2022-11-15bfd: linker: merge .sframe sectionsIndu Bhagat1-0/+1
The linker merges all the input .sframe sections. When merging, the linker verifies that all the input .sframe sections have the same abi/arch. The linker uses libsframe library to perform key actions on the .sframe sections - decode, read, and create output data. This implies buildsystem changes to make and install libsframe before libbfd. The linker places the output .sframe section in a new segment of its own: PT_GNU_SFRAME. A new segment is not added, however, if the generated .sframe section is empty. When a section is discarded from the final link, the corresponding entries in the .sframe section for those functions are also deleted. The linker sorts the SFrame FDEs on start address by default and sets the SFRAME_F_FDE_SORTED flag in the .sframe section. This patch also adds support for generation of SFrame unwind information for the .plt* sections on x86_64. SFrame unwind info is generated for IBT enabled PLT, lazy/non-lazy PLT. The existing linker option --no-ld-generated-unwind-info has been adapted to include the control of whether .sframe unwind information will be generated for the linker generated sections like PLT. Changes to the linker script have been made as necessary.

2022-11-15libsframe: add the SFrame libraryWeimin Pan2-0/+3
libsframe is a library that allows you to: - decode a .sframe section - probe and inspect a .sframe section - encode (and eventually write) a .sframe section. This library is currently being used by the linker, readelf, objdump. This library will also be used by the SFrame unwinder which is still to be upstream'd. The file include/sframe-api.h defines the user-facing APIs for decoding, encoding and probing .sframe sections. A set of error codes together with their error message strings are also defined. Endian flipping is performed automatically at read and write time, if cross-endianness is detected.

2022-11-07configure: require libzstd >= 1.4.0Christophe Lyon1-10/+10
gas uses ZSTD_compressStream2 which is only available with libzstd >= 1.4.0, leading to build errors when an older version is installed. This patch updates the check libzstd presence to check its version is >= 1.4.0. However, since gas seems to be the only component requiring such a recent version this may imply that we disable ZSTD support for all components although some would still benefit from an older version. I ran 'autoreconf -f' in all directories containing a configure.ac file, using vanilla autoconf-2.69 and automake-1.15.1. I noticed several errors from autoheader in readline, as well as warnings in intl, but they are unrelated to this patch. This should fix some of the buildbots. OK for trunk? Thanks, Christophe

2022-11-01opcodes/arm: add disassembler styling for armAndrew Burgess1-2/+2
This commit adds disassembler styling for the ARM architecture. The ARM disassembler is driven by several instruction tables, e.g. cde_opcodes, coprocessor_opcodes, neon_opcodes, etc The type for elements in each table can vary, but they all have one thing in common, a 'const char *assembler' field. This field contains a string that describes the assembler syntax of the instruction. Embedded within that assembler syntax are various escape characters, prefixed with a '%'. Here's an example of a very simple instruction from the arm_opcodes table: "pld\t%a" The '%a' indicates a particular type of operand, the function print_insn_arm processes the arm_opcodes table, and includes a switch statement that handles the '%a' operand, and takes care of printing the correct value for that instruction operand. It is worth noting that there are many print_* functions, each function handles a single *_opcodes table, and includes its own switch statement for operand handling. As a result, every *_opcodes table uses a different mapping for the operand escape sequences. This means that '%a' might print an address for one *_opcodes table, but in a different *_opcodes table '%a' might print a register operand. Notice as well that in our example above, the instruction mnemonic 'pld' is embedded within the assembler string. Some instructions also include comments within the assembler string, for example, also from the arm_opcodes table: "nop\t\t\t@ (mov r0, r0)" here, everything after the '@' is a comment that is displayed at the end of the instruction disassembly. The next complexity is that the meaning of some escape sequences is not necessarily fixed. Consider these two examples from arm_opcodes: "ldrex%c\tr%12-15d, [%16-19R]" "setpan\t#%9-9d" Here, the '%d' escape is used with a bitfield modifier, '%12-15d' in the first instruction, and '%9-9d' in the second instruction, but, both of these are the '%d' escape. However, in the first instruction, the '%d' is used to print a register number, notice the 'r' immediately before the '%d'. In the second instruction the '%d' is used to print an immediate, notice the '#' just before the '%d'. We have two problems here, first, the '%d' needs to know if it should use register style or immediate style, and secondly, the 'r' and '#' characters also need to be styled appropriately. The final thing we must consider is that some escape codes result in more than just a single operand being printed, for example, the '%q' operand as used in arm_opcodes ends up calling arm_decode_shift, which can print a register name, a shift type, and a shift amount, this could end up using register, sub-mnemonic, and immediate styles, as well as the text style for things like ',' between the different parts. I propose a three layer approach to adding styling: (1) Basic state machine: When we start printing an instruction we should maintain the idea of a 'base_style'. Every character from the assembler string will be printed using the base_style. The base_style will start as mnemonic, as each instruction starts with an instruction mnemonic. When we encounter the first '\t' character, the base_style will change to text. When we encounter the first '@' the base_style will change to comment_start. This simple state machine ensures that for simple instructions the basic parts, except for the operands themselves, will be printed in the correct style. (2) Simple operand styling: For operands that only have a single meaning, or which expand to multiple parts, all of which have a consistent meaning, then I will simply update the operand printing code to print the operand with the correct style. This will cover a large number of the operands, and is the most consistent with how styling has been added to previous architectures. (3) New styling syntax in assembler strings: For cases like the '%d' that I describe above, I propose adding a new extension to the assembler syntax. This extension will allow me to temporarily change the base_style. Operands like '%d', will then print using the base_style rather than using a fixed style. Here are the two examples from above that use '%d', updated with the new syntax extension: "ldrex%c\t%{R:r%12-15d%}, [%16-19R]" "setpan\t%{I:#%9-9d%}" The syntax has the general form '%{X:....%}' where the 'X' character changes to indicate a different style. In the first instruction I use '%{R:...%}' to change base_style to the register style, and in the second '%{I:...%}' changes base_style to immediate style. Notice that the 'r' and '#' characters are included within the new style group, this ensures that these characters are printed with the correct style rather than as text. The function decode_base_style maps from character to style. I've included a character for each style for completeness, though only a small number of styles are currently used. I have updated arm-dis.c to the above scheme, and checked all of the tests in gas/testsuite/gas/arm/, and the styling looks reasonable. There are no regressions on the ARM gas/binutils/ld tests that I can see, so I don't believe I've changed the output layout at all. There were two binutils tests for which I needed to force the disassembler styling off. I can't guarantee that I've not missed some untested corners of the disassembler, or that I might have just missed some incorrectly styled output when reviewing the test results, but I don't believe I've introduced any changes that could break the disassembler - the worst should be some aspect is not styled correctly.

2022-10-30Pool section entries for DWP version 1Alan Modra1-49/+41
Ref: https://gcc.gnu.org/wiki/DebugFissionDWP?action=recall&rev=3 Fuzzers have found a weakness in the code stashing pool section entries. With random nonsensical values in the index entries (rather than each index pointing to its own set distinct from other sets), it's possible to overflow the space allocated, losing the NULL terminator. Without a terminator, find_section_in_set can run off the end of the shndx_pool buffer. Fix this by scanning the pool directly. binutils/ * dwarf.c (add_shndx_to_cu_tu_entry): Delete range check.

2022-10-14e200 LSP supportAlan Modra1-4/+5
It has bothered me for a long time that we have disabled LSP (and SPE) tests. Also the LSP test comment indicating there is something wrong with get_powerpc_dialect. I don't think there is. Decoding of a VLE instruction depends on whether the processor is in VLE mode (some processors support both VLE and standard PPC) which we flag per section with SHF_PPC_VLE for decoding when disassembling. Background: Some versions of powerpc e200 have "Lightweight Signal Processing" support, examples being e200z215 and e200z425. As far as I can tell, LSP and SPE are mutually exclusive. This seems to be borne out by insn encoding, for example LSP "zvaddih" and SPE "evaddw" have the same encoding. So none of the processor descriptions in ppc_opts ought to have both PPC_OPCODE_LSP and PPC_OPCODE_SPE/2, if we want disassembly to work. I also could not find anything to suggest that the LSP insns are enabled only in VLE mode, which means the LSP insns should not be in vle_opcodes. Fix all this by moving the LSP insns to their own table, and add a new e200z2 cpu entry with LSP support, removing LSP from -me200z4 and from -mvle. (Yes, I know, as I said above some of the e200z4 processors have LSP. Others have SPE. It's hard to choose good options. Think of z2 as meaning earlier, z4 as later.)

This patch fixes bare invocation of egrep within binutils, replacing it with the autoconf $EGREP or with grep. config/ * lib-ld.m4 (AC_LIB_PROG_LD_GNU): Require AC_PROG_EGREP and invoke $EGREP.

2022-09-26binutils, gdb: support zstd compressed debug sectionsFangrui Song9-16/+217
PR29397 PR29563: Add new configure option --with-zstd which defaults to auto. If pkgconfig/libzstd.pc is found, define HAVE_ZSTD and support zstd compressed debug sections for most tools. * bfd: for addr2line, objdump --dwarf, gdb, etc * gas: support --compress-debug-sections=zstd * ld: support ELFCOMPRESS_ZSTD input and --compress-debug-sections=zstd * objcopy: support ELFCOMPRESS_ZSTD input for --decompress-debug-sections and --compress-debug-sections=zstd * gdb: support ELFCOMPRESS_ZSTD input. The bfd change references zstd symbols, so gdb has to link against -lzstd in this patch. If zstd is not supported, ELFCOMPRESS_ZSTD input triggers an error. We can avoid HAVE_ZSTD if binutils-gdb imports zstd/ like zlib/, but this is too heavyweight, so don't do it for now. ``` % ld/ld-new a.o ld/ld-new: a.o: section .debug_abbrev is compressed with zstd, but BFD is not built with zstd support ... % ld/ld-new a.o --compress-debug-sections=zstd ld/ld-new: --compress-debug-sections=zstd: ld is not built with zstd support % binutils/objcopy --compress-debug-sections=zstd a.o b.o binutils/objcopy: --compress-debug-sections=zstd: binutils is not built with zstd support % binutils/objcopy b.o --decompress-debug-sections binutils/objcopy: zstd.o: section .debug_abbrev is compressed with zstd, but BFD is not built with zstd support ... ```
2022-09-26binutils/testsuite: handle the different install names of c++filtClément Chigot1-1/+4
c++filt is always named cxxfilt in a build directory, but in a install directory it would be named either cxxfilt or c++filt (depending on the host). Handle this last case in testsuite. binutils/ChangeLog: * testsuite/config/default.exp (CXXFILE): if cxxfilt not found, try c++filt.

When launching the testsuite through runtest outside the build tree, gentestdlls might not be available, this binary being created by make check. Simply untested the related tests instead of crashing. binutils/ChangeLog: * testsuite/binutils-all/objdump.exp: Skip dotnet tests if gentestdlls is not available.
2022-09-26PKG_CHECK_MODULES for msgpack and janssonAlan Modra2-24/+12
Using AS_IF rather than shell "if" is recommended for conditionals that contain non-trivial autoconf macros, because autoconf will emit any AC_REQUIREd autoconf macro expansions outside of the conditional. This makes them available elsewhere in the configure script. binutils/ * configure.ac (msgpack): Use "AS_IF" rather than "if". * configure: Regenerate. ld/ * configure.ac (jansson): Use "AS_IF" rather than "if". * configure: Regenerate.

2022-09-15bfd, binutils, gas: Remove/mark unused variablesTsukasa OI1-3/+1
Clang generates a warning on unused (technically, written but not read thereafter) variables. By the default configuration (with "-Werror"), it causes a build failure (unless "--disable-werror" is specified). This commit adds ATTRIBUTE_UNUSED attribute to some of them, which means they are *possibly* unused (can be used but no warnings occur when unused) and removes others. bfd/ChangeLog: * elf32-lm32.c (lm32_elf_size_dynamic_sections): Mark unused rgot_count variable. * elf32-nds32.c (elf32_nds32_unify_relax_group): Remove unused count variable. * mmo.c (mmo_scan): Mark unused lineno variable. binutils/ChangeLog: * windmc.c (write_rc): Remove unused i variable. gas/ChangeLog: * config/tc-riscv.c (riscv_ip): Remove unused argnum variable. ld/ChangeLog: * pe-dll.c (generate_reloc): Remove unused bi and page_count variables.

2022-09-14bfd: Stop using -Wstack-usage=262144 when built with ClangTsukasa OI1-0/+18
Some components of GNU Binutils will pass "-Wstack-usage=262144" when "GCC >= 5.0" is detected. However, Clang does not support "-Wstack-usage", despite that related configuration part in bfd/warning.m4 handles the latest Clang (15.0.0 as of this writing) as "GCC >= 5.0". The option "-Wstack-usage" was ignored when the first version of Clang is released but even this "ignoring" behavior is removed before Clang 4.0.0. So, if we give Clang "-Wstack-usage=262144", it generates a warning, making the build failure. This commit checks "__clang__" macro to prevent adding the option if the compiler is identified as Clang. bfd/ChangeLog: * warning.m4: Stop appending "-Wstack-usage=262144" option when compiled with Clang. * configure: Regenerate. binutils/ChangeLog: * configure: Regenerate. gas/ChangeLog: * configure: Regenerate. gold/ChangeLog: * configure: Regenerate. gprof/ChangeLog: * configure: Regenerate. ld/ChangeLog: * configure: Regenerate. opcodes/ChangeLog: * configure: Regenerate.
