* [Frontend] Correctly handle instantiating ctors with skipped bodiesIlya Biryukov2017-12-281-13/+13
| | | | | | | | | | | | | | | | Summary: Previsouly clang tried instantiating member initializers even if ctor body was skipped, this caused spurious errors (see the test).

* [Index] Reduce size of SymbolInfo struct.Sam McCall2017-12-231-30/+35
| | | | | | | | | | | | | | | | | | | | | Summary: This is currently 16 bytes, the patch reduces it to 4. (Building with clang on linux x84, I guess others are similar) The only subfield that might need a bigger type is SymbolPropertySet, I've moved it to the end of the struct so if it grows, SymbolInfo will only be 8 bytes. With a full index of namespace-scope symbols from the LLVM project (200k) loaded into clangd, this saves ~2MB of RAM.

* Diagnose the various invalid decl-specifiers on nontype template parameters.Faisal Vali2017-12-221-0/+54
| | | | | | | | | | | | | The standard correctly forbids various decl-specifiers that dont make sense on non-type template parameters - such as the extern in: template<extern int> struct X; This patch implements those restrictions (in a fashion similar to the corresponding checks on function parameters within ActOnParamDeclarator). Credit goes to miyuki (Mikhail Maltsev) for drawing attention to this issue, authoring the initial versions of this patch, and supporting the effort to re-engineer it slightly. Thank you!

* [Modules] Change private modules rules and warningsBruno Cardoso Lopes2017-12-222-40/+71
| | | | | | | | | | | | | | | | We used to advertise private modules to be declared as submodules (Foo.Private). This has proven to not scale well since private headers might carry several dependencies, introducing unwanted content into the main module and often causing dep cycles. Change the canonical way to name it to Foo_Private, forcing private modules as top level ones, and provide warnings under -Wprivate-module to suggest fixes for other private naming. Update documentation to reflect that. rdar://problem/31173501 llvm-svn: 321337

* [CodeGen] Fix crash when a function taking transparent union is redeclared.Volodymyr Sapsai2017-12-211-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a function taking transparent union is declared as taking one of union members earlier in the translation unit, clang would hit an "Invalid cast" assertion during EmitFunctionProlog. This case corresponds to function f1 in test/CodeGen/transparent-union-redecl.c. We decided to cast i32 to union because after merging function declarations function parameter type becomes int, CGFunctionInfo::ArgInfo type matches with ABIArgInfo type, so we decide it is a trivial case. But these types should also be castable to parameter declaration type which is not the case here. The fix is in checking for the trivial case if ABIArgInfo type matches with parameter declaration type. It exposed inconsistency that we check hasScalarEvaluationKind for different types in EmitParmDecl and EmitFunctionProlog, and comment says they should match. Additional tests in Sema/transparent-union.c capture current behavior and make sure there are no regressions. rdar://problem/34949329 Reviewers: rjmccall, rafael Reviewed By: rjmccall Subscribers: aemerson, cfe-commits, kristof.beyls Differential Revision: https://reviews.llvm.org/D41311 llvm-svn: 321296
