* core.c (dis_asm_read_memory): Add call to
dis_asm_read_memory_hook to provide alternate way for disassembler
to read memory.
* defs.h: Protect from multiple inclusion. Add decl for
dis_asm_read_memory_hook.
* gdbtk.c (finish_saving_output): Don't do anything if not saving
output.
* (breakpoint_notify): Don't send null filename to tcl.
* (gdb_eval): New tcl command to eval an expression.
* (gdb_disassemble): New tcl command to do disassembly. This
allows tcl code to choose between exec file and target memeory,
and can also do mixed source and assembly.
* (gdbtk_init): Move reading of gdbtk.tcl to the end to make sure
that more of the environment is set up. Also, create link between
gdb and tcl vars disassemble{-_}from{-_}exec.
* gdbtk.tcl: New expression window support.
* Make assembly window be 80 columns wide.
* Use new disassembly method. Add menu items to select
disassembly from exec file or target.
* Change View menubar item to Options.
* Get rid of Stack, Breakpoints, Signals, and Variables Windows,
since they don't exist yet.
* Pop up a copyright window on startup.
* top.c: Make window startup be the default.
* Add dis_asm_read_memory_hook.
(tuple): Parse simple unlabelled tuples.
* eval.c (evaluate_subexp case OP_ARRAY): Use expect_type to
evaluate brace-initializer-expressions depending on context.
(evaluate_subexp case UNOP_CAST): Pass the target type as
expected type when evaluating the expression.
BOOL from TYPE_NAME.
* ch-valprint.c (chill_print_type_scalar): New function, to handle
TYPE_CODE_RANGE better than print_type_scalar does.
(chill_val_print_array_elements): Use above new function.
* read.c (s_space): Rewrite to handle general expressions. Generate rs_space
frags for non-constant values.
* write.c (cvt_frag_to_fill): Treat rs_align_code and rs_space like rs_align
and rs_org. Verify that fr_offset is non-negative, and force frag type to
rs_fill only after assertion checks.
(relax_segment): Treat rs_align_code like rs_align. Treat rs_space like rs_org
in the first switch; in the second, force the operand to a constant, and use it
for the growth size.
(relax_stateT): Separate typedef from enum definition.
(enum _relax_state): Reordered for better punctuation. Added new values
rs_align_code and rs_space.
(lineno, struct lineno_struct): Unused, deleted.
For friendlier assertion-failure messages:
* as.h: No longer include assert.h.
(as_assert): Declare.
(assert): New definition, calls as_assert longer needed.
(__PRETTY_FUNCTION__): Provide default for older versions of gcc.
* messages.c (as_assert): New function.
* gdbinit.in: Put a breakpoint there.
commands.
* top.c (struct user_args): Structure for holding arguments to
user defined commands.
(print_command_line): Delete unused "tmp_chain" variable. Clean
up flow control by having cases exit in the same manner.
Before executing a command or evaluating an expression, substitute
the current $arg0..$arg9 values if the command/expression uses them.
(arg_cleanup): New function.
(setup_user_args, locate_arg, insert_args): Likewise.
(execute_user_command): Allow arguments to user defined commands.
* Allow if/while commands to be used within a breakpoint command
list.
* breakpoint.c (bpstat_do_actions): Call execute_control_command
rather than execute_command (passes entire command structure rather
than just the command line text).
(breakpoint_1): Use "print_command_line" to print a breakpoint
command line (including control structures).
* gdbcmd.h (execute_control_command): Provide extern decl.
(print_command_line): Likewise.
* top.c (execute_control_command): No longer static.
(print_command_line): New function to recursively print a command
line, including control structures.
to monitor config structure for supported baud rates for a target
and variable stop bits.
* monitor.c (monitor_fetch_register): Store register values in big
endian format on any host.
([r|w][bwl]at[little|big]) New functions.
(sim_resume): If GO32 check for interrupt every now
and again. Decrement PC if SIGBUS seen.
* run.c (main): Return result of simulated _exit.
export stubs and actual shared library functions so that lazy
binding works correctly. Try both __d_plt_call and __gcc_plt_call
trampolines for calling import stubs.
space ID to place in the stack & inf_status structure.
(hppa_pop_frame): Don't walk through trampoline code if popping a
call dummy frame.
(hppa_fix_call_dummy): Call the stack dummy directly if the
current PC is in a shared library.
in_syscall bit in flags. Don't depend on the PC queue registers
when in_syscall is set, they're not valid.
* config/pa/tm-hppa.h (PUSH_DUMMY_FRAME): Pass inf_status down to
push_dummy_frame.
(SR4_REGNUM): Define.
* hppa-tdep.c: Misc. lint changes.
