Remove get_thread_id
This patch removes get_thread_id from aarch64-linux-nat.c,
arm-linux-nat.c and xtensa-linux-nat.c.
get_thread_id was added in this commit below in 2000,
41c49b06c471443d3baf2eaa2463a315f9b5edca
https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html
which predates the ptid_t stuff added into GDB. Nowadays, lwpid of
inferior_ptid is only zero when the inferior is created (in
fork-child.c:fork_inferior) and its lwpid will be set after
linux_nat_wait_1 gets the first event. After that, lwpid of
inferior_ptid is not zero for linux-nat target, then we can use
ptid_get_lwp, so this function isn't needed anymore.
Even when GDB attaches to a process, the lwp of inferior_ptid
isn't zero, see linux-nat.c:linux_nat_attach,
/* The ptrace base target adds the main thread with (pid,0,0)
format. Decorate it with lwp info. */
ptid = ptid_build (ptid_get_pid (inferior_ptid),
ptid_get_pid (inferior_ptid),
0);
Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid
temperately for calling linux_ops->to_xfer_partial, but all the
affected functions in this patch are not called in
linux_ops->to_xfer_partial.
I think we can safely remove get_thread_id for all linux native targets.
Regression tested on arm-linux and aarch64-linux. Unable to build
native GDB and test it on xtensa-linux.

/* Read the floating point state. */

Convert have_ptrace_getregset to a tri-state boolean
have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have
some conditions like "if (have_ptrace_getregset)", which is not correct.
I'll explain why it is not correct in the following example. This fix
to this problem to replace the test (have_ptrace_getregset) to test
(have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc.
However Doug thinks it hinders readability
https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide
to add a new enum tribool and change have_ptrace_getregset to it, in
order to make these tests more readable.
have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in
$ARCH_linux_read_description according to the capability of the kernel.
However, it is possible that have_ptrace_getregset is used before it is
set to 0 or 1, which means it is still -1. This is shown below.

PTRACE_GETREGSET command is used even GDB doesn't know whether

However it doesn't work on arm-linux if the kernel doesn't support
PTRACE_GETREGSET at all. We'll get:

Remove get_thread_id
This patch removes get_thread_id from aarch64-linux-nat.c,
arm-linux-nat.c and xtensa-linux-nat.c.
get_thread_id was added in this commit below in 2000,
41c49b06c471443d3baf2eaa2463a315f9b5edca
https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html
which predates the ptid_t stuff added into GDB. Nowadays, lwpid of
inferior_ptid is only zero when the inferior is created (in
fork-child.c:fork_inferior) and its lwpid will be set after
linux_nat_wait_1 gets the first event. After that, lwpid of
inferior_ptid is not zero for linux-nat target, then we can use
ptid_get_lwp, so this function isn't needed anymore.
Even when GDB attaches to a process, the lwp of inferior_ptid
isn't zero, see linux-nat.c:linux_nat_attach,
/* The ptrace base target adds the main thread with (pid,0,0)
format. Decorate it with lwp info. */
ptid = ptid_build (ptid_get_pid (inferior_ptid),
ptid_get_pid (inferior_ptid),
0);
Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid
temperately for calling linux_ops->to_xfer_partial, but all the
affected functions in this patch are not called in
linux_ops->to_xfer_partial.
I think we can safely remove get_thread_id for all linux native targets.
Regression tested on arm-linux and aarch64-linux. Unable to build

/* Read the floating point state. */

Convert have_ptrace_getregset to a tri-state boolean
have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have
some conditions like "if (have_ptrace_getregset)", which is not correct.
I'll explain why it is not correct in the following example. This fix
to this problem to replace the test (have_ptrace_getregset) to test
(have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc.
However Doug thinks it hinders readability
https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide
to add a new enum tribool and change have_ptrace_getregset to it, in
order to make these tests more readable.
have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in
$ARCH_linux_read_description according to the capability of the kernel.
However, it is possible that have_ptrace_getregset is used before it is
set to 0 or 1, which means it is still -1. This is shown below.

PTRACE_GETREGSET command is used even GDB doesn't know whether
PTRACE_GETREGSET is supported or not. It is wrong, but works on x86.
However it doesn't work on arm-linux if the kernel doesn't support
PTRACE_GETREGSET at all. We'll get:

Convert have_ptrace_getregset to a tri-state boolean
have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have
some conditions like "if (have_ptrace_getregset)", which is not correct.
I'll explain why it is not correct in the following example. This fix
to this problem to replace the test (have_ptrace_getregset) to test
(have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc.
However Doug thinks it hinders readability
https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide
to add a new enum tribool and change have_ptrace_getregset to it, in
order to make these tests more readable.
have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in
$ARCH_linux_read_description according to the capability of the kernel.
However, it is possible that have_ptrace_getregset is used before it is
set to 0 or 1, which means it is still -1. This is shown below.

Remove get_thread_id
This patch removes get_thread_id from aarch64-linux-nat.c,
arm-linux-nat.c and xtensa-linux-nat.c.
get_thread_id was added in this commit below in 2000,
41c49b06c471443d3baf2eaa2463a315f9b5edca
https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html
which predates the ptid_t stuff added into GDB. Nowadays, lwpid of
inferior_ptid is only zero when the inferior is created (in
fork-child.c:fork_inferior) and its lwpid will be set after
linux_nat_wait_1 gets the first event. After that, lwpid of
inferior_ptid is not zero for linux-nat target, then we can use
ptid_get_lwp, so this function isn't needed anymore.
Even when GDB attaches to a process, the lwp of inferior_ptid
isn't zero, see linux-nat.c:linux_nat_attach,
/* The ptrace base target adds the main thread with (pid,0,0)
format. Decorate it with lwp info. */
ptid = ptid_build (ptid_get_pid (inferior_ptid),
ptid_get_pid (inferior_ptid),
0);
Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid
temperately for calling linux_ops->to_xfer_partial, but all the
affected functions in this patch are not called in
linux_ops->to_xfer_partial.
I think we can safely remove get_thread_id for all linux native targets.
Regression tested on arm-linux and aarch64-linux. Unable to build
native GDB and test it on xtensa-linux.

Remove get_thread_id
This patch removes get_thread_id from aarch64-linux-nat.c,
arm-linux-nat.c and xtensa-linux-nat.c.
get_thread_id was added in this commit below in 2000,
41c49b06c471443d3baf2eaa2463a315f9b5edca
https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html
which predates the ptid_t stuff added into GDB. Nowadays, lwpid of
inferior_ptid is only zero when the inferior is created (in
fork-child.c:fork_inferior) and its lwpid will be set after
linux_nat_wait_1 gets the first event. After that, lwpid of
inferior_ptid is not zero for linux-nat target, then we can use
ptid_get_lwp, so this function isn't needed anymore.
Even when GDB attaches to a process, the lwp of inferior_ptid
isn't zero, see linux-nat.c:linux_nat_attach,
/* The ptrace base target adds the main thread with (pid,0,0)
format. Decorate it with lwp info. */
ptid = ptid_build (ptid_get_pid (inferior_ptid),
ptid_get_pid (inferior_ptid),
0);
Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid
temperately for calling linux_ops->to_xfer_partial, but all the
affected functions in this patch are not called in
linux_ops->to_xfer_partial.
I think we can safely remove get_thread_id for all linux native targets.
Regression tested on arm-linux and aarch64-linux. Unable to build
native GDB and test it on xtensa-linux.

Convert have_ptrace_getregset to a tri-state boolean
have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have
some conditions like "if (have_ptrace_getregset)", which is not correct.
I'll explain why it is not correct in the following example. This fix
to this problem to replace the test (have_ptrace_getregset) to test
(have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc.
However Doug thinks it hinders readability
https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide
to add a new enum tribool and change have_ptrace_getregset to it, in
order to make these tests more readable.
have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in
$ARCH_linux_read_description according to the capability of the kernel.
However, it is possible that have_ptrace_getregset is used before it is
set to 0 or 1, which means it is still -1. This is shown below.

PTRACE_GETREGSET command is used even GDB doesn't know whether

Remove get_thread_id
This patch removes get_thread_id from aarch64-linux-nat.c,
arm-linux-nat.c and xtensa-linux-nat.c.
get_thread_id was added in this commit below in 2000,
41c49b06c471443d3baf2eaa2463a315f9b5edca
https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html
which predates the ptid_t stuff added into GDB. Nowadays, lwpid of
inferior_ptid is only zero when the inferior is created (in
fork-child.c:fork_inferior) and its lwpid will be set after
linux_nat_wait_1 gets the first event. After that, lwpid of
inferior_ptid is not zero for linux-nat target, then we can use
ptid_get_lwp, so this function isn't needed anymore.
Even when GDB attaches to a process, the lwp of inferior_ptid
isn't zero, see linux-nat.c:linux_nat_attach,
/* The ptrace base target adds the main thread with (pid,0,0)
format. Decorate it with lwp info. */
ptid = ptid_build (ptid_get_pid (inferior_ptid),
ptid_get_pid (inferior_ptid),
0);
Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid
temperately for calling linux_ops->to_xfer_partial, but all the
affected functions in this patch are not called in
linux_ops->to_xfer_partial.
I think we can safely remove get_thread_id for all linux native targets.
Regression tested on arm-linux and aarch64-linux. Unable to build
native GDB and test it on xtensa-linux.

Remove get_thread_id
This patch removes get_thread_id from aarch64-linux-nat.c,
arm-linux-nat.c and xtensa-linux-nat.c.
get_thread_id was added in this commit below in 2000,
41c49b06c471443d3baf2eaa2463a315f9b5edca
https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html
which predates the ptid_t stuff added into GDB. Nowadays, lwpid of
inferior_ptid is only zero when the inferior is created (in
fork-child.c:fork_inferior) and its lwpid will be set after
linux_nat_wait_1 gets the first event. After that, lwpid of
inferior_ptid is not zero for linux-nat target, then we can use
ptid_get_lwp, so this function isn't needed anymore.
Even when GDB attaches to a process, the lwp of inferior_ptid
isn't zero, see linux-nat.c:linux_nat_attach,
/* The ptrace base target adds the main thread with (pid,0,0)
format. Decorate it with lwp info. */
ptid = ptid_build (ptid_get_pid (inferior_ptid),
ptid_get_pid (inferior_ptid),
0);
Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid
temperately for calling linux_ops->to_xfer_partial, but all the
affected functions in this patch are not called in
linux_ops->to_xfer_partial.
I think we can safely remove get_thread_id for all linux native targets.
Regression tested on arm-linux and aarch64-linux. Unable to build
native GDB and test it on xtensa-linux.

Remove get_thread_id
This patch removes get_thread_id from aarch64-linux-nat.c,
arm-linux-nat.c and xtensa-linux-nat.c.
get_thread_id was added in this commit below in 2000,
41c49b06c471443d3baf2eaa2463a315f9b5edca
https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html
which predates the ptid_t stuff added into GDB. Nowadays, lwpid of
inferior_ptid is only zero when the inferior is created (in
fork-child.c:fork_inferior) and its lwpid will be set after
linux_nat_wait_1 gets the first event. After that, lwpid of
inferior_ptid is not zero for linux-nat target, then we can use
ptid_get_lwp, so this function isn't needed anymore.
Even when GDB attaches to a process, the lwp of inferior_ptid
isn't zero, see linux-nat.c:linux_nat_attach,
/* The ptrace base target adds the main thread with (pid,0,0)
format. Decorate it with lwp info. */
ptid = ptid_build (ptid_get_pid (inferior_ptid),
ptid_get_pid (inferior_ptid),
0);
Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid
temperately for calling linux_ops->to_xfer_partial, but all the
affected functions in this patch are not called in
linux_ops->to_xfer_partial.
I think we can safely remove get_thread_id for all linux native targets.
Regression tested on arm-linux and aarch64-linux. Unable to build
native GDB and test it on xtensa-linux.

Convert have_ptrace_getregset to a tri-state boolean
have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have
some conditions like "if (have_ptrace_getregset)", which is not correct.
I'll explain why it is not correct in the following example. This fix
to this problem to replace the test (have_ptrace_getregset) to test
(have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc.
However Doug thinks it hinders readability
https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide
to add a new enum tribool and change have_ptrace_getregset to it, in
order to make these tests more readable.
have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in
$ARCH_linux_read_description according to the capability of the kernel.
However, it is possible that have_ptrace_getregset is used before it is
set to 0 or 1, which means it is still -1. This is shown below.

Convert have_ptrace_getregset to a tri-state boolean
have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have
some conditions like "if (have_ptrace_getregset)", which is not correct.
I'll explain why it is not correct in the following example. This fix
to this problem to replace the test (have_ptrace_getregset) to test
(have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc.
However Doug thinks it hinders readability
https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide
to add a new enum tribool and change have_ptrace_getregset to it, in
order to make these tests more readable.
have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in
$ARCH_linux_read_description according to the capability of the kernel.
However, it is possible that have_ptrace_getregset is used before it is
set to 0 or 1, which means it is still -1. This is shown below.

Convert have_ptrace_getregset to a tri-state boolean
have_ptrace_getregset is a tri-state variable (-1, 0, 1), and we have
some conditions like "if (have_ptrace_getregset)", which is not correct.
I'll explain why it is not correct in the following example. This fix
to this problem to replace the test (have_ptrace_getregset) to test
(have_ptrace_getregset == 1) or (have_ptrace_getregset == -1) etc.
However Doug thinks it hinders readability
https://sourceware.org/ml/gdb-patches/2015-05/msg00692.html so I decide
to add a new enum tribool and change have_ptrace_getregset to it, in
order to make these tests more readable.
have_ptrace_getregset is initialised to -1, and is adjusted to 0 or 1 in
$ARCH_linux_read_description according to the capability of the kernel.
However, it is possible that have_ptrace_getregset is used before it is
set to 0 or 1, which means it is still -1. This is shown below.

Remove get_thread_id
This patch removes get_thread_id from aarch64-linux-nat.c,
arm-linux-nat.c and xtensa-linux-nat.c.
get_thread_id was added in this commit below in 2000,
41c49b06c471443d3baf2eaa2463a315f9b5edca
https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html
which predates the ptid_t stuff added into GDB. Nowadays, lwpid of
inferior_ptid is only zero when the inferior is created (in
fork-child.c:fork_inferior) and its lwpid will be set after
linux_nat_wait_1 gets the first event. After that, lwpid of
inferior_ptid is not zero for linux-nat target, then we can use
ptid_get_lwp, so this function isn't needed anymore.
Even when GDB attaches to a process, the lwp of inferior_ptid
isn't zero, see linux-nat.c:linux_nat_attach,
/* The ptrace base target adds the main thread with (pid,0,0)
format. Decorate it with lwp info. */
ptid = ptid_build (ptid_get_pid (inferior_ptid),
ptid_get_pid (inferior_ptid),
0);
Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid
temperately for calling linux_ops->to_xfer_partial, but all the
affected functions in this patch are not called in
linux_ops->to_xfer_partial.
I think we can safely remove get_thread_id for all linux native targets.
Regression tested on arm-linux and aarch64-linux. Unable to build
native GDB and test it on xtensa-linux.

Remove get_thread_id
This patch removes get_thread_id from aarch64-linux-nat.c,
arm-linux-nat.c and xtensa-linux-nat.c.
get_thread_id was added in this commit below in 2000,
41c49b06c471443d3baf2eaa2463a315f9b5edca
https://sourceware.org/ml/gdb-patches/2000-04/msg00398.html
which predates the ptid_t stuff added into GDB. Nowadays, lwpid of
inferior_ptid is only zero when the inferior is created (in
fork-child.c:fork_inferior) and its lwpid will be set after
linux_nat_wait_1 gets the first event. After that, lwpid of
inferior_ptid is not zero for linux-nat target, then we can use
ptid_get_lwp, so this function isn't needed anymore.
Even when GDB attaches to a process, the lwp of inferior_ptid
isn't zero, see linux-nat.c:linux_nat_attach,
/* The ptrace base target adds the main thread with (pid,0,0)
format. Decorate it with lwp info. */
ptid = ptid_build (ptid_get_pid (inferior_ptid),
ptid_get_pid (inferior_ptid),
0);
Note that linux_nat_xfer_partial shifts lwpid to pid for inferior_ptid
temperately for calling linux_ops->to_xfer_partial, but all the
affected functions in this patch are not called in
linux_ops->to_xfer_partial.
I think we can safely remove get_thread_id for all linux native targets.
Regression tested on arm-linux and aarch64-linux. Unable to build
native GDB and test it on xtensa-linux.

The Linux ptrace interface to hardware break-/watch-points presents the
|
|
|
|
values in a vector centred around 0 (which is used fo generic information).
|
|
|
|
Positive indicies refer to breakpoint addresses/control registers, negative
|
|
|
|
indices to watchpoint addresses/control registers.
|
|
|
|
|
|
|
|
The Linux vector is indexed as follows:
|
|
|
|
-((i << 1) + 2): Control register for watchpoint i.
|
|
|
|
-((i << 1) + 1): Address register for watchpoint i.
|
|
|
|
0: Information register.
|
|
|
|
((i << 1) + 1): Address register for breakpoint i.
|
|
|
|
((i << 1) + 2): Control register for breakpoint i.
|
|
|
|
|
|
|
|
This structure is used as a per-thread cache of the state stored by the
|
|
|
|
kernel, so that we don't need to keep calling into the kernel to find a
|
|
|
|
free breakpoint.
|
|
|
|
|
|
|
|
We treat break-/watch-points with their enable bit clear as being deleted.

Avoid software breakpoint's instruction shadow inconsistency
This change:
commit b775012e845380ed4c7421a1b87caf7bfae39f5f

* remote.c (remote_supports_cond_breakpoints): New forward
declaration.
[...]
changed the way breakpoints are inserted and removed such that
`insert_bp_location' can now be called with the breakpoint being handled
already in place, while previously the call was only ever made for
breakpoints that have not been put in place. This in turn caused an
issue for software breakpoints and targets for which a breakpoint's
`placed_address' may not be the same as the original requested address.
The issue is `insert_bp_location' overwrites the previously adjusted
value in `placed_address' with the original address, that is only
replaced back with the correct adjusted address later on when
`gdbarch_breakpoint_from_pc' is called. Meanwhile there's a window
where the value in `placed_address' does not correspond to data stored
in `shadow_contents', leading to incorrect instruction bytes being
supplied when `one_breakpoint_xfer_memory' is called to supply the
instruction overlaid by the breakpoint.
And this is exactly what happens on the MIPS target with software
breakpoints placed in microMIPS code. In this case not only
`placed_address' is not the original address because of the ISA bit, but
`mips_breakpoint_from_pc' has to read the original instruction to
determine which one of the two software breakpoint instruction encodings
to choose as well. The 16-bit encoding is used to replace 16-bit
instructions and similarly the 32-bit one is used with 32-bit
instructions, to satisfy branch delay slot size requirements.
The mismatch between `placed_address' and the address data in
`shadow_contents' has been obtained from leads to the wrong encoding
being used in some cases, which in the case of a 32-bit software
breakpoint instruction replacing a 16-bit instruction causes corruption
to the adjacent following instruction and leads the debug session astray
if execution reaches there e.g. with a jump.
To address this problem I made the change below, that adds a
`reqstd_address' field to `struct bp_target_info' and leaves
`placed_address' unchanged once it has been set. This ensures data in
`shadow_contents' is always consistent with `placed_address'.
This approach also has this good side effect that all the places that
examine the breakpoint's address see a consistent value, either
`reqstd_address' or `placed_address', as required. Currently some
places see either the original or the adjusted address in
`placed_address', depending on whether they have been called before
`gdbarch_remote_breakpoint_from_pc' or afterwards. This is in
particular true for subsequent calls to
`gdbarch_remote_breakpoint_from_pc' itself, e.g. from
`one_breakpoint_xfer_memory'. This is also important for places like
`find_single_step_breakpoint' where a breakpoint's address is compared
to the raw value of $pc.
* breakpoint.h (bp_target_info): Add `reqstd_address' member,
update comments.
* breakpoint.c (one_breakpoint_xfer_memory): Use `reqstd_address'
for the breakpoint's address. Don't preinitialize `placed_size'.
(insert_bp_location): Set `reqstd_address' rather than
`placed_address'.
(bp_target_info_copy_insertion_state): Also copy `placed_address'.
(bkpt_insert_location): Use `reqstd_address' for the breakpoint's
address.

* mem-break.c (default_memory_insert_breakpoint): Use
`reqstd_address' for the breakpoint's address. Don't set
`placed_address' or `placed_size' if breakpoint contents couldn't
have been determined.
* remote.c (remote_insert_breakpoint): Use `reqstd_address' for
the breakpoint's address.
(remote_insert_hw_breakpoint): Likewise. Don't set
`placed_address' or `placed_size' if breakpoint couldn't have been
set.

`reqstd_address' for the breakpoint's address.

add "this" pointers to more target APIs
A subsequent pass introduces delegation helper functions to the target
API. This delegation is much cleaner if the target_ops pointer is
directly available at delegation time.
This patch adds the "this" pointer to various to_* methods for this
purpose.
This updates a number of ports which I am unable to test. Please give
them a look-over. Any possible problem here is trivial, though, as
all that is required is adding an argument to a function.
