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 other registers with other info (e.g., nip is filled with
the contents of TFHAR). GDB doesn't handle these other registers.
This means that core files generated by GDB will show values of zero
for these registers, while core files generated by the kernel will
have other values. 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).

+The @samp{org.gnu.gdb.power.htm.altivec} feature is optional. It
+should contain the checkpointed altivec registers @samp{cvr0} through
+@samp{cvr31}, all 128-bit wide. It should also contain the
+checkpointed registers @samp{cvscr} and @samp{cvrsave}, both 32-bit
+wide.
+
+The @samp{org.gnu.gdb.power.htm.vsx} feature is optional. It should
+contain registers @samp{cvs0h} through @samp{cvs31h}. @value{GDBN}
+will combine these registers with the checkpointed floating point
+registers (@samp{cf0} through @samp{cf31}) and the checkpointed
+altivec registers (@samp{cvr0} through @samp{cvr31}) to present the
+128-bit wide checkpointed vector-scalar registers @samp{cvs0} through
+@samp{cvs63}. Therefore, this feature requires both
+@samp{org.gnu.gdb.power.htm.altivec} and
+@samp{org.gnu.gdb.power.htm.fpu}.
+
+The @samp{org.gnu.gdb.power.htm.ppr} feature is optional. It should
+contain the 64-bit checkpointed register @samp{cppr}.
+
+The @samp{org.gnu.gdb.power.htm.dscr} feature is optional. It should
+contain the 64-bit checkpointed register @samp{cdscr}.
+
+The @samp{org.gnu.gdb.power.htm.tar} feature is optional. It should
+contain the 64-bit checkpointed register @samp{ctar}.
