Yury Khrustalev	4792a423d2	aarch64: Add support for (M)ADDPT and (M)SUBPT instructions The following instructions are added in this patch: - ADDPT and SUBPT - Add/Subtract checked pointer - MADDPT and MSUBPT - Multiply Add/Subtract checked pointer These instructions are part of Checked Pointer Arithmetic extension. This patch adds assembler and disassembler support for these instructions with relevant checks. Tests are included as well. A new flag "+cpa" added to documentation. This flag enables CPA extension. Regression tested on the aarch64-none-linux-gnu target and no regressions have been found.	2 years ago

Tom Tromey	38ad466f70	Remove some unnecessary Ada expression code ada_bitwise_operation differs from the "usual" bitwise operations only in that it calls value_cast at the end. However, because gdb is generally fairly lax about integer types, and because (perhaps oddly) C-style binary promotion is done here anyway, it seems to me that this code isn't needed.	2 years ago
Tom Tromey	1dd09e7f70	Fix Ada 'ptype' of access to array ptype is a bit funny, in that it accepts both expressions and type names. It also evaluates the resulting expression using EVAL_AVOID_SIDE_EFFECTS -- which both seems sensible (as a user would you expect ptype to possibly cause inferior execution?), but is also a historical artifact of how expressions are implemented (there's no EVAL_FOR_TYPE). In Ada, calling a function with an array will sometimes result in a "thick pointer" array descriptor being made. This is essentially a structure holding a pointer and bounds information. Currently, in such a callee, printing the type of the array will yield funny results: (gdb) print str.all $1 = "Hello World" (gdb) ptype str type = array (<>) of character (gdb) ptype str.all type = array (1 .. 0) of character That "1 .. 0" is the result of an EVAL_AVOID_SIDE_EFFECTS branch trying to do "something" with an array descriptor, without doing too much. I tried briefly to make this code really dereference the array descriptor and get the correct runtime type. However, that proved to be tricky; it certainly can't be done for all access types, because that will cause dynamic type resolution and end up printing just the runtime type -- which with variants may be pretty far from what the user may expect. Instead, this patch arranges to just leave such types alone in this situation. I don't think this should have an extra effects, because things like array subscripting still work on thick pointers. This patch also touches arrayptr.exp, because in that case the access type is a "thin pointer", and this ensures that the output does not change in that scenario.	2 years ago
Tom Tromey	2b5f0fe323	Use string_view in quirk_rust_enum quirk_rust_enum makes string copies to store in an unordered_map. However, the original strings have an appropriate lifetime, and so no copying is needed. With C++17, we can rely on string_view having a std::hash specialization, so this patch changes this code to use string_view rather than string.	2 years ago

Tom Tromey	2518ce9470	Clear board_info entry after waiting for process When certain DAP tests are run in a certain order, dejagnu will throw an exception during shutdown. After adding many logging statements, I tracked this down to kill_wait_spawned_process not clearing the 'fileid' board_info entry, causing dejagnu to try to wait for the process a second time -- and fail. Tom de Vries then pointed out a second instance of this, which I tracked down to the same problem occurring when spawning gdbserver. This version of the patch fixes this by adding a new proc that can be used to clean up board_info after waiting for a process to exit. I'm not sure why this problem hasn't affected the test suite in the past. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=31435 Approved-By: Andrew Burgess <aburgess@redhat.com>	2 years ago
Clément Chigot	d0eb2625bf	bfd: add missing include <time.h> bdfio.c is defining bfd_get_current_time which is returning a time_t.

Andrew Burgess	93eb6c64ec	gdb/testsuite: attach to i386 process stopped in vDSO Fedora GDB has carried around a patch for a while which tested attaching to an i386 process which is stopped within the vDSO library region. Apparently, at some point in the distant past there was an issue finding symbol information for this region in this situation. I'm struggling to track down the precise details of what the original bug was, however, acquiring symbol information for the vDSO region is different than for "normal" shared libraries -- the vDSO information is synthesised within GDB during the attach / inferior creation process -- so it's not unreasonable to imagine that there could be a bug specifically in this area of GDB which wouldn't impact "normal" shared libraries. I looked for references to vDSO in our testsuite and couldn't find any tests that looked like they did the same sort of thing, so I'd like to propose adding this test to our testsuite. It's a pretty simple test, and doesn't take long to run, so the cost of adding this is not huge. Approved-By: Tom Tromey <tom@tromey.com>	2 years ago

Simon Marchi	da48217f31	gdbserver/linux: probe for libiconv in configure Make gdbserver's build system locate libiconv when building for Linux. Commit `07b3255c3b` ("Filter invalid encodings from Linux thread names") make libiconv madantory for building gdbserver on Linux. While trying to cross-compile gdb for xtensa-fsf-linux-uclibc (with a toolchain generated with crosstool-ng), I got: /home/smarchi/src/binutils-gdb/gdbserver/linux-low.cc:48:10: fatal error: iconv.h: No such file or directory 48 \| #include <iconv.h> \| ^~~~~~~~~ I downloaded GNU libiconv, built it for that host, and installed it in an arbitrary directory. I had to modify the gdbserver build system to locate libiconv and use it, the result is this patch. I eventually found that crosstool-ng has a config option to make uclibc provide an implementation of iconv, which is of course much easier. But given that this patch is now written, I think it would be worth merging it, it could help some people who do not have iconv built-in their libc in the future (and may not have the luxury of rebuilding their libc like I do). Using AM_ICONV in configure.ac adds these options for configure (the same we have for gdb): --with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib --without-libiconv-prefix don't search for libiconv in includedir and libdir --with-libiconv-type=TYPE type of library to search for (auto/static/shared) It sets the `LIBICONV` variable with whatever is needed to link with libiconv, and adds the necessary `-I` flag to `CPPFLAGS`. To avoid unnecessarily linking against libiconv on hosts that don't need it, set `MAYBE_LIBICONV` with the contents of `LIBICONV` only if the host is Linux, and use `MAYBE_LIBICONV` in `Makefile.in`. Since libiconv is a hard requirement for Linux hosts, error out if it is not found. The bits in acinclude.m4 are similar to what we have in gdb/acinclude.m4. Update the top-level build system to support building against an in-tree libiconv (I did not test this part though). Something tells me that the all-gdbserver dependency on all-libiconv is unnecessary, since there is already a dependency of configure-gdbserver on all-libiconv (and all-gdbserver surely depends on configure-gdbserver). I just copied what's done for GDB though. ChangeLog: * Makefile.def: Add configure-gdbserver and all-gdbserver dependencies on all-libiconv. * Makefile.in: Re-generate.

Tom Tromey	b0e7d28eae	Remove 'if' from GDB_PY_HANDLE_EXCEPTION This removes the embedded 'if' from GDB_PY_HANDLE_EXCEPTION and GDB_PY_SET_HANDLE_EXCEPTION. I believe this 'if' was necessary with the old gdb try/catch macros, but it no longer is: these should only ever be called from a 'catch' block, where it's already known that an exception was thrown. Simon pointed out, though, that in a few spots, these were in facts called outside of 'catch' blocks. This patch cleans up these spots. I also found one spot where a redundant 'return nullptr' could be removed.	2 years ago

This happens as follows. We start the exec and set an 8-byte hardware watchpoint on data.u.size8twice[1] at address 0x440048: ... (gdb) p sizeof (data.u.size8twice[1]) $1 = 8 (gdb) p &data.u.size8twice[1] $2 = (uint64_t ) 0x440048 <data+16> ... We continue execution, and a 16-byte write at address 0x440040 triggers the hardware watchpoint: ... 4101c8: a9000801 stp x1, x2, [x0] ... When checking whether a watchpoint has triggered in aarch64_stopped_data_address, we check against address 0x440040 (passed in parameter addr_trap). This behaviour is documented: ... / ADDR_TRAP reports the first address of the memory range accessed by the CPU, regardless of what was the memory range watched. ... */ ... and consequently the matching logic compares against an addr_watch_aligned: ... && addr_trap >= addr_watch_aligned && addr_trap < addr_watch + len) ... However, the comparison fails: ... (gdb) p /x addr_watch_aligned $3 = 0x440048 (gdb) p addr_trap >= addr_watch_aligned $4 = false ... Consequently, aarch64_stopped_data_address returns false, and stopped_by_watchpoint returns false, and watchpoints_triggered returns 0, which make infrun think it's looking at a delayed hardware breakpoint/watchpoint trap: ... [infrun] handle_signal_stop: stop_pc=0x4101c8 [infrun] handle_signal_stop: delayed hardware breakpoint/watchpoint trap, ignoring ... Infrun then ignores the trap and continues, but runs into the same situation again and again, causing a hang which then causes the test timeout. Fix this by allowing a match 8 bytes below addr_watch_aligned. This introduces the possibility for false positives, so we only do this for regular "value changed" watchpoints. An earlier version of this patch worked by aligning addr_watch_aligned to 16 instead of 8: ... - const CORE_ADDR addr_watch_aligned = align_down (state->dr_addr_wp[i], 8); + const CORE_ADDR addr_watch_aligned = align_down (state->dr_addr_wp[i], 16); ... but while that fixed the test-case, it didn't fix the problem completely, so extend the test-case to check more scenarios.

(gdb) continue^M Continuing.^M ^M Hardware watchpoint 2: -location q.a^M ^M Old value = 1^M New value = 0^M main () at watch-bitfields.c:42^M 42 q.h--;^M (gdb) FAIL: $exp: -location watch against bitfields: q.e: 0->5: continue ...

However, if we set in addition a watchpoint on q.a, the watchpoint on q.e doesn't trigger. How does this happen? Bitfield q.a is just bit 0 of byte 0, and bitfield q.e is bit 4..7 of byte 1 and bit 1 of byte 2. So, watch q.a should watch byte 0, and watch q.e should watch bytes 1 and 2. Using "maint set show-debug-regs on" (and some more detailed debug prints) we get: ... WP2: addr=0x440028 (orig=0x440029), ctrl=0x000000d5, ref.count=1 ctrl: enabled=1, offset=1, len=2 WP3: addr=0x440028 (orig=0x440028), ctrl=0x00000035, ref.count=1 ctrl: enabled=1, offset=0, len=1 ... which matches that. When executing line 37, a hardware watchpoint trap triggers and we hit aarch64_stopped_data_address with addr_trap == 0x440028: ... (gdb) p /x addr_trap $1 = 0x440028 .... and since the loop in aarch64_stopped_data_address walks backward, we check WP3 first, which matches, and consequently target_stopped_by_watchpoint returns true in watchpoints_triggered. Likewise for target_stopped_data_address, which also returns addr == 0x440028. Watchpoints_triggered matches watchpoint q.a to that address, and sets watch_triggered_yes. However, subsequently the value of q.a is checked, and it's the same value as before (becase the insn in line 37 didn't change q.a), so the watchpoint hardware trap is not reported to the user. The problem originates from that fact that aarch64_stopped_data_address picked WP3 instead of WP2. There's something we can do about this. In the example above, both target_stopped_by_watchpoint and target_stopped_data_address returned true. Instead we can return true in target_stopped_by_watchpoint but false in target_stopped_data_address. This lets watchpoints_triggered known that a watchpoint was triggered, but we don't know where, and both watchpoints get set to watch_triggered_unknown. Subsequently, the values of both q.a and q.e are checked, and since q.e is not the same value as before, the watchpoint hardware trap is reported to the user. Note that this works well for regular (write) watchpoints (watch command), but not for read watchpoints (rwatch command), because for those no value is checked. Likewise for access watchpoints (awatch command). So, fix this by: - passing a nullptr in aarch64_fbsd_nat_target::stopped_by_watchpoint and aarch64_linux_nat_target::stopped_by_watchpoint to make clear we're not interested in the stop address, - introducing a two-phase approach in aarch64_stopped_data_address, where: - phase one handles access and read watchpoints, as before, and - phase two handles write watchpoints, where multiple matches cause: - return true if addr_p == null, and - return false if addr_p != null.

This patch removes tui-out.[ch] and changes the TUI to use an ordinary cli-out object without this flag set. As far as I can tell, this doesn't affect behavior at all -- the TUI tests all pass, and interactively I tried switching stack frames, "list", etc, and it all seems to work. New in v2: fixed the problem pointed out by Keith, and added a test case for that scenario. Reviewed-By: Andrew Burgess <aburgess@redhat.com>	2 years ago
Simon Marchi	0824937af0	gdb/Makefile.in: remove ACLOCAL_AMFLAGS aclocal picks up the relevant include paths from AC_CONFIG_MACRO_DIRS in configure.ac, so there's no need to pass `-I ../config` here. Passing `-I ../config` is actually annoying, because it makes the output different between when the update is triggered by the maintainer mode and when aclocal or autoreconf is ran with no special flags. The difference in the output is due to the order of include paths being different. Change-Id: I2c963876516570842f20b4a6a470867e7a941006 Approved-By: Tom Tromey <tom@tromey.com>	2 years ago
Tom Tromey	3a3f1548fa	Special case NULL pointers in dynamic type resolution commit `f18fc7e5` ("gdb, types: Resolve pointer types dynamically") caused a regression on a test case in the AdaCore internal test suite. The issue here is that gdb would try to resolve the type of a dynamic pointer that happened to be NULL. In this case, the "Location address is not set." error would end up being thrown from the DWARF expression evaluator. I think it makes more sense to special-case NULL pointers and not try to resolve their target type, as that type can't really be accessed anyway. This patch implements this idea, and also adds the missing Ada test case.	2 years ago
Andrew Burgess	1320cb92da	gdb/testsuite: reformat file with a more recent version of black A Python file in my previous commit (`5eb2254a1d`) was formatted with an older version of black, which gives slightly different results. Reformat with a newer version of black. This should make our post-commit testing happy again. No functional changes in this commit.	2 years ago
Nick Alcock	9b9e262994	libctf: fix uninitialized variables in testsuite Just because a path is an error path doesn't mean the program terminates there if you don't ask it to. And we don't want to -- but that means we need to initialize the variables that are missed if an error happens to something. Type ID 0 (unimplemented) will do: it'll induce further ECTF_BADID errors, but that's no bad thing. libctf/ChangeLog: * testsuite/libctf-writable/libctf-errors.c: Initialize variables.	2 years ago
Simon Marchi	02b2f39703	gdb: re-generate aclocal.m4 I get some changes when running `autoreconf -vf` in the gdb directory, fix that. I did a bisect, it appears to have been introduced in this commit, not sure why we haven't spotted that before. commit `862776f26a` Author: Arsen Arsenovi? <arsen@aarsen.me> AuthorDate: Wed Nov 15 12:53:04 2023 +0000 Commit: Nick Clifton <nickc@redhat.com> CommitDate: Wed Nov 15 12:53:04 2023 +0000 Change-Id: I798d2fbff40c39dbc899832c64e72b2859b536b9	2 years ago
Markus Metzger	b792eb47f2	gdb, btrace: fix error diagnostics When we improved error messages in `cd393cec3a` gdb, btrace: improve error messages we cleared the original errno. When the error reason can not be explained in a more detailed error message, and we fall back to the default error message, it now gives Success as error. Restore the original errno to fix that.	4 years ago
