2019-04-13gdb: Fix failure in gdb.base/complex-parts.exp for x86-32Andrew Burgess2-0/+16
The x86-32 ABI specifies 96-bit long double, this was causing a failure on the test gdb.base/complex-parts.exp. The problem is that GDB tries to find a builtin floating point type of the correct size in order to reuse the name of that type as the name for the components of the complex type being built. Previously GDB was only aware of floating point types sized 32, 64, or 128 bits. This patch teaches GDB how to handle 96 bit floating point type. gdb/ChangeLog: * dwarf2read.c (dwarf2_init_complex_target_type): Handle complex target types of size 96-bits, add some additional comments, and check that the builtin type we found was the correct size.
2019-04-12Another fix for GDB stylingEli Zaretskii2-4/+7
gdb/ChangeLog: 2019-04-12 Eli Zaretskii <eliz@gnu.org> * utils.c (prompt_for_continue): Don't restore the styling at the end, as applied_style has the wrong value. This fixes styling in long lists of file names that are interrupted by the "Continue?" prompt.
2019-04-12Testsuite: Add gdbserver sysroot testAlan Hayward4-7/+118
The local board file ensures that the sysroot is always set to load files from the local filesystem. Add a gdbserver test to explicitly test the sysroot set to both the remote target and the local filesystem. gdb/testsuite/ChangeLog: * gdb.server/sysroot.c: New test. * gdb.server/sysroot.exp: New file. * lib/gdbserver-support.exp (gdb_target_cmd): Add additional text matching param.
2019-04-12gdb: Remove LANG_MAGICAndrew Burgess13-38/+35
The language_defn structure has an la_magic field, this used to be used as a basic check that the language_defn structure had the expected layout - at least the end of the structure was where we expected it to be. This feature only really makes sense if we imagine GDB dynamically loading language support from dynamic libraries, where a version mismatch might cause problems. However, in current GDB language support is statically built into GDB, and since this commit: commit 47e77640be31fc1a4eb3718f594ed5fd0faff065 Date: Thu Jul 20 18:28:01 2017 +0100 Make language_def O(1) the existing (if pointless) check of the la_magic field was removed. There now appears to be no use of the la_magic field, and I propose that we delete it. There should be no user visible changes after this commit. gdb/ChangeLog: * ada-lang.c (ada_language_defn): Remove use of LANG_MAGIC. * c-lang.c (c_language_defn): Likewise. (cplus_language_defn): Likewise. (asm_language_defn): Likewise. (minimal_language_defn): Likewise. * d-lang.c (d_language_defn): Likewise. * f-lang.c (f_language_defn): Likewise. * go-lang.c (go_language_defn): Likewise. * language.c (unknown_language_defn): Likewise.

2019-04-11gdb/riscv: Remove riscv_type_alignment functionAndrew Burgess2-48/+19
Make use of the type_align function and remove riscv_type_alignment as it is no longer needed. I tested this against a number of RV32 and RV64 targets, and I also ran the tests with an assertion in place checking that the old riscv_type_alignment function gives the same answer as the common type_align function - it does, and all the tests still pass. gdb/ChangeLog: * riscv-tdep.c (riscv_type_align): New function. (riscv_type_alignment): Delete. (riscv_arg_location): Use 'type_align'. (riscv_gdbarch_init): Register riscv_type_align gdbarch function.
2019-04-11gdb: Fix alignment computation for structs with only static fieldsAndrew Burgess4-12/+34
The current code in gdbtypes.c:type_align incorrectly returns 0 as the alignment for a structure containing only static fields. After this patch the correct value of 1 is returned. The gdb.base/align.exp test is extended to cover this case. gdb/ChangeLog: * gdbtypes.c (type_align): A struct with no non-static fields also has alignment of 1. gdb/testsuite/ChangeLog: * gdb.base/align.exp: Extend test to cover structures containing only static fields.
2019-04-11gdb/riscv: Handle empty C++ structs during argument passingAndrew Burgess2-43/+132
This commit resolves a large number of failures in the test script gdb.base/infcall-nested-structs.exp which were caused by GDB (for RISC-V) incorrectly handling empty C++ structures when preparing arguments for a dummy call, or collecting a return value. The issue is further complicated in that there was a bug in GCC, such that in some cases GCC would generate incorrect code when passing a small structure that contained empty sub-structures. This was fixed in GCC trunk on 5-March-2019, so in order to see the best results with this patch you'll need a recent version of GCC. Anything that used to work should continue to work after this patch, regardless of GCC version being used. The fix in this commit is that GDB now pays more attention to the offset of fields within a structure when preparing arguments as in C++ an empty structure has a non-zero size, this is an example: struct s1 { struct s2 { } empty; int f; }; We previously assumed that 'f' was at offset 0 inside type 's1', however this is not the case in C++ as 's2' has size 1, and with alignment 'f' is likely at some even bigger offset inside 's1'. gdb/ChangeLog: * riscv-tdep.c (riscv_call_arg_complex_float): Fix offset of first component to 0. (riscv_struct_info::riscv_struct_info): Initialise m_offsets member. (riscv_struct_info::analyse): New implementation using new analyse_inner member function. (riscv_struct_info::field_offset): New member function. (riscv_struct_info::m_offsets): New member variable. (riscv_struct_info::analyse_inner): New private member function, takes the old implementation of riscv_struct_info::analyse but extended to track field offsets. (riscv_call_arg_struct): Update the struct folding special cases to handle cases where empty C++ structs, which are non-zero length, are found. (riscv_arg_location): Initialise the length of each location, a non-zero length now indicates the location is in use. (riscv_push_dummy_call): Allow for the first location having a non-zero offset when setting up arguments. (riscv_return_value): Likewise, but for return values.
2019-04-11Make "msg" const in internal_vproblemTom Tromey2-1/+5
I noticed that the "msg" variable in internal_vproblem could be "const". This seems like an improvement because it can wind up in rodata. Tested by rebuilding. gdb/ChangeLog 2019-04-11 Tom Tromey <tromey@adacore.com> * utils.c (internal_vproblem): Make "msg" const.
2019-04-11[gdb/testsuite] Add cc-with-dwz.exp and cc-with-dwz-m.expTom de Vries4-0/+66
We can use CC_WITH_TWEAKS_FLAGS when cd-ing into the gdb build subdir and invoking make check: ... $ cd $objdir/gdb $ make check \ RUNTESTFLAGS='--target_board=cc-with-tweaks' \ CC_WITH_TWEAKS_FLAGS='-z' ... But when cd-ing into the top-level build dir and invoking make check-gdb instead: ... $ cd $objdir $ make check-gdb \ RUNTESTFLAGS='--target_board=cc-with-tweaks' \ CC_WITH_TWEAKS_FLAGS='-z' ... using CC_WITH_TWEAKS_FLAGS has no effect, because CC_WITH_TWEAKS_FLAGS is not passed down from the top level Makefile. Add cc-with-dwz.exp and cc-with-dwz-m.exp, that don't require CC_WITH_TWEAKS_FLAGS to be set in the make invocation, allowing us to run these test configurations from the toplevel build dir: ... $ cd $objdir $ make check-gdb \ RUNTESTFLAGS='--target_board=cc-with-dwz' ... Tested on x86_64-linux. gdb/testsuite/ChangeLog: 2019-04-11 Tom de Vries <tdevries@suse.de> * boards/cc-with-dwz-m.exp: New file. * boards/cc-with-dwz.exp: New file. * boards/cc-with-tweaks.exp: Note that check-gdb doesn't work.
2019-04-11AArch64: Ensure regcache is reset between testsAlan Hayward4-6/+27
A recent change made the AArch64 self tests resuse the saved regs cache, rather than creating a new one. Ensure it is reset to default values between tests. Do this by splitting the reset functionality from trad_frame_alloc_saved_regs into a new function. Fixes selftest on AArch64. gdb/ChangeLog: * aarch64-tdep.c (aarch64_analyze_prologue_test): Reset saved regs. * trad-frame.c (trad_frame_reset_saved_regs): New function. (trad_frame_alloc_saved_regs): Call trad_frame_reset_saved_regs. * trad-frame.h (trad_frame_reset_saved_regs): New declaration.
2019-04-10Fix amd64->i386 linux syscall restart problemKevin Buettner4-2/+93
This commit fixes some failures in gdb.base/interrupt.exp when debugging a 32-bit i386 linux inferior from an amd64 host. When running the following test... make check RUNTESTFLAGS="--target_board unix/-m32 interrupt.exp" ... without this commit, I see the following output: FAIL: gdb.base/interrupt.exp: continue (the program exited) FAIL: gdb.base/interrupt.exp: echo data FAIL: gdb.base/interrupt.exp: Send Control-C, second time FAIL: gdb.base/interrupt.exp: signal SIGINT (the program is no longer running) ERROR: Undefined command "". ERROR: GDB process no longer exists === gdb Summary === When the test is run with this commit in place, we see 12 passes instead. This is the desired behavior. Analysis: On Linux, when a syscall is interrupted by a signal, the syscall may return -ERESTARTSYS when a signal occurs. Doing so indicates that the syscall is restartable. Then, depending on settings associated with the signal handler, and after the signal handler is called, the kernel can then either return -EINTR or can cause the syscall to be restarted. In this discussion, we are concerned with the latter case. On i386, the kernel returns this status via the EAX register. When debugging a 32-bit (i386) process from a 64-bit (amd64) GDB, the debugger fetches 64-bit registers even though the process being debugged is 32-bit. Since we're debugging a 32-bit target, only 32 bits are being saved in the register cache. Now, ideally, GDB would save all 64-bits in the regcache and then would be able to restore those same values when it comes time to continue the target. I've looked into doing this, but it's not easy and I don't see many benefits to doing so. One benefit, however, would be that EAX would appear as a negative value for doing syscall restarts. At the moment, GDB is setting the high 32 bits of RAX (and other registers too) to 0. So, when GDB restores EAX just prior to a syscall restart, the high 32 bits of RAX are zeroed, thus making it look like a positive value. For this particular purpose, we need to sign extend EAX so that RAX will appear as a negative value when EAX is set to -ERESTARTSYS. This in turn will cause the signal handling code in the kernel to recognize -ERESTARTSYS which will in turn cause the syscall to be restarted. This commit is based on work by Jan Kratochvil from 2009: https://sourceware.org/ml/gdb-patches/2009-11/msg00592.html Jan's patch had the sign extension code in amd64-nat.c. Several other native targets make use of this code, so it seemed better to move the sign extension code to a linux specific file. I also added similar code to gdbserver. Another approach is to fix the problem in the kernel. Hui Zhu tried to get a fix into the kernel back in 2014, but it was not accepted. Discussion regarding this approach may be found here: https://lore.kernel.org/patchwork/patch/457841/ Even if a fix were to be put into the kernel, we'd still need some kind of fix in GDB in order to support older kernels. Finally, I'll note that Fedora has been carrying a similar patch for at least nine years. Other distributions, including RHEL and CentOS have picked up this change and have been using it too. gdb/ChangeLog: * amd64-linux-nat.c (amd64_linux_collect_native_gregset): New function. (fill_gregset): Call amd64_linux_collect_native_gregset instead of amd64_collect_native_gregset. (amd64_linux_nat_target::store_registers): Likewise. gdb/gdbserver/ChangeLog: * linux-x86-low.c (x86_fill_gregset): Sign extend EAX value when using a 64-bit gdbserver.
2019-04-10Introduce a separate debug objfile iteratorTom Tromey5-54/+121
This introduces a new iterator and range adapter for iteration over the separate debug files of a given objfile. As in the current approach, the requested objfile is returned first, followed by the separate debug objfiles. gdb/ChangeLog 2019-04-10 Tom Tromey <tom@tromey.com> * symtab.c (lookup_global_symbol_from_objfile) (lookup_symbol_in_objfile_from_linkage_name): Use the iterator. * objfiles.h (class separate_debug_iterator): New. (class separate_debug_range): New. (struct objfile) <separate_debug_objfiles>: New method. (objfile_separate_debug_iterate): Don't declare. * objfiles.c (separate_debug_iterator::operator++): Rename from objfile_separate_debug_iterate. (objfile_relocate, objfile_rebase, objfile_has_symbols): Use the iterator. * minsyms.c (lookup_minimal_symbol_by_pc_section): Use the iterator.
2019-04-10Fix a couple of commentsTom Tromey3-7/+6
While working on objfiles I noticed a typo in one comment, and another comment that, as far as I can tell, has been obsolete for a very long time. gdb/ChangeLog 2019-04-10 Tom Tromey <tom@tromey.com> * symfile.c (reread_symbols): Remove old comment. * objfiles.c (free_all_objfiles): Fix a typo.
2019-04-10Remove some uses of "object_files"Tom Tromey4-20/+20
The "object_files" macro is sometimes used when iterating over objfiles. This patch removes a few such uses in favor of the new range adapter. gdb/ChangeLog 2019-04-10 Tom Tromey <tom@tromey.com> * ia64-tdep.c (ia64_get_dyn_info_list): Use foreach. * minsyms.c (lookup_minimal_symbol): Use foreach.

2019-04-09Fix Rust lexer bugletTom Tromey2-2/+12
PR rust/24414 points out that the Rust lexer uses strtoul when lexing an integer, and that this can give the wrong results in some situations. This patch changes it to use strtoulst, like most of the rest of gdb. It also adds a self test. Tested on x86-64 Fedora 29 using an i686 build. gdb/ChangeLog 2019-04-09 Ivan Begert <ivanbegert@gmail.com> Tom Tromey <tromey@adacore.com> PR rust/24414: * rust-exp.y (rust_parser::lex_number): Use strtoulst. (rust_lex_int_test): Change "value" to be LONGEST. (rust_lex_tests): Add test for long integer literal.
2019-04-09Use find_thread_in_random in select_event_lwpTom Tromey2-31/+8
I noticed that find_thread_in_random duplicates the code in find_thread_in_random, so this patch changes the latter to use the former. There are two other spots in gdb that do this, but to unify all of them would require switching some code from using the "iterate over" idiom to using iterators. Another possible improvement is that find_thread_in_random could be made single-pass using reservoir sampling. Tested by the buildbot. gdb/gdbserver/ChangeLog 2019-04-09 Tom Tromey <tromey@adacore.com> * linux-low.c (select_event_lwp): Use find_thread_in_random.
2019-04-09Consistently use bool for fake_pid_pTom Tromey4-10/+20
I noticed a few spots where fake_pid_p is handled as an int, whereas the field in struct inferior has type bool. This patch changes the remaining places to use bool as well. Tested by the buildbot. gdb/ChangeLog 2019-04-09 Tom Tromey <tromey@adacore.com> * remote.c (remote_target::remote_add_inferior): Change fake_pid_p to bool. (extended_remote_target::attach): Update. (remote_target::remote_notice_new_inferior): Update.

2019-04-09Use -qualified flag when setting temporary breakpoint in start commandSimon Marchi5-1/+84
When using the "start" command, GDB puts a temporary breakpoint on the "main" symbol (we literally invoke the tbreak command). However, since it does wild matching by default, it also puts a breakpoint on any C++ method or "main" function in a namespace. For example, when debugging GDB, it creates a total of 24 locations: (gdb) start Temporary breakpoint 1 at 0x198c1e9: main. (24 locations) as there are a bunch of methods called main in the selftests, such as selftests::string_view::capacity_1::main() If such method was called in the constructor of a global object, or a function marked with the attribute "constructor", then we would stop at the wrong place. Also, this causes a few extra symtabs (those that contain the "wrong" mains) to be expanded for nothing. The dummiest, most straightforward solution is to add -qualified when invoking tbreak. With this patch, "start" creates a single-location breakpoint, as expected. I copied the start.exp test to start-cpp.exp and made it use a C++ test file, which contains two main functions. The new test verifies that the output of "start" is the output we get when we set a single-location breakpoint. gdb/ChangeLog: * infcmd.c (run_command_1): Pass -qualified to tbreak when usind the "start" command. gdb/testsuite/ChangeLog: * gdb.base/start-cpp.exp: New file. * gdb.base/start-cpp.cc: New file.
2019-04-08Rename python function thread_from_thread_handle to thread_from_handleKevin Buettner6-20/+50
This renaming was done to stay consistent with the naming of the new gdb.InferiorThread.handle method. I had initially named it "thread_handle" but Tom Tromey suggested just "handle". The old name (thread_from_thread_handle) still works, but is marked as deprecated in comments in the code as well as in the documentation. I have some code which uses these functions. I very much like the brevity of the new names. gdb/doc/ChangeLog: * python.texi (Inferiors In Python): Rename Inferior.thread_from_thread_handle to Inferior.thread_from_handle. Add note about the former being deprecated. gdb/ChangeLog: * python/py-inferior.c (infpy_thread_from_thread_handle): Adjust comments to reflect renaming of thread_from_thread_handle to thread_from_handle. Adjust keywords. Fix type error message. (inferior_object_methods): Add thread_from_handle. Retain thread_from_thread_handle, but mark it as deprecated. testsuite/ChangeLog: * gdb.python/py-thrhandle.exp: Adjust tests to call thread_from_handle instead of thread_from_thread_handle.

2019-04-08Support buffer objects as handles in Inferior.thread_from_thread_handle()Kevin Buettner4-10/+37
InferiorThread.handle() returns a python bytes object. We'd like to be able to pass the output of this function, a thread handle, to Inferior.thread_from_thread_handle(). Up to now, thread_from_thread_handle() expects to receive a gdb.Value input. This commit adds support to also allow a python buffer object to be passed as the handle. infpy_thread_from_thread_handle() calls find_thread_by_handle() which has the obvious functionality. It used to pass the thread handle via a struct value pointer. I've revised this interface to instead pass a gdb::array_view<const gdb_byte> object. (Thanks to Tom Tromey for suggesting this data structure over an earlier version which passed a gdb_byte pointer and length.) gdb/ChangeLog: * gdbthread.h (find_thread_by_handle): Revise declaration. * thread.c (find_thread_by_handle): Likewise. Adjust implementation too. * python/py-inferior.c (infpy_thread_from_thread_handle): Add support for buffer objects as handles.

2019-04-08Some gdb_exception{,error,quit} tweaksPedro Alves3-22/+43
- Explicitly include <string> for std::string. - Use std::make_shared to construct gdb_exception::message instead of operator new, avoiding one heap allocation (2 instead of 3). Add 'const char *fmt, va_list ap' parameters to gdb_exception{,error,quit}'s ctors, and do the std::make_shared in the gdb_exception ctor. - gdb_exception_error's constructor does not need to have an 'enum return_reason' parameter, since it is always RETURN_ERROR, by definition. - Similarly, gdb_exception_quit's contructor does not need to have 'enum return_reason'/'enum errors' parameters. - In the gdb_exception_{quit,_error} ctors that take a gdb_exception as argument, assert that they're being passed a gdb_exception object of the right 'reason'. gdb/ChangeLog: 2019-04-08 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (throw_exception): Don't create named object to throw; throw directly.

2019-04-08Simplify exception handlingTom Tromey3-81/+10
Now that cleanups have been removed, TRY/CATCH can't be SJLJ-based any more. This patch simplifies the exception handling code, by removing the non-working variants. Note that the "pure" C++ exception handling code is removed as well; I think the route forward must be to change exceptions to be self-destructing, so that try_scope_depth can simply be removed. Some longjmp-based code remains, as it is needed to throw an exception through readline. gdb/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * common/common-exceptions.h (GDB_XCPT_SJMP, GDB_XCPT_TRY) (GDB_XCPT_RAW_TRY, GDB_XCPT): Remove.

2019-04-07Make "all" depend on "info"Tom Tromey2-1/+5
I've broken "make info" a couple of times now, because I sometimes forget to run "make info" after modifying a Texinfo file. I don't know why gdb's "make all" doesn't build the info pages. I suspect this was some Cygnus-local oddity back in the day. This patch changes doc/Makefile.in so that the info pages are built by "make all". As a point of reference, Automake has essentially always worked this way. According to the Automake manual (I didn't double-check) this is required by the GNU coding standards. The first time I sent this patch, I mentioned that I wanted to look into some existing bugs in bugzilla about missing "makeinfo". However, today I tried and I discovered that BFD requires makeinfo, and builds its info file as part of "all". So, I think this change doesn't worsen the situation for users in any way, and can simply go in. gdb/doc/ChangeLog 2019-04-07 Tom Tromey <tom@tromey.com> * Makefile.in (all): Depend on "info".

So, I'm reverting the patch.

2019-04-05Use linux_get_auxv to get AT_PHDR in the PPC stubPedro Franco de Carvalho4-12/+41
This patch fixes a build error due to a call to ppc_get_auxv that was left over after linux_get_hwcap and linux_get_hwcap2 were introduced in: 974c89e0882ddb03e294eca76a9e3d3bef90eacf gdbserver: Add linux_get_hwcap Because the missing call fetched AT_PHDR and not AT_HWCAP, linux_get_auxv is now visible. This use also required ppc_get_auxv to return a status variable indicating that the AT_PHDR entry was not found separately from the actual value of of the auxv entry. Therefore, the new linux_get_auxv function is changed to return a status variable and write the entry value to a pointer passed as an argument. Note that linux_get_hwcap and linux_get_hwcap2 still use the return value as both an indicator of that the entry wasn't found and as the actual value of the entry. gdb/gdbserver/ChangeLog: 2019-04-05 Pedro Franco de Carvalho <pedromfc@linux.ibm.com> * linux-low.c (linux_get_auxv): Remove static. Return auxv entry value in argument pointer, return 1 if the entry is found and 0 otherwise. Move comment. (linux_get_hwcap, linux_get_hwcap2): Use modified linux_get_auxv. * linux-low.h (linux_get_auxv): Declare. * linux-ppc-low.c (is_elfv2_inferior): Use linux_get_auxv.

2019-04-04Move innermost_block_tracker global to parse_stateTom Tromey17-97/+145
This changes the parsing API so that callers that are interested in tracking the innermost block must instantiate an innermost_block_tracker and pass it in.

2019-04-04Remove paren_depth globalTom Tromey11-14/+62
This removes the "paren_depth" global. In most cases, it is made into a static global in a given parser. I consider this a slight improvement, because it makes it clear that the variable isn't used for communication between different modules of gdb. The one exception is the Rust parser, which already incorporates all local state into a transient object; in this case the parser depth is now a member. gdb/ChangeLog 2019-04-04 Tom Tromey <tom@tromey.com> * rust-exp.y (struct rust_parser) <paren_depth>: New member.

2019-04-04Remove parser_state "initial_size" parameterTom Tromey7-13/+23
All the real (not test) uses of parser_state pass 10 as the "initial_size" parameter, and it seems to me that there's no real reason to require callers to set this. This patch removes this parameter. gdb/ChangeLog 2019-04-04 Tom Tromey <tom@tromey.com> * dtrace-probe.c (dtrace_probe::build_arg_exprs): Update. * stap-probe.c (stap_parse_argument): Update. * stap-probe.h (struct stap_parse_info) <stap_parse_info>: Remove initial_size parameter. * rust-exp.y (rust_lex_tests): Update. * parse.c (parser_state): Update. (parse_exp_in_context): Update. * parser-defs.h (struct parser_state) <parser_state>: Remove "initial_size" parameter.
