* Add support for C++ default arguments, and rework Parse-Sema Chris Lattner2008-04-081-61/+163
| | | | | | | | interaction for function parameters, fixing PR2046. Patch by Doug Gregor! llvm-svn: 49369

| | | | | | | | Context.getCanonicalType(CT) for PR2189. While I'm at it, clean up a bit of maxIntegerType. llvm-svn: 49292
* This patch contains these changes:Chris Lattner2008-04-061-9/+9
| | | | | | | | | | -Renamed ContextDecl -> DeclContext -Removed DeclContext pointer from FieldDecl -EnumDecl inherits from DeclContext, instead of TagDecl Patch by Argiris Kirtzidis! llvm-svn: 49261
* Add explicit support for diagnosing implicit function decls.Steve Naroff2008-04-041-3/+11
| | | | | | Without this, the diagnostic is very confusing. The diag is now consistent with gcc as well. llvm-svn: 49214
* Introduce ContextDecl, patch by Argiris Kirtzidis!Chris Lattner2008-04-041-13/+33
| | | | | | | | | | | -Added ContextDecl (no TranslationUnitDecl) -ScopedDecl class has a ContextDecl member -FieldDecl class has a ContextDecl member, so that a Field or a ObjCIvar can be traced back to their RecordDecl/ObjCInterfaceDecl easily -FunctionDecl, ObjCMethodDecl, TagDecl, ObjCInterfaceDecl inherit from ContextDecl. With TagDecl as ContextDecl, enum constants have a EnumDecl as their context. -Moved Decl class to a "DeclBase.h" along with ContextDecl class -CurContext is handled by Sema llvm-svn: 49208
* Change ObjCInterfaceDecl to inherit from NamedDecl (not TypeDecl). While ↵Steve Naroff2008-04-021-12/+7
| | | | | | | | ObjCInterfaceDecl is arguably a TypeDecl, it isn't a ScopedDecl. Since TypeDecl's are scoped, it makes sense to simply treat them as NamedDecl's. I could have fiddled a bit more with the hierarchy (in terms of creating a non-scoped TypeDecl), however this probably isn't worth the effort. I also finished unifying access to scope decl change by converting Sema::getObjCInterfaceDecl() to use Sema::LookupDecl(). This is much cleaner now:-) llvm-svn: 49107
* Two changes to Sema::LookupDecl() interface. Steve Naroff2008-04-021-34/+18
| | | | | | | | | | | (1) Remove IdLoc (it's never used). (2) Add a bool to enable/disable lazy builtin creaation (defaults to true). This enables us to use LookupDecl() in Sema::isTypeName(), which is also part of this commit. To make this work, I changed isTypeName() to be a non-const member function. I'm not happy with this, however I fiddled with making LookupDecl() and friends const and it got ugly pretty quickly. We can certainly add it back if/when someone has time to fiddle with it. For now, I thought this simplification was more important than retaining the const-ness. llvm-svn: 49087
* Fix several bugs in array -> pointer decomposition.Chris Lattner2008-04-021-3/+2
| | | | | | | | | | | | | | | | First, we got several CVR propagation cases wrong, which Eli pointed out in PR2039. Second, we didn't propagate address space qualifiers correctly, leading to incorrect lowering of code in CodeGen/address-space.c. Third, we didn't uniformly propagate the specifier in the array to the pointer ("int[restrict 4]" -> "int *restrict"). This adds an ASTContext::getArrayDecayedType member that handles the non-trivial logic for this seemingly simple operation. llvm-svn: 49078

* Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass ↵Steve Naroff2008-04-011-37/+44
| | | | | | | | | | | | | (to inherit from NamedDecl, instead of ScopedDecl). - Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl. - Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's. - Removed Sema::LookupInterfaceDecl(). Converted clients to used LookupDecl(). - Some minor indentation changes. Will deal with ObjCInterfaceDecl and getObjCInterfaceDecl() in a separate commit... llvm-svn: 49058

lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. llvm-svn: 48402
