2011-09-24Treat list-initialization of scalars as a first-class citizen in C++11.Sebastian Redl
Allow empty initializer lists for scalars, which mean value-initialization. Constant evaluation for single-element and empty initializer lists for scalars. Codegen for empty initializer lists for scalars. Test case comes in next commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140459 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-22Don't remove filters.Bill Wendling
It's not valid to remove filters from landingpad instructions, even if we catch the type. The metadata won't be set up correctly. Testcase is projects/llvm-test/SingleSource/UnitTests/EH/filter-2.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140335 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-22Only trigger the initialize-an-array-via-elementwise-copy/move codeDouglas Gregor
generation when we're dealing with an implicitly-defined copy or move constructor. And, actually set the implicitly-defined bit for implicitly-defined constructors and destructors. Should fix self-host. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140334 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-22Explicitly-defaulted copy/move constructors are not "implicit", butDouglas Gregor
they still need the logic to cope with array member initialization. Fixes PR10720. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140302 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-21ANSI C requires that a call to an unprototyped function type succeedJohn McCall
if the definition has a non-variadic prototype with compatible parameters. Therefore, the default rule for such calls must be to use a non-variadic convention. Achieve this by casting the callee to the function type with which it is required to be compatible, unless the target specifically opts out and insists that unprototyped calls should use the variadic rules. The only case of that I'm aware of is the x86-64 convention, which passes arguments the same way in both cases but also sets a small amount of extra information; here we seek to maintain compatibility with GCC, which does set this when calling an unprototyped function. Addresses PR10810 and PR10713. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140241 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-21Change "ivar" to true for a boolean function argument. Since string ↵Richard Trieu
literals are cast to true, this should no effect on behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140231 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20Create a MipsTargetCodeGenInfo object for mips64/mips64el. The size of theAkira Hatanaka
UnwindException structure is 32 for mips64. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140165 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20Add a parameter to MipsTargetCodeGenInfo's constructor.Akira Hatanaka
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140161 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20Don't assume that the clause is a GlobalVariable. It could be a constant.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140123 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19Add list initialization for complex numbers in C. Essentially, this allows ↵Eli Friedman
"_Complex float x = {1.0f, 2.0f};". See changes to docs/LanguageExtensions.html for a longer description. <rdar://problem/9397672>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140090 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19The eh.selector intrinsic isn't used anymore. Replace the check here with aBill Wendling
check for the landingpad instruction instead. This check looks at each of the clauses in the landingpad instruction. If it's a catch clause, it compares the name directly with the global. If it's a filter clause, it has to look through each value in the filer to see if any have the prefix. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140075 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19OpenCL: introduce support for function scope __local variablesPeter Collingbourne
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140068 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19In CodeGenAction::ExecuteAction() use SourceManager::translateFileLineCol()Argyrios Kyrtzidis
instead of getLocation() since we don't care about expanded macro arguments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140061 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19Rename SourceLocation::getFileLocWithOffset -> getLocWithOffset.Argyrios Kyrtzidis
It already works (and is useful with) macro locs as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140057 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19Throw the switch to convert clang to the new exception handling model!Bill Wendling
This model uses the 'landingpad' instruction, which is pinned to the top of the landing pad. (A landing pad is defined as the destination of the unwind branch of an invoke instruction.) All of the information needed to generate the correct exception handling metadata during code generation is encoded into the landingpad instruction. The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic call. It's lowered in much the same way as the intrinsic is. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140049 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-19In apple-kext mode, use external linkage for explicit template instantiationsJohn McCall
instead of internal linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140030 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-18PR10304: Do not call destructors for data members from union destructors. ↵Richard Smith
Prior to C++11, this has no effect since any such destructors must be trivial, and in C++11 such destructors must not be called. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139997 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-15Refactor the load of the exception pointer and the exception selector from theirBill Wendling
storage slot into helper functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139826 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-15Rewrite this loop to use partial destruction; I'm not sure it'sJohn McCall
possible for that to matter right now, but eventually I think we'll need to unify this better, and then it might. Also, use a more efficient looping structure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139788 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-15We don't generate null initializer expressions anymore, andJohn McCall
we don't need to. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139769 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-13Correctly generate IR for casted "builtin" functions, whereJohn McCall
the builtin is really just a predefined declaration. These are totally valid to cast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139657 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Re-commit r139643.Eli Friedman
Make clang use Acquire loads and Release stores where necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139650 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-13Turn off the generation of unaligned atomic load/store; I'm going to ↵Eli Friedman
explicitly error out on such cases in the backend, at least for the moment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139640 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Refactoring, mostly to give ObjCPropertyDecls stronger invariants forJohn McCall
their semantic attributes and then to take advantage of that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139615 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Switch LangOptions over to a .def file that describes header of theDouglas Gregor
language options. Use that .def file to declare the LangOptions class and initialize all of its members, eliminating a source of annoying initialization bugs. AST serialization changes are next up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139605 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Don't use native atomics on ivars whose size is not a power of two,John McCall
even on architectures that support unaligned access (which is the only way this is otherwise legal, given that ivars apparently do not honor alignment attributes). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139590 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-13Always emit bitfield properties using expression behavior, even if they'reJohn McCall
atomic. This is probably something we should warn about. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139584 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Unify the decision of how to emit property getters and setters into aJohn McCall
single code path. Use atomic loads and stores where necessary. Load and store anything of the appropriate size and alignment with primitive operations instead of going through the call. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139580 91177308-0d34-0410-b5e6-96231b3b80d8
