Fri Jun 12 11:31:24 1998 Per Bothner <bothner@cygnus.com>
We used to have three different representations of the constant pool:
the CPool structure, the tree_constant_pool, and the constructures
used to build the Class object (which may need class and string
constants) in compiled code. None were appropriate for compiling
to .class files, so I did a major overhaul.
First, the tree_constant_pool array was removed. Things were
modified to the CPool structure in the JCF could be used.
Second, a "capacity" field was added to the CPool, and functions
written to search for a matching constant, adding one if not found.
The code that generated the Class object was changed to use a CPool.
The actual TREE_LISTs used to build the CONSTRUCTORs used for
the static Class object are now only in build_constants_constructor.
Finally, I wrote code which can generate a .class file (including its
constant pool) from the RECORD_TYPE of a class. This is a big step
on the way to compiling Java source into .class files.

not find_stack_slot. Call set_local_type.

* java-tree.h: Various new macros for constructing RECORD_TYPEs,
and building RECORD_TYPE CONSTRUCTORs.
Also support for creating Utf8Const objects from an INDETIFIER_NODE.
* lang.c (use_handles): Change the default to 0.
* decl.c: Define and build class_type, field_type, utf8const_type.
* class.c (make_class_data, make_field_value,
get_access_flags_from_decl, build_class_ref, build_utf8_ref,
hashUtf8String, strLengthUtf8, mangled_classname:
Functions to build reflective data structures.
* parse.c (yyparse): Call make_class_data.
* jcf-io.c (open_class, find_classfile): New functions.
* jcf-dump.c: Support reading classfile from explicitly-named
class file (without CLASSPATH searching).

* jcf-reader.c: Add parameter list to HANDLE_CONSTANT_Utf8.
* parse.c (JPOOL_UTF_LENGTH, JPOOL_UTF_DATA, HANDLE_CONSTANT_Utf8):
Override jcf-reader macros so CONSTANT_Utf8 becomes tree node here.
(get_constant): Now trivial for CONSTANT_Utf8.
* jcf.h: Make NEW_CPOOL the default.
* jcf.h, jcf-reader.c, parse.c: Remove support for !NEW_CPOOL.
