2008-09-09Tweak implementation for allowing ObjC builtin type redefinitions.Steve Naroff
- Replace string comparisons with pre-defined idents. - Avoid calling isBuiltinObjCType() to avoid two checks. - Remove isBuiltinObjCType(), since it was only used in Sema::MergeTypeDefDecl(). - Have Sema::MergeTypeDefDecl() set the new type. This is a moidified version of an patch by David Chisnall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55990 91177308-0d34-0410-b5e6-96231b3b80d8

2008-09-05Change struct forward declarations and definitions to use unique ↵Ted Kremenek
RecordDecls, as opposed to creating a single RecordDecl and reusing it. This change effects both RecordDecls and CXXRecordDecls, but does not effect EnumDecls (yet). The motivation of this patch is as follows: - Capture more source information, necessary for refactoring/rewriting clients. - Pave the way to resolve ownership issues with RecordDecls with the forthcoming addition of DeclGroups. Current caveats: - Until DeclGroups are in place, we will leak RecordDecls not explicitly referenced by the AST. For example: typedef struct { ... } x; The RecordDecl for the struct will be leaked because the TypedefDecl doesn't refer to it. This will be solved with DeclGroups. - This patch also (temporarily) breaks CodeGen. More below. High-level changes: - As before, TagType still refers to a TagDecl, but it doesn't own it. When a struct/union/class is first referenced, a RecordType and RecordDecl are created for it, and the RecordType refers to that RecordDecl. Later, if a new RecordDecl is created, the pointer to a RecordDecl in RecordType is updated to point to the RecordDecl that defines the struct/union/class. - TagDecl and RecordDecl now how a method 'getDefinition()' to return the TagDecl*/RecordDecl* that refers to the TagDecl* that defines a particular enum/struct/class/union. This is useful from going from a RecordDecl* that defines a forward declaration to the RecordDecl* that provides the actual definition. Note that this also works for EnumDecls, except that in this case there is no distinction between forward declarations and definitions (yet). - Clients should no longer assume that 'isDefinition()' returns true from a RecordDecl if the corresponding struct/union/class has been defined. isDefinition() only returns true if a particular RecordDecl is the defining Decl. Use 'getDefinition()' instead to determine if a struct has been defined. - The main changes to Sema happen in ActOnTag. To make the changes more incremental, I split off the processing of enums and structs et al into two code paths. Enums use the original code path (which is in ActOnTag) and structs use the ActOnTagStruct. Eventually the two code paths will be merged, but the idea was to preserve the original logic both for comparison and not to change the logic for both enums and structs all at once. - There is NO CHAINING of RecordDecls for the same RecordType. All RecordDecls that correspond to the same type simply have a pointer to that type. If we need to figure out what are all the RecordDecls for a given type we can build a backmap. - The diff in CXXRecordDecl.[cpp,h] is actually very small; it just mimics the changes to RecordDecl. For some reason 'svn' marks the entire file as changed. Why is CodeGen broken: - Codegen assumes that there is an equivalence between RecordDecl* and RecordType*. This was true before because we only created one RecordDecl* for a given RecordType*, but it is no longer true. I believe this shouldn't be too hard to change, but the patch was big enough as it is. I have tested this patch on both the clang test suite, and by running the static analyzer over Postgresql and a large Apple-internal project (mix of Objective-C and C). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55839 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-05Remove "NextDecl" from RecordDecl. This change touches many files that ↵Ted Kremenek
where RecordDecl or CXXRecordDecl was constructed, always with an argument of 'NULL' for the previous declaration. The motivation behind this change is that chaining the RecordDecls is simply unnecessary. Once we create multiple RecordDecls for the same struct/union/class, clients that care about all the declarations of the same struct can build a back map by seeing which Decls refer to the same RecordType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55821 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-22Rewrite type compatibility testing to do type merging rather than just Eli Friedman
testing compatibility. This is necessary for some constructs, like merging redeclarations. Also, there are some ObjC changes to make sure that typesAreCompatible(a,b) == typesAreCompatible(b,a). I don't have any ObjC code beyond the testsuite, so please tell me if there are any cases where this doesn't behave as expected. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@55158 91177308-0d34-0410-b5e6-96231b3b80d8

- Kill unnecessary #includes in .cpp files. This is an automatic sweep so some things removed are actually used, but happen to be included by a previous header. I tried to get rid of the obvious examples and this was the easiest way to trim the #includes in one fell swoop. - We now return to regularly scheduled development. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54632 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-04Finally fix PR2189. This makes a fairly invasive but important change toChris Lattner
move getAsArrayType into ASTContext instead of being a method on type. This is required because getAsArrayType(const AT), where AT is a typedef for "int[10]" needs to return ArrayType(const int, 10). Fixing this greatly simplifies getArrayDecayedType, which is a good sign. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54317 91177308-0d34-0410-b5e6-96231b3b80d8

of doing it directly. This is required for PR2189. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54102 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-26fix several problems with the protocol qualified id handling where id was ↵Chris Lattner
implicit. First, fix canonical type handling of these, since protocol qualified id's are always canonical. Next, enhance SemaType to actually make these when used (instead of int) allowing them to actually be used when appropriate. Finally remove a bunch of logic relating to the mishandling of canonical types with protocol-qual id's. This fixes rdar://5986251 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54083 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-30Make a few related changes:Chris Lattner
1) add a new ASTContext::getFloatTypeSemantics method. 2) Use it from SemaExpr.cpp, CodeGenTypes.cpp and other places. 3) Change the TargetInfo.h get*Format methods to return their fltSemantics byref instead of by pointer. 4) Change CodeGenFunction::EmitBuiltinExpr to allow builtins which sometimes expand specially and othertimes fall back to libm. 5) Add support for __builtin_nan("") to codegen, cases that don't pass in an empty string are currently lowered to libm calls. 6) Fix codegen of __builtin_infl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52914 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-28Fix for PR2501; this patch makes usual arithmetic conversions for Eli Friedman
