2010-05-25Improve name mangling for blocks and support mangling of static localDouglas Gregor
variables within blocks. We loosely follow GCC's mangling, but since these are always internal symbols the names don't really matter. I intend to revisit block mangling later, because GCC's mangling is rather verbose. <rdar://problem/8015719>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104610 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-01Complete reimplementation of the synthesis for implicitly-defined copyDouglas Gregor
assignment operators. Previously, Sema provided type-checking and template instantiation for copy assignment operators, then CodeGen would synthesize the actual body of the copy constructor. Unfortunately, the two were not in sync, and CodeGen might pick a copy-assignment operator that is different from what Sema chose, leading to strange failures, e.g., link-time failures when CodeGen called a copy-assignment operator that was not instantiation, run-time failures when copy-assignment operators were overloaded for const/non-const references and the wrong one was picked, and run-time failures when by-value copy-assignment operators did not have their arguments properly copy-initialized. This implementation synthesizes the implicitly-defined copy assignment operator bodies in Sema, so that the resulting ASTs encode exactly what CodeGen needs to do; there is no longer any special code in CodeGen to synthesize copy-assignment operators. The synthesis of the body is relatively simple, and we generate one of three different kinds of copy statements for each base or member: - For a class subobject, call the appropriate copy-assignment operator, after overload resolution has determined what that is. - For an array of scalar types or an array of class types that have trivial copy assignment operators, construct a call to __builtin_memcpy. - For an array of class types with non-trivial copy assignment operators, synthesize a (possibly nested!) for loop whose inner statement calls the copy constructor. - For a scalar type, use built-in assignment. This patch fixes at least a few tests cases in Boost.Spirit that were failing because CodeGen picked the wrong copy-assignment operator (leading to link-time failures), and I suspect a number of undiagnosed problems will also go away with this change. Some of the diagnostics we had previously have gotten worse with this change, since we're going through generic code for our type-checking. I will improve this in a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102853 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-19More refactoring around constructor/destructor code generation.John McCall
Fix some bugs with function-try-blocks and simplify normal try-block code generation. This implementation excludes a deleting destructor's call to operator delete() from the function-try-block, which I believe is correct but which I can't find straightforward support for at a moment's glance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96670 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-18Make deleting and complete dtor variants defer to other dtor variants byJohn McCall
calling them as subroutines. This triggers whenever the alias optimization doesn't, i.e. when the dtor has linkonce linkage or there are virtual bases or it's the deleting dtor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96605 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-16IRgen optimization: cache the value of 'this' and 'vtt' instead ofJohn McCall
repeatedly reloading from an alloca. We still need to create the alloca for debug info purposes (although we currently create it in all cases because of some abstraction boundaries that're hard to break down). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@96403 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-09Pass inline keyword to optimizer as the new InlineHint function attribute.Jakob Stoklund Olesen
At the moment the inlinehint attribute is ignored by the Inliner unless you pass a -respect-inlinehint option. This will soon be the default. The inlinehint attribute is set if the inline keyword is explicitly specified on any declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95623 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-05Standardize the parsing of function type attributes in a way thatJohn McCall
follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95436 91177308-0d34-0410-b5e6-96231b3b80d8
