+
+ * 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"
