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
