[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).

[PowerPC] Add support for EBB and PMU registers
This patch adds support for registers of the Event Based Branching and
Performance Monitoring Units for the powerpc linux native and core
file targets, and for the powerpc linux server stub.
All three EBB registers are accessible. Only a subset of the PMU
registers can be accessed through ptrace. Because of this, the PMU
registers are enumerated individually in gdbarch_tdep, as opposed to
having a single "have_pmu" flag. This is intended to make it easier
to add additional PMU registers in the future, since checking a
"have_pmu" flag elsewhere in the code would no longer be correct. The
tdesc feature is named org.gnu.gdb.power.linux.pmu because of this.
It's unclear if it makes sense to save and restore these registers
across function calls, since some of them can be modified
asynchronously. They are also not tracked in record-replay mode.
The kernel can return ENODATA when ptrace is used to get the EBB
registers, unless a linux performance event that uses EBB is open in
the inferior. For this reason, the "fill" functions in the server
stub for the ebb register sets is not implemented.
Since gdbserver writes all registers in one go before resuming the
inferior, this error would not be detected at the time the user tries
to write to one of the registers on the client side, and gdbserver
would print out warnings every time it resumes the inferior when no
ebb performance event is opened, so there is currently no
straightforward way to handle this case. This means the ebb registers
in the client-side regcache can become dirty when the user tries to
write to them, until the inferior is resumed and stopped again.
A related issue is that 'G' packets used to write to unrelated
registers will include bad data for the EBB registers if they are
unavailable, since no register status information is included in the
'G' packet. This data won't be written to the inferior by the
gdbserver stub because the "fill" functions are not implemented, and
currently the gdbserver stub doesn't change the status of the
registers in its own regcache in response to 'G' packets.
Another limitation for the ebb registers is that traceframes don't
record if registers are available or not, so if these registers are
collected when a tracepoint is hit and the inferior has no ebb event
opened, the user will see zero values for all of them, instead of the
usual <unavailable>.
Because these registers are often unavailable, trying to store them
with target_store_registers with -1 for the regno argument (all
registers) would almost always fail, so they are ignored in this case.

[PowerPC] Add support for HTM registers
This patch adds support for Hardware Transactional Memory registers
for the powerpc linux native and core file targets, and for the
pwoerpc linux server stub.
These registers include both the HTM special-purpose registers (TFHAR,
TEXASR and TFIAR) as well as the set of registers that are
checkpointed (saved) when a transaction is initiated, which the
processor restores in the event of a transaction failure.
The set of checkpointed general-purpose registers is returned by the
linux kernel in the same format as the regular general-purpose
registers, defined in struct pt_regs. However, the architecture
specifies that only some of the registers present in pt_regs are
checkpointed (GPRs 0-31, CR, XER, LR and CTR). The kernel fills the
slots for MSR and NIP with other info. The other fields usually don't
have meaningful values. GDB doesn't define registers that are not
checkpointed in the architecture, but when generating a core file, GDB
fills the slot for the checkpointed MSR with the regular MSR. These
are usually similar, although some bits might be different, and in
some cases the checkpointed MSR will have a value of 0 in a
kernel-generated core-file. The checkpointed NIP is filled with TFHAR
by GDB in the core-file, which is what the kernel does. The other
fields are set to 0 by GDB.
Core files generated by the kernel have a note section for
checkpointed GPRs with the same size for both 32-bit and 64-bit
threads, and the values for the registers of a 32-bit thread are
squeezed in the first half, with no useful data in the second half.
GDB generates a smaller note section for 32-bit threads, but can read
both sizes.
The checkpointed XER is required to be 32-bit in the target
description documentation, even though the more recent ISAs define it
as 64-bit wide, since the high-order 32-bits are reserved, and because
in Linux there is no way to get a 64-bit checkpointed XER for 32-bit
threads. If this changes in the future, the target description
feature requirement can be relaxed to allow for a 64-bit checkpointed
XER.
Access to the checkpointed CR (condition register) can be confusing.
The architecture only specifies that CR fields 1 to 7 (the 24 least
significant bits) are checkpointed, but the kernel provides all 8
fields (32 bits). The value of field 0 is not masked by ptrace, so it
will sometimes show the result of some kernel operation, probably
treclaim., which sets this field.
The checkpointed registers are marked not to be saved and restored.
Inferior function calls during an active transaction don't work well,
and it's unclear what should be done in this case. TEXASR and TFIAR
can be altered asynchronously, during transaction failure recording,
so they are also not saved and restored. For consistency neither is
TFHAR.
Record and replay also doesn't work well when transactions are
involved. This patch doesn't address this, so the values of the HTM
SPRs will sometimes be innacurate when the record/relay target is
enabled. For instance, executing a "tbegin." alters TFHAR and TEXASR,
but these changes are not currently recorded.
Because the checkpointed registers are only available when a
transaction is active (or suspended), ptrace can return ENODATA when
gdb tries to read these registers and the inferior is not in a
transactional state. The registers are set to the unavailable state
when this happens. When gbd tries to write to one of these registers,
and it is unavailable, an error is raised.
The "fill" functions for checkpointed register sets in the server stub
are not implemented for the same reason as for the EBB register set,
since ptrace can also return ENODATA for checkpointed regsets. The
same issues with 'G' packets apply here.
Just like for the EBB registers, tracepoints will not mark the
checkpointed registers as unavailable if the inferior was not in a
transaction, so their content will also show 0 instead of
<unavailable> when inspecting trace data.
The new tests record the values of the regular registers before
stepping the inferior through a "tbegin." instruction to start a
transaction, then the checkpointed registers are checked against the
recorded pre-transactional values. New values are written to the
checkpointed registers and recorded, the inferior continues until the
transaction aborts (which is usually immediately when it is resumed),
and the regular registers are checked against the recorded values,
because the abort should have reverted the registers to these values.
Like for the EBB registers, target_store_registers will ignore the
checkpointed registers when called with -1 as the regno
argument (store all registers in one go).
