2008-11-17Eliminate all of the placeholder identifiers used for constructors,Douglas Gregor
destructors, and conversion functions. The placeholders were used to work around the fact that the parser and some of Sema really wanted declarators to have simple identifiers; now, the code that deals with declarators will use DeclarationNames. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59469 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-17Introduction the DeclarationName class, as a single, general method ofDouglas Gregor
representing the names of declarations in the C family of languages. DeclarationName is used in NamedDecl to store the name of the declaration (naturally), and ObjCMethodDecl is now a NamedDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59441 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-16Fix PR3077: tokens that come from macro expansions whose macro wasChris Lattner
defined in a system header should be treated as system header tokens even if they are instantiated in a different place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59418 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-14Add a new expression node, CXXOperatorCallExpr, which expresses aDouglas Gregor
function call created in response to the use of operator syntax that resolves to an overloaded operator in C++, e.g., "str1 + str2" that resolves to std::operator+(str1, str2)". We now build a CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But only for binary operators, where we actually implement overloading) I decided *not* to refactor the current CallExpr to make it abstract (with FunctionCallExpr and CXXOperatorCallExpr as derived classes). Doing so would allow us to make CXXOperatorCallExpr a little bit smaller, at the cost of making the argument and callee accessors virtual. We won't know if this is going to be a win until we can parse lots of C++ code to determine how much memory we'll save by making this change vs. the performance penalty due to the extra virtual calls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59306 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-12Don't build identifiers for C++ constructors, destructors, orDouglas Gregor
conversion functions. Instead, we just use a placeholder identifier for these (e.g., "<constructor>") and override NamedDecl::getName() to provide a human-readable name. This is one potential solution to the problem; another solution would be to replace the use of IdentifierInfo* in NamedDecl with a different class that deals with identifiers better. I'm also prototyping that to see how it compares, but this commit is better than what we had previously. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59193 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-06Parsing, ASTs, and semantic analysis for the declaration of overloadedDouglas Gregor
operators in C++. Overloaded operators can be called directly via their operator-function-ids, e.g., "operator+(foo, bar)", but we don't yet implement the semantics of operator overloading to handle, e.g., "foo + bar". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58817 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-02More fallout from r58501: primary fix is some more corrections to make Eli Friedman
the types for size_t and ptrdiff_t more accurate. I think all of these are correct, but please compare the defines for __PTRDIFF_TYPE__ and __SIZE_TYPE__ to gcc to double-check; this particularly applies to those on BSD variants, since I'm not sure what they do here; I assume here that they're the same as on Linux. Fixes wchar_t to be "int", not "unsigned int" (which I think is correct on everything but Windows). Fixes ptrdiff_t to be "int" rather than "short" on PIC16; "short" is an somewhat strange choice because it normally gets promoted, and it's not consistent with the choice for size_t. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58556 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-31Fix a bug that was introduced in 58501. Ideally I think we should force all ↵Anders Carlsson

2008-10-31Made the mechanism of defining preprocessor defs for maxint, ptrdiff_t, wcharSanjiv Gupta
etc more generic. For some targets, long may not be equal to pointer size. For example: PIC16 has int as i16, ptr as i16 but long as i32. Also fixed a few build warnings in assert() functions in CFRefCount.cpp, CGDecl.cpp, SemaDeclCXX.cpp and ParseDeclCXX.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58501 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-26Fix the rest of rdar://6243860 hopefully. This requires changing FileIDInfoChris Lattner
to whether the fileid is a 'extern c system header' in addition to whether it is a system header, most of this is spreading plumbing around. Once we have that, PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to base the system header state on FileIDInfo instead of HeaderSearch. Finally, in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness of a file being entered can be set due to the #includer or the #includee. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56688 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-21Initial implementation of Windows x86 target; at the moment, the only Eli Friedman
difference from generic x86 is the defines. The rest is non-trivial to implement. I'm not planning on adding any more targets myself; if there are any targets anyone is currently using that are missing, feel free to add them, or ask me to add them. This concludes the work I'm planning for the TargetInfo implementations at the moment; all the other issues with TargetInfo require some API changes, and I haven't really thought it through. Some of the remaining issues: allowing targets to define size_t and wchar_t properly, adding some sort of __builtin_type_info intrinsic so we can finish clang's limits.h and float.h and get rid of a massive number of macro definitions, allowing target-specific command-line options, allowing target-specific defaults for certain command-line options like -fms-extensions, exposing vector alignment outside of the description string, exposing endianness outside of the description string, allowing targets to expose special bit-field layout requirements, exposing some sort of custom hook for call generation in CodeGen, and adding CPU selection to control defines like __SSE__. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55098 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-21First cut at OS detection, taking advantage of the new generic targets. Eli Friedman
This approach allows adding OS-specific targets/defines/etc. without completely breaking unknown subtargets. No new subtargets yet, although I plan to add x86-Linux soon. Others can add targets that they use as needed; adding a new subtarget takes very little code. Also does some fixups for description strings; a lot of them were unspecified. I think all the ones I added are correct, but they're unverified; corrections are welcome. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55091 91177308-0d34-0410-b5e6-96231b3b80d8
