David Taylor b98e2024f4 The following changes were made by
Elena Zannoni <ezannoni@kwikemart.cygnus.com>,
	David Taylor <taylor@texas.cygnus.com>, and
	Edith Epstein <eepstein@sophia.cygnus.com> as part of a project to
	merge in changes by HP; HP did not create ChangeLog entries.

	* dis-buf.c (generic_strcat_address): new function.

	* hppa-dis.c: Changes to improve hppa disassembly.
	  Changed formatting in : reg_names, fp_reg_names,control_reg,
	  New variables : sign_extension_names, deposit_names, conversion_names
	    float_test_names, compare_cond_names_double, add_cond_names_double,
	    logical_cond_names_double, unit_cond_names_double,
	    branch_push_pop_names, saturation_names, shift_names, mix_names,
	  New Macros :   GET_COMPL_O, GET_PUSH_POP,MERGED_REG
	  Move some definitions to libhppa.h: GET_FIELD, GET_BIT
	  (fput_const): renamed as fput_hex_const
	  (print_insn_hppa):
	   - use the macros fputs_filtered and
	     fput_decimal_const whenever possible; calls to sign_extend require
	     2 params -- add a missing second param of 0.
	   - Some new code ifdefed for LOCAL_ONLY, all related to figuring out
	     architecture version number of current machine. HP folks are
	     trying to handle situation where the target program was compiled
	     for PA 1.x (32-bit), but is running on a PA 2.0 machine and
	     visa versa.
	   - added new cases : 'g', 'B', 'm'
	   - added cases specifically for PA 2.0
	   - changed the following cases : '"', 'n', 'N', 'p', 'Z',
	   - calls to fput_const become calls to fput_hex_const
