Patrick Palka a88d0bb33c Update our idea of our terminal's dimensions even outside of TUI
When in the CLI, GDB's "width" and "height" variables are not kept in sync
when the underlying terminal gets resized.

This patch fixes this issue by making sure sure to update GDB's "width"
and "height" variables in the !tui_active case of our SIGWINCH handler.

gdb/ChangeLog:

	* tui/tui-win.c (tui_sigwinch_handler): Remove now-stale comment.

Alan Modra faa2211d4d Tidy PowerPC gold find_global_entry uses
Completely removing the assert probably wasn't the best idea, so
reinstate it for allocated sections.  Also cope with debug info

And a tidy.  find_global_entry now returns an Address, so make temps
holding the return value of type Address, and compare against
invalid_address.

Alan Modra 6ec65f28db PowerPC gold assertion on missing global entry stub
Global entry stubs are used on ELFv2 to provide addresses for
functions not defined in a non-PIC executable but whose address is
taken, in much the same way as PLT stub code is used on other
targets to provide function addresses.  We don't want to insert a
global entry stub just because (bogus) debug info refers to the
address of a non-local function, but we also don't want gold to die.

	on missing global entry stub due to bogus debug info.

Patrick Palka 2eb639cbe4 TUI: avoid calling strcpy() on identical string objects
In tui_set_source_content(), when offset == 0 the source and destination

overlap.

Patrick Palka 9720679936 Fix PR gdb/18155
For no good reason the function tui_free_window() is freeing the locator
window when we pass it an SRC_WIN or a DISASSEM_WIN.  This behavior
doesn't make much sense because the locator window is always visible and
its contents do not change when the main window changes.

This behavior triggers the above PR because when we switch from one TUI
window to another (in the PR, from the src window to the asm window) we
call tui_free_window() on the previously active window (in the PR, the
src window).  The function then frees the src window along with the
locator window and later we segfault when the now-active asm window
tries to query the locator window about the inferior's PC.

This patch fixes this apparently wrong behavior by changing
tui_free_window() to not free the locator window when we pass it an
SRC_WIN or a DISASSEM_WIN.

	PR gdb/18155

Patrick Palka 63ed81829e Make type-safe the 'content' field of struct tui_gen_win_info
The 'content' field of struct tui_gen_win_info currently has type
void ** but the field always stores an object of type tui_win_content.
Instead of unnecessarily casting to and from void ** we should just give
the field the type tui_win_content in the first place.

involving the 'content' struct field that I could find.

John Baldwin d2b41ca0f9 Add support for catching exec events on FreeBSD.
FreeBSD kernels that support fork tracing always stop a process to
report events for exec.  Such a process will have the PL_FLAG_EXEC
flag set in the pl_flags field of the ptrace_lwpinfo struct returned
by PT_LWPINFO.  The structure does not include the pathname passed to
exec, so use fbsd_pid_to_exec_file to query the pathname of the
process' executable.

gdb/ChangeLog:

	* fbsd-nat.c: (fbsd_wait) [PL_FLAG_EXEC]: Report TARGET_WAITKIND_EXECD
	event if PL_FLAG_EXEC is set.

John Baldwin e58e05d677 Enable fork tracing for native FreeBSD targets.
Enable PT_FOLLOW_FORK on all processes.  When this is enabled, both
the parent and child process stop when a fork or vfork occurs.

A target operation for wait uses PT_LWPINFO to fetch more detailed
information about the state of a stopped process.  A parent process
sets the PL_FLAG_FORKED flag in the pl_flags field of the structure
returned by PT_LWPINFO as well as the pid of the new child process.
The child process sets the PL_FLAG_CHILD flag in the pl_flags field.

When a fork is detected, the wait hook waits for both processes to
report their respective events.  It then reports the fork to GDB as
a single TARGET_WAITKIND_FORKED or TARGET_WAITKIND_VFORKED event.
The kernel does not guarantee the order the events are reported in.
If the parent process' event is reported first, then the wait hook
explicitly waits for the child process.  If the child process' event
is reported first, the event is recorded on an internal list of
pending child events and the wait hook waits for another event.
Later when the parent process' event is reported, the parent will
use the previously-recorded child process event instead of explicitly
waiting on the child process.

To distinguish vfork events from fork events, the external process
structure for the child process is extracted from the kernel.  The
P_PPWAIT flag is set in the ki_flags field of this structure if the
process was created via vfork, but it is not set for a regular fork.

Pierre-Marie de Rodat 9e19566105 [Ada] Cache all static structures and reset cache during resolution
Currently, ada-lang.c:template_to_static_fixed_type (working on
structure types only) caches its result into the unused TYPE_TARGET_TYPE
field. This introduces inconsistencies when the input type is
specialized, for instance during type resolution: the cached static
fixed type is copied along with the original type, but it's no longer
adapted to the copy once the copy is modified:
template_to_static_fixed_type has to compute another static fixed type
for it.

This change first introduces a cache reset during type resolution for
structure types so that this inconsistency does not happen anymore. It
also makes template_to_static_fixed_type smarter with respect to types
that do not need static fixed copies so that less computations is done
in general.

This inconsistency was spotted thanks to code reading, not because of
any sort of failure and we did not manage to exhibit a failure yet, so
no testcase for this.

gdb/ChangeLog:

	* ada-lang.c (template_to_static_fixed_type): Return input type
	when it is already fixed. Cache the input type itself when not
	creating a static fixed copy. Make it explicit that we never
	molestate the input type.
	* gdbtypes.c (resolve_dynamic_struct): Reset the
	TYPE_TARGET_TYPE field for resolved copies.

Joel Brobecker 460efde16c [Ada] Preserve typedef layer when getting struct element
Consider the following declarations:

   type Int_Access is access Integer;
   type Record_Type is record
      IA : Int_Access;
   end record;

   R : Record_Type;

Printing the type name of "R.IA" yields:

    (gdb) whatis r.ia
    type = access integer

It should be:

    (gdb) whatis r.ia
    type = bar.int_access

Looking at the debugging info, field "r.ia" is defined as
a typedef which has the name of the field type:

        .uleb128 0x3    # (DIE (0x4e) DW_TAG_typedef)
        .long   .LASF4  # DW_AT_name: "bar__int_access"
        .long   0x8b    # DW_AT_type

... with the typedef's target type being an anonymous pointer
type:

        .uleb128 0x7    # (DIE (0x8b) DW_TAG_pointer_type)
        .byte   0x8     # DW_AT_byte_size
        .long   0x91    # DW_AT_type

What happens here is that a couple of function in ada-lang.c
always start by stripping all typedef layers when handling
struct fields, with the effect of making us lose the type name
in this case.

We did not understand this at the time the code was written,
but typedefs should be stripped only when we know we do not
need them. So this patch, adjust the code to avoid the stripping
while handling the fields, and adds it back in the lone place
which handles the result of processing and didn't know how to
handle typedefs struct fields yet.

        * ada-lang.c (ada_is_tagged_type): Add call to ada_check_typedef.

Andreas Krebbel 963a4320b4 S/390: Fix gotreloc_31-1 testcase.
Since we changed the default arch for objdump to zarch the following
testcase needs to check for the real instruction mnemonics instead of
just bytes.

This fixes the following testsuite fail on s390x:

FAIL: GOT: symbol address load from got to larl

Sergio Durigan Junior 2d369d8e97 Clear variable "coredump_var_addr" before using it on gdb.base/coredump-filter.exp
This commit is a continuation of the fix committed on:

  commit 8cd8f2f8ac
  Author: Sergio Durigan Junior <sergiodj@redhat.com>
  Date:   Mon Apr 13 02:40:08 2015 -0400

      Rename variable "addr" to "coredump_var_addr" in gdb.base/coredump-filter.exp

Pedro pointed out that this fix was not complete, because the
testsuite could be run several times in a row (for example), which
means that it is not enough to just make the variable name unique: it
also needs to be cleared out if it is global.

This commit does that.  It is actually just a commit made to make
things totally correct; this specific test does not fail if you run it
several times in a row.

Alan Modra 44bd1acd55 Non-alloc sections don't belong in PT_LOAD segments
Taking them out showed a bug in the powerpc64 backend with .branch_lt
being removed from output_bfd but not from previously set up segment
section maps.  Removing the bfd sections meant their sh_flags (and
practically everything else) remaining zero, ie. not SHF_ALLOC,
triggering complaints about "`.branch_lt' can't be allocated in
segment".
