Make Sparc a Multi-Arch target. Discard PARAMS macro (require ANSI). * sparc-tdep.c: include arch-utils.h. (SPARC_HAS_FPU, FP_REGISTER_BYTES, FP_MAX_REG NUM, SPARC_INTREG_SIZE, DUMMY_REG_SAVE_OFFSET): provide multi-arch-compatible definitions. (GDB_TARGET_IS_SPARC64): make into a runtime test. (struct frame_extra_info): Define, use instead of the macro. (Many places): Use alloca instead of statically allocated buffers that depend on a multi-arch variable such as MAX_REGISTER_RAW_SIZE. (sparc_extract_struct_value_address): Accept a pointer arg instead of an array sized by REGISTER_BYTES. (examine_prologue): Accept a pointer to an array of CORE_ADDR, instead of the defunct struct frame_saved_regs. Recognize new Sparc64 store instructions as part of the prologue. Ignore the destination of a frame store when parsing the prologue (so long as it's on the stack). (sparc_push_dummy_frame): Fix incorrect buffer offset for PSTATE. (sparc_frame_find_saved_regs): Accept a ptr to an array of CORE_ADDR instead of the defunct struct frame_saved_regs. (supply_gregset): Discard unnecessary 'zerobuf': just send NULL to supply_register. Provide 4-byte offset to compensate for diff between size of the prgreg_t elements on a 64-bit host and size of the registers for a 32-bit target. Fill all inaccessible regs with zero so they won't keep being requested again and again. (fill_gregset): Handle 32/64 size difference between registers and prgreg_t. Handle as many new 64-bit regs as possible. (supply_fpregset, fill_fpregset): Attempt to handle 64-bit world. (sparc_push_arguments): Rename to sparc32_push_arguments. Copy arguments into registers as well as onto stack, so that the CALL_DUMMY (code pushed onto the target stack) is not required. (sparc_extract_return_value): Rename to sparc32_extract_return_value. (sparc_store_return_value): Use memset instead of bzero. Use write_register_gen instead of write_register_bytes. (sparclet_store_return_value): New function. (_initialize_sparc_tdep): Call register_gdbarch_init to activate the gdbarch multi-architecture system. (sp64_push_arguments): Rename to sparc64_push_arguments. Extend to store arguments in general registers as well as on stack. (sparc64_extract_return_value): Rename to sp64_extract_return_value. Use as a private function, to be called by the new external function sparc64_extract_return_value. (sparclet_extract_return_value): New function. (sparc32_stack_align, sparc64_stack_align, sparc32_register_name, sparc64_register_name, sparc_print_extra_frame_info, sparclite_register_name, sparclet_register_name, sparc_push_return_address, sparc64_use_struct_convention, sparc32_store_struct_return, sparc64_store_struct_return, sparc32_register_virtual_type, sparc64_register_virtual_type, sparc32_register_size, sparc64_register_size, sparc32_register_byte, sparc64_register_byte, sparc_gdbarch_skip_prologue, sparc_convert_to_virtual, sparc_convert_to_raw, sparc_frame_init_saved_regs, sparc_frame_address, sparc_gdbarch_fix_call_dummy, sparc_coerce_float_to_double, sparc_call_dummy_address, sparc_y_regnum, sparc_reg_struct_has_addr, sparc_intreg_size, sparc_return_value_on_stack): New functions supporting multi-arch. (sparc_gdbarch_init): New function; initialize multi-arch. (struct gdbarch_tdep): Define, use for private multi-arch data. * config/sparc/tm-sparc.h: Move definitions around, enclose with #ifdef GDB_MULTI_ARCH tests, provide some multi-arch alternate definitions. Add enums for register names, to help debugging gdb. This header file must work for non-multi-arch and for multi-arch. * config/sparc/tm-sp64.h: Add GDB_MULTI_ARCH configuration. Also add AT_ENTRY_POINT definitions for CALL_DUMMY, for non-multi-arch case. Define GDB_MULTI_ARCH. * config/sparc/tm-sparclet.h: Add GDB_MULTI_ARCH configuration. Do not define GDB_MULTI_ARCH (bfd does not correctly identify target). * config/sparc/tm-sparclite.h: Ditto. * config/sparc/tm-sun4sol2.h: Define GDB_MULTI_ARCH. * sparclet-rom.c (sparclet_regnames): Initialize explicitly, to avoid using deprecated REGISTER_NAMES macro. * Makefile.in: Let sparc-tdep.c depend on arch-utils.h. |

README
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
