2020-01-15Reinstate gas em=freebsd for sparc-freebsdAlan Modra2-0/+5
In commit c9098af41e3 I over-simplified the sparc target decoding, missing the fact that prior to that patch sparc-*-freebsd fell through to the generic *-*-freebsd match. * configure.tgt: Add sparc-*-freebsd case.
2020-01-15PR25384, PowerPC64 ELFv1 copy relocs against function symbolsAlan Modra7-27/+58
Function symbols of course don't normally want .dynbss copies but with some old versions of gcc they are needed to copy the function descriptor. This patch restricts the cases where they are useful to compilers using dot-symbols, and enables the warning regardless of whether a PLT entry is emitted in the executable. PLTs in shared libraries are affected by a .dynbss copy in the executable. bfd/ PR 25384 * elf64-ppc.c (ELIMINATE_COPY_RELOCS): Update comment.

2020-01-14Fix valgrind error from gdb.decode_lineTom Tromey4-0/+25
PR symtab/12535 points out that gdb.decode_line("") will cause a valgrind report. I think the empty linespec does not really make sense. So, this patch changes gdb.decode_line to treat a whitespace-only linespec the same as a non-existing argument. gdb/ChangeLog 2020-01-14 Tom Tromey <tom@tromey.com> PR symtab/12535: * python/python.c (gdbpy_decode_line): Treat empty string the same as no argument. gdb/testsuite/ChangeLog 2020-01-14 Tom Tromey <tom@tromey.com> PR symtab/12535: * gdb.python/python.exp: Test decode_line with empty string argument.

2020-01-14Move many configure checks to common.m4Tom Tromey16-1980/+5360
This moves many needed configure checks from gdb and gdbserver into common.m4. This helps gdbsupport, nat, and target be self-contained. The result is a bit spaghetti-ish, because gdbsupport uses another m4 file from gdb/. The resulting code is somewhat non-obvious. However, these problems already exist, so it's not really that much worse than what is already done. gdb/ChangeLog 2020-01-14 Tom Tromey <tom@tromey.com> * configure: Rebuild. * configure.ac: Move many checks to ../gdbsupport/common.m4. gdb/gdbserver/ChangeLog 2020-01-14 Tom Tromey <tom@tromey.com> * configure: Rebuild. * configure.ac: Remove any checks that were added to common.m4. * acinclude.m4: Include lib-ld.m4, lib-prefix.m4, and lib-link.m4. gdbsupport/ChangeLog 2020-01-14 Tom Tromey <tom@tromey.com> * configure, Makefile.in, aclocal.m4, common.m4, config.in: Rebuild. * common.m4 (GDB_AC_COMMON): Move many checks from gdb/configure.ac. * acinclude.m4: Include bfd.m4, ptrace.m4.

2020-01-14Move gdbsupport to the top levelTom Tromey146-141/+13387
This patch moves the gdbsupport directory to the top level. This is the next step in the ongoing project to move gdbserver to the top level. The bulk of this patch was created by "git mv gdb/gdbsupport gdbsupport". This patch then adds a build system to gdbsupport and wires it into the top level. Then it changes gdb to use the top-level build. gdbserver, on the other hand, is not yet changed. It still does its own build of gdbsupport.

2020-01-13gdb: Handle malformed ELF, symbols in non-allocatable sectionsAndrew Burgess6-4/+253
I ended up debugging a malformed ELF where a section containing executable code was not correctly marked as allocatable. Before realising the ELF was corrupted I tried to place a breakpoint on a symbol in the non-allocatable, executable section, and GDB crashed. Though trying to debug such an ELF clearly isn't going to go well I would prefer, as far as possible, that any input, no matter how corrupted, not crash GDB. The crash occurs when trying to set a breakpoint on the name of a function from the corrupted section. GDB converts the symbol to a symtab_and_line, and looks up a suitable section for this. The problem is that the section is actually an obj_section, which is stored in the table within the objfile, and we only initialise this table for allocatable sections (see add_to_objfile_sections_full in objfiles.c). So, if the symbol is in a non-allocatable section then we end up referencing an uninitialised obj_section. Later we call get_sal_arch on the symtab_and_line, which calls get_objfile_arch, which uses the objfile from the uninitialised obj_section, which will be nullptr, at which point GDB crashes. The fix I propose here is that when we setup the section references on msymbols, we should check if the bfd_section being referenced is allocatable or not. If it is not then we should set the section reference back to the default 0 section (see how MSYMBOL_OBJ_SECTION and SYMBOL_OBJ_SECTION treat the 0 section index). With this fix in place GDB no longer crashes. Instead GDB creates the breakpoint at the non-allocated address, and then fails, with an error, when it tries to insert the breakpoint. gdb/ChangeLog: * elfread.c (record_minimal_symbol): Set section index to 0 for non-allocatable sections. gdb/testsuite/ChangeLog: * gdb.dwarf2/dw2-bad-elf-other.S: New file. * gdb.dwarf2/dw2-bad-elf.c: New file. * gdb.dwarf2/dw2-bad-elf.exp: New file.

2020-01-13gdb/testsuite: Allow DWARF assembler to create multiple line tablesAndrew Burgess2-0/+7
Fixes a bug in the DWARF assembler that prevents multiple line tables from being created in a test. We currently don't initialise a couple of flags, as a result we will only ever generate one end of file list, and one end of header, in the first line table. Any additional line tables will be missing these parts, and will therefore be corrupt. This fix will be required for a later commit. There should be no change in the testsuite after this commit. gdb/testsuite/ChangeLog: * lib/dwarf.exp (Dwarf::lines): Reset _line_saw_program and _line_saw_file.

2020-01-13Dwarf 5: Handle debug_str_offsets and indexed attributes that have base offsets.Ali Tamur5-92/+282
* Process debug_str_offsets section. Handle DW_AT_str_offsets_base attribute and keep the value in dwarf2_cu. * Make addr_base field in dwarf2_cu optional to disambiguate 0 value (absent or present and 0). * During parsing, there is no guarantee that DW_AT_str_offsets_base and DW_AT_rnglists_base fields will be processed before the attributes that need those values for correct computation. So make two passes, on the first one mark the attributes that depend on *_base attributes and process only the others. On the second pass, only process the attributes that are marked on the first pass. * For string attributes, differentiate between addresses that directly point to a string and those that point to an offset in debug_str_offsets section. * There are now two attributes, DW_AT_addr_base and DW_AT_GNU_addr_base to read address offset base. Likewise, there are two attributes, DW_AT_rnglists_base and DW_AT_GNU_ranges_base to read ranges base. Since there is no guarantee which ones the compiler will generate, create helper functions to handle all cases. Tested with CC=/usr/bin/gcc (version 8.3.0) against master branch (also with -gsplit-dwarf and -gdwarf-4 flags) and there was no increase in the set of tests that fails. (gdb still cannot debug a 'hello world' program with DWARF 5, so for the time being, this is all we care about). This is part of an effort to support DWARF-5 in gdb.

2020-01-13gdbserver: set IP_AGENT_EXPORT_FUNC to static when not building IPA, add ↵Simon Marchi3-1/+29
declarations Fixing the -Wmissing-declarations errors in gdbserver's tracepoint.c is a bit tricky, because some functions are compiled for both gdbserver, in which case they should be static, since they are only used in that file, and for libinproctrace.so, in which case they should be externally visible, since they need to be looked up. In the case where they are externally visible, -Wmissing-declarations requires that a declaration exists (that's the point of the warning). I've reused the IP_AGENT_EXPORT_FUNC macro to mark the functions as static when compiled for gdbserver.

2020-01-13gdb: add declaration to Python init functionSimon Marchi2-0/+5
When I try to enable -Wmissing-declarations, I get this error: CXX python/python.o /home/smarchi/src/binutils-gdb/gdb/python/python.c: In function ‘PyObject* init__gdb_module()’: /home/smarchi/src/binutils-gdb/gdb/python/python.c:1582:1: error: no previous declaration for ‘PyObject* init__gdb_module()’ [-Werror=missing-declarations] init__gdb_module (void) ^~~~~~~~~~~~~~~~ Prevent it by providing a declaration just before the definition. gdb/ChangeLog: * python/python.c (init__gdb_module): Add declaration.

2020-01-13gdb: add back declarations for _initialize functionsSimon Marchi400-354/+1167
I'd like to enable the -Wmissing-declarations warning. However, it warns for every _initialize function, for example: CXX dcache.o /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’: /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations] _initialize_dcache (void) ^~~~~~~~~~~~~~~~~~ The only practical way forward I found is to add back the declarations, which were removed by this commit: commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9 Author: John Baldwin <jhb@FreeBSD.org> Date: Sat Sep 9 11:02:37 2017 -0700 Remove unnecessary function prototypes. I don't think it's a big problem to have the declarations for these functions, but if anybody has a better solution for this, I'll be happy to use it. gdb/ChangeLog: * aarch64-fbsd-nat.c

2020-01-13gdb: make regformats output a declaration for the init functionSimon Marchi2-0/+8
When compiling gdbserver for an architecture that uses the regdat.sh script (such as m68k) and the -Wmissing-declarations compiler flag, I get: REGDAT reg-m68k-generated.c CXX reg-m68k.o reg-m68k-generated.c:30:1: error: no previous declaration for 'void init_registers_m68k()' [-Werror=missing-declarations] 30 | init_registers_m68k (void) | ^~~~~~~~~~~~~~~~~~~ The same happens with other architectures, such as s390, but I'll be using 68k as an example. The init_registers_m68k function is defined in reg-m68k-generated.c, which is produced by the regformats/regdat.sh script. This script reads the regformats/reg-m68k.dat file, containing a register description, and produces C code that creates a corresponding target description at runtime. The init_registers_m68k function is invoked at initialization time in linux-m68k-low.c. The function must therefore be non-static, but does not have a declaration at the moment. The real clean way of fixing this would be to make regdat.sh generate a .h file (in addition to the .c file) with declarations for whatever is in the .c file. The generated .c file would include the .h file, and therefore the definition would have a corresponding declaration. The linux-m68k-low.c file would also include this .h file, instead of having its own declaration of init_registers_m68k, like it does now. However, this would be a quite big change for not much gain. As far as I understand, some common architectures (i386, x86-64, ARM, AArch64) have been moved to dynamically building target descriptions based on features (the linux-*-tdesc.c files in gdbserver) and don't use regdat.sh anymore. Logically (and given infinite development resources), the other architectures would be migrated to this system too and the regdat.sh script would be dropped. A new architecture would probably not use regdat.sh either. So I therefore propose this simpler patch instead, which just adds a local declaration in the generated file. gdb/ChangeLog: * regformats/regdat.sh: Generate declaration for init function.
2020-01-13gdbserver: fix Makefile dependency of regformat-generated files on regdat.shSimon Marchi2-4/+9
The intent of the rules modified by this patch is that the *-generated.c files generated by regdat.sh are re-generated in the event that regdat.sh is modified. However, if I build, touch regdat.sh, and build again, the files are not re-generated during the second build. This is because regdat.sh is specified as an order-only dependency [1], after the pipe. Make therefore only ensures that regdat.sh exists before generating the target file, it doesn't check the timestamp of regdat.sh. This patch changes it to be a regular prerequisite. The rules use the $< variable, which is substituted by the first prerequisite only, so the command lines won't change. [1] https://www.gnu.org/software/make/manual/html_node/Prerequisite-Types.html gdb/gdbserver/ChangeLog: * Makefile.in (%-generated.c): Make $(regdat_sh) a regular prerequisite.

2020-01-13gdb: adjust remote-sim.c to multi-targetSimon Marchi2-78/+91
The remote-sim.c file doesn't build since the main multi-target patch (5b6d1e4f, "Multi-target support"), this patch is an attempt to fix it. I have only build-tested it, so I'm not sure it runs fine, but it should get us close at least. I made these functions methods of the gdbsim_target, because they need to pass the target down to some GDB core functions, like find_inferior_ptid: - get_sim_inferior_data_by_ptid (renamed to get_inferior_data_by_ptid) - gdbsim_resume_inferior (renamed to resume_one_inferior) - gdbsim_close_inferior (renamed to close_one_inferior) In the last two, I changed iterate_over_inferiors to a range-based for, since that gives simpler code (no need to pass data through the void pointer). The next_pid variable, INITIAL_PID macro and sim_inferior_data structure are simply moved up in the file, above gdbsim_target. gdb/ChangeLog: * remote-sim.c (next_pid, INITIAL_PID, sim_inferior_data): Move up. (gdbsim_target) <get_inferior_data_by_ptid, resume_one_inferior, close_one_inferior>: New methods. (get_sim_inferior_data_by_ptid): Move to gdbsim_target, pass down target to find_inferior_pid. (gdbsim_target::fetch_registers, gdbsim_target::store_registers): Pass down target to find_inferior_ptid. (gdbsim_target::create_inferior): Pass down target to add_thread_silent. (gdbsim_close_inferior): Move to gdbsim_close_inferior, pass target down to find_inferior_ptid and switch_to_thread. (gdbsim_target::close): Update to call close_one_inferior. (struct resume_data): Remove. (gdbsim_resume_inferior): Move to gdbsim_target. Take arguments directly, rather than through a void pointer. (gdbsim_target::resume): Update to call resume_one_inferior.
