* Fix buildbots broken by r254508Andy Gibbs2015-12-021-1/+4
| | | | | | | | | | g++ 4.7 does not allow an inline defaulted virtual destructor to be overridden, giving the error "looser throw specifier for ... overridding ~SCEVPredicate() noexcept (true)" (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53613). The work-around given in the bug report above has been utilised here. llvm-svn: 254511

* [AttributeSet] Overload AttributeSet::addAttribute to reduce compileAkira Hatanaka2015-12-024-17/+63
| | | | | | | | | | | | | | | | | | | | time. The new overloaded function is used when an attribute is added to a large number of slots of an AttributeSet (for example, to function parameters). This is much faster than calling AttributeSet::addAttribute once per slot, because AttributeSet::getImpl (which calls FoldingSet::FIndNodeOrInsertPos) is called only once per function instead of once per slot. With this commit, clang compiles a file which used to take over 22 minutes in just 13 seconds. rdar://problem/23581000 Differential Revision: http://reviews.llvm.org/D15085 llvm-svn: 254491

* [llvm-dwp] Emit a rather fictional debug_cu_indexDavid Blaikie2015-12-027-43/+128
| | | | | | | | | | | | | | This is very rudimentary support for debug_cu_index, but it is enough to allow llvm-dwarfdump to find the offsets for contributions and correctly dump debug_info. It will need to actually find the real signature of the unit and build the real hash table with the right number of buckets, as per the DWP specification. It will also need to be expanded to cover the tu_index as well. llvm-svn: 254489

* Added support for -gmodule debugging when debug info is left in the .o files ↵Greg Clayton2015-12-0222-178/+1140
| | | | | | | | | | | | | | | | | | | | on Darwin. This is done by finding the types that are forward declarations that come from a module, and loading that module's debug info in a separate lldb_private::Module, and copying the type over into the current module using a ClangASTImporter object. ClangASTImporter objects are already used to copy types from on clang::ASTContext to another for expressions so the type copying code has been around for a while. A new FindTypes variant was added to SymbolVendor and SymbolFile: size_t SymbolVendor::FindTypes (const std::vector<CompilerContext> &context, bool append, TypeMap& types); size_t SymbolVendor::FindTypes (const std::vector<CompilerContext> &context, bool append, TypeMap& types); The CompilerContext is a way to represent the exact context of a type and pass it through an agnostic API boundary so that we can find that exact context elsewhere in another file. This was required here because we can have a module that has submodules, both of which have a "foo" type. I am not able to add tests for this yet as we currently don't build our C/C++/ObjC binaries with the clang binary that we build. There are some driver issues where it can't find the header files for the C and C++ standard library which makes compiling these tests hard. We can't also guarantee that if we are building with clang that it supporst the exact format of -gmodule debugging that we are trying to test. We have had other versions of clang that had a different implementation of -gmodule debugging that we are no longer supporting, so we can't enable tests if we are building with clang without compiling something and looking at the structure of the DWARF that was generated to ensure that it is the format we can actually use. llvm-svn: 254476
* AArch64: fix 128-bit shiftsTim Northover2015-12-022-70/+97
| | | | | | | | | | | | | | We mustn't introduce a shift of exactly 64-bits for any inputs, since that's an UNDEF value (and worse, it's not what you want with the natural Arch64 implementation). The generated code is pretty horrific, but I couldn't come up with an obviously better alternative (if the amount is constant EXTR could help). Turns out 128-bit shifts are just nasty. rdar://22491037 llvm-svn: 254475

| | | | | | | | | | | | si_int is already defined in sysroot's siginfo.h emutls.c includes pthread.h which includes asm/siginfo.h which in turn includes asm-generic/siginfo.h and that defines si_int. si_int is also defined in builtin's int_types.h and this leads to errors.
