Devang Patel e03edfd3e7 Even if a constant's evaluated value is used, emit debug info for the constant variable.

Devang Patel c7f16ab3e3 Override selected builtin names (e.g. "long int" instead of "long") to match names used by gcc in debug info. This makes gdb testsuite happy.

Devang Patel 268ad093a7 Untangle filename/dirname confusion. Store constructed strings on the side. Avoid use of Path.makeAbsolute().
DW_TAG_compile_unit uses two attributes DW_AT_name and DW_AT_comp_dir. Their expected values are:

$ clang foo.c -g
  DW_AT_name - foo.c
  DW_AT_comp_dir - `pwd`

$ clang one/two/foo.c -g
  DW_AT_name - one/two/foo.c
  DW_AT_comp_dir - `pwd`

$ clang /tmp/one/foo.c -g
  DW_AT_name - /tmp/one/foo.c
  DW_AT_comp_dir - empty

2010-07-23 23:04:28 +00:00
Devang Patel 28f167699a There is no need to use separate dir name for AT_comp_dir attribute. Using absolute path for filename allows clients to query complete file location info from gdb breakpoints. Save constructed full file name.

Devang Patel 0884a60eb5 Keep track of artificial scopes introduced by line directives. For example,
#line 41 "bar.c"
  dummy (1, i);
#line 24 "bar.h"
  i = f2 (i);
#line 44 "bar.c"

This is tested by step-line.exp in gdb testsuite.

John McCall 8b07ec253d Substantially alter the design of the Objective C type AST by introducing
ObjCObjectType, which is basically just a pair of
  one of {primitive-id, primitive-Class, user-defined @class}
with
  a list of protocols.
An ObjCObjectPointerType is therefore just a pointer which always points to
one of these types (possibly sugared).  ObjCInterfaceType is now just a kind
of ObjCObjectType which happens to not carry any protocols.

Alter a rather large number of use sites to use ObjCObjectType instead of
ObjCInterfaceType.  Store an ObjCInterfaceType as a pointer on the decl rather
than hashing them in a FoldingSet.  Remove some number of methods that are no
longer used, at least after this patch.

By simplifying ObjCObjectPointerType, we are now able to easily remove and apply
pointers to Objective-C types, which is crucial for a certain kind of ObjC++
metaprogramming common in WebKit.

Devang Patel c5ffabc94f If given location is invalid then use current location.

Douglas Gregor c8be95274d When instantiating a function that was declared via a typedef, e.g.,
typedef int functype(int, int);
    functype func;

also instantiate the synthesized function parameters for the resulting
function declaration. 

With this change, Boost.Wave builds and passes all of its regression
tests.

John McCall 2408e32096 Make the InjectedClassNameType the canonical type of the current instantiation
of a class template or class template partial specialization.  That is to
say, in
  template <class T> class A { ... };
or
  template <class T> class B<const T*> { ... };
make 'A<T>' and 'B<const T*>' sugar for the corresponding InjectedClassNameType
when written inside the appropriate context.  This allows us to track the
current instantiation appropriately even inside AST routines.  It also allows
us to compute a DeclContext for a type much more efficiently, at some extra
cost every time we write a template specialization (which can be optimized,
but I've left it simple in this patch).
