For each MAJOR-MINOR opcode tuple, we can have either a 3-operand, or
2-operand, or a single operand instruction format, depending on the
values present in i-field, and a-field.
The disassembler is reading the section containing the extension
instruction format and stores them in a table. Each table element
represents a linked list with encodings for a particular MAJOR-MINOR
tuple.
The current implementation checks only against the first element of
the list, hence, the issue.
This patch is walking the linked list until empty or finds an opcode
match. It also adds a test outlining the found problem.

There were always various problems with compatibility with ccache:
https://bugzilla.redhat.com/show_bug.cgi?id=488863https://bugzilla.redhat.com/show_bug.cgi?id=759592https://sourceware.org/ml/gdb-patches/2009-02/msg00397.html
IMO in a summary ccache finds more a benefit of faster compilation despite the
debug info is no longer exactly the same (as without ccache).
Although for example in this case ccache helped to find a real GDB bug:
https://sourceware.org/ml/gdb-patches/2015-01/msg00497.html
For the GDB testcases ccache has (IMO) no real performance advantage and it
just brings heisenbugs - false FAILs - from time to time:
Breakpoint 1, main () at gdb/testsuite/gdb.base/vdso-warning.c:21^M
21 return 0;^M
(gdb) PASS: gdb.base/vdso-warning.exp: run: startup
->
Breakpoint 1, main () at gdb/testsuite/gdb.base/hbreak-unmapped.c:21^M
21 return 0;^M
(gdb) FAIL: gdb.base/vdso-warning.exp: run: startup
So I find most safe and easy to just disable ccache for all testsuites.

Before SPARC V9 the effect of having a delayed branch instruction in the
delay slot of a conditional delayed branch was undefined.
In SPARC V9 DCTI couples are well defined.
However, starting with the UltraSPARC Architecture 2005, DCTI
couples (of all kind) are deprecated and should not be used, as they may
be slow or behave differently to what the programmer expects.
This patch adds a new command line option --dcti-couples-detect to `as',

The last commit was supposed to have the reference to ptrace () removed.

* server.c (start_inferior): Fixed comment, requested comment change
didn't get updated correctly. Removed reference to ptrace () call as
it is only true on Linux systems.
The test checks to make sure GDB exits cleanly if there is
no valid target binary. Currently, ppc and S390 fail on this
test. The function target_post_create_inferior () calls
linux_post_create_inferior () which calls the architecture
specific functions s390_arch_setup () and ppc_arch_setup ()
which make ptrace calls to access the architecture specific
registers. These ptrace calls fail because the process does
not exist causing GDB to exit on error.
This patch checks to see if the initial ptrace (PTRACE_TRACEME, ...)
call returned a status of TARGET_WAITKIND_EXITED indicating the
target has already exited. If the target has exited, then the
target_post_create_inferior () is not called since there is no
inferior to be setup. The test to see if the initial ptrace
call succeeded is done after the ptrace (PTRACE_TRACEME, ...)
call and the wait for the inferior process to stop, assuming
it exists, has occurred.
The patch has been tested on X86 64-bit, ppc64 and s390. If
fixes the test failures on ppc64 and s390. The test does not
fail on X86 64-bit. The patch does not introduce any additional
regression failures on any of these three platforms.

This patch adds alternate CPU names which adhere to the number of the
architecture document. So instead of having z196, zEC12, and z13 you

The alternate names are supposed to improve compatibility with the IBM

GCC 6's ICF optimization pass is making the declaration of 'm1' and
'm2', on gdb.base/stap-probe.c, to be unified. However, this leads to
only one instance of the probe 'two' being created, which causes a
failure on the testsuite (which expects a multi-location breakpoint to
be inserted on the probe).
This patch fixes this failure by declaring a dummy variable on 'm1',
and using it as an argument to m1's version of probe 'two'. Since we
do not care about the contents of the functions nor about the
arguments of each probe 'two', this is OK.

On various GNU Elf architectures, including AArch64, ARM, s390/s390x,
ppc32/64, and sparc32/64, the dynamic loader passes HWCAP as a parameter
to each ifunc resolver. Currently there is an open glibc Bugzilla that
requests this to be generalized to all architectures:
https://sourceware.org/bugzilla/show_bug.cgi?id=19766
And various ifunc resolvers already rely on receiving HWCAP. Currently
GDB always calls an ifunc resolver without any arguments; thus the
resolver may receive garbage, and based on that, the resolver may decide
to return a function that is not suited for the given platform.
This patch always passes HWCAP to ifunc resolvers, even on systems where
the dynamic loader currently behaves otherwise. The rationale is
that (1) the dynamic loader may get adjusted on those systems as well in
the future; (2) passing an unused argument should not cause a problem
with existing resolvers; and (3) the logic is much simpler without such
a distinction.

I noticed that if input is already pending on the new-ui TTY, gdb
internal-errors.
E.g., create /dev/pts/2, and type anything there (even just <return>
is sufficient).
Now start GDB creating a new UI on that TTY, while at the same time,
running a synchronous execution command. Something like:
$ gdb program -ex "new-ui console /dev/pts/2" -ex "start"
Back on /dev/pts/2, we get:
(gdb) .../src/gdb/event-top.c:360: internal-error: double prompt
A problem internal to GDB has been detected,
further debugging may prove unreliable.
While the main UI was waiting for "start" to finish, gdb kepts pumping
events, including the input fd of the extra console. The problem is
that stdin_event_handler doesn't restore the current UI back to what
it was, assuming that it's only ever called from the top level event
loop. However, in this case, it's being called from the nested event
loop from within maybe_wait_sync_command_done.
When finally the "start" command is done, we reach the code that
prints the prompt in the main UI, just before starting the main event
loop. Since now the current UI is pointing at the extra console (by
mistake), we find ourselves printing a double prompt on the extra
console. This is caught by the assertion that fails, as shown above.
Since other event handlers also don't restore the UI (e.g., signal
event handlers), I think it's better if whatever is pumping events to
take care to restore the UI, if it cares. That's what this patch
does. New test included.
