* cp-demangle.c (d_bare_function_type): Recognize new 'J' qualifer
and include return type when found.
(d_print_comp)[DEMANGLE_COMPONENT_FUNCTION_TYPE]: Add
conditional logic to change printing order of return type.when
the DMGL_RET_POSTFIX option is present.
(java_demangle_v3): Add DMGL_RET_POSTFIX option to d_demangle
call.
* testsuite/test-demangle.c (main): Recognize option --ret-postfix
* testsuite/demangle-expected: Test cases to verify extended encoding.
Updated comment to document --ret-postfix option.
2005-11-06 Richard Guenther <rguenther@suse.de>
* splay-tree.c (rotate_left): New function.
