* target.h: Comments on target_attach args and results. * infcmd.c (attach_command): Check for existing execution, call target_attach, set up terminal status and wait_for_inferior, wait for the attach status, and do normal_stop. * inftarg.c (child_attach): Remove target independent stuff. * remote-adapt.c (adapt_attach): Ditto. * remote-mm.c (mm_attach): Ditto. * remote-udi.c (udi_attach): Ditto. * remote-vx.c (vx_attach): Ditto.

(resume): becomes global so that functions below the target vector can find it. * inferior.h (resume): add prototype. (child_mourn_inferior, child_create_inferior, child_attach): remove prototypes.
1992-09-25 * xcoffexec.c (exec_ops): child_attach and child_create_inferiorK. Richard Pixley2-3/+13

1992-09-22Describe coding style of GDB.John Gilmore1-0/+4
1992-09-22Break the thread of control that implies that a unix childJohn Gilmore12-2/+39

through the target vector. * inferior.h (kill_inferior_fast): remove declaration. * main.c (disconnect): call quit_cover using catch_errors rather than calling kill_inferior_fast directly. New way goes through the target vector, handles attached processes, and writes command history if appropriate.

of their dreams.
1992-09-20 * main.c (main): Back out previous language setting changes.Fred Fish2-9/+12
Replace with simple default to C before processing any init files. There MUST be a language set, even in the absence of init files or executables, or expression parsing fails.
1992-09-19 * main.c (main): Move code that sets initial language toFred Fish2-30/+34
symfile.c. Fixup places where command files are processed to be consistent in setting a default language if none has been previously set. * symfile.c (set_initial_language): Add code moved from main() that sets an initial default language when a new symbol file is read. * symfile.c (symbol_file_command): Call set_initial_language. * symtab.c (find_main_psymtab): Add FIXME comment.
1992-09-19* rs6000-tdep.c (push_dummy_frame, pop_dummy_frame): replaceJohn Gilmore2-4/+8

1992-09-19* configure.in: removed target_dependent line.John Gilmore4-3/+8
* remote-mm.c (mm_attach): change printf to error to prevent fallthrough bug. * remote-udi.c (udi_attach): change printf to error to prevent fallthrough bug.

1992-09-19* Makefile.in: Fix bug I introduced in merging Rich's change.John Gilmore2-96/+173
* infrun.c (child_create_inferior): Use proceed() rather than doing all the same stuff by hand.
1992-09-19* Makefile.in, configure.in: add support for files used only whenJohn Gilmore3-17/+40
configured native, that is, when host == target.
1992-09-19* tm-sparc.h, xm-sparc.h: externs and macros relating to deferredJohn Gilmore3-14/+20
stores are target dependent and were moved from xm to tm.
1992-09-19* Makefile.in (gdb-all.texi): Build in objdir, not $srcdir.John Gilmore2-1/+3
1992-09-19* config/decstation.mh: Add MMALLOC_LIB and MMALLOC_DISABLEJohn Gilmore2-0/+11
overrides, to avoid problem in xdr_bytes with malloc(0) => 0.
1992-09-18Patched a couple of minor bugs in UDI support. These have been sentIan Lance Taylor1-1/+1
to AMD.
1992-09-18Remove convert_{to,from}_virtual members from target structs.John Gilmore13-29/+28
1992-09-18* target.h (struct target_ops): removed to_convert_to_virtual andJohn Gilmore4-95/+88
to_convert_from_virtual elements. Initializations removed from all static initializations. (target_convert_to_virtual, target_convert_from_virtual): removed. (host_convert_to_virtual, host_convert_from_virtual): Removed forward declarations. * target.c (cleanup_target): removed default assignments for to_convert_to_virtual and to_convert_from_virtual. * inftarg.c (host_convert_to_virtual, host_convert_from_virtual): removed. * findvar.c (value_of_register, value_from_register): target_convert_to_virtual inlined. * infcmd.c (do_registers_info): target_convert_to_virtual inlined. * valops.c (value_assign): target_convert_from_virtual inlined.
1992-09-18* main.c (gdb_readline): Avoid printf_filtered, which sets charJohn Gilmore2-1/+8
position wrong if used for the prompt. * utils.c (puts_filtered): Comment: NOT a puts() replacement!
1992-09-18Support for accessing arbitrary MIPS stack frames in memory.John Gilmore3-0/+58
* blockframe.c (get_prev_frame_info): If INIT_FRAME_PC_FIRST is set, run it before INIT_EXTRA_FRAME_INFO. * stack.c (frame_info): If PRINT_EXTRA_FRAME_INFO defined, call it. * mips-tdep.c (init_extra_frame_info): Only clobber the `frame' (FP) value in the frame_info struct if it is zero (as from top of execution stack). (setup_arbitrary_frame): Implement FRAME_SPECIFICATION_DYADIC. * mips-xdep.c (fetch_inferior_registers): ZERO_REGNUM always comes back as zero. So does FP_REGNUM, as a trigger for init_extra_frame_info. * tm-mips.h (INIT_FRAME_PC_FIRST): Kludge, FIXME, defined to get the program counter set before INIT_EXTRA_FRAME_INFO is run. (INIT_FRAME_PC): Defined to null. (PRINT_EXTRA_FRAME_INFO): print frame pointer location via symtab. (FRAME_SPECIFICATION_DYADIC): Ask for two args in frame command. Briefly explain MIPS stacks in GDB.
1992-09-18* tm-rs6000.h (AIX_BUGGY_PTRACE_CALL): Zap, we think we fixed it.John Gilmore3-19/+7
Rich and I believe the "real problem" was that both single_step and target_resume were issuing PT_CONTINUE calls. This would cause the second PT_CONTINUE to sometimes fail because the process was already running. * infptrace.c (child_resume): Remove AIX_BUGGY_PTRACE_CALL kludge.
1992-09-18Preliminary cleanup for splitting host/native/target.John Gilmore3-12/+19
* infptrace.c (child_resume): Don't deal with NO_SINGLE_STEP here; it is dealt with at a gdb-target-independent level. * rs6000-tdep.c (single_step): Don't call ptrace, we are a high toned routine. Fix return type to void.
1992-09-18* Makefile.in (update-depend, update-alldeps): Split out ofJohn Gilmore2-11/+29
setup-to-dist, for convenience in rebuilding the depend and alldeps.mak files. (assorted): Update to catch straggler files when building gdb.tar.Z
1992-09-17Improve release doc slightly.John Gilmore2-3/+8
1992-09-17* copying.awk, copying.c (show_copying_command,John Gilmore1-0/+4
show_warranty_command): Rename from copying_info, warranty_info, to match command function conventions.
