+Thu Dec 31 12:08:32 1998 David Taylor <taylor@texas.cygnus.com>
+
+ The following changes were made by Jim Blandy <jimb@cygnus.com>,
+ Edith Epstein <eepstein@cygnus.com>, Elena Zannoni
+ <ezannoni@cygnus.com> Stan Shebs <shebs@cygnus.com>, and David
+ Taylor <taylor@cygnus.com>, as part of the project to merge in
+ changes originally made by HP; HP did not create ChangeLog
+ entries.
+
+ * Makefile.in: New file; we're merging HP's changes into GDB, and
+ we've moved the TUI files into a subdirectory, so we need a new
+ Makefile.
+
+ * tui.c:
+ #include <term.h>, if we have it, to get declarations for
+ the termcap functions on Solaris.
+ (tgoto): Add external K&R declaration for this; Solaris doesn't
+ bother to actually declare it in their header files.
+ (_tuiReset): Ignore the #definition of TIOCGETC if USG is defined;
+ we'd rather use the USG mechanisms than the Berkeley mechanisms
+ (TIOCGETC is one of the Berkeley terminal control ioctls).
+ Apologies if this causes trouble later; this should all be handled
+ by autoconf...
+ (strcat_to_buf, strcat_to_buf_with_fmt): New functions, moved here
+ from ../utils.h.
+ (tuiFree): replace safe_free with free.
+ (strcat_to_buf): new function, copied from utils.c.
+ (tuiInit): Add ignored `argv0' argument, to match the type that
+ init_ui_hook expects; updated declaration. Call the
+ initialize_tui_files function constructed above. Initialize
+ flush_hook to NULL.
+ (tuiInitWindows): Call tuiSetLocatorContent, to get the first
+ element of the locator window's content allocated. This seems
+ wrong, because it must have been initialized somehow in HP's
+ sources, and we should do it the same way now. But we do get
+ further before it segfaults. [Postscript: HP didn't bother to
+ initialize it; they compile
+ (va_catch_errors, vcatch_errors): Functions moved here from
+ ../utils.c in HP's sources. They're not used anywhere else.
+ (xdb_style): Delete this variable, and remove all references to
+ it. It's always true.
+ (tuiInit, _tui_vDo): References removed.
+
+ * tui.h: Add prototypes.
+ Don't #include "gendefs.h"; it's only used in the TUI.
+ Integrate its contents into this file:
+ #include <ansidecl.h> here.
+ (Opaque, OpaqueFuncPtr): Typedefs moved to here.
+
+ * tuiCommand.c: #include "defs.h", so we get the appropriate
+ definition of GDB_FILE.
+
+ * tuiData.c
+ (freeWindow): replace safe_free with free.
+ (tui_version): don't define it here; it's defined in main.c now.
+
+ * tuiDisassem.c
+ (tuiSetDisassemContent): Call strcat_address_numeric instead of
+ strcat_address. Simplify the control structure. Use predefined
+ GDB function to print asm inst address. Use GDB_FILE to collect
+ output into buffers.
+
+ * tuiIO.c
+ (tgoto): Add external K&R declaration for this here too.
+ (tuiGetc, tuiTermSetup, tuiTermUnsetup): Same.
+ (tuiPuts_unfiltered): change FILE to GDB_FILE.
+ (tui_tputs): fix prototype for 3rd argument.
+
+ * tuiIO.h (tuiPuts_unfiltered): change declaration.
+
+ * tuiLayout.c
+ (_tuiSetLayoutTo): for displaying registers, hook up the HP code
+ that decides which registers to display (i.e. single precision
+ float, double precision float, general, special). Previously,
+ only handled TUI_GENERAL_REGS. Now that the code is hooked up,
+ compiling with -z poses a problem. When the first layout command
+ is 'layout regs', dataWin->detail is a NULL pointer, and gdb
+ core dumps.
+
+ * tuiLayout.c (_tuiSetLayoutTo): replace safe_free with free.
+
+ * tuiRegs.c #include "defs.h" earlier, to avoid problems in
+ <stdarg.h>. No idea exactly what's conflicting with what, but the
+ errors went away...
+ (_tuiRegisterFormat): Change so that function creates a GDB_FILE
+ object, calls pa_do_strcat_registers_info, copies the register
+ info into a buffer, and deallocates the GDB_FILE object. Remove
+ some code that is not executed. Also, call to
+ pa_do_strcat_registers_info has an additional parameter,
+ precision. This code requires some new per-target functions that
+ we don't want to merge. Dyke it out, with #ifdef
+ TUI_EXTENDED_FORMATTERS.
+ (_tuiSetSpecialRegsContent): this function was ifdefed out.
+ Hooked this up.
+ (_tuiSetGeneralAndSpecialRegsContent): this function was ifdefed
+ out. Hooked it up.
+ (IS_64BIT): Just define this to be zero; we're not merging in the
+ 64-bit support.
+ (tuiShowRegisters): Comment out all references to the "special"
+ regs; we don't have a distinction between the "special" and
+ "non-special" regs in most of our machine descriptions. This code
+ is PA-specific in other ways as well, and needs to be redesigned
+ to be portable to other processors.
+
+ * tuiWin.c: #include <string.h>, to get a declaration for
+ strchr.
+
+ * tui.c, tuiCommand.c, tuiData.c, tuiDataWin.c, tuiDisassem.c,
+ tuiGeneralWin.c, tuiIO.c, tuiLayout.c, tuiRegs.c, tuiSource.c,
+ tuiSourceWin.c, tuiStack.c, tuiWin.c: New files (from HP). Changed
+ bool to int throughout. Re-indented, GNU style.
+
+ * tui.h, tuiCommand.h, tuiData.h, tuiDataWin.h, tuiDisassem.h,
+ tuiGeneralWin.h, tuiIO.h, tuiLayout.h, tuiRegs.h, tuiSource.h,
+ tuiSourceWin.h, tuiStack.h, tuiWin.h: new files (from HP).
