 'simdlen' parameter is less than the value of 'safelen' parameter. llvm-svn: 245692
* [modules] When we see a definition of a function for which we already have aRichard Smith2015-08-211-3/+2

* [OPENMP 4.1] Initial support for modifiers in 'linear' clause.Alexey Bataev2015-08-202-0/+4
| | | | | | | | | | | | | | | | | | | | | | OpenMP 4.1 adds 3 optional modifiers to 'linear' clause. Format of 'linear' clause has changed to: ``` linear(linear-list[ : linear-step]) ``` where linear-list is one of the following ``` list modifier(list) ``` where modifier is one of the following: ``` ref (C++) val (C/C++) uval (C++) ``` Patch adds parsing and sema analysis for these modifiers. llvm-svn: 245550

* [OPENMP 4.1] Allow variables with reference types in private clauses.Alexey Bataev2015-08-182-0/+7
| | | | | | OpenMP 4.1 allows to use variables with reference types in all private clauses (private, firstprivate, lastprivate, linear etc.). Patch allows to use such variables and fixes codegen for linear variables with reference types. llvm-svn: 245268

* [OPENMP] Fix for http://llvm.org/PR24371: Assert failure compiling blender 2.75.Alexey Bataev2015-08-142-0/+7
| | | | | | | blender uses statements expression in condition of the loop under control of the '#pragma omp parallel for'. This condition is used several times in different expressions required for codegen of the loop directive. If there are some variables defined in statement expression, it fires an assert during codegen because of redefinition of the same variables. We have to rebuild several expression to be sure that all variables are unique. llvm-svn: 245041

This allows a smaller set of files to be sent to a remote build worker when building with explicit modules (for instance, module map files need not be sent along with the corresponding precompiled modules). This doesn't actually make the embedded files visible to header search, so it's not useful as a packaging format for public header files. llvm-svn: 245028

* [modules] Change the way we deal with .d output for explicitly-specified moduleRichard Smith2015-08-131-10/+15
| | | | | | | | | | | | | files: include the .pcm file itself in the .d output, rather than including its own input files. Other forms of module file continue to be transparent for .d output. Arguably, the input files for the .pcm file are still inputs to the compilation, but that's unnecessary for make-like build systems (where the mtime of the .pcm file is sufficient) and harmful for smarter build systems that know about module files and want to track only the local dependencies. llvm-svn: 244923

This exposed a couple of bugs: * the odr violation check didn't deal properly with mergeable declarations if the declaration retained by name lookup wasn't in the canonical definition of the class * the (broken) RewriteDecl mechanism would emit two name lookup tables for the same DeclContext into the same module file (one as part of the rewritten declaration and one as a visible update for the old declaration) These are both fixed too. llvm-svn: 244192

| | | | | | | | | | | | | | | | In llvm commit r243581, a reverse range adapter was added which allows us to change code such as for (auto I = Fields.rbegin(), E = Fields.rend(); I != E; ++I) { in to for (const FieldDecl *I : llvm::reverse(Fields)) This commit changes a few of the places in clang which are eligible to use this new adapter. llvm-svn: 243663
* [OPENMP 4.1] Initial support for extended 'ordered' clause.Alexey Bataev2015-07-302-2/+8
| | | | | | | | OpenMP 4.1 introduces optional argument '(n)' for 'ordered' clause, where 'n' is a number of loops that immediately follow the directive. 'n' must be constant positive integer expressions and it must be less or equal than the number of the loops in the resulting loop nest. Patch adds parsing and semantic analysis for this optional argument. llvm-svn: 243635

Previously we failed to merge sometimes it because it's not visible to name lookup. (In passing, remove redundant __va_list_tag typedefs that we were creating for some ABIs. These didn't affect the mangling or representation of the type.) * For Decls derived from Redeclarable that are not in fact redeclarable (implicit params, function params, ObjC type parameters), remove them from the list of expected redeclarable decls. llvm-svn: 243259
