auto-generate most target debug methods
The target debug methods are inconsistently maintained. Most to_*
methods have some kind of targetdebug awareness, but not all of them
do. The ones that do vary in the quantity and quality of output they
generate.
This patch changes most of the target debug methods to be
automatically generated. All the arguments are printed, and separate
lines are printed for entering and existing the outermost call to the
target stack.
For example now you'd see:
-> multi-thread->to_terminal_ours (...)
-> multi-thread->to_is_async_p (...)
<- multi-thread->to_is_async_p (0x1ebb580) = 1
<- multi-thread->to_terminal_ours (0x1ebb580)
-> multi-thread->to_thread_address_space (...)
<- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1
In this case you can see nested calls. The "multi-thread" on the left
hand side is the topmost target's shortname.
There are some oddities with this patch. I'm on the fence about it
all, I really just wrote it on a whim.
It's not simple to convert every possible method, since a few don't
participate in target delegation.
Printing is done by type, so I introduced some new
debug-printing-specific typedefs to handle cases where it is nicer to
do something else.
On the plus side, this lays the groundwork for making targetdebug
affect every layer of the target stack. The idea would be to wrap
each target_ops in the stack with its own debug_target, and then you
could see calls propagate down the stack and back up; I suppose with
indentation to make it prettier. (That said there are some gotchas
lurking in this idea due to target stack introspection.)

/* Printers for the debug target. Each prints an object of a given

type to a string that needn't be freed. Most printers are macros,

for brevity, but a few are static functions where more complicated
|
|
|
|
|
|
behavior is needed.
|

|
|
|
|
|

References to these printers are automatically generated by

make-target-delegates. See the generated file target-delegates.c.

In a couple cases, a special printing function is defined and then

used via the TARGET_DEBUG_PRINTER macro. See target.h.
|

|
|

A few methods still have some explicit targetdebug code in
|
|
|
|
|
|
target.c. In most cases this is because target delegation hasn't
|
|
|
|
|
|
been done for the method; but individual cases vary. For instance,
|
|
|
|
|
|
target_store_registers does some special register printing that is
|
|
|
|
|

more simply done there, and target_xfer_partial additionally

bypasses the debug target. */

auto-generate most target debug methods
The target debug methods are inconsistently maintained. Most to_*
methods have some kind of targetdebug awareness, but not all of them
do. The ones that do vary in the quantity and quality of output they
generate.
This patch changes most of the target debug methods to be
automatically generated. All the arguments are printed, and separate
lines are printed for entering and existing the outermost call to the
target stack.
For example now you'd see:
-> multi-thread->to_terminal_ours (...)
-> multi-thread->to_is_async_p (...)
<- multi-thread->to_is_async_p (0x1ebb580) = 1
<- multi-thread->to_terminal_ours (0x1ebb580)
-> multi-thread->to_thread_address_space (...)
<- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1
In this case you can see nested calls. The "multi-thread" on the left
hand side is the topmost target's shortname.
There are some oddities with this patch. I'm on the fence about it
all, I really just wrote it on a whim.
It's not simple to convert every possible method, since a few don't
participate in target delegation.
Printing is done by type, so I introduced some new
debug-printing-specific typedefs to handle cases where it is nicer to
do something else.
On the plus side, this lays the groundwork for making targetdebug
affect every layer of the target stack. The idea would be to wrap
each target_ops in the stack with its own debug_target, and then you
could see calls propagate down the stack and back up; I suppose with
indentation to make it prettier. (That said there are some gotchas
lurking in this idea due to target stack introspection.)

Get rid of VEC (mem_region)
This patch removes VEC (mem_region). Doing so requires touching a lot
of little things here and there.
The fields in mem_attrib are now initialized during construction. The
values match those that were in default_mem_attrib (now removed).
unknown_mem_attrib is also removed, and replaced with a static method
(mem_attrib::unknown) that returns the equivalent.
mem_region is initialized in a way similar to mem_region_init (now
removed) did.
I found the organization of mem_region_list and target_mem_region_list a
bit confusing. Sometimes mem_region_list points to the same vector as
target_mem_region_list (and therefore does not own it), and sometimes
(when the user manually edits the mem regions) points to another vector,
and in this case owns it. To avoid this ambiguity, I think it is
simpler to have two vectors, one for target-defined regions and one for
user-defined regions, and have mem_region_list point to one or the
other. There are now no vector objects dynamically allocated, both are
static.
The make-target-delegates script does not generate valid code when a
target method returns a type with a parameter list. For this reason, I
created a typedef (mem_region_vector) that's only used in the target_ops
structure. If you speak perl, you are welcome to improve the script!
Regtested on the buildbot.

Extended-remote follow-exec
This patch implements support for exec events on extended-remote Linux
targets. Follow-exec-mode and rerun behave as expected. Catchpoints and
test updates are implemented in subsequent patches.
This patch was derived from a patch posted last October:
https://sourceware.org/ml/gdb-patches/2014-10/msg00877.html.
It was originally based on some work done by Luis Machado in 2013.
IMPLEMENTATION
----------------
Exec events are enabled via ptrace options.
When an exec event is detected by gdbserver, the existing process
data, along with all its associated lwp and thread data, is deleted
and replaced by data for a new single-threaded process. The new
process data is initialized with the appropriate parts of the state
of the execing process. This approach takes care of several potential
pitfalls, including:
* deleting the data for an execing non-leader thread before any
wait/sigsuspend occurs
* correctly initializing the architecture of the execed process
We then report the exec event using a new RSP stop reason, "exec".
When GDB receives an "exec" event, it saves the status in the event
structure's target_waitstatus field, like what is done for remote fork
events. Because the original and execed programs may have different
architectures, we skip parsing the section of the stop reply packet
that contains register data. The register data will be retrieved
later after the inferior's architecture has been set up by
infrun.c:follow_exec.
At that point the exec event is handled by the existing event handling
in GDB. However, a few changes were necessary so that
infrun.c:follow_exec could accommodate the remote target.
* Where follow-exec-mode "new" is handled, we now call
add_inferior_with_spaces instead of add_inferior with separate calls
to set up the program and address spaces. The motivation for this
is that add_inferior_with_spaces also sets up the initial architecture
for the inferior, which is needed later by target_find_description
when it calls target_gdbarch.
* We call a new target function, target_follow_exec. This function
allows us to store the execd_pathname in the inferior, instead of
using the static string remote_exec_file from remote.c. The static
string didn't work for follow-exec-mode "new", since once you switched
to the execed program, the original remote exec-file was lost. The
execd_pathname is now stored in the inferior's program space as a
REGISTRY field. All of the requisite mechanisms for this are
defined in remote.c.

Introduce gdb_disassembly_flags
For some reason I ended up staring at some of the "int flags" in
btrace-related code, and I got confused because I had no clue what the
flags where supposed to indicate.
Fix that by using enum_flags, so that:
#1 - it's clear from the type what the flags are about, and
#2 - the compiler can catch mismatching mistakes

Convert struct target_ops to C++
I.e., use C++ virtual methods and inheritance instead of tables of
function pointers.
Unfortunately, there's no way to do a smooth transition. ALL native
targets in the tree must be converted at the same time. I've tested
all I could with cross compilers and with help from GCC compile farm,
but naturally I haven't been able to test many of the ports. Still, I
made a best effort to port everything over, and while I expect some
build problems due to typos and such, which should be trivial to fix,
I don't expect any design problems.
* Implementation notes:
- The flattened current_target is gone. References to current_target
or current_target.beneath are replaced with references to
target_stack (the top of the stack) directly.
- To keep "set debug target" working, this adds a new debug_stratum
layer that sits on top of the stack, prints the debug, and delegates
to the target beneath.
In addition, this makes the shortname and longname properties of
target_ops be virtual methods instead of data fields, and makes the
debug target defer those to the target beneath. This is so that
debug code sprinkled around that does "if (debugtarget) ..." can
transparently print the name of the target beneath.
A patch later in the series actually splits out the
shortname/longname methods to a separate structure, but I preferred
to keep that chance separate as it is associated with changing a bit
the design of how targets are registered and open.
- Since you can't check whether a C++ virtual method is overridden,
the old method of checking whether a target_ops implements a method
by comparing the function pointer must be replaced with something
else.
Some cases are fixed by adding a parallel "can_do_foo" target_ops
methods. E.g.,:
+ for (t = target_stack; t != NULL; t = t->beneath)
{
- if (t->to_create_inferior != NULL)
+ if (t->can_create_inferior ())
break;
}
Others are fixed by changing void return type to bool or int return
type, and have the default implementation return false or -1, to
indicate lack of support.
- make-target-delegates was adjusted to generate C++ classes and
methods.
It needed tweaks to grok "virtual" in front of the target method
name, and for the fact that methods are no longer function pointers.
(In particular, the current code parsing the return type was simple
because it could simply parse up until the '(' in '(*to_foo)'.
It now generates a couple C++ classes that inherit target_ops:
dummy_target and debug_target.
Since we need to generate the class declarations as well, i.e., we
need to emit methods twice, we now generate the code in two passes.
- The core_target global is renamed to avoid conflict with the
"core_target" class.
- ctf/tfile targets
init_tracefile_ops is replaced by a base class that is inherited by
both ctf and tfile.
- bsd-uthread
The bsd_uthread_ops_hack hack is gone. It's not needed because
nothing was extending a target created by bsd_uthread_target.
- remote/extended-remote targets
This is a first pass, just enough to C++ify target_ops.
A later pass will convert more free functions to methods, and make
remote_state be truly per remote instance, allowing multiple
simultaneous instances of remote targets.
- inf-child/"native" is converted to an actual base class
(inf_child_target), that is inherited by all native targets.
- GNU/Linux
The old weird double-target linux_ops mechanism in linux-nat.c, is
gone, replaced by adding a few virtual methods to linux-nat.h's
target_ops, called low_XXX, that the concrete linux-nat
implementations override. Sort of like gdbserver's
linux_target_ops, but simpler, for requiring only one
target_ops-like hierarchy, which spares implementing the same method
twice when we need to forward the method to a low implementation.
The low target simply reimplements the target_ops method directly in
that case.
There are a few remaining linux-nat.c hooks that would be better
converted to low_ methods like above too. E.g.:
linux_nat_set_new_thread (t, x86_linux_new_thread);
linux_nat_set_new_fork (t, x86_linux_new_fork);
linux_nat_set_forget_process
That'll be done in a follow up patch.
- We can no longer use functions like x86_use_watchpoints to install
custom methods on an arbitrary base target.
The patch replaces instances of such a pattern with template mixins.
For example memory_breakpoint_target defined in target.h, or
x86_nat_target in x86-nat.h.
- linux_trad_target, MIPS and Alpha GNU/Linux
The code in the new linux-nat-trad.h/c files which was split off of
inf-ptrace.h/c recently, is converted to a C++ base class, and used
by the MIPS and Alpha GNU/Linux ports.
- BSD targets
The
$architecture x NetBSD/OpenBSD/FreeBSD
support matrix complicates things a bit. There's common BSD target
code, and there's common architecture-specific code shared between
the different BSDs. Currently, all that is stiched together to form
a final target, via the i386bsd_target, x86bsd_target,
fbsd_nat_add_target functions etc.
This introduces new fbsd_nat_target, obsd_nat_target and
nbsd_nat_target classes that serve as base/prototype target for the
corresponding BSD variant.
And introduces generic i386/AMD64 BSD targets, to be used as
template mixin to build a final target. Similarly, a generic SPARC
target is added, used by both BSD and Linux ports.
- bsd_kvm_add_target, BSD libkvm target
I considered making bsd_kvm_supply_pcb a virtual method, and then
have each port inherit bsd_kvm_target and override that method, but
that was resulting in lots of unjustified churn, so I left the
function pointer mechanism alone.

Change pid_to_str to return std::string
Currently the target pid_to_str method returns a const char *, so many
implementations have a static buffer that they update. This patch
changes these methods to return a std::string instead. I think this
is cleaner and avoids possible gotchas when calling pid_to_str on
different ptids in a single statement. (Though no such calls exist
currently.)
This also updates various helper functions, and the gdbarch pid_to_str
methods.
I also made a best effort to fix all the callers, but I can't build
some of the *-nat.c files.
Tested by the buildbot.

auto-generate most target debug methods
The target debug methods are inconsistently maintained. Most to_*
methods have some kind of targetdebug awareness, but not all of them
do. The ones that do vary in the quantity and quality of output they
generate.
This patch changes most of the target debug methods to be
automatically generated. All the arguments are printed, and separate
lines are printed for entering and existing the outermost call to the
target stack.
For example now you'd see:
-> multi-thread->to_terminal_ours (...)
-> multi-thread->to_is_async_p (...)
<- multi-thread->to_is_async_p (0x1ebb580) = 1
<- multi-thread->to_terminal_ours (0x1ebb580)
-> multi-thread->to_thread_address_space (...)
<- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1
In this case you can see nested calls. The "multi-thread" on the left
hand side is the topmost target's shortname.
There are some oddities with this patch. I'm on the fence about it
all, I really just wrote it on a whim.
It's not simple to convert every possible method, since a few don't
participate in target delegation.
Printing is done by type, so I introduced some new
debug-printing-specific typedefs to handle cases where it is nicer to
do something else.
On the plus side, this lays the groundwork for making targetdebug
affect every layer of the target stack. The idea would be to wrap
each target_ops in the stack with its own debug_target, and then you
could see calls propagate down the stack and back up; I suppose with
indentation to make it prettier. (That said there are some gotchas
lurking in this idea due to target stack introspection.)

Make target_wait options use enum flags
This changes TARGET_WNOHANG to be a member of an enum, rather than a
define, and also adds a DEF_ENUM_FLAGS_TYPE for this type. Then, it
changes target_wait and the various target wait methods to use this
type rather than "int".
This didn't catch any bugs, but it seems like a decent cleanup
nevertheless.
I did not change deprecated_target_wait_hook, since that's only used
out-of-tree (by Insight), and there didn't seem to be a need.
I can't build some of these targets, so I modified them on a
best-effort basis. I don't think this patch should go in before the
release branch is made.

auto-generate most target debug methods
The target debug methods are inconsistently maintained. Most to_*
methods have some kind of targetdebug awareness, but not all of them
do. The ones that do vary in the quantity and quality of output they
generate.
This patch changes most of the target debug methods to be
automatically generated. All the arguments are printed, and separate
lines are printed for entering and existing the outermost call to the
target stack.
For example now you'd see:
-> multi-thread->to_terminal_ours (...)
-> multi-thread->to_is_async_p (...)
<- multi-thread->to_is_async_p (0x1ebb580) = 1
<- multi-thread->to_terminal_ours (0x1ebb580)
-> multi-thread->to_thread_address_space (...)
<- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1
In this case you can see nested calls. The "multi-thread" on the left
hand side is the topmost target's shortname.
There are some oddities with this patch. I'm on the fence about it
all, I really just wrote it on a whim.
It's not simple to convert every possible method, since a few don't
participate in target delegation.
Printing is done by type, so I introduced some new
debug-printing-specific typedefs to handle cases where it is nicer to
do something else.
On the plus side, this lays the groundwork for making targetdebug
affect every layer of the target stack. The idea would be to wrap
each target_ops in the stack with its own debug_target, and then you
could see calls propagate down the stack and back up; I suppose with
indentation to make it prettier. (That said there are some gotchas
lurking in this idea due to target stack introspection.)
Regtested on x86-64 Fedora 20.

target_pass_signals/target_program_signals: Use gdb::array_view
This replaces the pointer and length parameters of target_pass_signals
and target_program_signals with a gdb::array_view parameter, and fixes
the fallout.
In infrun.c, the signal_stop, signal_print, signal_program,
signal_catch, signal_pass globals are currently pointers to
heap-allocated memory. I see no point in that, so I converted them to
arrays. This allows simplifying the calls to
target_pass_signals/target_program_signals, since we can pass the
array directly, which can implicitly convert to gdb::array_view.
gdb/ChangeLog:
2019-01-24 Pedro Alves <palves@redhat.com>
* infrun.c (signal_stop, signal_print, signal_program)
(signal_catch, signal_pass): Now arrays instead of pointers.

(signal_catch_update, handle_command, _initialize_infrun): Adjust.
