2010-03-30Remember the regparm attribute in FunctionType::ExtInfo.Rafael Espindola
Fixes PR3782. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99940 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30the big refactoring bits of PR3782.Rafael Espindola
This introduces FunctionType::ExtInfo to hold the calling convention and the noreturn attribute. The next patch will extend it to include the regparm attribute and fix the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99920 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-21Keep track of the size/modification time of each file source-locationDouglas Gregor
entry in a precompiled header, so that we can detect modified files even when we miss in the stat cache. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99149 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Remove the capture, serialization, and deserialization of commentDouglas Gregor
ranges as part of the ASTContext. This code is not and was never used, but contributes ~250k to the size of the Cocoa.h precompiled header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99007 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-19Implement serialization and lazy deserialization of the preprocessingDouglas Gregor
record (which includes all macro instantiations and definitions). As with all lay deserialization, this introduces a new external source (here, an external preprocessing record source) that loads all of the preprocessed entities prior to iterating over the entities. The preprocessing record is an optional part of the precompiled header that is disabled by default (enabled with -detailed-preprocessing-record). When the preprocessor given to the PCH writer has a preprocessing record, that record is written into the PCH file. When the PCH reader is given a PCH file that contains a preprocessing record, it will be lazily loaded (which, effectively, implicitly adds -detailed-preprocessing-record). This is the first case where we have sections of the precompiled header that are added/removed based on a compilation flag, which is unfortunate. However, this data consumes ~550k in the PCH file for Cocoa.h (out of ~9.9MB), and there is a non-trivial cost to gathering this detailed preprocessing information, so it's too expensive to turn on by default. In the future, we should investigate a better encoding of this information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99002 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-16Fix header-search problems with precompiled headers, where theDouglas Gregor
presence or absence of header map arguments when using the precompiled header would cause Clang to get confused about which headers had already been included/imported, along with their controlling macros. The fundamental problem is that the serialization of the header search information was relying on the UIDs of FileEntry objects at PCH generation time and PCH load time to be equivalent, which effectively means that we had to probe the same files in the same order. Differing header map arguments caused an extra FileEntry lookup, but it's easy to imagine other minor command-line arguments triggering this problem. Header-search information is now encoded along with the source-location entry for a file, so that we register information about a file's properties as a header at the same time we create the FileEntry for that file. Fixes <rdar://problem/7743243>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98636 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-10Create a new InjectedClassNameType to represent bare-word references to the John McCall
injected class name of a class template or class template partial specialization. This is a non-canonical type; the canonical type is still a template specialization type. This becomes the TypeForDecl of the pattern declaration, which cleans up some amount of code (and complicates some other parts, but whatever). Fixes PR6326 and probably a few others, primarily by re-establishing a few invariants about TypeLoc sizes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98134 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-31Add VarDecl::isThisDeclarationADefinition(), which properly encapsulates the ↵Sebastian Redl
logic for when a variable declaration is a (possibly tentativ) definition. Add a few functions building on this, and shift C tentative definition handling over to this new functionality. This shift also kills the Sema::TentativeDefinitions map and instead simply stores all declarations in the renamed list. The correct handling for multiple tentative definitions is instead shifted to the final walk of the list. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94968 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22(1) Rename getClangSubversionRevision() to getClangRevision(), andTed Kremenek

There are couple of remaining issues that I would like for Ted. and Doug to look at: Ted, please look at failure in Analysis/MissingDealloc.m. I have temporarily added an expected-warning to make the test pass. This tests has a declaration of 'SEL' type which may not co-exist with the new changes.

2009-11-11Redo how PCH handles its implicit include. Instead of treating this specially inDaniel Dunbar
the front-end (as far as the preprocessor goes), follow the usual logic of inserting the (original include path) name into the predefines buffer. This pushes the responsibility for handling this to PCH instead of the front-end. In PCH this requires being a little more clever when we diff the predefines buffers. Neither of these solutions are particularly great, I think what we eventually should do is something like gcc where we insert a special marker to indicate the PCH file, but then run the preprocessor as usual. This would be clearer and would allow us to drop the overly clever predefines handling. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86806 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-11Rewrite splitLines using StringRef; this is much simpler, and also now avoidsDaniel Dunbar
tons of std::string trashing. I plan to move this and other fun string munging utilities to a StringRefExtras.h at some point if no one beats me to it. On a synthetic benchmark on x86_64, llvm-gcc actually generates code thats 10% faster using the StringRef version. gcc miscompiles the synthetic benchmark, which I'm crossing my fingers and hoping won't happen here. clang compiles the sythetic benchmark correctly (wootness), but the StringRef version is slower. Silly clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86799 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-11Introduce a new representation for template templateDouglas Gregor
parameters. Rather than storing them as either declarations (for the non-dependent case) or expressions (for the dependent case), we now (always) store them as TemplateNames. The primary change here is to add a new kind of TemplateArgument, which stores a TemplateName. However, making that change ripples to every switch on a TemplateArgument's kind, also affecting TemplateArgumentLocInfo/TemplateArgumentLoc, default template arguments for template template parameters, type-checking of template template arguments, etc. This change is light on testing. It should fix several pre-existing problems with template template parameters, such as: - the inability to use dependent template names as template template arguments - template template parameter default arguments cannot be instantiation However, there are enough pieces missing that more implementation is required before we can adequately test template template parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86777 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-23Fix integer overflow in PCHReader when reading the length of anTed Kremenek
identifier. This caused a crash when reading PCH files that contained long identifier names. The issue is that 'StrLenPtr' was previously a 'const char *', meaning the byte loaded from it would be interpretted as a signed integer. If the topmost bit was set, conversion to 'unsigned' would extend that bit, causing an overflow. The solution is to make 'StrLenPtr' an 'unsigned char *', always treating the value as an unsigned integer.
