2022-09-21gdb: add type::length / type::set_lengthSimon Marchi14-116/+119
Add the `length` and `set_length` methods on `struct type`, in order to remove the `TYPE_LENGTH` macro. In this patch, the macro is changed to use the getter, so all the call sites of the macro that are used as a setter are changed to use the setter method directly. The next patch will remove the macro completely. Change-Id: Id1090244f15c9856969b9be5006aefe8d8897ca4

2022-09-21RISC-V: Fix riscv_set_tso declarationTsukasa OI1-1/+1

2022-09-21RISC-V: Set EF_RISCV_TSO also on .option archTsukasa OI1-0/+3
This is a minor fix to commit 96462b012988d35ebb1137a2ad9fd0a96547d79a ("RISC-V: Implement Ztso extension"). Currently, it sets EF_RISCV_TSO ELF flag when initial ISA string contains the 'Ztso' extension. However, GAS has a way to update the ISA string: ".option arch". When the architecture is updated by ".option arch", EF_RISCV_RVC ELF flag is set when the 'C' extension is detected. Analogously, this commit sets the EF_RISCV_TSO when the 'Ztso' extension is detected. gas/ChangeLog: * config/tc-riscv.c (s_riscv_option): Set TSO ELF flag if the 'Ztso' extension is specified via ".option arch" directive.
2022-09-21PR29573, addr2line doesn't display file/line for local symbolsAlan Modra1-18/+16
The DWARF standard is clear that DW_AT_linkage_name is optional. Compilers may not provide the attribute on functions and variables, even though the language mangles names. g++ does not for local variables and functions. Without DW_AT_linkage_name, mangled object file symbols can't be directly matched against the source-level DW_AT_name in DWARF info. One possibility is demangling the object file symbols, but that comes with its own set of problems: 1) A demangler might not be available for the compiler/language. 2) Demangling doesn't give the source function name as stored in DW_AT_name. Class and template parameters must be stripped at least. So this patch takes a simpler approach. A symbol matches DWARF info if the DWARF address matches the symbol address, and if the symbol name contains the DWARF name as a sub-string. Very likely the name matching is entirely superfluous. PR 29573 * dwarf.c (lookup_symbol_in_function_table): Match a symbol containing the DWARF source name as a substring. (lookup_symbol_in_variable_table): Likewise.

2022-09-21dwarf2.c remove varinfo and funcinfo sec fieldAlan Modra1-19/+3
The "sec" field in these structures is only set and used in lookup functions. It always starts off as NULL. So the only possible effect of the field is to modify the return of the lookup, which was its purpose back in 2005 when HJ fixed PR990. Since then we solved the problem of relocatable object files with the fix for PR2338, so this field is now redundant. * dwarf.c (struct funcinfo, struct varinfo): Remove "sec" field. (lookup_symbol_in_function_table): Don't set or test "sec". (lookup_symbol_in_variable_table): Likewise. (info_hash_lookup_funcinfo, info_hash_lookup_varinfo): Likewise.
2022-09-21configure: Pass CPPFLAGS_FOR_BUILD to subdirsTsukasa OI2-0/+5
Because CPPFLAGS_FOR_BUILD is used in some subdirectories (through bfd/warning.m4), not AC_SUBSTing the variable causes minor issues. Fortunately, it didn't cause severe errors but error messages related to @CPPFLAGS_FOR_BUILD@ (not AC_SUBSTed CPPFLAGS_FOR_BUILD variable passed to subdirectories through Makefile) remain in config.log. To avoid invalid invocation of preprocessor for build environment, we need to set proper CPPFLAGS_FOR_BUILD (may be empty) and pass it to subdirectories that need it. This is what this commit does. ChangeLog: * configure.ac: Pass CPPFLAGS_FOR_BUILD to subdirectories. * configure: Regenerate.

2022-09-21RISC-V: Always generate R_RISCV_CALL_PLT reloc for call in assembler.Nelson Chu4-36/+32
Since we have the same behaviors of CALL and CALL_PLT relocs in linker for now, https://github.com/bminor/binutils-gdb/commit/3b1450b38c644f99aa2e211747b428b9f8d15cca And the psabi already deprecate the CALL reloc, https://github.com/riscv-non-isa/riscv-elf-psabi-doc/commit/a0dced85018d7a0ec17023c9389cbd70b1dbc1b0 Therefore, we should always generate R_RISCV_CALL_PLT reloc for call, even if it has @plt postfix. I believe LLVM (https://reviews.llvm.org/D132530) already support this, so GNU as should do the same thing. gas/ * config/tc-riscv.c (riscv_ip): Always generate CALL_PLT reloc for call, even if it has @plt postfix. * testsuite/gas/riscv/no-relax-reloc.d: Updated CALL to CALL_PLT. * testsuite/gas/riscv/relax-reloc.d: Likewise. ld/ * testsuite/ld-riscv-elf/variant_cc-r.d: Updated CALL to CALL_PLT.

2022-09-21looping in alpha_vms_slurp_relocsAlan Modra1-24/+33
The direct cause for the looping was failing to test for error return from _bfd_vms_get_object_record inside a while(1) loop. Fix that.

2022-09-20gdb/testsuite: add a debuginfod-support.exp helper libraryAndrew Burgess2-111/+243
We currently have a single test for GDB's debuginfod support, this is gdb.debuginfod/fetch_src_and_symbols.exp, this script does all the setup, starts debuginfod, and then does the testing. This commit tries to split the existing script in two, there is a new library lib/debuginfod-support.exp, which contains a helper functions related to running debuginfod tests. All the code in the new library is basically copied from the existing test case (which is why I retained the copyright date range on the new library), with some minor adjustments to try and make the code a little more generic. One change I made, for example, is the library offers functions to shut down debuginfod, previously we just relied on expect shutting down debuginfod when dejagnu completed. The existing test script is updated to make use of the new library code, and this test is still passing for me. The only change in the test results is a single test where I changed the name to remove the port number from the test name - the port number can change from run to run, so could make it hard to compare test results. I have also done a little light house keeping on the original test script, updating and adding new comments, and making use of proc_with_prefix in a couple of places.

2022-09-20LoongArch: Fix R_LARCH_IRELATIVE insertion after elf_link_sort_relocsXi Ruoyao4-17/+63
loongarch_elf_finish_dynamic_symbol is called after elf_link_sort_relocs if -z combreloc. elf_link_sort_relocs redistributes the contents of .rela.* sections those would be merged into .rela.dyn, so the slot for R_LARCH_IRELATIVE may be out of relplt->contents now. To make things worse, the boundary check dyn < dyn + relplt->size / sizeof (*dyn) is obviously wrong ("x + 10 < x"? :), causing the issue undetected during the linking process and the resulted executable suddenly crashes at runtime. The issue was found during an attempt to add static-pie support to the toolchain. Fix it by iterating through the inputs of .rela.dyn to find the slot.
2022-09-20LoongArch: Don't write into GOT for local ifuncXi Ruoyao1-2/+3
Local ifuncs are always resolved at runtime via R_LARCH_IRELATIVE, so there is no need to write anything into GOT. And when we write the GOT we actually trigger a heap-buffer-overflow: If a and b are different sections, we cannot access something in b with "a->contents + (offset from a)" because "a->contents" and "b->contents" are heap buffers allocated separately, not slices of a large buffer. So stop writing into GOT for local ifunc now.

2022-09-16BFD error message suppression test caseKevin Buettner2-0/+229
This commit adds a GDB test case which tests GDB's BFD error handler hook for suppressing output of all but the first identical messages. See the comment at the beginning of bfd-errors.exp for details about this new test. I've tested this test for both 32- and 64-bit ELF files and also on both little endian and big endian machines. It also works for both native and remote targets. The only major restriction is that it only works for ELF targets.
2022-09-16Suppress printing of superfluous BFD error messagesKevin Buettner1-0/+67
This commit adds a hook to the BFD error handler for suppressing identical messages which have been output once already. It's motivated by this Fedora bug... https://bugzilla.redhat.com/show_bug.cgi?id=2083315 ...in which over 900,000 BFD error messages are output when attaching to firefox. From the bug report, the messages all say: BFD: /usr/lib/debug/usr/lib64/firefox/libxul.so-100.0-2.fc35.x86_64.debug: attempt to load strings from a non-string section (number 38) Since there's no (additional) context which might assist the user in determining what's wrong, there's really no point in outputting more than one message. Of course, if BFD should output some other/different message, it should be output too, but all future messages identical to those already output should be suppressed. For the firefox problem, it turned out that there were only 37 sections, but something was referring to section #38. I haven't investigated further to find out how this came to be. Despite this problem, useful debugging might still be done, especially if the user doesn't care about debugging the problematic library. If it turns out that knowing the quantity of messages might be useful, I've implemented the suppression mechanism by keeping a count of each identical message. A new GDB command, perhaps a 'maintenance' command, could be added to print out each message along with the count. I haven't implemented this though because I'm not convinced of its utility. Also, the BFD message printer has support for BFD- specific format specifiers. The BFD message strings that GDB stores in its map are sufficient for distinguishing messages from each other, but are not identical to those output by BFD's default error handler. So, that problem would need to be solved too.

2022-09-16[gdb] Handle pending ^C after rl_callback_read_charTom de Vries1-0/+16
In completion tests in various test-cases, we've been running into these "clearing input line" timeouts: ...

AFAIU, the following scenario happens: - expect sends "$cmd\t" - gdb detects the stdin event, and calls rl_callback_read_char until it comes to handle \t - readline interprets the \t as completion, tries to complete, fails to do so, outputs a bell (^G) - expect sees the bell, and proceeds to send ^C - readline is still in the call to rl_callback_read_char, and stores the signal in _rl_caught_signal - readline returns from the call to rl_callback_read_char, without having handled _rl_caught_signal - gdb goes to wait for the next event - expect times out waiting for "Quit", the expected reaction for ^C Fix this by handling pending signals after each call to rl_callback_read_char. The fix is only available for readline 8.x, if --with-system-readline provides an older version, then the fix is disabled due to missing function rl_check_signals. Tested on x86_64-linux.

2022-09-14looping in bfd_mach_o_fat_openr_next_archived_fileAlan Modra1-4/+23
mach-o.c doesn't sanity check mach-o-fat archives, making it easy for fuzzers to create an archive with mach_o_fat_archentry headers that point to the same offset. bfd_mach_o_fat_openr_next_archived_file uses the previous element offset to find its header, and thus the next element. If two offsets are the same, any tool reading the archive will get stuck. This patch rejects such archives, and any with overlapping elements. * mach-o.c (overlap_previous): New function. (bfd_mach_o_fat_archive_p): Sanity check that elements do not overlap each other or the file and archive headers.
