... using automake 1.11.1, which is the version we're currently
using throughout, instead of 1.11.3. This should be a no-op in
practice, but will help automake/aclocal version-related
differences to cloud real changes being made.
sim/common/ChangeLog:
* aclocal.m4, configure: Regenerate using automake 1.11.1.
Using e.g.
.arch_extension simd
.arch_extension nocrypto
so far results in SIMD support getting disabled, which I can't see being
the purpose of the "no"-prefixed variants of architecture extension
specifications.
Of course it is questionable whether the current, counter intuitive
behavior needs to be retained, and the new behavior perhaps be made work
through e.g. a newly recognized "no-" prefix.

This fixes a similar error as in the Python support code where
trying to create an empty array.
In guile/scm-type.c::tyscm_array_1, the funtion raises an exception

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.
gdb/gdbserver/ChangeLog:
2014-12-29 Sergio Durigan Junior <sergiodj@redhat.com>
* 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.

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.
gdb/testsuite:
2014-12-29 Yao Qi <yao@codesourcery.com>
* gdb.trace/entry-values.exp: Update comments. Rename variable
bar_call_foo to returned_from_foo.
