[GOLD] PowerPC function address in non-PIC
ppc32, like many targets, defines the address of a function as the PLT
call stub code for functions referenced but not defined in a non-PIC
executable. ppc32 gold, unlike other targets, inherits the ppc64
multiple stub capability for dealing with very large binaries where
one set of stubs can't be reached from all code locations. This means
there can be multiple choices of address for a function, which might
cause function pointer comparison failures. So for ppc32, make
non-branch references always use the first stub group.
(PowerPC64 ELFv1 is always PIC so doesn't need to define the address
of an external function as the PLT stub. PowerPC64 ELFv2 needs a
special set of global entry stubs to serve as the address of external
functions, so it too is not affected by this bug.)

stubs for ppc32 non-branch relocs in first stub table.

PowerPC64 stubs don't match calculated size
After the PR 21411 fix, the linker generated .eh_frame for ppc64 glink
can be edited by the generic code. The sequence of events goes
something like:
1) Some object file adds .eh_frame aligned to 8, making the output
.eh_frame aligned to at least 8, so linker generated .eh_frame FDE
is padded to an 8 byte boundary.
2) All .eh_frame past the glink .eh_frame is garbage collected.
3) Generic code detects that last FDE (the glink .eh_frame) doesn't

Add selftests run filtering
With the growing number of selftests, I think it would be useful to be
able to run only a subset of the tests. This patch associates a name to
each registered selftest. It then allows doing something like:
(gdb) maintenance selftest aarch64
Running self-tests.
Running selftest aarch64-analyze-prologue.
Running selftest aarch64-process-record.
Ran 2 unit tests, 0 failed
or with gdbserver:
./gdbserver --selftest=aarch64
In both cases, only the tests that contain "aarch64" in their name are
ran. To help validate that the tests you want to run were actually ran,
it also prints a message with the test name before running each test.
Right now, all the arch-dependent tests are registered as a single test
of the selftests. To be able to filter those too, I made them
"first-class citizen" selftests. The selftest type is an interface,
with different implementations for "simple selftests" and "arch
selftests". The run_tests function simply iterates on that an invokes
operator() on each test.
I changed the tests data structure from a vector to a map, because
- it allows iterating in a stable (alphabetical) order
- it allows to easily verify if a test with a given name has been
registered, to avoid duplicates

gdbserver: Remove gdb_id_to_thread_id
From what I understand, this function is not doing anything useful as of
today.
Here's the result of my archeological research:
- The field thread_info::gdb_id was added in
a06660f7 Use LWP IDs for thread IDs in gdbserver
There was problem when using a 32-bits gdb with a 64-bits gdbserver.
For some reason that I don't fully understand, the thread ids
exchanged between gdb and gdbserver could overflow a 32 bits data
type. My guess is that they were the thread address (e.g. the
0x7ffff7f20b40 in "Thread 0x7ffff7f20b40 (LWP 1058)" today). This
patch changed that so gdb/gdbserver would talk in terms of the OS
assigned numerical id (as shown in ps). It therefore added a way to
convert between this gdb_id (the numerical id) and the thread id (the
address).
-
95954743cb Implement the multiprocess extensions, and add linux
multiprocess supportNon-stop mode support.
This patch made gdbserver deal with threads using their numerical ids
and not the address-like id. Starting from there, the gdb_id <->
thread id conversion was not needed anymore, since the remote protocol
and gdbserver were using the same kind of ids again. The gdb_id field
in the thread_info structure was also unused starting there.
-
d50171e4 Teach linux gdbserver to step-over-breakpoints.
This patch moved the thread_info structure around, and got rid of the
gdb_id field (which was unused).
Looking at the implementation of gdb_id_to_thread_id, it is not doing
anything useful. It is looking up a thread by ptid using
find_thread_ptid, which basically loops over all threads looking at
their entry.id field. If a thread with that ptid is found, it returns
its entry.id field. So it will always return the same thing as it input
(with the exception of if no thread exist with that ptid, then it will
return null_ptid).

Make dwarf_expr_context::stack an std::vector
Replace the manually managed array with a vector. It is mostly
straightforward, except maybe one thing in execute_stack_op, in the
handling of DW_OP_fbreg. When the code stumbles on that opcode while
evaluating an expression, it needs to evaluate a subexpression to find
where the fb reg has been saved. Rather than creating a new context, it
reuses the current context. It saves the size of the stack before and
restores the stack to that size after.
I think we can do a little bit better by saving the current stack
locally and installing a new empty stack. This way, if the
subexpression is malformed and underflows, we'll get an exception.
Before, it would have overwritten the top elements of the top-level
expression. The evaluation of the top-level expression would have then
resumed with the same stack size, but possibly some corrupted elements.

This makes future const fixes simpler by reducing the number of lines

The last commit unfortunately was not enough to fix the build breakage
on AArch64. I made a mistake and did not test it alone on BuildBot,
but along with another patch that was responsible for fixing the
breakage.
The failure is:
In file included from /usr/include/string.h:640:0,

__warn_memset_zero_len ();
This is likely due to a GCC bug, because for some reason the compiler
assumes that the third argument to the memset:
memset (regcache->register_status, REG_UNAVAILABLE,
VEC_length (tdesc_reg_p, regcache->tdesc->reg_defs));
is always zero, which is not always true.
Anyway, the simple fix for this is to guard the memset calls with:
if (!VEC_empty (tdesc_reg_p, regcache->tdesc->reg_defs))
This time, I made sure to regtest only this patch on BuildBot, and it
finally solved the breakage.

gdb: Remove check for gdb_stderr == NULL
Recent changes made gdb_stderr a macro:
#define gdb_stderr (*current_ui_gdb_stderr_ptr ())
and current_ui_gdb_stderr_ptr return this:
¤t_ui->m_gdb_stderr
The problem is that this is undefined if current_ui is NULL, which can
happen early on during gdb start up.
If we run into an error during early gdb start up then we write the
error message to gdb_stderr. However, if we are too early during the
start up then current_ui is NULL, and using the gdb_stderr macro
triggers undefined behaviour.
We try to avoid this using a check 'gdb_stderr == NULL' which was fine
before the recent changes, but now, still triggers undefined behaviour.
A better check is instead 'current_ui == NULL' which is what I use in
this patch.
Triggering this failure is pretty hard, most of the really early errors
are only triggered if pretty basic things are not as expected, for
example, if the default signal handlers are not as expected. Seeing one
of these errors trigger usually means that someone working on gdb has
made an incorrect change. Still, the errors are present in gdb, and
should we ever trigger one it would be nice if gdb didn't crash.
For testing this change I've been applying this patch which adds an
unconditional error into a function called early during gdb start up.
Later in the same function is a real error call which, in some
circumstances could be triggered:

Remove make_cleanup_ui_out_table_begin_end
This changes the few remaining uses of
make_cleanup_ui_out_table_begin_end to use ui_out_emit_table instead,
and then removes the cleanup.
ChangeLog
2017-09-09 Tom Tromey <tom@tromey.com>
* ui-out.h (make_cleanup_ui_out_table_begin_end): Remove.
(class ui_out_emit_table): Update comment.

Use ui_out_emit_table and ui_out_emit_list in print_thread_info_1
This changes print_thread_info_1 to use ui_out_emit_table and
ui_out_emit_list. Which one is used depends on whether the ui-out is
mi-like; so the emitters are wrapped in gdb::optional.

Remove unnecessary function prototypes.
These prototypes were required when compiling GDB as C but are not
required for C++.

PowerPC64 --plt-align
This changes the PowerPC64 --plt-align option to perform the usual
alignment of code as suggested by its name, as well as the previous
behaviour of padding so as to reduce boundary crossing. The old
behaviour is had by using a negative parameter.
The default is also changed to align plt stub code by default to 32
byte boundaries, the point being to get better bctr branch prediction
on power8 and power9 hardware.

After _bfd_i386_elf_convert_load and _bfd_x86_64_elf_convert_load are
removed, elf_i386_convert_load_reloc and elf_x86_64_convert_load_reloc

__ehdr_start will be defined as a hidden symbol by linker at the later

Fix indentation for printing Fortran types with pointers
Printing the prefix "PTR TO -> (" resp. "REF TO ->(" ignored the active
indentation level. This caused inconsistent appearance of user-defined
Fortran types containing pointers. Fix by using "fprintfi_filtered" with the
current indentation level for outputting the prefix string. Add test case
ptr-indentation.
Example using 'ptype' on object of type:
type TypeWithPointer
integer i
integer, pointer:: p
end type TypeWithPointer
Before:
type = Type typewithpointer
integer(kind=4) :: i
PTR TO -> ( integer(kind=4) :: p)
End Type typewithpointer
After:
type = Type typewithpointer
integer(kind=4) :: i
PTR TO -> ( integer(kind=4) :: p)
