2019-03-06Remove last cleanup from gdbserverTom Tromey2-5/+11
This removes the last cleanup from gdbserver, replacing it with SCOPE_EXIT. This could perhaps be done in a different way, but this approach was direct and obviously correct. 2019-03-06 Tom Tromey <tom@tromey.com> * server.c (detach_or_kill_for_exit_cleanup): Remove parameter. (captured_main): Use SCOPE_EXIT.
2019-03-04Use '$enable_unittest' instead of '$development' on gdbserver/configure.srv ↵Sergio Durigan Junior2-1/+7
(for 'aarch64*-*-linux*' case) On commit 8ecfd7bd4acd69213c06fac6de9af38299123547 ("Add parameter to allow enabling/disabling selftests via configure") it seems that I forgot to use the proper '$enable_unittest' variable when checking to see whether to add selftest-related objects to 'srv_regobj'. This causes a build failure on Aarch64 when 'development=false' (which is the case for the 8.3 branch) and 'enable_unittest=true'. This patch fixes the problem by using '$enable_unittest' instead of '$development' when performing the check. As a reminder, it's important to notice that '$enable_unittest's default value (i.e., when the option '--enable-unit-tests' is not passed to configure) is the same as '$development', so this patch doesn't affect the current build. I'd like to install this patch both on master and on the 8.3 branch. OK? gdb/gdbserver/ChangeLog: 2019-03-04 Sergio Durigan Junior <sergiodj@redhat.com> * configure.srv: Use '$enable_unittest' instead of '$development' when checking whether to fill 'srv_regobj' on 'aarch64*-*-linux*' case.
2019-03-02Fix GDB compilation on MinGW (PR gdb/24292)Eli Zaretskii2-4/+10
gdb/ChangeLog: 2019-03-02 Eli Zaretskii <eliz@gnu.org> PR gdb/24292 * common/netstuff.c: * gdbserver/gdbreplay.c * gdbserver/remote-utils.c: * ser-tcp.c: * unittests/parse-connection-spec-selftests.c [USE_WIN32API]: Include ws2tcpip.h instead of wsiapi.h and winsock2.h. Redefine _WIN32_WINNT to 0x0501 if defined to a smaller value, as 'getaddrinfo' and 'freeaddrinfo' were not available before Windows XP, and mingw.org's MinGW headers by default define _WIN32_WINNT to 0x500.
2019-02-27Handle \r\n in gdbreplayTom Tromey2-2/+22
I tried gdbreplay yesterday, but the remotelogfile I received was made on Windows, so the lines were terminated with \r\n rather than plain \n. This patch changes gdbreplay to allow \r\n line termination when reading the log file. gdb/gdbserver/ChangeLog 2019-02-27 Tom Tromey <tromey@adacore.com> * gdbreplay.c (logchar): Handle \r\n.
2019-02-07gdbserver: When attaching, add process before lwpsAlan Hayward3-3/+12
The recent BP/WP changes for AArch64 swapping the order in add_lwp() so that the process was added before the lwp. This was due to the lwp creation requiring the process data. This also needs changing in linux_attach(). Also add additional checks to make sure cannot attach to the same process twice. Add test case for this - do this by splitting attach.exp into distinct pass and error case sections. Fixes gdb.server/ext-attach.exp on Aarch64. gdb/gdbserver/ChangeLog: * linux-low.c (linux_attach): Add process before lwp. * server.c (attach_inferior): Check if already attached. gdb/testsuite/ChangeLog: * gdb.base/attach.exp: Add double attach test.
2019-02-07Normalize include guards in gdbTom Tromey31-61/+142
While working on my other scripts to deal with gdb headers, I noticed that some files were missing include guards. I wrote a script to add the missing ones, but found that using the obvious names for the guards ran into clashes -- for example, gdb/nat/linux-nat.h used "LINUX_NAT_H", but this was also the script's choice for gdb/linux-nat.h. So, I changed the script to normalize all include guards in gdb. This patch is the result. As usual the script is available here: https://github.com/tromey/gdb-refactoring-scripts Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the buildbot. gdb/ChangeLog 2019-02-07 Tom

2019-01-30[PR gdb/23985] Fix libinproctrace.so buildSzabolcs Nagy2-0/+12
The IPA objects currently may use gnulib replacement apis, which is wrong: gnulib is not linked into the produced dso and it cannot be because it is not built with -fPIC -fvisibility=hidden. The gnulib replacement detection is broken under cross compilation: for targets other than *-gnu*, replacements are enabled that depend on execution time detection. This causes unnecessary build failure when the target has proper support for the replaced api. This fix tries to undo the replacements, which is tricky because the gnulib headers are still used for various compile time fixups and there is no simple knob in gnulib to only turn the replacements off. Without this workaround gdb fails to cross build to non-gnu targets: ld: tracepoint-ipa.o: in function `gdb_agent_helper_thread(void*)': gdb/gdbserver/tracepoint.c:7221: undefined reference to `rpl_strerror' ... Makefile:434: recipe for target 'libinproctrace.so' failed gdb/gdbserver/ChangeLog: PR gdb/23985 * Makefile.in (IPAGENT_CFLAGS): Add UNDO_GNULIB_CFLAGS. (UNDO_GNULIB_CFLAGS): Undo gnulib replacements.

2018-12-05AArch64: Racy: Don't set empty set of hardware BPs/WPs on new threadAlan Hayward2-2/+6
On some heavily loaded AArch64 boxes, GDB will sometimes hang forever when the inferior creates a thread. This hang happens inside the kernel during the ptrace call to set hardware watchpoints or hardware breakpoints. Currently, GDB will always set hw wp/bp at the start of each thread even if there are none set in the process. This patch works around the issue by avoiding setting hw wp/bp if there are none set for the process. On an effected machine, this fix drastically reduces the racy nature of the gdb.threads test set. I ran the entire gdb test suite across all processors for 100 iterations, then ran the results through the racy tests script. Without the patch, 58 .exp files in gdb.threads were marked as racy. After the patch this reduced to the same ~14 tests as the non effected boxes. Clearly GDB will still be subject to hangs on an effect box if hw wp/bp's are used prior to creating inferior threads on a heavily loaded system. To enable this in gdbserver, the sequence in gdbserver add_lwp() is switched to the same as gdb order as gdb, to ensure the thread is registered before calling new_thread(). This allows aarch64_linux_new_thread() to read the ptid. gdb/ChangeLog: * nat/aarch64-linux-hw-point.c (aarch64_linux_any_set_debug_regs_state): New function. * nat/aarch64-linux-hw-point.h (aarch64_linux_any_set_debug_regs_state): New declaration. * nat/aarch64-linux.c (aarch64_linux_new_thread): Check if any BPs or WPs are set. gdb/gdbserver/ChangeLog: * linux-low.c (add_lwp): Switch ordering.

2018-10-26[PowerPC] Add support for HTM registersEdjunior Barbosa Machado5-2/+279
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.

2018-10-26[PowerPC] Add support for EBB and PMU registersEdjunior Barbosa Machado3-1/+85
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.

2018-10-10Add parameter to allow enabling/disabling selftests via configureSergio Durigan Junior6-8/+46
This is a follow-up of: https://sourceware.org/ml/gdb-patches/2018-08/msg00347.html Instead of going throttle and always enabling our selftests (even in non-development builds), this patch is a bit more conservative and introduces a configure option ("--enable-unit-tests") that allows the user to choose whether she wants unit tests in the build or not. Note that the current behaviour is retained: if no option is provided, GDB will have selftests included in a development build, and will *not* have selftests included in a non-development build. The rationale for having this option is still the same: due to the many racy testcases and random failures we see when running the GDB testsuite, it is unfortunately not possible to perform a full test when one is building a downstream package. As the Fedora GDB maintainer and one of the Debian GDB uploaders, I feel like this situation could be improved by, at least, executing our selftests after the package has been built. This patch introduces no regressions to our build.

2018-09-05Make -Wformat-nonliteral work with gccTom Tromey2-1/+14
After looking into why the build failed for Simon but not for me, we found that the underlying cause was due to how gcc treats -Wformat-nonliteral. gcc requires -Wformat to be given first; but warning.m4 was not doing this, so -Wformat-nonliteral was not being used. This patch changes warning.m4 to account gcc's requirement. This then showed that the target-float.c build change in the earlier Makefile patch was also incorrect. Simon didn't see this in his build, but gcc now points it out. So, this patch fixes this problem as well. 2018-09-05 Tom Tromey <tom@tromey.com> * warning.m4 (AM_GDB_WARNINGS): Add -Wformat when testing -Wformat-nonliteral. * target-float.c (host_float_ops<T>::to_string) (host_float_ops<T>::from_string): Use DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL. * configure: Rebuild. gdb/gdbserver/ChangeLog 2018-09-05 Tom Tromey <tom@tromey.com> * configure: Rebuild.

This patch renames the version in common to ipa_sym_addresses_common to avoid the name clash.

2018-08-22Restore behavior of disabling address randomization by default on GDBserverSimon Marchi2-1/+8
Commit c12a508 ("Add client_state struct.") inadvertently changed the default behavior of GDBserver wrt address randomization. The old disable_randomization global variable was initialized to 1, whereas the corresponding field in the client_state structure is initialized to 0. This fixes make check TESTS="gdb.base/jit-simple.exp" RUNTESTFLAGS="--target_board=native-gdbserver" make check TESTS="gdb.base/execl-update-breakpoints.exp" RUNTESTFLAGS="--target_board=native-gdbserver" Note that the execl-update-breakpoints.exp would only fail on systems where the toolchain emits position-independent executables by default (otherwise the main executable position is never randomized, so the value of disable_randomization didn't matter). gdb/gdbserver/ChangeLog: PR gdb/23374 PR gdb/23375 * server.h (struct client_state) <disable_randomization>: Initialize to 1.

2018-07-22Remove unused variables from gdbserverTom Tromey6-9/+21
This removes a few unused variables from gdbserver. The x86-tdesc.h change is a bit unusual for this series. This file was not defining the multiple-include guard symbol, so I've added that here. Also, it is hard to determine when i386_expedite_regs will be needed, so this patch simply marks it ATTRIBUTE_UNUSED. gdb/gdbserver/ChangeLog 2018-07-22 Tom Tromey <tom@tromey.com> * win32-low.c (win32_create_inferior): Remove unused variables. * gdbreplay.c (remote_open): Remove unused variable. * remote-utils.c (remote_prepare): Remove unused variable. * x86-tdesc.h (X86_TDESC_H): Define.

2018-07-11Implement IPv6 support for GDB/gdbserverSergio Durigan Junior4-65/+205
This patch implements IPv6 support for both GDB and gdbserver. Based on my research, it is the fourth attempt to do that since 2006. Since I used ideas from all of the previous patches, I also added their authors's names on the ChangeLogs as a way to recognize their efforts. For reference sake, you can find the previous attempts at: https://sourceware.org/ml/gdb-patches/2006-09/msg00192.html https://sourceware.org/ml/gdb-patches/2014-02/msg00248.html https://sourceware.org/ml/gdb-patches/2016-02/msg00226.html The basic idea behind the patch is to start using the new 'getaddrinfo'/'getnameinfo' calls, which are responsible for translating names and addresses in a protocol-independent way. This means that if we ever have a new version of the IP protocol, we won't need to change the code again (or, at least, won't have to change the majority of the code). The function 'getaddrinfo' returns a linked list of possible addresses to connect to. Dealing with multiple addresses proved to be a hard task with the current TCP auto-retry mechanism implemented on ser-tcp:net_open. For example, when gdbserver listened only on an IPv4 socket: $ ./gdbserver --once 127.0.0.1:1234 ./a.out and GDB was instructed to try to connect to both IPv6 and IPv4 sockets: $ ./gdb -ex 'target extended-remote localhost:1234' ./a.out the user would notice a somewhat big delay before GDB was able to connect to the IPv4 socket. This happened because GDB was trying to connect to the IPv6 socket first, and had to wait until the connection timed out before it tried to connect to the IPv4 socket. For that reason, I had to rewrite the main loop and implement a new method for handling multiple connections. After some discussion, Pedro and I agreed on the following algorithm: 1) For each entry returned by 'getaddrinfo', we try to open a socket and connect to it. 2.a) If we have a successful 'connect', we just use that connection. 2.b) If we don't have a successfull 'connect', but if we've got a ECONNREFUSED (meaning the the connection was refused), we keep track of this fact by using a flag. 2.c) If we don't have a successfull 'connect', but if we've got a EINPROGRESS (meaning that the connection is in progress), we perform a 'select' call on the socket until we have a result (either a successful connection, or an error on the socket). 3) If tcp_auto_retry is true, and we haven't gotten a successful connection, and at least one of our attempts failed with ECONNREFUSED, then we wait a little bit (i.e., call 'wait_for_connect'), check to see if there was a timeout/interruption (in which case we bail out), and then go back to (1). After multiple tests, I was able to connect without delay on the scenario described above, and was also able to connect in all other types of scenarios. I also implemented some hostname parsing functions (along with their corresponding unit tests) which are used to help GDB and gdbserver to parse hostname strings provided by the user. These new functions are living inside common/netstuff.[ch]. I've had to do that since IPv6 introduces a new URL scheme, which defines that square brackets can be used to enclose the host part and differentiate it from the port (e.g., "[::1]:1234" means "host ::1, port 1234"). I spent some time thinking about a reasonable way to interpret what the user wants, and I came up with the following: - If the user has provided a prefix that doesn't specify the protocol version (i.e., "tcp:" or "udp:"), or if the user has not provided any prefix, don't make any assumptions (i.e., assume AF_UNSPEC when dealing with 'getaddrinfo') *unless* the host starts with "[" (in which case, assume it's an IPv6 host). - If the user has provided a prefix that does specify the protocol version (i.e., "tcp4:", "tcp6:", "udp4:" or "udp6:"), then respect that. This method doesn't follow strictly what RFC 2732 proposes (that literal IPv6 addresses should be provided enclosed in "[" and "]") because IPv6 addresses still can be provided without square brackets in our case, but since we have prefixes to specify protocol versions I think this is not an issue. Another thing worth mentioning is the new 'GDB_TEST_SOCKETHOST' testcase parameter, which makes it possible to specify the hostname (without the port) to be used when testing GDB and gdbserver. For example, to run IPv6 tests: $ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp6:[::1]' Or, to run IPv4 tests: $ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp4:127.0.0.1' This required a few changes on the gdbserver-base.exp, and also a minimal adjustment on gdb.server/run-without-local-binary.exp. Finally, I've implemented a new testcase, gdb.server/server-connect.exp, which is supposed to run on the native host and perform various "smoke tests" using different connection methods. This patch has been regression-tested on BuildBot and locally, and also built using a x86_64-w64-mingw32 GCC, and no problems were found. gdb/ChangeLog: 2018-07-11 Sergio Durigan Junior <sergiodj@redhat.com> Jan Kratochvil <jan.kratochvil@redhat.com> Paul Fertser <fercerpav@gmail.com> Tsutomu Seki <sekiriki@gmail.com> Pedro Alves <palves@redhat.com> * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add 'unittests/parse-connection-spec-selftests.c'.

2018-07-11GDBserver: Don't assume a current process in D;PID implementation (PR gdb/23377)Pedro Alves4-24/+40
This fixes a gdb.base/multi-forks.exp regression with GDBserver. Git commit f2ffa92bbce9 ("gdb: Eliminate the 'stop_pc' global") caused the regression by exposing a latent bug in gdbserver. The bug is that GDBserver's implementation of the D;PID packet incorrectly assumes that the selected thread points to the process being detached. This happens via the any_persistent_commands call, which calls current_process: (gdb) bt #0 0x000000000040a57e in internal_error(char const*, int, char const*, ...) (file=0x4a53c0 "src/gdb/gdbserver/inferiors.c", line=212, fmt=0x4a539e "%s: Assertion `%s' failed.") at src/gdb/gdbserver/../common/errors.c:54 #1 0x0000000000420acf in current_process() () at src/gdb/gdbserver/inferiors.c:212 #2 0x00000000004226a0 in any_persistent_commands() () at gdb/gdbserver/mem-break.c:308 #3 0x000000000042cb43 in handle_detach(char*) (own_buf=0x6f0280 "D;62ea") at src/gdb/gdbserver/server.c:1210 #4 0x0000000000433af3 in process_serial_event() () at src/gdb/gdbserver/server.c:4055 #5 0x0000000000434878 in handle_serial_event(int, void*) (err=0, client_data=0x0) The "eliminate stop_pc" commit exposes the problem because before that commit, GDB's switch_to_thread always read the newly-selected thread's PC, and that would end up forcing GDBserver's selected thread to change accordingly as side effect. After that commit, GDB no longer reads the thread's PC, and GDBserver does not switch the thread. Fix this by removing the assumption from GDBserver. gdb/gdbserver/ChangeLog: 2018-07-11 Pedro Alves <palves@redhat.com> PR gdb/23377 * mem-break.c (any_persistent_commands): Add process_info parameter and use it instead of relying on the current process.

For some such registers we're masking off the uninitialized bits with 0xffff, but not in all cases. We end up in such a fragile situation because collect_registers_by_name works with an untyped output buffer pointer, making it easy to pass a pointer to a variable of the wrong size. Fix this by using regcache_raw_get_unsigned instead (actually a new regcache_raw_get_unsigned_by_name wrapper), which always returns a zero-extended ULONGEST register value.
