I think this patch is wrong. Starting with that commit (f30d5c7),
some tests (e.g. mi-break.exp) started to fail for me, because
of gdb segfaulting.

The address of expr is passed to the cleanup. When the cleanup is ran,
expr is no longer in scope, so what is at that address is probably not
safe to use anymore. That's my guess.

Relax PR 15228 protected visibility restriction

Allows .dynbss copy of shared library protected visibility variables
if they are read-only.

To recap: Copying a variable from a shared library into an executable's
.dynbss is an old hack invented for non-PIC executables, to avoid the
text relocations you'd otherwise need to access a shared library
variable.  This works with ELF shared libraries because global
symbols can be overridden.  The trouble is that protected visibility
symbols can't be overridden.  A shared library will continue to access
it's own protected visibility variable while the executable accesses a
copy.  If either the shared library or the executable updates the
value then the copy diverges from the original.  This is wrong since
there is only one definition of the variable in the application.

So I made the linker report an error on attempting to copy protected
visibility variables into .dynbss.  However, you'll notice the above
paragraph contains an "If".  An application that does not modify the
variable value remains correct even though two copies of the variable
exist.  The linker can detect this situation if the variable was
defined in a read-only section.

On Windows amd64, setting a breakpoint on a symbol imported from a

two locations, one on the import stub, and another in the shared
library, while on i386, the breakpoint is only set in the shared

This is due to the minimal symbol for the import stub not being
correctly given the type mst_solib_trampoline on Windows amd64, unlike
Windows i386.

As currently written, coff_symfile_read is always skipping over the
character after the "__imp_" (amd64) or "_imp_" (i386) prefix,
assuming that it is '_'.  However, while i386 is an underscored
target, amd64 is not.

(gdb) break a/break-asm-file0.s:func
Breakpoint 1 at 0x40053f: file a/break-asm-file0.s, line 7.

As we can see, breakpoint is set at the start address of function func
on x86, which means no prologue is skipped.  On other targets, such as
arm and aarch64, breakpoint is set at the address *after* the start
address, which is mapped to line 8.  Then test fails.

In fact, it is lucky this test doesn't fail on x86 and x86_64, whose
gdbarch method skip_prologue doesn't reply on skip_prologue_using_sal
if producer isn't clang.

  if (find_pc_partial_function (start_pc, NULL, &func_addr, NULL))
    {
      CORE_ADDR post_prologue_pc
= skip_prologue_using_sal (gdbarch, func_addr);
      struct compunit_symtab *cust = find_pc_compunit_symtab (func_addr);

      /* Clang always emits a line note before the prologue and another
 one after.  We trust clang to emit usable line notes.  */
      if (post_prologue_pc
  && (cust != NULL
      && COMPUNIT_PRODUCER (cust) != NULL
      && startswith (COMPUNIT_PRODUCER (cust), "clang ")))
        return max (start_pc, post_prologue_pc);
    }

so it doesn't return and go further to prologue analyser.  Since ".int 0"
isn't an instruction of prologue, nothing is skipped, starting address
is used, and test passes.

however, on targets which don't have such producer checking, the first
line number entry is skipped, and skip_prologue_using_sal returns sal
represents the second line number entry.

The idea of this patch is to force GDB stop at somewhere which is stilled
mapped to line 7 after skipping prologue.  I choose to add a new line
number entry for the following instruction but mapped to the same line (7),
because I see the comments in dwarf2read.c,

   ... fact that two consecutive
   line number entries for the same line is a heuristic used by gcc
   to denote the end of the prologue.

then the line table becomes:

Associate target_ops with target_fileio file descriptors

Various target_fileio_* functions use integer file descriptors to

the target stack as they are used, which causes problems if the
target stack changes after the file is opened.

For example, if a file is opened on a remote target and the remote
target disconnects or closes the remote target will be popped off
the stack.  If target_fileio_close is then called on that file and
"set auto-connect-native-target" is "on" (the default) then the
native target's close method will be called.  If the file opened
on the remote happens to share the same number with a file open in
GDB then that file will be closed by mistake.

Remove 'step' parameters from 'proceed' and 'resume'

The "step" parameters of 'proceed' and 'resume' aren't really useful
as indication of whether run control wants to single-step the target,
as that information must already be retrievable from
currently_stepping.  In fact, if currently_stepping disagrees with
whether we single-stepped the target, then things break.  Thus instead
of having the same information in two places, this patch removes those
parameters.

Setting 'step_start_function' is the only user of proceed's 'step'
argument, other than passing the 'step' argument down to 'resume' and
debug log output.  Move that instead to set_step_frame, where we
already set other related fields.

9 years agoMake "set scheduler-locking step" depend on user intention, only
Pedro Alves [Tue, 24 Mar 2015 17:50:31 +0000 (17:50 +0000)]
Make "set scheduler-locking step" depend on user intention, only

Currently, "set scheduler-locking step" is a bit odd.  The manual
documents it as being optimized for stepping, so that focus of
debugging does not change unexpectedly, but then it says that
sometimes other threads may run, and thus focus may indeed change
unexpectedly...  A user can then be excused to get confused and wonder
why does GDB behave like this.

I don't think a user should have to know about details of how "next"
or whatever other run control command is implemented internally to
understand when does the "scheduler-locking step" setting take effect.

This patch completes a transition that the code has been moving
towards for a while.  It makes "set scheduler-locking step" hold
threads depending on whether the _command_ the user entered was a
stepping command [step/stepi/next/nexti], or not.

Before, GDB could end up locking threads even on "continue" if for
some reason run control decides a thread needs to be single stepped
(e.g., for a software watchpoint).

After, if a "continue" happens to need to single-step for some reason,
we won't lock threads (unless when stepping over a breakpoint,
naturally).  And if a stepping command wants to continue a thread for
bit, like when skipping a function to a step-resume breakpoint, we'll
still lock threads, so focus of debugging doesn't change.

In order to make this work, we need to record in the thread structure
whether what set it running was a stepping command.

(A follow up patch will remove the "step" parameters of 'proceed' and 'resume')

FWIW, Fedora GDB, which defaults to "scheduler-locking step" (mainline
defaults to "off") carries a different patch that goes in this
direction as well.

sim: frv: delete UART device support

This looks like copy & paste logic from the m32r port (and history
suggests this as well).  Since building with hw & device support
enabled leads to failures:
sim/frv/devices.c: In function 'device_io_read_buffer':
sim/frv/devices.c:39:15: error: 'UART_INCHAR_ADDR' undeclared (first use in this function)

Delete it entirely.  We leave device support in place as it is used
to flush the scache.
