Simon Marchi 6e1e1966ba Pass inferior down to target_detach and to_detach
The to_detach target_ops method implementations are currently expected
to work on current_inferior/inferior_ptid.  In order to make things more
explicit, and remove some "shadow" parameter passing through globals,
this patch adds an "inferior" parameter to to_detach.  Implementations
will be expected to use this instead of relying on the global.  However,
to keep things simple, this patch only does the minimum that is
necessary to add the parameter.  The following patch gives an example of
how one such implementation would be adapted.  If the approach is deemed
good, we can then look into adapting more implementations.  Until then,
they'll continue to work as they do currently.

Simon Marchi 6bd6f3b656 Remove args from target detach
I was looking into adding a parameter to target_detach, and was
wondering what the args parameter was.  It seems like in the distant
past, it was possible to specify a signal number when detaching.  That
signal was injected in the process before it was detached.  There is an
example of code handling this in linux_nat_detach.  With today's GDB, I
can't get this to work.  Doing "detach 15" (15 == SIGTERM) doesn't work,
because detach is a prefix command and doesn't recognize the sub-command
15.  Doing "detach inferiors 15" doesn't work because it expects a list
of inferior id to detach.  Therefore, I don't think there's a way of
invoking detach_command with a non-NULL args.  I also didn't find any
documentation related to this feature.

I assume that this feature stopped working when detach was made a prefix
command, which is in f73adfeb8b (sorry,
there's no commit title) from 2006.  Given that this feature was broken
for such a long time and we haven't heard anything (AFAIK, I did not
find any related bug), I think it's safe to remove it, as well as the
args parameter to target_detach.  If someone wants to re-introduce it, I
would suggest rethinking the user interface, and in particular would
suggest using signal name instead of numbers.

I tried to fix all the impacted code, but I might have forgotten some
spots.  It shouldn't be hard to fix if that's the case.  I also couldn't
build-test everything I changed, especially the nto and solaris stuff.

Pedro Alves 8d297bbf60 Type-safe wrapper for enum flags
This patch fixes C++ build errors like this:

/home/pedro/gdb/mygit/cxx-convertion/src/gdb/linux-tdep.c:1126:35: error: invalid conversion from ‘int’ to ‘filterflags’ [-fpermissive]
       | COREFILTER_HUGETLB_PRIVATE);
                                   ^

This is a case of enums used as bit flags.  Unlike "regular" enums,
these values are supposed to be or'ed together.  However, in C++, the
type of "(ENUM1 | ENUM2)" is int, and you then can't assign an int to
an enum variable without a cast.  That means that this:

  enum foo_flags flags = 0;

  if (...)
    flags |= FOO_FLAG1;
  if (...)
    flags |= FOO_FLAG2;

... would have to be written as:

  enum foo_flags flags = (enum foo_flags) 0;

  if (...)
    flags = (enum foo_flags) (flags | FOO_FLAG1);
  if (...)
    flags = (enum foo_flags) (flags | FOO_FLAG2);

which is ... ugly.  Alternatively, we'd have to use an int for the
variable's type, which isn't ideal either.

This patch instead adds an "enum flags" class.  "enum flags" are
exactly the enums where the values are bits that are meant to be ORed
together.

This allows writing code like the below, while with raw enums this
would fail to compile without casts to enum type at the assignments to
'f':

  enum some_flag
  {
     flag_val1 = 1 << 1,
     flag_val2 = 1 << 2,
     flag_val3 = 1 << 3,
     flag_val4 = 1 << 4,
  };
  DEF_ENUM_FLAGS_TYPE(enum some_flag, some_flags)

  some_flags f = flag_val1 | flag_val2;
  f |= flag_val3;

It's also possible to assign literal zero to an enum flags variable
(meaning, no flags), dispensing either adding an awkward explicit "no
value" value to the enumeration or the cast to assignments from 0.
For example:

  some_flags f = 0;
  f |= flag_val3 | flag_val4;

Note that literal integers other than zero do fail to compile:

  some_flags f = 1; // error

C is still supported -- DEF_ENUM_FLAGS_TYPE is just a typedef in that
case.

Pedro Alves 9e8915c6ce record-full/record-btrace: software/hardware breakpoint trap
This adjusts the record targets to tell the core whether a trap was
caused by a breakpoint.  Targets that can do this should report
breakpoint traps with the PC already adjusted, so this removes the
re-incrementing record-full was doing.

These targets need to be adjusted before process_stratum targets
beneath are, otherwise target_supports_stopped_by_sw_breakpoint,
etc. would fall through to the target beneath while
recording/replaying, and the core would get confused.

Tested on x86-64 Fedora 20, native and gdbserver.

Pedro Alves 8213266aea Fix "is a record target open" checks.
RECORD_IS_USED and record_full_open look at current_target.to_stratum
to determine whether a record target is in use.  This is wrong because
arch_stratum is greater than record_stratum, so if an arch_stratum
target is pushed, RECORD_IS_USED and record_full_open will miss it.

To fix this, we can use the existing find_record_target instead, which
looks up for a record stratum target across the target stack.  Since
that means exporting find_record_target in record.h, RECORD_IS_USED
ends up redundant, so the patch eliminates it.

That exercise then reveals other issues:

- adjust_pc_after_break is gating record_full_... calls based on
RECORD_IS_USED.  But, record_full_ calls shouldn't be made when
recording with the record-btrace target.  So this adds a new
record_full_is_used predicate to be used in that spot.

- record_full_open says "Process record target already running", even
if the recording target is record-btrace ("process record" is the
original complete name of the record-full target).  record_btrace_open
only says "The process is already being recorded." and does not
suggest "record stop", like record-full does.  The patch factors out
and merges that error to a new record_preopen function that all record
targets call in their open routine.

Tested on x86_64 Fedora 17.

Joel Brobecker ecd75fc8ee Update Copyright year range in all files maintained by GDB. 2014-01-01 07:54:24 +04:00
Tom Tromey 52554a0e32 constify to_detach
This patch constifies the target_ops method to_detach.

This is a small cleanup, but also, I think, a bug-prevention fix,
since gdb already acts as if the "args" argument here was const.

In particular, top.c:quit_force calls kill_or_detach via
iterate_over_inferiors.  kill_or_detach calls target_detach, passing
the same argument each time.  So, if one of these methods was not
const-correct, then kill_or_detach would change its behavior in a
strange way.

I could not build every target I modified in this patch.  I've
inspected them all by hand, though.  Many targets do not use the
"args" parameter; a couple pass it to atoi; and a few pass it on to
the to_detach method of the target beneath.  The only code that
required a real change was in linux-nat.c, and that only needed the
introduction of a temporary variable for const-correctness.
