2009-03-12Implement template instantiation for builtin binary operatorsDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66835 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-12Driver: Add majority of driver-driver implementation.Daniel Dunbar
- Compare to driverdriver.c if bored; not completely fair since the driver gets a bit more code in other places to handle binding archs (for Xarch) but not completely unfair either. Fear not, extra Action classes will have a happy home for their vtables soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66817 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-12Add Diagnostic files for Frontend and move a couple errors over.Daniel Dunbar
- Notably, clang now exits with an error if it can't find a file. This flushed out a bug in the CGColorSpace.c test case. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66789 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-11Fix various problems with matching out-of-line definitions of staticDouglas Gregor
class members to the corresponding in-class declaration. Diagnose the erroneous use of 'static' on out-of-line definitions of class members. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66740 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-11Move most of the checking from ActOnCXXMemberDeclarator to other, more ↵Douglas Gregor
general routines. This is a step toward separating the checking logic from Declarators, which in turn is required for template instantiation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66734 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-11Implement basic template instantiation for fields. Reshuffle checkingDouglas Gregor
for FieldDecls so that the parser and the template instantiation make use of the same semantic checking module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66685 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-11Add basic, hackish support for instantiation of typedefs in a classDouglas Gregor
template. More importantly, start to sort out the issues regarding complete types and nested-name-specifiers, especially the question of: when do we instantiate a class template specialization that occurs to the left of a '::' in a nested-name-specifier? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66662 91177308-0d34-0410-b5e6-96231b3b80d8

but not in TableGen files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66616 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66614 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10reject invalid escape characters in extended-asm strings with a nice diagnostic.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66605 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Add type checking for tentative definitions at the end of theDouglas Gregor
translation unit. Thread the various declarations of variables via VarDecl::getPreviousDeclaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66601 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Extend the notion of active template instantiations to include theDouglas Gregor
context of a template-id for which we need to instantiate default template arguments. In the TextDiagnosticPrinter, don't suppress the caret diagnostic if we are producing a non-note diagnostic that follows a note diagnostic with the same location, because notes are (conceptually) a part of the warning or error that comes before them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66572 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Add pretty-printing for class template specializations, e.g.,Douglas Gregor
'struct A<double, int>' In the "template instantiation depth exceeded" message, print "-ftemplate-depth-N" rather than "-ftemplate-depth=N". An unnamed tag type that is declared with a typedef, e.g., typedef struct { int x, y; } Point; can be used as a template argument. Allow this, and check that we get sensible pretty-printing for such things. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66560 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Add a notion of "post-diagnostic hooks", which are callbacks attachedDouglas Gregor
to a diagnostic that will be invoked after the diagnostic (if it is not suppressed). The hooks are allowed to produce additional diagnostics (typically notes) that provide more information. We should be able to use this to help diagnostic clients link notes back to the diagnostic they clarify. Comments welcome; I'll write up documentation and convert other clients (e.g., overload resolution failures) if there are no screams of protest. As the first client of post-diagnostic hooks, we now produce a template instantiation backtrace when a failure occurs during template instantiation. There's still more work to do to make this output pretty, if that's even possible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66557 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66551 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Add FullSourceLoc::getDecomposedLoc.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66522 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Limit the template instantiation depth to some user-configurable valueDouglas Gregor
(default: 99). Beyond this limit, produce an error and consider the current template instantiation a failure. The stack we're building to track the instantiations will, eventually, be used to produce instantiation backtraces from diagnostics within template instantiation. However, we're not quite there yet. This adds a new Clang driver option -ftemplate-depth=NNN, which should eventually be generated from the GCC command-line operation -ftemplate-depth-NNN (note the '-' rather than the '='!). I did not make the driver changes to do this mapping. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66513 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66506 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-09Fix PR3766, a really nasty silent miscompilation case where we emittedChris Lattner
a warning and then threw away the AST. While I'm in there, tighten up the code to actually reject completely bogus cases (sending a message to a struct). We still allow sending a message to an int, which doesn't make sense but GCC allows it and is easy to support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66468 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-07Cleanup/comment IdentifierInfo::get.Daniel Dunbar
- Shaves off a few instructions on x86_64. One notable change: this intentionally stops setting the II->Entry field of IdentifierInfo's retrieved by the ExternalLookup method. This is to maintain the invariant that .getName() has a constant value for any given IdentifierInfo. IRgen currently relies on this; which is quite questionable but will be cleaned up in time. Apologies for the lack of a test case; there really isn't a good way to make one. As IRgen will eventually be fixed to not rely on this, we can survive without one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66316 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-07Selector: (changes made after discussing this more with Steve Naroff)Ted Kremenek
- Make Selector::getAsIdentifierInfo() private. Using IdentifierInfo* in Selector is an implementation detail that clients shouldn't think about. - Modify diagnostic emission in Sema::ProcessPropertyDecl to not use Selector::getAsIdentifierInfo() (which could crash when IdentifierInfo* is null) and instead use Selector::getAsString(). - Tidy up Selector::getAsString() implementation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66313 91177308-0d34-0410-b5e6-96231b3b80d8
