dwarf: Read register number as unsigned in DW_CFA_def_cfa* When displaying the .debug_frame section, the register numbers in the DW_CFA_def_cfa* statements are read as signed numbers. I have come across a target that has register 121, encoded as 0x79 in unsigned LEB128. Interpreting this as signed results in -7, which makes readelf display "r-7". The DWARF5 standard (6.4.2.2) states that the register numbers should be treated as unsigned LEB128. Simply replacing READ_SLEB with READ_ULEB resulted in warnings like these: /home/emaisin/src/binutils-gdb/binutils/dwarf.c: In function ‘display_debug_frames’: /home/emaisin/src/binutils-gdb/binutils/dwarf.c:355:17: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare] if ((var) != _val) \ ^ /home/emaisin/src/binutils-gdb/binutils/dwarf.c:7866:8: note: in expansion of macro ‘READ_ULEB’ READ_ULEB (fc->cfa_reg); ^ ... so I also changed Frame_Chunk::cfa_reg to an unsigned int. binutils/ChangeLog: * dwarf.c (struct Frame_Chunk) <cfa_reg>: Change type to unsigned int. (display_debug_frames): Read CFA reg as an unsigned number.

Asynchronous insertion for dwarf-mode.el I was recently examining a very large .debug file. I tried to use dwarf-mode, but it blocked Emacs for a very long time while reading output.

DWARF header checks This patch tidies DWARF header checks, consolidating the "negative" checks (which are really overflow checks) with the section size check. In a number of cases this also ensures that small negative lengths are caught. For instance hdrptr = start + arange.ar_length + initial_length_size; if (hdrptr < start || hdrptr > end) does not detect ar_length in the range [-initial_length_size,-1]. * dwarf.c (process_debug_info): Consolidate header length checks.

Avoid spurious readelf error status from decode_arm_unwind. readelf.c:decode_arm_unwind has a variable res that is used as a return value, with FALSE meaning unsuccessful and TRUE meaning successful. This is initialized to FALSE (and then various code in the function sets it to FALSE again on error), meaning that when the function is successful, if it reaches returning res is still returns FALSE, resulting eventually in exit status 1 from readelf without any error message to indicate an error. This patch fixes the initialization to use TRUE, so avoiding those spurious errors. I don't have a self-contained test for this issue; it was observed as many prelink tests failing without the patch and passing with it. * readelf.c (decode_arm_unwind): Initialize res to TRUE.

LVU: dump loclists with locviews When dumping location lists, also dump locview lists that may be interspersed with them, and bring view pairs next to the corresponding location list entries. This patch supports DW_AT_GNU_locviews as a separate attribute for DWARF4- loc_lists and split (dwo) loclists, as well as DWARF5 loclists. It also supports, in DWARF5 loclists, the proposed DW_LLE_GNU_view_pair loclist entry type proposed for DWARF6. The tests use 32-bit DWARF, even on 64-bit targets, resolving offsets to constants so as to reduce the risk that relocations be created for them, or that the offsets be rejected as nonconstants. The patch also adds an xfail to an unrelated test, namely dw5, so that no unexpected fails remain on nds32*-elf, one of the tested targets.

strings: remove section/file size check This reverts most of 06803313754, 2005-07-05 Dmitry V. Levin change adding a check that section size doesn't exceed file size. As we've seen recently with mmo tests, decoded section size can easily exceed file size with formats that encode section data. I've also changed "strings" to use bfd_malloc_and_get_section, so that "strings" won't die on a malloc failure. I think it's better to continue on looking at other sections after failing to dump a section with fuzzed size. The testcases at https://bugzilla.altlinux.org/show_bug.cgi?id=5871 on a 32-bit host now produce $ strings -d --target=a.out-i386 /tmp/bfdkiller.dat strings: error: /tmp/bfdkiller.dat(.text) is too large (0xffffffff bytes) strings: /tmp/bfdkiller.dat: Reading section .text failed: Memory exhausted strings: /tmp/bfdkiller.dat: Reading section .data failed: File truncated org.ec $ strings -d --target=a.out-i386 /tmp/eclipse-state strings: /tmp/eclipse-state: Reading section .text failed: File truncated org.eclipse.osgi System Bundle [snip] * strings.c (filename_and_size_t): Delete.

MIPS: Fix XPA base and Virtualization ASE instruction handling Correct a commit 7d64c587c15f ("Add support for the MIPS eXtended Physical Address (XPA) ASE.") bug, causing XPA base and Virtualization ASE instructions to be wrongly always enabled with the selection of the MIPS32r2 or higher ISA. For example this source assembles successfully as shown below: $ cat xpa.s mfhc0 $2, $1 $ as -32 -mips32 -o xpa.o xpa.s xpa.s: Assembler messages: xpa.s:1: Error: opcode not supported on this processor: mips32 (mips32) `mfhc0 $2,$1' $ as -32 -mips32r2 -o xpa.o xpa.s $ objdump -d xpa.o xpa.o: file format elf32-tradbigmips Disassembly of section .text: 00000000 <.text>: 0: 40420800 mfhc0 v0,c0_random ... $ To address this issue remove the I33 (INSN_ISA32R2) marking from all XPA instructions in the opcode table. Additionally, for XPA Virtualization ASE instructions implement an XPAVZ (ASE_XPA_VIRT) combination ASE flag and use it in place of IVIRT|XPA (ASE_VIRT|ASE_XPA). Now the same source is correctly rejected unless the `-mxpa' option is also used: $ as -32 -mips32r2 -o xpa.o xpa.s xpa.s: Assembler messages: xpa.s:1: Error: opcode not supported on this processor: mips32r2 (mips32r2) `mfhc0 $2,$1' $ as -32 -mips32r2 -mxpa -o xpa.o xpa.s $ Add test cases for XPA base and XPA Virtualization ASE instructions.

[ARC] Fix handling of cpu=... disassembler option value There is a bug in handling of cpu=... disassembler option in case there are other options after it, for example, `cpu=EM,dsp'. In this case `EM,dsp' is treated as an option value, and strcasecmp reports is as non-equal to "EM". This is fixed by using disassembler_options_cmp function, which compares string treating `,' the same way as `\0'. This function also solves a problem with option order in parse_option. Previously, if several option had same prefix (e.g. fpud, fpuda), then the longer one should have been compared first, otherwise when longer option is passed it would be treated as a short one, because CONST_STRNEQ ("fpud", "fpuda") would be true. The order of options was correct for ARC, so there were no bugs per se, but with disassembler_option_cmp there is no risk of such a bug being introduced in the future. opcodes/ChangeLog: yyyy-mm-dd Anton Kolesov <Anton.Kolesov@synopsys.com> * arc-dis.c (parse_option): Use disassembler_options_cmp to compare disassembler option strings.

[ARM] Add support for ARMv8-R in assembler and readelf === Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to add support for ARMv8-R in GAS: instructions, build attributes and readelf. === Patch description === Although some differences exist for system registers, from GAS point of view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state and a subset of its extensions. This patch therefore introduce a new feature bit to distinguish the availability of the pan, ras and rdma extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd extensions to be used by ARMv8-R. Most of the changes are then in the testsuite to (i) rename source files and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename files with expected output for ARMv8-A build attributes and (iii) add new files with expected output for ARMv8-R build attributes. 2017-06-24 Thomas Preud'homme <thomas.preudhomme@arm.com> binutils/ * readelf.c (arm_attr_tag_CPU_arch): Fill value for ARMv8-R. gas/ * NEWS: Mention support for ARMv8-R architecture. * config/tc-arm.c (arm_archs): Add entry for ARMv8-R.

x86: Support Intel IBT with IBT property and IBT-enable PLT To support IBT in Intel Control-flow Enforcement Technology (CET) instructions: https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf #define GNU_PROPERTY_X86_FEATURE_1_AND 0xc0000002 #define GNU_PROPERTY_X86_FEATURE_1_IBT (1U << 0) are added to GNU program properties to indicate that all executable sections are compatible with IBT when ENDBR instruction starts each valid target where an indirect branch instruction can land. GNU_PROPERTY_X86_FEATURE_1_IBT is set on output only if it is set on all relocatable inputs. The followings changes are made to the Procedure Linkage Table (PLT): 1. For 64-bit x86-64, PLT is changed to PLT0: push GOT[1] bnd jmp *GOT[2] nop ... PLTn: endbr64 push namen_reloc_index bnd jmp PLT0 together with the second PLT section: PLTn: endbr64 bnd jmp *GOT[namen_index] nop BND prefix is also added so that IBT-enabled PLT is compatible with MPX. 2. For 32-bit x86-64 (x32) and i386, PLT is changed to PLT0: push GOT[1] jmp *GOT[2] nop ... PLTn: endbr64 # endbr32 for i386. push namen_reloc_index jmp PLT0 together with the second PLT section: PLTn: endbr64 # endbr32 for i386. jmp *GOT[namen_index] nop BND prefix isn't used since MPX isn't supported on x32 and BND registers aren't used in parameter passing on i386. GOT is an array of addresses. Initially, GOT[namen_index] is filled with the address of the ENDBR instruction of the corresponding entry in the first PLT section. The function, namen, is called via the ENDBR instruction in the second PLT entry. GOT[namen_index] is updated to the actual address of the function, namen, at run-time. 2 linker command line options are added: 1. -z ibtplt: Generate IBT-enabled PLT. 2. -z ibt: Generate GNU_PROPERTY_X86_FEATURE_1_IBT in GNU program properties as well as IBT-enabled PLT. bfd/ * elf32-i386.c (elf_i386_lazy_ibt_plt0_entry): New.

[ARC] Allow CPU to be enforced via disassemble_info options Currently print_insn_arc relies on BFD mach and ELF private headers to distinguish between various ARC architectures. Sometimes those values are not correct or available, mainly in the case of debugging targets without and ELF file available. Changing a BFD mach is not a problem for the debugger, because this is a generic BFD field, and GDB, for example, already sets it according to information provided in XML target description or specified via GDB 'set arch' command. However, things are more complicated for ELF private headers, since it requires existing of an actual ELF file. To workaround this problem this patch allows CPU model to be specified via disassemble info options. If CPU is specified in options, then it will take a higher precedence than whatever might be specified in ELF file. This is mostly needed for ARC EM and ARC HS, because they have the same "architecture" (mach) ARCv2 and differ in their private ELF headers. Other ARC architectures can be distinguished between each other purely via "mach" field. Proposed disassemble option format is "cpu=<CPU>", where CPU can be any valid ARC CPU name as supported by GAS. Note that this creates a seeming redundancy with objdump -m/--architecture option, however -mEM and -mHS still result in "ARCv2" architecture internally, while -Mcpu={HS,EM} would have an actual effect on disassembler. opcodes/ChangeLog: yyyy-mm-dd Anton Kolesov <anton.kolesov@synopsys.com> * arc-dis.c (enforced_isa_mask): Declare.

Refactor disassembler selection Nowadays, opcodes/disassemble.c:disassembler selects the proper disassembler according to ABFD only. However, it actually selects disassemblers according to arch, mach, endianess, and abfd. This patch adds them to the parameters of disassembler, so that its caller can still select disassemblers in case that abfd is NULL (a typical case in GDB).

binutils: remove sparc64/mips64 workaround in objcopy build notes merge code This patch removes a workaround recently installed in objcopy that avoided removing duplicated notes in targets for which the number of internal relocations may be bigger than the number of external relocations.

* objcopy.c (merge_gnu_build_notes): Remove workaround that
prevented deleting relocations in duplicated notes in mips64 and
sparc.
MIPS/BFD: For n64 hold the number of internal relocs in `->reloc_count' Revert parts of commit fee24f1c5bfe ("objdump improvements for mips elf64"), <https://sourceware.org/ml/binutils/2003-03/msg00108.html>, and make the `->reloc_count' member of `struct bfd_section' hold the actual number of internal relocations stored in its `->relocation' vector. To do so adjust `mips_elf64_slurp_one_reloc_table' to set `->reloc_count' to the actual number of internal relocations retrieved and discard `mips_elf64_canonicalize_reloc', `mips_elf64_canonicalize_dynamic_reloc' and their corresponding target macros. Contrary to the description of `mips_elf64_slurp_one_reloc_table', adjusted appropriately, this makes generic relocation processing code happy and satisfies the "merge notes section" binutils test case. Add extra binutils test cases to expand the coverage of the generic "merge notes section" test case, now passing with the n64 ABI, across the MIPS o32, n32 and n64 ABIs regardless of the default ABI selected in target configuration, and also to verify correctness of the relocations produced. Conversely, do not provide any additional test cases for the original issue addressed with the commit referred: - objdump would display only 1/3 of the total number of relocations, because it used the external relocation count, but each external relocation is brought in as 3 internal relocations. as n64 ABI relocation processing with `objdump -r' and `objdump -R' is already widely covered across the GAS and LD test suites. bfd/ * elf64-mips.c (mips_elf64_canonicalize_reloc): Remove prototype and function.

MIPS16e2: Add MIPS16e2 ASE support Add MIPS16e2 ASE support as per the architecture specification[1], including in particular: 1. A new ELF ASE flag to mark MIPS16e2 binaries. 2. MIPS16e2 instruction assembly support, including a relaxation update to use LUI rather than an LI/SLL instruction pair for loading the high part of 32-bit addresses. 3. MIPS16e2 instruction disassembly support, including updated rules for extended forms of instructions that are now subdecoded and therefore do not alias to the original MIPS16 ISA revision instructions even for encodings that are not valid in the MIPS16e2 instruction set. Add `-mmips16e2' and `-mno-mips16e2' GAS command-line options and their corresponding `mips16e2' and `no-mips16e2' settings for the `.set' and `.module' pseudo-ops. Control the availability of the MT ASE subset of the MIPS16e2 instruction set with a combination of these controls and the preexisting MT ASE controls.

MIPS/readelf: With `-A' also dump GOT in static binaries A static, non-relocated global offset table will be embedded in static binaries produced from objects containing any kind of GOT relocations, generally PIC code. All symbols will have been resolved in static link in such binaries making all GOT entries local and their values final as there is no run-time load processing further performed. Dump such GOT with `readelf -A' like already done with regular GOT, to make it easier to examine static code that uses accesses via the GOT pointer. There will be no dynamic segment or section in a static binary to get the GOT pointer (DT_PLTGOT) from, so use section headers to find a `.got' section instead. binutils/ * readelf.c (process_mips_specific): Add static GOT support.

readelf: Don't error on .debug files with NOBITS .dynamic section. The fix for PR binutils/17512 added a check for the dynamic segment being inside the actual ELF file. If not an error message would be produced: readelf: Error: the dynamic segment offset + size exceeds the size of the file Unfortunately for separate debuginfo files it is common for the dynamic segment not being inside the file because the .dynamic section is NOBITS. Since the check is done unconditionally in process_program_headers and process_program_headers is always called (to setup dynamic_addr in case it is needed). The error is produced on any operations done on any .debug file (even if no program headers or the dynamic segment is used). If there are section headers then a cross check is done to see if the .dynamic section is NOBITS in which case dynamic_addr is set to zero without a warning or error (which is then checked first before any operation on the dynamic segement is done). Move the check for the dynamic segment being inside the actual ELF file after the cross check with the section headers to suppress the error for .debug files. binutils/ChangeLog: * readelf.c (process_program_headers): Move dynamic_addr check after .dynamic section cross check.

readelf: Correct version flag formatting Remove a trailing space or a leading pipe character from version flags printed with `readelf --version-info'. For example with the `mips-linux' target we get: $ cat ver_def.s .data .globl new_foo .type new_foo, %object new_foo: .symver new_foo, foo@@ver_foo $ cat ver_def.ver { global: *foo*; local: *; }; $ as -o ver_def.o ver_def.s $ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o $ readelf -V ver_def Version symbols section '.gnu.version' contains 4 entries: Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym) 000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo) Version definition section '.gnu.version_d' contains 2 entries: Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr) 000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def 0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo $ which includes an unnecessary space after `BASE'; both call sites already provide suitable separation from output that follows.

readelf: Fix incorrect "Version definition past end of section" message Fix a commit 74e1a04b9787 ("More fixes for reading corrupt ELF files.") `readelf --version-info' regression that caused "Version definition past end of section" to be always printed at the end, even with good section data. For example with the `mips-linux' target we get: $ cat ver_def.s .data .globl new_foo .type new_foo, %object new_foo: .symver new_foo, foo@@ver_foo $ cat ver_def.ver { global: *foo*; local: *; }; $ as -o ver_def.o ver_def.s $ ld -e 0 --export-dynamic --version-script=ver_def.ver -o ver_def ver_def.o $ readelf -V ver_def Version symbols section '.gnu.version' contains 4 entries: Addr: 000000000000007e Offset: 0x01007e Link: 2 (.dynsym) 000: 0 (*local*) 2 (ver_foo) 1 (*global*) 2 (ver_foo) Version definition section '.gnu.version_d' contains 2 entries: Addr: 0x0000000000000088 Offset: 0x010088 Link: 3 (.dynstr) 000000: Rev: 1 Flags: BASE Index: 1 Cnt: 1 Name: ver_def 0x001c: Rev: 1 Flags: none Index: 2 Cnt: 1 Name: ver_foo Version definition past end of section $ The cause is the `if (idx + ent.vd_next <= idx)' condition introduced to ensure forward progress, which however always triggers for good version definition section data as the last entry will have its `vd_next' value set to 0. Adjust the condition then, to say `if (idx + ent.vd_next < idx)' instead and to ensure forward progress limit the number of entries processed to the size of the version definition section, removing the problematic message from output quoted above, while ensuring the original PR 17531 test case is still handled gracefully. Add a suitable test case so that we have `readelf --version-info' coverage; due to the lack of infrastructure needed to run the linker in the `binutils' test suite and limited justification to implement it add a new `readelf.exp' script to the `ld' test suite instead, intended to gather any `readelf' test cases that require the linker to be run. If ever we decide to have linker infrastructure added to the `binutils' test suite, then the script can be moved between the test suites. binutils/ * readelf.c (process_version_sections) <SHT_GNU_verdef>: Limit the number of entries processed by the section size.

objdump: Better objdump section headers in wide mode When displaying the section headers table using objdump (-h), the column containing the section header name is currently fixed at 13 characters. A section name that is longer than 13 characters will overflow the column causing the table to become miss-aligned. In this commit I change the behaviour so that _in wide mode_ (-w -h) the section name column is dynamically resized to fit the longest section name we plan to display. In wide mode the column still retains a minimum width of 13 characters. In non-wide more the behaviour is completely unchanged. While I was changing the dump_headers function I have unified the two printf lines that handled the different address widths into a single printf, the address width is now passed into printf using the '*' field width format character. binutils/ChangeLog: * objdump.c (dump_section_header): Extract max section name length from data parameter, use this when formatting output. (find_longest_section_name): New function. (dump_headers): Calculate longest section name when in wide mode, reformat to unify printing of header line. ld/ChangeLog: * testsuite/ld-elf/eh-frame-hdr.d: Update expected results.
