2021-09-07[gdb/testsuite] Handle internal-error in gdb_unloadTom de Vries1-0/+5
When reverting commit 5a20fadc841 and using gdb_unload instead of runto "bar" to trigger the internal-error in test-case gdb.dwarf2/locexpr-data-member-location.exp, we run into: ... ERROR: couldn't unload file in $gdb (timeout). ... and the test-case takes about 1 minute. Fix this by handling internal-error in gdb_unload, such that we have: ... ERROR: Couldn't unload file in $gdb (GDB internal error). ERROR: Could not resync from internal error (eof) ... within 2 seconds. Tested on x86_64-linux.

When reverting commit 5a20fadc841 the test-case gdb.dwarf2/locexpr-data-member-location.exp fails like this: ... FAIL: gdb.dwarf2/locexpr-data-member-location.exp: running to bar in runto \ (GDB internal error) ERROR: Could not resync from internal error (eof) ... and takes 1 minute to run. The long running time is caused by running into a timeout in gdb_run_cmd, at this point: ... (gdb) run ^M The program being debugged has been started already.^M Start it from the beginning?

2021-09-04[gdb/testsuite] Check avx support in gdb.arch/amd64-disp-step-avx.expTom de Vries4-83/+103
On a machine on Open Build Service I'm running into a SIGILL for test-case gdb.arch/amd64-disp-step-avx.exp: ...

2021-09-03Use CORE_ADDR as return type from x86_dr_low_get_addrTom Tromey1-1/+1
On a Windows build locally, watchpoints started failing. I tracked this down to x86_dr_low_get_addr returning an 'unsigned long'... in this particular build, this is a 32-bit type, but the inferior is a 64-bit program. This patch fixes the problem by changing the return type. No other change is required, because this matches the function pointer in struct x86_dr_low_type.
2021-09-03Test case reproducing PR28030 bugKevin Buettner4-0/+454
The original reproducer for PR28030 required use of a specific compiler version - gcc-c++-11.1.1-3.fc34 is mentioned in the PR, though it seems probable that other gcc versions might also be able to reproduce the bug as well. This commit introduces a test case which, using the DWARF assembler, provides a reproducer which is independent of the compiler version. (Well, it'll work with whatever compilers the DWARF assembler works with.) To the best of my knowledge, it's also the first test case which uses the DWARF assembler to provide debug info for a shared object. That being the case, I provided more than the usual commentary which should allow this case to be used as a template when a combo shared library / DWARF assembler test case is required in the future. I provide some details regarding the bug in a comment near the beginning of locexpr-dml.exp. This problem was difficult to reproduce; I found myself constantly referring to the backtrace while trying to figure out what (else) I might be missing while trying to create a reproducer. Below is a partial backtrace which I include for posterity. #0 internal_error ( file=0xc50110 "/ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/gdbtypes.c", line=5575, fmt=0xc520c0 "Unexpected type field location kind: %d") at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdbsupport/errors.cc:51 #1 0x00000000006ef0c5 in copy_type_recursive (objfile=0x1635930, type=0x274c260, copied_types=0x30bb290) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/gdbtypes.c:5575 #2 0x00000000006ef382 in copy_type_recursive (objfile=0x1635930, type=0x274ca10, copied_types=0x30bb290) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/gdbtypes.c:5602 #3 0x0000000000a7409a in preserve_one_value (value=0x24269f0, objfile=0x1635930, copied_types=0x30bb290) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/value.c:2529 #4 0x000000000072012a in gdbscm_preserve_values ( extlang=0xc55720 <extension_language_guile>, objfile=0x1635930, copied_types=0x30bb290) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/guile/scm-value.c:94 #5 0x00000000006a3f82 in preserve_ext_lang_values (objfile=0x1635930, copied_types=0x30bb290) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/extension.c:568 #6 0x0000000000a7428d in preserve_values (objfile=0x1635930) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/value.c:2579 #7 0x000000000082d514 in objfile::~objfile (this=0x1635930, __in_chrg=<optimized out>) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/objfiles.c:549 #8 0x0000000000831cc8 in std::_Sp_counted_ptr<objfile*, (__gnu_cxx::_Lock_policy)2>::_M_dispose (this=0x1654580) at /usr/include/c++/11/bits/shared_ptr_base.h:348 #9 0x00000000004e6617 in std::_Sp_counted_base<(__gnu_cxx::_Lock_policy)2>::_M_release (this=0x1654580) at /usr/include/c++/11/bits/shared_ptr_base.h:168 #10 0x00000000004e1d2f in std::__shared_count<(__gnu_cxx::_Lock_policy)2>::~__shared_count (this=0x190bb88, __in_chrg=<optimized out>) at /usr/include/c++/11/bits/shared_ptr_base.h:705 #11 0x000000000082feee in std::__shared_ptr<objfile, (__gnu_cxx::_Lock_policy)2>::~__shared_ptr (this=0x190bb80, __in_chrg=<optimized out>) at /usr/include/c++/11/bits/shared_ptr_base.h:1154 #12 0x000000000082ff0a in std::shared_ptr<objfile>::~shared_ptr ( this=0x190bb80, __in_chrg=<optimized out>) at /usr/include/c++/11/bits/shared_ptr.h:122 #13 0x000000000085ed7e in __gnu_cxx::new_allocator<std::_List_node<std::shared_ptr<objfile> > >::destroy<std::shared_ptr<objfile> > (this=0x114bc00, __p=0x190bb80) at /usr/include/c++/11/ext/new_allocator.h:168 #14 0x000000000085e88d in std::allocator_traits<std::allocator<std::_List_node<std::shared_ptr<objfile> > > >::destroy<std::shared_ptr<objfile> > (__a=..., __p=0x190bb80) at /usr/include/c++/11/bits/alloc_traits.h:531 #15 0x000000000085e50c in std::__cxx11::list<std::shared_ptr<objfile>, std::allocator<std::shared_ptr<objfile> > >::_M_erase (this=0x114bc00, __position= std::shared_ptr<objfile> (expired, weak count 1) = {get() = 0x1635930}) at /usr/include/c++/11/bits/stl_list.h:1925 #16 0x000000000085df0e in std::__cxx11::list<std::shared_ptr<objfile>, std::allocator<std::shared_ptr<objfile> > >::erase (this=0x114bc00, __position= std::shared_ptr<objfile> (expired, weak count 1) = {get() = 0x1635930}) at /usr/include/c++/11/bits/list.tcc:158 #17 0x000000000085c748 in program_space::remove_objfile (this=0x114bbc0, objfile=0x1635930) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/progspace.c:210 #18 0x000000000082d3ae in objfile::unlink (this=0x1635930) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/objfiles.c:487 #19 0x000000000082e68c in objfile_purge_solibs () at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/objfiles.c:875 #20 0x000000000092dd37 in no_shared_libraries (ignored=0x0, from_tty=1) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/solib.c:1236 #21 0x00000000009a37fe in target_pre_inferior (from_tty=1) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/target.c:2496 #22 0x00000000007454d6 in run_command_1 (args=0x0, from_tty=1, run_how=RUN_NORMAL) at /ironwood1/sourceware-git/f34-pr28030/bld/../../worktree-pr28030/gdb/infcmd.c:437 I'll note a few points regarding this backtrace: Frame #1 is where the internal error occurs. It's caused by an unhandled case for FIELD_LOC_KIND_DWARF_BLOCK. The fix for this bug adds support for this case. Frame #22 - it's a partial backtrace - shows that GDB is attempting to (re)run the program. You can see the exact command sequence that was used for reproducing this problem in the PR (at https://sourceware.org/bugzilla/show_bug.cgi?id=28030), but in a nutshell, after starting the program and advancing to the appropriate source line, GDB was asked to step into libstdc++; a "finish" command was issued, returning a value. The fact that a value was returned is very important. GDB was then used to step back into libstdc++. A breakpoint was set on a source line in the library after which a "run" command was issued. Frame #19 shows a call to objfile_purge_solibs. It's aptly named. Frame #7 is a call to the destructor for one of the objfile solibs; it turned out to be the one for libstdc++. Frames #6 thru #3 show various value preservation frames. If you look at preserve_values() in gdb/value.c, the value history is preserved first, followed by internal variables, followed by values for the extension languages (python and guile).

2021-09-03CC_FOR_TARGET et alAlan Modra36-340/+353
The top level Makefile, the ld Makefile and others, define CC_FOR_TARGET to be a compiler for the binutils target machine. This is the compiler that should be used for almost all tests with C source. There are _FOR_TARGET versions of CFLAGS, CXX, and CXXFLAGS too. This was all supposed to work with the testsuite .exp files using CC for the target compiler, and CC_FOR_HOST for the host compiler, with the makefiles passing CC=$CC_FOR_TARGET and CC_FOR_HOST=$CC to the runtest invocation. One exception to the rule of using CC_FOR_TARGET is the native-only ld bootstrap test, which uses the newly built ld to link a copy of itself. Since the files being linked were created with the host compiler, the boostrap test should use CC and CFLAGS, in case some host compiler option provides needed libraries automatically. However, bootstrap.exp used CC where it should have used CC_FOR_HOST. I set about fixing that problem, then decided that playing games in the makefiles with CC was a bad idea. Not only is it confusing, but other dejagnu code knows about CC_FOR_TARGET. See dejagnu/target.exp. So this patch gets rid of the makefile variable renaming and changes all the .exp files to use the correct _FOR_TARGET variables. CC_FOR_HOST and CFLAGS_FOR_HOST disappear.

2021-09-02SHT_SYMTAB_SHNDX handlingAlan Modra3-30/+13
.symtab_shndx section contents is an array, one entry for each symbol in .symtab, present when the number of symbols exceeds a little less than 64k. Since the mapping is 1-1 with symbols there is no need to keep both dest_index and destshndx_index in elf_sym_strtab. Instead, just make sure that the shndx pointers to the swap functions are kept NULL when .symtab_shndx does not exist. Also, strtabcount in the linker's elf hash table is incremented in lock-step with the output symcount, so that can disappear too.
2021-09-02PTR_ADD and NPTR_ADD for bfd.hAlan Modra5-26/+39
This defines a couple of macros used to avoid ubsan complaints about calculations involving NULL pointers. PTR_ADD should be used in the case where it is known that the offset is always zero with a NULL pointer, and you'd like to know if a non-zero offset is ever used. NPTR_ADD should be rarely used, but is defined for cases where a non-zero offset is expected and should be ignored if the pointer is NULL. bfd/ * bfd-in.h (PTR_ADD, NPTR_ADD): Define. * bfd-in2.h: Regenerate. * elf-eh-frame.c (adjust_eh_frame_local_symbols): Avoid NULL pointer calculations. * elflink.c (_bfd_elf_strip_zero_sized_dynamic_sections): Likewise.

2021-09-02obstack.h __PTR_ALIGN vs. ubsanAlan Modra1-3/+3
Current ubsan complains on every use of __PTR_ALIGN (when ptrdiff_t is as large as a pointer), due to making calculations relative to a NULL pointer. This patch avoids the problem by extracting out and simplifying __BPTR_ALIGN for the usual case. I've continued to use ptrdiff_t here, where it might be better to throw away __BPTR_ALIGN entirely and just assume uintptr_t exists. * obstack.h (__PTR_ALIGN): Expand and simplify __BPTR_ALIGN rather than calculating relative to a NULL pointer.

2021-08-31RISC-V: Extend .insn directive to support hardcode encoding.Nelson Chu7-5/+96
The .insn directive can let users use their own instructions, or some new instruction, which haven't supported in the old binutils. For example, if users want to use sifive cache instruction, they cannot just write "cflush.d1.l1" in the assembly code, they should use ".insn i SYSTEM, 0, x0, x10, -0x40". But the .insn directive may not easy to use for some cases, and not so friendly to users. Therefore, I believe most of the users will use ".word 0xfc050073", to encode the instructions directly, rather than use .insn. But once we have supported the mapping symbols, the .word directives are marked as data, so disassembler won't dump them as instructions as usual. I have discussed this with Kito many times, we all think extend the .insn direcitve to support the hardcode encoding, is the easiest way to resolve the problem. Therefore, there are two more .insn formats are proposed as follows, (original) .insn <type>, <operand1>, <operand2>, ... .insn <insn-length>, <value> .insn <value> The <type> is string, and the <insn-length> and <value> are constants. gas/ * config/tc-riscv.c (riscv_ip_hardcode): Similar to riscv_ip, but assembles an instruction according to the hardcode values of .insn directive. * doc/c-riscv.texi: Document two new .insn formats. * testsuite/gas/riscv/insn-fail.d: New testcases. * testsuite/gas/riscv/insn-fail.l: Likewise. * testsuite/gas/riscv/insn-fail.s: Likewise. * testsuite/gas/riscv/insn.d: Updated. * testsuite/gas/riscv/insn.s: Likewise.
2021-08-30Use gdbfmt for vprintf_filtered.John Baldwin1-17/+9
gdbfmt was already used for printf_filtered, so using it for vprintf_filtered is more consistent. As a result, all callers of vfprintf_maybe_filtered now use gdbfmt, so the function can be simplified to assume the gdbfmt case and remove the associated bool argument. Similary, vprintf_filtered is now a simple wrapper around vfprintf_filtered.

2021-08-30fbsd-nat: Don't use '%jd' and '%ju' with printf_filtered.John Baldwin1-22/+23
The handler for 'info proc status' for native processes on FreeBSD uses the 'j' size modifier along with uintmax_t / intmax_t casts to output integer values for types such as off_t that are not aliases of a basic C type such as 'int' or 'long'. printf_filtered does not support the 'j' modifer, so this resulted in runtime errors in practice: (gdb) info proc stat process 8674 Name: ls State: T (stopped) Parent process: 8673 Process group: 8674 Session id: 2779 Unrecognized format specifier 'j' in printf Instead, use plongest and pulongest to generate the output strings of these integer values.
