elf/x86-64: Subtract __ImageBase for R_AMD64_IMAGEBASE When linking Windows x86-64 relocatable object files to generate x86-64 ELF executable, we need to subtract __ImageBase, aka __executable_start, for R_AMD64_IMAGEBASE relocation: 1. Add link_info to struct output_elf_obj_tdata to store linker info and _bfd_get_link_info() to retrieve it. 2. Add ldelf_set_output_arch to set up link_info. 3. Add pex64_link_add_symbols to create an indirect reference to __executable_start for __ImageBase to support R_AMD64_IMAGEBASE relocation when adding symbols from Windows x86-64 relocatable object files to generate x86-64 ELF executable. 4.

bfd/binutils: support for gdb target descriptions in the core file This commit lays the ground work for allowing GDB to write its target description into a generated core file. The goal of this work is to allow a user to connect to a remote target, capture a core file from within GDB, then pass the executable and core file to another user and have the user be able to examine the state of the machine without needing to connect to a running target. Different remote targets can have different register sets and this information is communicated from the target to GDB in the target description. It is possible for a user to extract the target description from GDB and pass this along with the core file so that when the core file is used the target description can be fed back into GDB, however this is not a great user experience. It would be nicer, I think, if GDB could write the target description directly into the core file, and then make use of this description when loading a core file. This commit performs the binutils/bfd side of this task, adding the boiler plate functions to access the target description from within a core file note, and reserving a new number for a note containing the target description. Later commits will extend GDB to make use of this. The new note is given the name 'GDB' and a type NT_GDB_TDESC. This should hopefully protect us if there's ever a reuse of the number assigned to NT_GDB_TDESC by some other core file producer. It should also, hopefully, make it clearer to users that this note carries GDB specific information. bfd/ChangeLog: * elf-bfd.h (elfcore_write_gdb_tdesc): Declare new function. * elf.c (elfcore_grok_gdb_tdesc): New function.

Move x86_64 PE changes out of bfd_perform_relocation bfd_perform_relocation should not have special case target code. This patch moves the code that was there for x86_64 PE linking to ELF output into the x86_64 PE howto special function, correcting that function for linking to targets other than ELF too. The fixes in bfd_perform_relocation were over-complicated due to needing to compensate for things that had already gone wrong in coff_amd64_reloc. In particular, an adjustment for pc-relative relocs was done in a way that meant adjustment for things related to symbol offsets was lost. I think those two things are orthogonal, but who knows with COFF where addends and symbol values are found randomly in the section contents. Note that linking natively to an x86_64 PE output relocates by coff_pe_amd64_relocate_section, which does not use arelent relocs or bfd_perform_relocation, but be aware of coff_amd64_rtype_to_howto hacking addends for relocations. The adjustments for a particular relocation type there and in coff_amd64_reloc ought to match after taking into consideration CALC_ADDEND. They don't. For example, the pc-relative adjustment for R_PCRWORD is 2 bytes in coff_amd64_reloc and 4 bytes in coff_amd64_rtype_to_howto. * reloc.c (bfd_perform_relocation): Revert 2021-01-12 and 2020-09-16 changes. * coff-x86_64.c (coff_amd64_reloc): Do more or less the same adjustments here instead.

bfd, ld, libctf: skip zero-refcount strings in CTF string reporting This is a tricky one. BFD, on the linker's behalf, reports symbols to libctf via the ctf_new_symbol and ctf_new_dynsym callbacks, which ultimately call ctf_link_add_linker_symbol. But while this happens after strtab offsets are finalized, it happens before the .dynstr is actually laid out, so we can't iterate over it at this stage and it is not clear what the reported symbols are actually called. So a second callback, examine_strtab, is called after the .dynstr is finalized, which calls ctf_link_add_strtab and ultimately leads to ldelf_ctf_strtab_iter_cb being called back repeatedly until the offsets of every string in the .dynstr is passed to libctf. libctf can then use this to get symbol names out of the input (which usually stores symbol types in the form of a name -> type mapping at this stage) and extract the types of those symbols, feeding them back into their final form as a 1:1 association with the real symtab's STT_OBJ and STT_FUNC symbols (with a few skipped, see ctf_symtab_skippable). This representation is compact, but has one problem: if libctf somehow gets confused about the st_type of a symbol, it'll stick an entry into the function symtypetab when it should put it into the object symtypetab, or vice versa, and *every symbol from that one on* will have the wrong CTF type because it's actually looking up the type for a different symbol. And we have just such a bug. ctf_link_add_strtab was not taking the refcounts of strings into consideration, so even strings that had been eliminated from the strtab by virtue of being in objects eliminated via --as-needed etc were being reported. This is harmful because it can lead to multiple strings with the same apparent offset, and if the last duplicate to be reported relates to an eliminated symbol, we look up the wrong symbol from the input and gets its type wrong: if it's unlucky and the eliminated symbol is also of the wrong st_type, we will end up with a corrupted symtypetab. Thankfully the wrong-st_type case is already diagnosed by a this-can-never-happen paranoid warning: CTF warning: Symbol 61a added to CTF as a function but is of type 1 or the converse * CTF warning: Symbol a3 added to CTF as a data object but is of type 2 so at least we can tell when the corruption has spread to more than one symbol's type. Skipping zero-refcounted strings is easy: teach _bfd_elf_strtab_str to skip them, and ldelf_ctf_strtab_iter_cb to loop over skipped strings until it falls off the end or finds one that isn't skipped. bfd/ChangeLog 2021-03-02 Nick Alcock <nick.alcock@oracle.com> * elf-strtab.c (_bfd_elf_strtab_str): Skip strings with zero refcount. ld/ChangeLog 2021-03-02 Nick Alcock <nick.alcock@oracle.com> * ldelfgen.c (ldelf_ctf_strtab_iter_cb): Skip zero-refcount strings. libctf/ChangeLog 2021-03-02 Nick Alcock <nick.alcock@oracle.com> * ctf-create.c (symtypetab_density): Report the symbol name as well as index in the name != object error; note the likely consequences. * ctf-link.c (ctf_link_shuffle_syms): Report the symbol index as well as name.

read_leb128 overflow checking There is a tiny error left in dwarf.c:read_leb128 after Nick fixed the signed overflow problem in code I wrote. It's to do with sleb128 values that have unnecessary excess bytes. For example, -1 is represented as 0x7f, the most efficient encoding, but also as 0xff,0x7f or 0xff,0xff,0x7f and so on. None of these sequences overflow any size signed value, but read_leb128 will report an overflow given enough excess bytes. This patch fixes that problem, and since the proper test for signed values with excess bytes can easily be adapted to also test a sleb byte with just some bits that overflow the result, I changed the code to not use signed right shifts. (The C standard ISO/IEC 9899:1999 6.5.7 says signed right shifts of negative values have an implementation defined value. A long time ago I even used a C compiler for a certain microprocessor that always did unsigned right shifts. Mind you, it is very unlikely to be compiling binutils with such a compiler.) bfd/ * wasm-module.c: Guard include of limits.h. (CHAR_BIT): Provide backup define.

RISC-V: PR27200, allow the first input non-ABI binary to be linked with any one. RISC-V only defines two float ABIs, soft-float and double-float, and the value of soft-float is 0x0. But 0x0 usually means unknown/default setting for many targets, and the non-ABI binary, which is generated by "ld/objcopy -b binary", also has the 0x0 elf header flags, this may be confused. We probably can define a new unknown/default ABI value to make them more clear, but that will need more bits in the elf header flags, and also need to discuss in the riscv psabi spec. Training linker have a default ABI setting, and can be changed by ld options or configure options is another solution, like what assemblr usually do. So all objects, including the binary files, will have explicit ABI setting. But the binary files will no longer be linked with any object, users need to recompile them with the exactly ABI they want. It may be inconvenience sometimes. Besides, I think linker doesn't need to know the default arch/abi so far, just set them according to the linked objects should be enough. Therefore, without changing the riscv psabi, and keep the non-ABI binary can be linked with any object, we don't check the ABI flags if no code section in the PR24389. Just that we find the first input non-ABI binary still cannot be linked with others in the PR27200. This patch fixs the problem by delaying the elf_flags_init(obfd) check, since the flags of non-ABI object with no code cannot be copyed to output BFD, we should skip it, even if it is the first linked object. However, there is a strange "break" at the end of loop in the PR24389. The "break" cause the ld testcase "Link with zlib-gabi compressed debug output 1" fails for rv64gc-linux toolchain, after applying the above change. The root cause is that - the "break" make linker only checks the "first" section of input BFD rather than the entire sections. I have checked that AARCH64 and ARM both have the "break" at the end of loop, but ARC doesn't. I suppose we should remove the "break" like what ARC do, or use a pair of braces for the if statement. I have passed the elf/linux toolchain regressions, so the change should be fine. bfd/ PR 27200 * elfnn-riscv.c (_bfd_riscv_elf_merge_private_bfd_data): Delay copying the elf flags from input BFD to output BFD, until we have checked if the input BFD has no code section or not.

bfd, opcodes, libctf: support --with-included-gettext Right now, these libraries hardwire -L../intl -lintl on a few fixed platforms, which works fine on those platforms but on other platforms leads to shared libraries that lack libintl_* symbols when configured --with-included-gettext, and/or static libraries that contain libintl as *another* static library. If we instead use the LIBINTL variable defined in ../intl/config.intl, this gives us the right thing on all three classes of platform (gettext in libc, gettext in system libintl, gettext in ../intl/libintl.a).. This also means we can rip out some Darwin-specific machinery from configure.ac and also simplify the Cygwin side. This also means that the libctf testsuite (and other places that include libbfd, libopcodes or libctf) don't need to grow libintl dependencies just on account of those libraries (though they still need such dependencies if they themselves use gettext machinery). bfd/ChangeLog 2021-02-03 Nick Alcock <nick.alcock@oracle.com> * configure.ac (SHARED_LIBADD): Remove explicit -lintl population in favour of LIBINTL. * configure: Regenerated. libctf/ChangeLog 2021-02-02 Nick Alcock <nick.alcock@oracle.com> * configure.ac (CTF_LIBADD): Remove explicit -lintl population in favour of LIBINTL. * Makefile.am (libctf_nobfd_la_LIBADD): No longer explicitly include $(LIBINTL).

SHF_LINK_ORDER fixup_link_order in ld This moves the SHF_LINK_ORDER sorting from bfd_elf_final_link to the linker which means generic ELF targets now support SHF_LINK_ORDER and we cope with odd cases that require resizing of output sections. The patch also fixes two bugs in the current implementation, introduced by commit cd6d537c48fa. The pattern test used by that commit meant that sections matching something like "*(.IA_64.unwind* .gnu.linkonce.ia64unw.*)" would not properly sort a mix of sections matching the two wildcards.

The BSF_SECTION_SYM_USED should be set if the section symbol is used for relocation or the section symbol is always included in the symbol table. Add keep_unused_section_symbols to bfd_target to indicate if unused section symbols should be kept. If TARGET_KEEP_UNUSED_SECTION_SYMBOLS is defined as FALSE, unused ection symbols will be removed. Tested on Linux/x86. Other ELF backends need to: 1. Define TARGET_KEEP_UNUSED_SECTION_SYMBOLS to FALSE. 2. Mark used section symbols in assembler backend. 3. Remove unused section symbols from expected assembler and linker outputs. bfd/ PR 27109 * aix386-core.c (core_aix386_vec): Initialize keep_unused_section_symbol to TARGET_KEEP_UNUSED_SECTION_SYMBOLS. * aout-target.h (MY (vec)): Likewise. * binary.c (binary_vec): Likewise. * cisco-core.c (core_cisco_be_vec): Likewise.

RISC-V: Support riscv bitmanip frozen ZBA/ZBB/ZBC instructions (v0.93). In fact rev8/orc.b/zext.h are the aliases of grevi/gorci/pack[w], so we should update them to INSN_ALIAS when we have supported their true instruction in the future. Though we still use the [MATCH|MAKS]_[GREVI|GORCI|PACK|PACKW] to encode them. Besides, the orc.b has the same encoding both in rv32 and rv64, so we just keep one of them in the opcode table.

elf: Allow mixed ordered/unordered inputs for non-relocatable link For non-relocatable link with SHF_LINK_ORDER inputs, allow mixed indirect and data inputs with ordered and unordered inputs: 1. Add pattern to bfd_section for the matching section name pattern in linker script and update BFD_FAKE_SECTION. 2. Sort the consecutive bfd_indirect_link_order sections with the same pattern to allow linker script to overdide input section order. 3. Place unordered sections before ordered sections. 4.
