186e6683b0 type_traits: Implement is_member_object_pointer, is_member_function_pointer. 
2004-12-24  Paolo Carlini  <pcarlini@suse.de>

	* include/tr1/type_traits: Implement is_member_object_pointer,
	is_member_function_pointer. N.B. Due to c++/19076, the latter
	doesn't really work at the moment (a rather ugly work around
	will be provided in case the front-end bug doesn't get fixed
	soon); generalize and extend the _DEFINE_SPEC macros.
	* testsuite/tr1/4_metaprogramming/composite_type_traits/
	is_member_pointer/is_member_pointer.cc: New.
	* testsuite/tr1/4_metaprogramming/composite_type_traits/
	is_member_pointer/typedefs.cc: Likewise.
	* testsuite/tr1/4_metaprogramming/primary_type_categories/
	is_member_function_pointer/is_member_function_pointer.cc: Likewise.
	* testsuite/tr1/4_metaprogramming/primary_type_categories/
	is_member_function_pointer/typedefs.cc: Likewise.

ac3bfd867b re PR tree-optimization/14638 (Variables disappear from debug info at -O1) 
2004-12-24  Daniel Berlin  <dberlin@dberlin.org>

	Fix PR debug/14638

	* tree.h (DECL_DEBUG_ALIAS_OF): New macro.
	* var-tracking.c (track_expr_p): Don't disqualify tracking of variables
	that are aliases of variables we want to track, unless the
	original variable is also ignored for debugging purposes.
	(VARIABLE_HASH_VAL): Use DECL_UID, so that this is deterministic.
 	* tree-outof-ssa.c (create_temp): Note who we are a debug alias of.
	* dwarf2out.c (dwarf2out_var_location): Add us to the location of
	the decl we are an alias of.
