Yao Qi 8aa08a8dd5 Relax pattern to match the output of "info frame" in gdb.base/savedregs.exp
Hi,
I see the following two fails in gdb.base/savedregs.exp on aarch64-linux,

info frame 2^M
Stack frame at 0x7ffffffa60:^M
 pc = 0x40085c in thrower (/home/yao/SourceCode/gnu/gdb/git/gdb/testsuite/gdb.base/savedregs.c:49); saved pc = 0x400898^M
 called by frame at 0x7ffffffa70, caller of frame at 0x7fffffe800^M
 source language c.^M
 Arglist at 0x7ffffffa60, args: ^M
 Locals at 0x7ffffffa60, Previous frame's sp is 0x7ffffffa60^M
(gdb) FAIL: gdb.base/savedregs.exp: Get thrower info frame

info frame 2^M
Stack frame at 0x7fffffe800:^M
 pc = 0x400840 in catcher (/home/yao/SourceCode/gnu/gdb/git/gdb/testsuite/gdb.base/savedregs.c:42); saved pc = 0x7fb7ffc350^M
 called by frame at 0x7fffffe800, caller of frame at 0x7fffffe7e0^M
 source language c.^M
 Arglist at 0x7fffffe7f0, args: sig=11^M
 Locals at 0x7fffffe7f0, Previous frame's sp is 0x7fffffe800
(gdb) FAIL: gdb.base/savedregs.exp: Get catcher info frame

looks the test expects to match "Saved registers:" from the output of
"info frame", but no registers are saved on these two frames, because
thrower and catcher are simple and leaf functions.

(gdb) disassemble thrower
Dump of assembler code for function thrower:
   0x0000000000400858 <+0>:	mov	x0, #0x0                   	// #0
   0x000000000040085c <+4>:	strb	wzr, [x0]
   0x0000000000400860 <+8>:	ret
End of assembler dump.
(gdb) disassemble catcher
Dump of assembler code for function catcher:
   0x0000000000400838 <+0>:	sub	sp, sp, #0x10
   0x000000000040083c <+4>:	str	w0, [sp,#12]
   0x0000000000400840 <+8>:	adrp	x0, 0x410000
   0x0000000000400844 <+12>:	add	x0, x0, #0xb9c
   0x0000000000400848 <+16>:	mov	w1, #0x1                   	// #1
   0x000000000040084c <+20>:	str	w1, [x0]
   0x0000000000400850 <+24>:	add	sp, sp, #0x10
   0x0000000000400854 <+28>:	ret

There are two ways to fix these fails, one is to modify functions to
force some registers saved (for example, doing function call in them),
and the other one is to relax the pattern to optionally match
"Saved registers:".  I did both, and feel that the latter is simple,
so here is it.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
