Dwarf 2 Minutes, April 18, 2000

Issue discussion --

000323.1	Java LANG definition

	Add DW_LANG_Java definition.  Approved.

000323.2	Java Interface definition

	Add DW_TAG_interface_type for Java support.  Approved.  
	Interface is semantically equivalent to class or struct.  A Java 
	interface is equivalent to an abstract class in C++.  Discussion 
	about whether to create new tag or to use struct resulted in decision 
	to create new TAG rather than reuse DW_TAG_struct.  Struct, class and 
	union are separate TAGs, even if the semantic differences between struct 
	and class are minimal. Only the following attributes are expected:  
	DECL (standard source location), DW_AT_accessibility, DW_AT_name, 
	DW_AT_sibling, and DW_AT_start_scope. 

000330.1	Call Frame extension

	Extend CFA computation to make it more general.  The PowerPC Altivec
	function prolog dynamically aligns the stack by inserting alignment
	bytes.  Current CFA only permits static description of stack frame.
	Add DW_CFA_def_cfa_expression and DW_CFA_expression to allow general
	computation of arbitrary expression.  Approved.
