Fix PR gdb/15294: list with unlimited listsize broken
Currently, "set listsize -1" is supposed to mean "unlimited" source
lines, but, alas, it doesn't actually work:
(gdb) set listsize -1
(gdb) show listsize
Number of source lines gdb will list by default is unlimited.
(gdb) list 1
(gdb) list 1
(gdb) list 1
(gdb) set listsize 10

Before this patch:
http://sourceware.org/ml/gdb-patches/2012-08/msg00367.html
was applied, the "set listsize" command was a var_integer command, and
"unlimited" was set with 0. Internally, var_integer maps 0 to INT_MAX
case var_integer:
{
...
if (val == 0 && c->var_type == var_integer)
val = INT_MAX;
The change in that patch to zuinteger_unlimited command, meant that -1
is left as -1 in the command's control variable (lines_to_list), and
the code in source.c isn't expecting that -- it only expects positive
numbers.
I previously suggested fixing the code and keeping the new behavior,
but I found that "set listsize 0" is currently used in the wild, and
we do have a bunch of other commands where "0" means unlimited, so I'm
thinking that changing this command alone in isolation is not a good
idea.
So I now strongly prefer reverting back the behavior in 7.6 to the
same behavior the command has had since 2006 (0==unlimited, -1=error).
Before that, set listsize -1 would be accepted as unlimited as well.
After 7.6 is out, in mainline, we can get back to reconsidering
changing this command's behavior, if there's a real need for being
able to suppress output. For now, let's play it safe.
The "list line 1 with unlimited listsize" test in list.exp was
originally written years and years ago expecting 0 to mean "no
output", but GDB never actually worked that way, even when the tests
were written, so the tests had been xfailed then. This patch now
adjusts the test to the new behavior, so that the test actually
passes, and the xfail is removed.

you'd get:

Forbid "set history size (INT_MAX..UINT_MAX)"
The whole readline interface is signed, and works with the 0..INT_MAX
range.
We don't allow setting the size to UINT_MAX directly. The documented
user visible interface is "use 0 for unlimited". The UINT_MAX
representation is an implementation detail we could change, e.g., by
keeping a separate flag for "unlimited", which is actually what the
readline interface does (stifled vs non stifled). Generically
speaking, exposing this detail to clients of the interface may make
our lives complicated when we find the need to extend the range of
some command in the future, and it's better if users
(frontends/scripts) aren't relying on anything but what we tell them
to use for "unlimited". Making values other than 0 error out is the
way to prevent users from using those ranges inappropriately. Quite
related, note:
(gdb) set history size 0xffffffff
integer
4294967295 out of range
But,
(gdb) set history size 0xfffffffe
(gdb) show history size
The size of the command history is unlimited.
(gdb) set history size 0x100000000
integer
4294967296 out of range
If values over INT_MAX are accepted as unlimited, then there's no good
argument for only accepting [INT_MAX..UINT_MAX) as valid "unlimited"
magic numbers, while not accepting [UINT_MAX..inf).
Making the setting's control variable of different type (unsigned int)
of the rest of the related code (int) adds the need to recall that one
variable among all these is unsigned, and that one need to think about
whether these comparisons are signed or unsigned, along with the
promotion/conversion rules. Since this is an easy to forget detail,
this patch renames the variable to at least make it more obvious that
this variable is not one of GNU history's public int variables, which
are all signed. We don't actually need the only code that presently
is affected by this, though, the code that is computing the current
history's length. We can just use GNU history's history_length
instead:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Variable: int history_length
The number of entries currently stored in the history list.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/* Return the history entry which is logically at OFFSET in the history array.
OFFSET is relative to history_base. */
HIST_ENTRY *
history_get (offset)
int offset;
{
int local_index;
local_index = offset - history_base;
return (local_index >= history_length || local_index < 0 || the_history == 0)
? (HIST_ENTRY *)NULL
: the_history[local_index];
}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
At the time this code was added (gdb 4.13 ~1994), 'history_length' was
extern, but not documented in readline's GNU history documents, so I
guess it wasn't considered public then and the loop was the
workaround.
One of the warts of GDB choosing 0 to mean unlimited is that "set
history size 0" behaves differently from 'HISTSIZE=0 gdb'. The latter
leaves GDB with no history, while the former means "unlimited"...
$ HISTSIZE=0 ./gdb
...
(gdb) show history size
The size of the command history is 0.
We shouldn't really change what HISTSIZE=0 means, as bash, etc. also
handle 0 as real zero, and zero it's what really makes sense.

Get rid of "No such file or directory" in the testsuite's btrace support detection.
When I tried running the btrace tests, I noticed something odd in the gdb.log file:
(gdb) run
Starting program: /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.btrace/btrace22343.x
Breakpoint 1, main () at /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.btrace/btrace22343.c:1

^^^^^^^^^^^^^^^^^^^^^^^^^
(gdb) record btrace
Target does not support branch tracing.
(gdb) testcase ../../../src/gdb/testsuite/gdb.btrace/enable.exp completed in 0 seconds
I knew that the btrace tests on my machine weren't supposed to work,
but still, that error made me wonder if the test had something broken,
and waste a few minutes looking up where that is coming from.
The issue is that the btrace detection deletes the source file right
after compiling it, and before GDB has a chance to open it. It's
really harmless, but I'd rather spare others from going through the
same exercise.
We now get the regular:

sim: rewrite SIM_AC_OPTION_HARDWARE a bit to simplify things
There's no need to put the majority of the logic into the 3rd arg of the
AC_ARG_ENABLE. Coupled with the lack of indentation, it makes it hard to
follow, error prone to update, and duplicates code (with the 4th arg).
So pull the logic out of the 3rd arg and outside of the AC_ARG_ENABLE
macro. This allows us to gut the 4th arg entirely, merge with the code
that followed the macro, and fix bugs related to the new dv-sockser in
the process.
Hopefully building the various sims with the default sim-hardware
settings, as well as with explicit --{dis,en}able-sim-hardware flags,
should all just work now.

Linux: No need to set ptrace event options in fork/clone children.
Oleg Nesterov told me that the Linux kernel copies the parent's ptrace
options to fork/clone children, so there's no need for GDB to do that
manually.
I was actually a bit surprised, since I thought the ptracer had to
always set the ptrace options itself, and GDB is indeed calling
PTRACE_SETOPTIONS for each new fork child, if it'll stay attached.
Looking at the history of that code, I found that is was actually I
who added that set-ptrace-options-in-children bit, back in
http://sourceware.org/ml/gdb-patches/2009-05/msg00656.html. But,
honestly, I don't recall why I needed that. I think I may have just
blindly believed it was necessary.
I then looked back at the history of all the PTRACE_SETOPTIONS code we
have, and found that gdb never did copy the ptrace options before my
patch. But, when gdbserver learnt to use PTRACE_EVENT_CLONE, at
http://sourceware.org/ml/gdb-patches/2007-10/msg00547.html, it was
made to do 'ptrace (PTRACE_SETOPTIONS, new_pid, 0,
PTRACE_O_TRACECLONE)' for all new clones. Hmmm. But, GDB itself
never did that, so it can't really ever have been necessary, I
believe, otherwise GDB should have been doing it too.
(GDBserver doesn't support following forks, and so naturally doesn't
do any PTRACE_SETOPTIONS on fork children.)
So this patch removes the -I believe- unnecessary ptrace syscalls.
Tested on x86_64 Fedora 17, native/gdbserver, and on x86_64 RHEL5
native/gdbserver (Linux 2.6.18, I think a ptrace-on-utrace kernel).
No regressions.

Casting to gdb_byte would fix it, however, writing an
unsigned int array like this
static unsigned int hppa64_tramp[] = {
0xeac0f000, /* bve,l (r22),%r2 */
0x0fdf12d1, /* std r31,-8(,sp) */
0x0fd110c2, /* ldd -8(,sp),rp */
0xe840d002, /* bve,n (rp) */
0x08000240 /* nop */
...
directly to target memory assumes the host endianness is the same as
the target's. hppa is big endian, so I believe this patch should be
correct -- it defines the array as a gdb_byte array. It uses a macro
to make the insn bytes a little more readable. I thought of using
write_memory_unsigned_integer once for each element of the unsigned
int array, but this way keeps issuing a single target memory write /
roundtrip for the whole trampoline.
