an argument. Also reinstall real name on unchecked
overriding/hiding methods for error report.

(patch_method_invocation_stmt): Local variable CLASS_TYPE
removed. Reverse method's argument when primary is a type. Don't
use CLASS_TYPE to report problems, use IDENTIFIER_WFL
instead. Include abstract class in the list of class searchable
for constructors. Use DECL_CONTEXT of found method for access
checks. Check method deprecation.
(patch_invoke): Pay extra care to NEW_CLASS_EXPR type call when
converting arguments. Handle INVOKE_INTERFACE.
(lookup_method_invoke): Search constructor using existing
infrastructure (don't rely on lookup_java_constructor anymore).

LC. Now include constructor in the search.
(qualify_ambiguous_name): Conditional expression are primaries.
(not_initialized_as_it_should_p): static final are always
initialized.
(java_complete_tree): Pass extra NULL argument to
resolve_expression_name. Stricter test to carry on patching
assignments. New case for INSTANCEOF_EXPR.
(complete_function_arguments): Inline PRIMTYPE.TYPE read access.
(check_final_assignment, maybe_build_primttype_type_ref): New
functions.
(patch_assignment): Detect resolved static finals and carry normal
assignment error check on them. Inline PRIMTYPE.TYPE read access.

types.

types. Accept all promoted type on int type.

assigned to a reference.
(valid_method_invocation_conversion_p): Accept to check null
pointers.
(build_binop): Merge declaration and initialization of local
variable BINOP.
(patch_binop): New case for INSTANCEOF_EXPR. NE_EXPR to accept all
numeric types. Improved validity test for qualify operators on
references.
(patch_unaryop): Broadened rejection test for PREDECREMENT_EXPR
and PREINCREMENT_EXPR. Also detect resolved static finals of a
primitive type and issue the appropriate error message.
(resolve_type_during_patch): Mark class loaded when resolved.
(patch_cast): Allow null to be cased to reference types.
(build_null_of_type): New function.
(patch_array_ref): Handle array on references correctly.
(patch_return): Removed unused local variable MODIFY. Force
boolean to be returned as integers. Allows null to be returned by
a function returning a reference.
* typeck.c (convert_to_integer, convert_to_real,
convert_to_pointer): Prototypes moved to convert.h
(lookup_argument_method): Use method real name, if necessary.
This improves method checking, gets rid of a cross file type
dependency bug and does a more robust job at laying out classes when
necessary. It unifies the regular methods and constructors lookup. It
implements the `instanceof' operator and interface method
invocations. It also fixes random bugs.
