b9b6dbc2ea Apply fix from zoo:
* munch:  Backslash escape vertical bar characters inside
	grep patterns since they have special meaning for some greps.

d1065385c1 * parse.c (write_exp_string): Complete rewrite to store string
contants as a leading explicit length, followed by the string data,
	followed by a trailing explicit length.
	* eval.c (evaluate_subexp), expprint.c (print_subexp),
	parse.c (length_of_subexp), parse.c (prefixify_subexp):
	Use recorded explicit length of strings in expression elements,
	rather than strlen.  Adjust code to skip over strings stored in
	expression elements, and code to access strings, to account for
	new leading explicit size expression element.
	* parse.c (length_of_subexp):  Test for minimum endpos of 1, not
	0, to avoid negative expression element indices.
	* valops.c (search_struct_method):  Minor whitespace change.

b0944a3377 * main.c (main): Print GDB version number in gdb -help; doc pid arg.

bac89d6ca8 * c-exp.y (yylex): Add tempbuf, tempbufindex, and tempbufsize,
which together maintain a dynamically expandable static buffer
	for the lexer to use when translating C strings to their internal
	form (other future uses possible).  Fix parsing of C style strings
	to do the normal C style input conversions of escaped character
	sequences.
	* valops.c (value_string):  Remove translation of escaped
	character sequences, now done in C expression parser.

cbf15d9a3d * infcmd.c (set_environment_command): Avoid skipping first
char of env value if an '=' appears in it.  Bug report and fix
	by Mark Jungerman, <maj@lucid.com>.

Thu Nov  5 23:04:38 1992 Rob Ryan (rr2b@andrew.cmu.edu)

        * xcoffexec.c (vmap_symtab): fixed a bug where if a object has no
        member, and the stat pointer passed to vmap_symtab was NULL, the
        wrong vmap entries would be modified.  Fixes behavior where
        attempting to load symbols for a module with no member would mess
        up already read in symbols.

* tm-rs6000.h (BELIEVE_PCC_PROMOTION): Define, since AIX cc gets
	it right.
	(aix_framedata): added nosavedpc field.
	(SAVED_PC_AFTER_CALL): Don't try to optimize; just call
	read_register.
	(FRAMELESS_FUNCTION_INVOCATION): Pass second argument of 0.
	(FRAME_SAVED_PC): If PC not saved, use SAVED_PC_AFTER_CALL.
	* rs6000-tdep.c (skip_prologue): Handle gcc generated stfd
	instructions as function_frame_info does.  Expand special case of
	st r31,-4(r1) to be st r31,NUM(r1), since gcc can generate offsets
	other than -4.
	(pop_frame): Add 4 rather than sizeof (int) to avoid host
	dependence.
	(function_frame_info): Set frameless if the function has no frame,
	and set nosavedpc if the PC was not saved.  Handle gcc generated
	stfd 31,-4(31); st 31, -12(31) correctly.
	(frameless_function_invocation): New second argument pcsaved; if 0
	return whether the function has a frame, if 1 return whether the
	function saved PC.
	(frame_initial_stack_address): Correct typo: cache registers for
	callee_fi, not for fi, (avoids reading garbage memory locations).

b6113cc408 * Makefile.in: Remove dependancies for 29k-share/dfe/yank.o and

udi_create_inferior, and udi_load to call common download()
routine.  Create download routine to load remote hosts directly
(with the help of BFD) so that we don't need yank.c and
mini2udi.c.
Fix udi_detach to call UDIDisconnect with
the right arguments.  Clean up udi_resume, don't assign tip_error
twice.  Clean up udi_wait, straighten out status codes.  Make
udi_kill really work.

pointed out by Jonathan Stone.

	* mips-tdep.c (init_extra_frame_info):  Undo John's last change.
	Always setup fci->frame, even if it's non-zero.  Too many places
	depend upon this behavior (and I have to get a release out the
	door)!
	* mipsread.c (parse_partial_symbols, psymtab_to_symtab_1):  Set
	processing_gcc_compilation if we find the embedded stabs marker.
	This fixes several bugs with finding the location of short or char
	function parameters passed on the stack.
