Enable displaced stepping over a BR/BLR instruction
Displaced stepping over an instruction executes a instruction in a
scratch area and then manually fixes up the PC address to leave
execution where it would have been if the instruction were in its
original location.
The BR instruction does not need modification in order to run correctly
at a different address, but the displaced step fixup method should not
manually adjust the PC since the BR instruction sets that value already.
The BLR instruction should also avoid such a fixup, but must also have
the link register modified to point to just after the original code
location rather than back to the scratch location.
This patch adds the above functionality.
We add this functionality by modifying aarch64_displaced_step_others
rather than by adding a new visitor method to aarch64_insn_visitor.
We choose this since it seems that visitor approach is designed
specifically for PC relative instructions (which must always be modified
when executed in a different location).
It seems that the BR and BLR instructions are more like the RET
instruction which is already handled specially in
aarch64_displaced_step_others.
This also means the gdbserver code to relocate an instruction when
creating a fast tracepoint does not need to be modified, since nothing
special is needed for the BR and BLR instructions there.
Regression tests showed nothing untoward on native aarch64 (though it
took a while for me to get the testcase to account for PIE).
------#####
Original observed (mis)behaviour before was that displaced stepping over
a BR or BLR instruction would not execute the function they called.
Most easily seen by putting a breakpoint with a condition on such an
instruction and a print statement in the functions they called.
When run with the breakpoint enabled the function is not called and
"numargs called" is not printed.
When run with the breakpoint disabled the function is called and the
message is printed.

With the new member functions for struct trad_frame_saved_reg, there is no
need to invoke some of the set/get functions anymore. This patch removes
those and adjusts all callers.
Even though the most natural initial state of a saved register value is
UNKNOWN, there are target backends relying on the previous initial state
of REALREG set to a register's own number. I noticed this in at least a
couple targets: aarch64 and riscv.
Because of that, I decided to keep the reset function that sets the set of
register values to REALREG. I can't exercise all the targets to make sure
the initial state change won't break things, hence why it is risky to change
the default.
Validated with --enable-targets=all on aarch64-linux Ubuntu 18.04/20.04.

This patch adds support for bfloat16 in AArch64 gdb.
Also adds the field "bf" to vector registers h0-h31.
Also adds the vector "bf" to h field in vector registers v0-v31.
The following is how the vector register h and v looks like.
Before this patch:
(gdb) p $h0
$1 = {f = 0, u = 0, s = 0}
(gdb) p/x $h0
$2 = {f = 0x0, u = 0x0, s = 0x0}
(gdb) p $v0.h
$3 = {f = {0, 0, 0, 0, 0, 0, 0, 0}, u = {0, 0, 0, 0, 0, 0, 0, 0}, s = {0, 0, 0, 0, 0, 0, 0, 0}}
(gdb) p/x $v0.h
$4 = {f = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, u = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0},
s = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}}
After this patch:
(gdb) p $h0
$1 = {bf = 0, f = 0, u = 0, s = 0}
(gdb) p/x $h0
$2 = {bf = 0x0, f = 0x0, u = 0x0, s = 0x0}
(gdb) p $v0.h
$3 = {bf = {0, 0, 0, 0, 0, 0, 0, 0}, f = {0, 0, 0, 0, 0, 0, 0, 0}, u = {0, 0, 0, 0, 0, 0, 0, 0},
s = {0, 0, 0, 0, 0, 0, 0, 0}}
(gdb) p/x $v0.h
$4 = {bf = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, f = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0},
u = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, s = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}}

The following patch drops the overloading going on with the trad_frame_saved_reg
struct and defines a new struct with a KIND enum and a union of different
fields.
The new struct looks like this:
struct trad_frame_saved_reg
{
setters/getters
...
private:
trad_frame_saved_reg_kind m_kind;
union {
LONGEST value;
int realreg;
LONGEST addr;
const gdb_byte *value_bytes;
} m_reg;
};
And the enums look like this:
/* Describes the kind of encoding a stored register has. */
enum class trad_frame_saved_reg_kind
{
/* Register value is unknown. */
UNKNOWN = 0,
/* Register value is a constant. */
VALUE,
/* Register value is in another register. */
REALREG,
/* Register value is at an address. */
ADDR,
/* Register value is a sequence of bytes. */
VALUE_BYTES
};
The patch also adds setters/getters and updates all the users of the old
struct.
It is worth mentioning that due to the previous overloaded nature of the
fields, some tdep files like to store negative offsets and indexes in the ADDR
field, so I kept the ADDR as LONGEST instead of CORE_ADDR. Those cases may
be better supported by a new enum entry.
I have not addressed those cases in this patch to prevent unwanted breakage,
given I have no way to test some of the targets. But it would be nice to
clean those up eventually.
The change to frame-unwind.* is to constify the parameter being passed to the
unwinding functions, given we now accept a "const gdb_byte *" for value bytes.
Tested on aarch64-linux/Ubuntu 20.04/18.04 and by building GDB with
--enable-targets=all.

Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c). I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it? What if the lines around it are also
wrong, do I fix them too? I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.
So I propose to fix as much as possible once and for all (hopefully).
One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines. My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for. So you
already need a somewhat efficient way to do this.
Using some interactive tool, rather than plain git-blame, makes this
trivial. For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too. My point is that it won't
really make archeology more difficult.
The other typical counter argument is that it will cause conflicts with
existing patches. That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve. I have also tried "git
rebase --ignore-whitespace", it seems to work well. Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

Move all debug prints of the "displaced" category to use a new
displaced_debug_printf macro, like what was done for infrun and others
earlier.
The debug output for one displaced step one amd64 looks like:
[displaced] displaced_step_prepare_throw: stepping process 3367044 now
[displaced] displaced_step_prepare_throw: saved 0x555555555042: 1e fa 31 ed 49 89 d1 5e 48 89 e2 48 83 e4 f0 50
[displaced] amd64_displaced_step_copy_insn: copy 0x555555555131->0x555555555042: b8 00 00 00 00 5d c3 0f 1f 84 00 00 00 00 00 f3
[displaced] displaced_step_prepare_throw: displaced pc to 0x555555555042
[displaced] resume_1: run 0x555555555042: b8 00 00 00
[displaced] displaced_step_restore: restored process 3367044 0x555555555042
[displaced] amd64_displaced_step_fixup: fixup (0x555555555131, 0x555555555042), insn = 0xb8 0x00 ...
[displaced] amd64_displaced_step_fixup: relocated %rip from 0x555555555047 to 0x555555555136
On test case needed to be updated because it relied on the specific
formatting of the message.
gdb/ChangeLog:
* infrun.h (displaced_debug_printf): New macro. Replace
displaced debug prints throughout to use it.
(displaced_debug_printf_1): New declaration.
(displaced_step_dump_bytes): Return string, remove ui_file
parameter, update all callers.
* infrun.c (displaced_debug_printf_1): New function.
(displaced_step_dump_bytes): Return string, remove ui_file
parameter
gdb/testsuite/ChangeLog:
* gdb.arch/amd64-disp-step-avx.exp: Update displaced step debug
expected output.

While working on something else, I noticed that tdesc_data_cleanup
took a void* parameter. Looking more into this, I found that
tdesc_use_registers expected a transfer of ownership.
I think it's better to express this sort of thing via the type system,
when possible. This patch changes tdesc_data_alloc to return a unique
pointer, changes tdesc_use_registers to accept an rvalue reference,
and then adapts all the users.
Note that a deleter structure is introduced to avoid having to move
tdesc_arch_data to the header file.

I initially noticed the problem with the addition of
gdb.dwarf2/dw2-line-number-zero.exp. The following failures showed up:
FAIL: gdb.dwarf2/dw2-line-number-zero.exp: continue to breakpoint: bar1
FAIL: gdb.dwarf2/dw2-line-number-zero.exp: bar1, 1st next
FAIL: gdb.dwarf2/dw2-line-number-zero.exp: bar1, 2nd next
FAIL: gdb.dwarf2/dw2-line-number-zero.exp: continue to breakpoint: bar2
FAIL: gdb.dwarf2/dw2-line-number-zero.exp: bar2, 1st next
FAIL: gdb.dwarf2/dw2-line-number-zero.exp: bar2, 2nd next
They happen because AArch64's prologue analyzer skips too many instructions
and ends up indicating a stopping point further into user code.

We should've stopped at 0x700, but the analyzer actually skips
that instruction and stops at 0x704. Then GDB ends up adjusting
the address further, and pushes the stopping point to 0x708 based on the
SAL information.
I'm not sure if this adjustment to 0x708 is correct though, as it ends up
skipping past a branch. But I'm leaving that aside for now.
One other complicating factor is that GCC seems to be hoisting up instructions
from user code, mixing them up with prologue instructions.
The following patch adjusts the heuristics a little bit, and tracks when the
SP and FP get used. If we notice an instruction that is not supposed to be
in the prologue, and this happens *after* SP/FP adjustments and saving of
registers, we stop the analysis.
This means, for PR26310, that we will now stop at 0x700.
I've also added a few more unit tests to make sure the updated behavior is
validated.

Replace all uses of it by type::field.
Note that since type::field returns a reference to the field, some spots
are used to assign the whole field structure. See ctfread.c, function
attach_fields_to_type, for example. This is the same as was happening
with the macro, so I don't think it's a problem, but if anybody sees a
really nicer way to do this, now could be a good time to implement it.

New in v3:
- Code cleanups based on reviews.
New in v2:
- Fixed misc problems based on reviews.
- Switched to using gdbarch_program_breakpoint_here_p as opposed to
gdbarch_insn_is_breakpoint.
- Fixed matching of brk instructions. Previously the mask was incorrect, which
was showing up as a few failures in the testsuite. Now it is clean.
- New testcase (separate patch).
- Moved program_breakpoint_here () to arch-utils.c and made it the default
implementation of gdbarch_program_breakpoint_here_p.

It was reported to me that program breakpoints (permanent ones inserted into
the code itself) other than the one GDB uses for AArch64 (0xd4200000) do not
generate visible stops when continuing, and GDB will continue spinning
infinitely.
This happens because GDB, upon hitting one of those program breakpoints, thinks
the SIGTRAP came from a delayed breakpoint hit...

Otherwise GDB will keep trying to resume the inferior and will keep
seeing the SIGTRAP's, without stopping.
To the user it appears GDB has gone into an infinite loop, interruptible only
by Ctrl-C.
Also, windbg seems to use a different variation of AArch64 breakpoint compared
to GDB. This causes problems when debugging Windows on ARM binaries, when
program breakpoints are being used.
The proposed patch creates a new gdbarch method (gdbarch_program_breakpoint_here_p)
that tells GDB whether the underlying instruction is a breakpoint instruction
or not.
This is more general than only checking for the instruction GDB uses as
breakpoint.
The existing logic is still preserved for targets that do not implement this
new gdbarch method.
The end result is like so:

In particular, this one:
FAIL: gdb.base/step-over-syscall.exp: fork: displaced=on: check_pc_after_cross_syscall: single step over fork final pc
When ptrace fork event reporting is enabled, GDB gets a PTRACE_EVENT_FORK
event whenever the inferior executes the fork syscall.
Then the logic is that GDB needs to step the inferior yet again in order to
receive a predetermined SIGTRAP, but no execution takes place because the
signal was already queued for delivery. That means the PC should stay the same.
I noticed the aarch64 code is currently adjusting the PC in this situation,
making the inferior skip an instruction without executing it.
The following change checks if we did not execute the instruction
(pc - to == 0), making proper adjustments for such case.
Regression tested on aarch64-linux-gnu on the tryserver.

I'd like to enable the -Wmissing-declarations warning. However, it
warns for every _initialize function, for example:
CXX dcache.o
/home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
/home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
_initialize_dcache (void)
^~~~~~~~~~~~~~~~~~
The only practical way forward I found is to add back the declarations,
which were removed by this commit:
commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9
Author: John Baldwin <jhb@FreeBSD.org>
Date: Sat Sep 9 11:02:37 2017 -0700
Remove unnecessary function prototypes.
I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

Add a new print_pc which prints both the PC and a new field addr_flags.
Call this wherever the PC is printed in stack.c.
Add a new gdbarch method get_pc_address_flags to obtain the addr_flag
contents. By default returns an empty string, on AArch64 this returns
PAC if the address has been masked in the frame.
Document this in the manual and NEWS file.
gdb/ChangeLog:
* NEWS (Other MI changes): New subsection.

When saving registers to the stack at the start of a function, not all state
needs to be saved. For example, only the first 64bits of float registers need
saving. However, a program may choose to store extra state if it wishes,
there is nothing preventing it doing so.
The aarch64_analyze_prologue will error if it detects extra state being
stored. Relex this restriction.
Tested via aarch64-prologue test.
gdb/ChangeLog:
* aarch64-tdep.c (aarch64_analyze_prologue): Allow any valid
register sizes.

* gdb.arch/aarch64-prologue.c: New test.

Armv8.3-a Pointer Authentication causes the function return address to be
obfuscated on entry to some functions. GDB must unmask the link register in
order to produce a backtrace.
The following patch adds markers of [PAC] to the bracktrace, to indicate
which addresses needed unmasking. This includes the backtrace when using MI.
For example, consider the following backtrace:
(gdb) bt
0 0x0000000000400490 in puts@plt ()
1 0x00000000004005dc in foo ("hello") at cbreak-lib.c:6
2 0x0000000000400604 [PAC] in bar () at cbreak-lib.c:12
3 0x0000000000400620 [PAC] in main2 () at cbreak.c:17
4 0x00000000004005b4 in main () at cbreak-3.c:10
The functions in cbreak-lib use pointer auth, which masks the return address
to the previous function, causing the addresses of bar (in the library) and main2
(in the main binary) to require unmasking in order to unwind the backtrace.
An extra bool is added alongside the prev_pc in the frame structure. At the
point at which the link register is unmasked, the AArch64 port calls into frame
to sets the bool. This is the most efficient way of doing it.
The marker is also added to the python frame printer, which is always printed if
set. The marker is not explicitly exposed to the python code.
I expect this will potentially cause issues with some tests in the testsuite
when Armv8.3 pointer authentication is used. This should be fixed up in the
the future once real hardware is available for full testsuite testing.
gdb/ChangeLog:
* NEWS: Expand the Pointer Authentication entry.
* aarch64-tdep.c (aarch64_frame_unmask_address): Rename from this.
(aarch64_frame_unmask_lr): ... to this.
(aarch64_prologue_prev_register, aarch64_dwarf2_prev_register):
Call aarch64_frame_unmask_lr.
* frame.c (struct frame_info): Add "masked" variable.
(frame_set_previous_pc_masked) (frame_get_pc_masked): New functions.
(fprint_frame): Check for masked pc.
* frame.h (frame_set_previous_pc_masked) (frame_get_pc_masked): New
declarations.
* python/py-framefilter.c (py_print_frame): Check for masked pc.
* stack.c (print_frame): Check for masked pc.
gdb/doc/ChangeLog:
* gdb.texinfo (AArch64 Pointer Authentication): New subsection.

I touched symtab.h and was surprised to see how many files were
rebuilt. I looked into it a bit, and found that defs.h includes
gdbarch.h, which in turn includes many things.
gdbarch.h is only needed by a minority ofthe files in gdb, so this
patch removes the include from defs.h and updates the fallout.
I did "wc -l" on the files in build/gdb/.deps; this patch reduces the
line count from 139935 to 137030; so there are definitely future
build-time savings here.
Note that while I configured with --enable-targets=all, it's possible
that some *-nat.c file needs an update. I could not test all of
these. The buildbot caught a few problems along these lines.

This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

Both the i386, X86_64 and AArch64 builds of gdbserver include a bunch of legacy
xml files, dat files and auto generated C files, when building for unit test.
These tests exists back from when feature target descriptions were added to
prove that the new target descriptions were identical to the original
older versions. The old files are not used for anything other than these tests.
Now that this has been proven, we are not gaining anything by keeping the
original files and tests. Should new functionality be added, it would break
the tests, unless the functionality was backported to the xml. There is no
requirement that we must match the exact xml from N releases ago. It adds
obfuscation, where as the feature target descriptions were meant to simplify
the code.
In addition, there are a bunch of xml and dat files which are completely unused.
This patch removes the selftests and the target descriptions from gdbserver.
Update the unittest to allow 0 tests (note, this failed on other targets that
never had any tests).
gdb/ChangeLog:
* aarch64-tdep.c: Remove xml self tests.
* amd64-linux-tdep.c: Likewise.

Running an address signed binary through GDB on a non pauth system
gives the following error:
Call Frame Instruction op 45 in vendor extension space is not handled on this architecture.
Instead GDB should ignore the op, treating it as a nop.
Add test case for pauth binaries, regardless of whether the target
supports it.
gdb/ChangeLog:
* aarch64-tdep.c (aarch64_execute_dwarf_cfa_vendor_op): Treat
DW_CFA_AARCH64_negate_ra_state as nop on non pauth targets.
gdb/testsuite/ChangeLog:
* gdb.arch/aarch64-pauth.c: New test.
* gdb.arch/aarch64-pauth.exp: New file.

While trying to build GDB on i686, I found the following error:
In file included from ../../gdb/common/common-defs.h:105,

This happens because aarch64-tdep.c:aarch64_gdbarch_init prints a
"uint64_t" variable using "%ld". This patch fixes the build by using
"pulongest" instead. As explained in a similar fix (commit
495143533ad95369811391c6e3c6dadd69d7dd67), this should be safe because
if aarch64-tdep.c is included in the build, then ULONGEST must be a
64-bit type.
gdb/ChangeLog:
2019-04-24 Sergio Durigan Junior <sergiodj@redhat.com>
* aarch64-tdep.c (aarch64_gdbarch_init): Use "pulongest" to print
"vq".

Replaces use of aarch64_type_align with common type_align function.
Doing this fixes a bug in aarch64_type_align where static fields are
considered as part of the alignment calculation of a struct, which
results in arguments passed on the stack being misaligned. This bug
is exposed in the new test gdb.cp/many-args.exp.
Part of the old aarch64_type_align is retained and used as the gdbarch
type align callback in order to correctly align vectors.
gdb/ChangeLog:
* aarch64-tdep.c (aarch64_type_align): Only handle vector override
case.
(pass_on_stack): Use type_align.
(aarch64_gdbarch_init): Register aarch64_type_align gdbarch
function.
gdb/testsuite/ChangeLog:
* gdb.cp/many-args.cc: New file.
* gdb.cp/many-args.exp: New file.

Override the thread_architecture method, similar to SPU. If the vector
length has changed, then find the arch using info, making sure the vector
length is passed down to the init routine.
In the init routine, ensure the arch has the correct vector length.
Example output. Program is stopped in thread 2, just before it calls prctl
to change the vector length
