* Support __builtin_ms_va_list.Charles Davis2015-09-174-0/+7
| | | | | | | | | | | | | | | | | | Summary: This change adds support for `__builtin_ms_va_list`, a GCC extension for variadic `ms_abi` functions. The existing `__builtin_va_list` support is inadequate for this because `va_list` is defined differently in the Win64 ABI vs. the System V/AMD64 ABI. Depends on D1622.

* [OPENMP] Emit __kmpc_cancel_barrier() and code for 'cancellation point' only ↵Alexey Bataev2015-09-152-0/+14
| | | | | | | | | | | | | | if 'cancel' is found. Patch improves codegen for OpenMP constructs. If the OpenMP region does not have internal 'cancel' construct, a call to 'void __kmpc_barrier()' runtime function is generated for all implicit/explicit barriers. If the region has inner 'cancel' directive, then ``` if (__kmpc_cancel_barrier()) exit from outer construct; ``` code is generated. Also, the code for 'canellation point' directive is not generated if parent directive does not have 'cancel' directive. llvm-svn: 247681

* EmitRecord* API change: accepts ArrayRef instead of a SmallVector (NFC)Mehdi Amini2015-09-102-183/+126
| | | | | | | | | | | | | | | This reapply a variant commit r247179 after post-commit review from D.Blaikie. Hopefully I got it right this time: lifetime of initializer list ends as with any expression, which make invalid the pattern: ArrayRef<int> Arr = { 1, 2, 3, 4}; Just like StringRef, ArrayRef shouldn't be used to initialize local variable but only as function argument.

* [OPENMP 4.1] Parsing/sema analysis for extended format of 'if' clause.Alexey Bataev2015-09-032-0/+6
| | | | | | | | | | | | | | | | | OpenMP 4.1 added special 'directive-name-modifier' to the 'if' clause. Format of 'if' clause is as follows: ``` if([ directive-name-modifier :] scalar-logical-expression) ``` The restriction rules are also changed. 1. If any 'if' clause on the directive includes a 'directive-name-modifier' then all 'if' clauses on the directive must include a 'directive-name-modifier'. 2. At most one 'if' clause without a 'directive-name-modifier' can appear on the directive. 3. At most one 'if' clause with some particular 'directive-name-modifier' can appear on the directive. 'directive-name-modifier' is important for combined directives and allows to separate conditions in 'if' clause for simple sub-directives in combined directive. This 'directive-name-modifier' identifies the sub-directive to which this 'if' clause must be applied. llvm-svn: 246747

Original commit message: [modules] Rework serialized DeclContext lookup table management. Instead of walking the loaded ModuleFiles looking for lookup tables for the context, store them all in one place, and merge them together if we find we have too many (currently, more than 4). If we do merge, include the merged form in our serialized lookup table, so that downstream readers never need to look at our imports' tables. This gives a huge performance improvement to builds with very large numbers of modules (in some cases, more than a 2x speedup was observed). llvm-svn: 246582

* [MS ABI] Correctly mangle classes without names for linkage purposesDavid Majnemer2015-08-312-11/+3
| | | | | | | | | | | | | | | | A class without a name for linkage purposes gets a name along the lines of <unnamed-type-foo> where foo is either the name of a declarator which defined it (like a variable or field) or a typedef-name (like a typedef or alias-declaration). We handled the declarator case correctly but it would fall down during template instantiation if the declarator didn't share the tag's type. We failed to handle the typedef-name case at all. Instead, keep track of the association between the two and keep it up to date in the face of template instantiation. llvm-svn: 246469

* [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

| | | | | | | | | | | | | | | | | | | | | | | | | 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 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] 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

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
