|
||||
|
||||
* blockframe.c (frameless_look_for_prologue): Speed up by
|
||||
calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
|
||||
* tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
|
||||
Define two variants, one faster.
|
||||
* sparc-tdep.c (sparc_frame_chain): Use target_read_memory
|
||||
and return zero, rather than giving an error.
|
||||
(setup_arbitrary_frame): Initialize the PC in the new frame.
|
||||
(skip_prologue): Add a second arg saying whether we're just
|
||||
checking for a frameless function or not.
|
||||
|
||||
* core.c (core_open, core_close, core_xfer_memory): Move
|
||||
section table pointers and bfd* into the target_ops.
|
||||
(core_open): Allow errors in shared lib reading, etc.
|
||||
(core_files_info): Describe shared library sections.
|
||||
|
||||
* exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
|
||||
exec_files_info, set_section_command): Move section table
|
||||
pointers and bfd* into the target_ops.
|
||||
(add_to_section_table): Add BFD to section table.
|
||||
|
||||
* target.c (target_xfer_memory, target_info): Pass target to
|
||||
xfer_memory and target_info functions.
|
||||
* target.h: ''
|
||||
|
||||
* gdbcore.h: Move struct section_table.
|
||||
* target.h: New home of struct section_table.
|
||||
|
||||
* solib.c (solib_add): New argument is the target_ops whose
|
||||
section list is to be added to, if any. Reallocate the
|
||||
sections in that target to add any that come from shared libs.
|
||||
(throughout) so_sections renamed to sections.
|
||||
(solib_xfer_memory): Deleted.
|
||||
* tm-sunos.h (SOLIB_ADD): Add target argument.
|
||||
(SOLIB_XFER_MEMORY): Delete.
|
||||
|
||||
* core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
|
||||
remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
|
||||
from target_ops. It's the same on all targets. Add two section
|
||||
pointers to target_ops.
|
||||
|
||||
* stack.c (find_relative_frame): Dump ancient algorithm for
|
||||
"down", just use handy "next" pointers.
|
||||
(frame_command): Don't error if there is no stack; let user
|
||||
set one.
|
||||
|
||||
* inflow.c (new_tty_prefork, new_tty): New prefork routine
|
||||
modifies static state in the parent process; new_tty itself
|
||||
runs in the child and modifies the child's file descriptors
|
||||
to match the saved static state.
|
||||
* infrun.c (child_create_inferior): Call new_tty_prefork,
|
||||
fork, then new_tty.
|
||||
|
||||
* infptrace.c (child_xfer_memory): Add ignored target arg.
|
||||
* remote-eb.c (eb_xfer_inferior_memory): ''
|
||||
* remote-nindy.c (nindy_xfer_inferior_memory): ''
|
||||
* remote-vx.c (vx_xfer_memory): ''
|
||||
* remote.c (remote_xfer_memory): ''. Rename from
|
||||
remote_xfer_inferior_memory.
|
||||
|
||||
* main.c (main): Only try to attach "corefile" argument if
|
||||
it starts with a digit.
|
||||
|
||||
* symfile.c (symbol_reloading): New "set/show" variable.
|
||||
(symbol_file_add): Shorten message about symbol reading.
|
||||
(add_symbol_file_command): Merge with add_syms_addr_command,
|
||||
since this should work on all targets now.
|
||||
(stop_whining): Default to zero, to shut up complaints
|
||||
about bad symbol tables on many systems.
|
||||
(free_named_symtabs): Just exit unless symbol_reloading.
|
||||
|
||||
* xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
|
||||
and add comment explaining shared library screw.
|
||||
|
||||
* source.c: #if defined => #ifdef.
|
||||
|
||||
Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
|
||||
|
||||
* doc/gdbint.texinfo: Improve doc on porting to new OS's.
|
||||
|
||||
Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
|
||||
|
||||
* Makefile: use doc/Makefile for doc targets
|
||||
* doc/rdl-apps.texinfo: provide default readline-appendix finder
|
||||
(doc/Makefile knows how to make one for local config)
|
||||
|
||||
* Makefile.in: use doc/Makefile for doc targets
|
||||
|
||||
* doc/Makefile: GDB documentation now has its own Makefile
|
||||
doc/refcard.tex: renamed from "gdbrc.tex"
