2023-11-07Add minimal thread-safety to BFDTom Tromey7-55/+299
This patch provides some minimal thread-safety to BFD. The BFD client can request thread-safety by providing a lock and unlock function. The globals used during BFD creation (e.g., bfd_id_counter) are then locked, and the file descriptor cache is also locked. A function to clean up any thread-local data is now provided for BFD clients. * bfd-in2.h: Regenerate. * bfd.c (lock_fn, unlock_fn): New globals. (bfd_thread_init, bfd_thread_cleanup, bfd_lock, bfd_unlock): New functions. * cache.c (bfd_cache_lookup_worker): Use _bfd_open_file_unlocked. (cache_btell, cache_bseek, cache_bread, cache_bwrite): Lock and unlock. (cache_bclose): Add comment. (cache_bflush, cache_bstat, cache_bmmap): Lock and unlock.

2023-11-07aarch64: Add 128-bit system register flagsVictor Do Nascimento2-10/+13
In preparation for the implementation of 128-bit system register support across the toolchain, this patch adds the feature flag F_REG_128 and adds it to relevant system registers in `aarch64-sys-regs.def'. Given the shared nature of this file, this change is made necessary initially to implement argument validation in the `__arm_rsr128' and `__armwsr128' ACLE intrinsics in GCC, but will be of subsequent use in the binutils implementation of the corresponding `mrrs' and `msrr' instructions. Regression tested on aarch64-linux-gnu, no regressions. opcodes/ChangeLog: * aarch64-opc.h (F_REG_128): New flag. * aarch64-sys-regs.def (par_el1): Add F_REG_128 flag. (rcwmask_el1): Likewise.

2023-11-07gdb/arm: remove thumb bit in arm_adjust_breakpoint_addressSimon Marchi1-3/+6
When compiling gdb with -fsanitize=address on ARM, I get a crash in test gdb.arch/arm-disp-step.exp, reproduced easily with: $ ./gdb -nx -q --data-directory=data-directory testsuite/outputs/gdb.arch/arm-disp-step/arm-disp-step -ex "break *test_call_end" Reading symbols from testsuite/outputs/gdb.arch/arm-disp-step/arm-disp-step... ================================================================= ==23295==ERROR: AddressSanitizer: heap-buffer-overflow on address 0xb4a14fd1 at pc 0x01a48871 bp 0xbeab8490 sp 0xbeab8494 Since it doesn't require running the program, it can be reproduced locally on a dev machine other than ARM, after acquiring the test binary. The length of the allocate buffer `buf` is 1, and we try to extract an integer of size 2 from it. The length of 1 comes from the subtraction `bpaddr - boundary`. Normally, on ARM, all instructions are aligned on a multiple of 2, so it's weird for this subtraction to result in 1. In this case, boundary comes from the result of find_pc_partial_function returning 0x549: (gdb) p/x bpaddr $2 = 0x54a (gdb) p/x boundary $3 = 0x549 (gdb) p/x bpaddr - boundary $4 = 0x1 0x549 is the address of the test_call_subr label, 0x548, with the thumb bit enabled. Before doing some math with the address, I think we need to strip the thumb bit, like is done elsewhere (for instance for bpaddr earlier in the same function). I wonder if find_pc_partial_function should do that itself, in order to return an address that is suitable for arithmetic. In any case, that would be a change with a broad impact, so for now just fix the issue locally. After the patch: $ ./gdb -nx -q --data-directory=data-directory testsuite/outputs/gdb.arch/arm-disp-step/arm-disp-step -ex "break *test_call_end" Reading symbols from testsuite/outputs/gdb.arch/arm-disp-step/arm-disp-step...

2023-11-07ld/x86: reduce testsuite dependency on system object filesJan Beulich4-94/+131
PR ld/30722 Tests looking for certain .note-section recorded properties may not involve object files from the underlying platform (e.g. via using the C compiler for linking): Such object files may themselves have similar note sections, and hence they may influence the overall outcome. For now convert just the tests known to be affected by crt*.o coming with "ISA v3 needed" notes. Eventually other tests ought to be converted, too.

2023-11-05Pre-read DWZ file in DWARF readerTom Tromey5-23/+31
While working on background reading of DWARF, I came across the DWZ-reading code. This code can query the user (via the debuginfod support) -- something that cannot be done off the main thread. Looking into it, I realized that this code can be run much earlier, avoiding this problem. Digging a bit deeper, I also found a discrepancy here between how the DWARF reader works in "readnow" mode as compared to the normal modes. This patch cleans this up by trying to read the DWZ file earlier, and also by having the DWARF reader convert any exception here into a warning. This unifies the various cases, but also makes it so that errors do not prevent gdb from continuing on to the extent possible. Regression tested on x86-64 Fedora 38.

2023-11-03gdbsupport: mark array_view::slice with [[nodiscard]]Simon Marchi1-0/+2
I (almost) had a bug where I did: buffer.slice (...) but I meant: buffer = buffer.slice (...) The first one does nothing, it creates a new array_view but without using it, it's useless. Mark the slice methods with [[nodiscard]] (which is standard C++17) so that error would generate a warning. I guess that many functions could be marked as nodiscard, essentially function that is pure (doesn't have side-effects). But this one seems particularly easy to mis-use.

Since "maint selftest" now runs quite a lot of tests (especially in an all-targets build), I thought it would be useful to print a summary at the end of what failed. So, implement that. Print the summary before the "Ran %d unit tests, %zu failed\n" line, so that that one remains the last line, and the gdb.gdb/unittest.exp doesn't need to be changed. The output looks like (if I force a failure in a test): (gdb) maint selftest ... Running selftest value_copy. Running selftest xml_escape_text. Running selftest xml_escape_text_append. Failures: aarch64-analyze-prologue Ran 4134 unit tests, 1 failed (gdb) Change-Id: If3aaabdd6f8078d0e6e50e8d08f3e558ab85277e Approved-By: Tom Tromey <tom@tromey.com>

Within the groups L{B,BU,H,HU,W,WU,D}, S{B,H,W,D}, FL{H,W,D,Q}, and FS{H,W,D,Q} the sole difference between the handling is the insn mnemonic passed to the common handling functions. The intended mnemonic, however, can easily be retrieved. Furthermore leverags that Sx and FSx are then handled identically, too, and hence their cases can also be folded.

2023-11-02[gdb/tdep] Fix nr array elements in ppc64_aggregate_candidateTom de Vries1-1/+5
On AlmaLinux 9.2 powerpc64le I run into: ... (gdb) PASS: gdb.ada/array_return.exp: continuing to Create_Small_Float_Vector finish^M Run till exit from #0 pck.create_small_float_vector () at pck.adb:30^M 0x00000000100022d4 in p () at p.adb:25^M 25 Vector := Create_Small_Float_Vector;^M Value returned is $3 = (2.80259693e-45, 2.80259693e-45)^M (gdb) FAIL: gdb.ada/array_return.exp: value printed by finish of Create_Small_Float_Vector ... while this is expected: ... Value returned is $3 = (4.25, 4.25)^M ... The problem is here in ppc64_aggregate_candidate: ... if (!get_array_bounds (type, &low_bound, &high_bound)) return -1; count *= high_bound - low_bound ... The array type (containing 2 elements) is: ... type Small_Float_Vector is array (1 .. 2) of Float; ... so we have: ... (gdb) p low_bound $1 = 1 (gdb) p high_bound $2 = 2 ... but we calculate the number of elements in the array using "high_bound - low_bound", which is 1. Consequently, gdb fails to correctly classify the type as a ELFv2 homogeneous aggregate. Fix this by calculating the number of elements in the array by using "high_bound - low_bound + 1" instead. Furthermore, high_bound can (in general, though perhaps not here) also be smaller than low_bound, so to be safe take that into account as well: ... LONGEST nr_array_elements = (low_bound > high_bound ? 0 : (high_bound - low_bound + 1)); count *= nr_array_elements; ... Tested on powerpc64le-linux.

2023-11-02aarch64: Add GCS system registers.Srinath Parvathaneni5-0/+83
This patch adds support for 10 new AArch64 system registers (gcscre0_el1, gcscr_el1, gcscr_el12, gcscr_el2, gcscr_el3, gcspr_el0, gcspr_el1 ,gcspr_el12, gcspr_el2 and gcspr_el3), which are enabled on using Guarded Control Stack (+gcs flag) feature.
2023-11-02aarch64: Add support for GCSB DSYNC instruction.Srinath Parvathaneni13-2299/+2295
This patch adds support for Guarded control stack data synchronization instruction (GCSB DSYNC). This instruction is allocated to existing HINT space and uses the HINT number 19 and to match this an entry is added to the aarch64_hint_options array.
2023-11-02aarch64: Add support for GCS extension.srinath12-2511/+2688
This patch adds for Guarded Control Stack Extension (GCS) extension. GCS feature is optional from Armv9.4-A architecture and enabled by passing +gcs option to -march (eg: -march=armv9.4-a+gcs) or using ".arch_extension gcs" directive in the assembly file. Also this patch adds support for GCS instructions gcspushx, gcspopcx, gcspopx, gcsss1, gcsss2, gcspushm, gcspopm, gcsstr and gcssttr.
2023-11-02aarch64: Add support for Check Feature Status Extension.Srinath Parvathaneni12-12/+83
This patch adds support for Check Feature Status Extension (CHK) which is mandatory from Armv8.0-A. Also this patch supports "chkfeat" instruction (hint #40).
2023-11-02aarch64: Add support for Armv8.9-A and Armv9.4-A Architectures.srinath4-3/+14
This patch adds AArch64 support for Armv8.9-A architecture (-march=armv8.9-a) and Armv9.4-A architecture (-march=armv9.4-a).

2023-11-01[gdb/symtab] Work around gas PR28629Tom de Vries4-1/+130
When running test-case gdb.tui/tui-layout-asm-short-prog.exp on AlmaLinux 9.2 ppc64le, I run into: ... FAIL: gdb.tui/tui-layout-asm-short-prog.exp: check asm box contents ... The problem is that we get: ... 7 [ No Assembly Available ] ... because tui_get_begin_asm_address doesn't succeed. In more detail, tui_get_begin_asm_address calls: ... find_line_pc (sal.symtab, sal.line, &addr); ... with: ... (gdb) p *sal.symtab $5 = {next = 0x130393c0, m_compunit = 0x130392f0, m_linetable = 0x0, filename = "tui-layout-asm-short-prog.S", filename_for_id = "$gdb/build/gdb/testsuite/tui-layout-asm-short-prog.S", m_language = language_asm, fullname = 0x0} (gdb) p sal.line $6 = 1 ... The problem is the filename_for_id which is the source file prefixed with the compilation dir rather than the source dir. This is due to faulty debug info generated by gas, PR28629: ... <1a> DW_AT_name : tui-layout-asm-short-prog.S <1e> DW_AT_comp_dir : $gdb/build/gdb/testsuite <22> DW_AT_producer : GNU AS 2.35.2 ... The DW_AT_name is relative, and it's relative to the DW_AT_comp_dir entry, making the effective name $gdb/build/gdb/testsuite/tui-layout-asm-short-prog.S. The bug is fixed starting version 2.38, where we get instead: ... <1a> DW_AT_name : $gdb/src/gdb/testsuite/gdb.tui/tui-layout-asm-short-prog.S <1e> DW_AT_comp_dir : $gdb/build/gdb/testsuite <22> DW_AT_producer : GNU AS 2.38 ... Work around the faulty debug info by constructing the filename_for_id using the second directory from the directory table in the .debug_line header: ... The Directory Table (offset 0x22, lines 2, columns 1): Entry Name 0 $gdb/build/gdb/testsuite 1 $gdb/src/gdb/testsuite/gdb.tui ... Note that the used gas contains a backport of commit 3417bfca676 ("GAS: DWARF-5: Ensure that the 0'th entry in the directory table contains the current working directory."), because directory 0 is correct. With the unpatched 2.35.2 release the directory 0 entry is incorrect: it's a copy of entry 1. Add a dwarf assembly test-case that reflects the debug info as generated by unpatched gas 2.35.2. Tested on x86_64-linux. Approved-By: Tom Tromey <tom@tromey.com>
