Sergio Durigan Junior fafcc06ab2 Sanitize input_interrupt output
Hi,

This patch is a follow-up of the following discussions:

  <https://sourceware.org/ml/gdb-patches/2014-12/msg00421.html>
  <https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01293.html>

input_interrupt is currently emiting non-printable characters, which
is confusing the dg-extract-results.sh script.  This is obviously not
a good thing, and, by following Pedro's advices here:

  <https://gcc.gnu.org/ml/gcc-patches/2014-12/msg01320.html>

I adapted the function to print "client connection closed" when it
receives a NUL character, or use the "isprint" function to decide how
to print the received char.  I tested it by running the testcases that
were printing the non-printable chars before:

  gdb.base/gdb-sigterm.exp
  gdb.threads/non-ldr-exc-1.exp
  gdb.threads/non-ldr-exc-2.exp
  gdb.threads/non-ldr-exc-3.exp
  gdb.threads/non-ldr-exc-4.exp
  gdb.threads/thread-execl.exp

and confirming that they print the right message.  I tried a bit to
come up with a testcase for this, but failed, and since I did not want
to spend too much time on it, I'm sending the patch anyway.

Comments are welcome, as usual.

	* remote-utils.c: Include ctype.h.
	(input_interrupt): Explicitly handle the case when the char
	received is the NUL byte.  Improve the printing of non-ASCII
	characters.

Yao Qi 9d85a0ec6b Clean up gdb.trace/entry-values.exp
This patch is to clean up gdb.trace/entry-values.exp as a preparation
of the next patch.  It updates the comments to reflect the code.

One DIE generated in dwarf assembler is

 		GNU_call_site {
		    {low_pc "$bar_start + $bar_call_foo" addr}
 		    {abstract_origin :$foo_label}

the DW_AT_low_pc attribute is the return address after the call, so I
rename variable bar_call_foo to returned_from_foo.
