Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files. |

[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). gdb/ChangeLog: 2018-10-26 Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com> Pedro Franco de Carvalho <pedromfc@linux.ibm.com> * arch/ppc-linux-tdesc.h (tdesc_powerpc_isa207_htm_vsx32l) (tdesc_powerpc_isa207_htm_vsx64l): Declare. * arch/ppc-linux-common.h (PPC_LINUX_SIZEOF_TM_SPRREGSET) (PPC32_LINUX_SIZEOF_CGPRREGSET, PPC64_LINUX_SIZEOF_CGPRREGSET) (PPC_LINUX_SIZEOF_CFPRREGSET, PPC_LINUX_SIZEOF_CVMXREGSET) (PPC_LINUX_SIZEOF_CVSXREGSET, PPC_LINUX_SIZEOF_CPPRREGSET) (PPC_LINUX_SIZEOF_CDSCRREGSET, PPC_LINUX_SIZEOF_CTARREGSET): Define.

[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. gdb/ChangeLog: 2018-10-26 Edjunior Barbosa Machado <emachado@linux.vnet.ibm.com> Pedro Franco de Carvalho <pedromfc@linux.ibm.com> * arch/ppc-linux-common.h (PPC_LINUX_SIZEOF_EBBREGSET) (PPC_LINUX_SIZEOF_PMUREGSET): Declare. * nat/ppc-linux.h (PPC_FEATURE2_EBB, NT_PPC_EBB, NT_PPC_PMU): Define if not already defined. * features/rs6000/power-ebb.xml: New file. * features/rs6000/power-linux-pmu.xml: New file. * features/rs6000/powerpc-isa207-vsx32l.xml: Include ebb and pmu features. * features/rs6000/powerpc-isa207-vsx64l.xml: Likewise. * features/rs6000/powerpc-isa207-vsx32l.c: Re-generate. * features/rs6000/powerpc-isa207-vsx64l.c: Re-generate. * regformats/rs6000/powerpc-isa207-vsx32l.dat: Re-generate. * regformats/rs6000/powerpc-isa207-vsx64l.dat: Re-generate. * ppc-linux-nat.c (fetch_register, fetch_ppc_registers): Call fetch_regset with ebb and pmu regsets.

[PowerPC] Fix access to VSCR in linux targets
The 4-byte VSCR register is found inside a 16-byte field in the regset returned by ptrace and in core files. The position of VSCR depends on the endianess of the target, which was previously assumed to be big-endian for the purpose of getting VSCR. This patch removes this assumption to fix access to VSCR in little-endian mode. gdb/ChangeLog: 2018-05-22 Pedro Franco de Carvalho <pedromfc@linux.vnet.ibm.com> * ppc-tdep.h (struct ppc_reg_offsets): Remove vector register offset fields. * ppc-fbsd-tdep.c (ppc32_fbsd_reg_offsets): Remove initializers for vector register offset fields.

[PowerPC] Consolidate linux target description selection
Share target description declarations and selection among ppc linux native targets, core files, gdbserver and IPA. To avoid complicated define guards, gdbserver and IPA now have declarations for all descriptions, including 64-bit generated descriptions when compiled in 32-bit mode. These have always been linked into the gdbserver and IPA binaries. Because they might be uninitialized, the selection function checks that the selected description is initialized. gdb/ChangeLog: 2018-05-22 Pedro Franco de Carvalho <pedromfc@linux.vnet.ibm.com> * arch/ppc-linux-common.c: New file. * arch/ppc-linux-common.h: New file. * arch/ppc-linux-tdesc.h: New file. * configure.tgt (powerpc*-*-linux*): Add arch/ppc-linux-common.o. * Makefile.in (ALL_TARGET_OBS): Add arch/ppc-linux-common.o.
