2023-01-19Correct coff-aarch64 howtos and delete unnecessary special functionsAlan Modra1-157/+44
The remaining special functions are still broken except when called by gas bfd_install_relocation. * coff-aarch64.c (coff_aarch64_addr64_reloc), (coff_aarch64_addr32_reloc, coff_aarch64_branch26_reloc), (coff_aarch64_branch19_reloc, coff_aarch64_branch14_reloc), (coff_aarch64_po12a_reloc): Delete. (HOWTO_INSTALL_ADDEND): Define as 1. (HOW): Remove pcrel_off. Correct all the howtos. (CALC_ADDEND): Define. (coff_aarch64_rtype_to_howto): New function. (coff_rtype_to_howto): Define.
2023-01-19coff-aarch64.c howtosAlan Modra1-67/+56
This is just a patch to fix overlong lines. Wrapping the HOWTO macro in a new HOW macro helps in this. No functional changes here. * coff-aarch64.c (HOW): Define and use for reloc howtos.
2023-01-19howto install_addendAlan Modra2-231/+67
This adds a new flag to the reloc howtos that can be used to incrementally change targets over to simple bfd_install_relocation that just installs the addend without any weird adjustments. I've made a few other changes to bfd_install_relocation, removing dead code and comments that are really only applicable to bfd_perform_relocation. There is also a reloc offset bounds check change. I've moved the check to where data is accessed, as it seems reasonable to me to not perform the check unless it is needed. There is precedence for this; Relocations against absolute symbols already avoided the check. I also tried always performing the reloc offset check, and ran into testsuite failures due to _NONE and _ALIGN relocs at the end of sections. These likely would be fixed if all such reloc howtos had size set to zero, but I would rather not edit lots of files when it involves checking that target code does not use the size. * reloc.c (struct reloc_howto_struct): Add install_addend. (HOWTO_INSTALL_ADDEND): Define. (HOWTO): Init new field with HOWTO_INSTALL_ADDEND. (bfd_install_relocation): Remove comments copied from bfd_perform_relocation that aren't applicable here. Remove code dealing with output_offset and output_section. Just set relocation to addend if install_addend. Move reloc offset bounds check to just before section data is accessed, avoiding the check when data is not accessed. * bfd-in2.h: Regenerate.

2023-01-18Use subsystem to distinguish between pei-arm-little and pei-arm-wince-littleMark Harmstone2-0/+17
Running objdump against a 32-bit ARM PE file currently needs disambiguation, as it gets picked up by both pei-arm-little and pei-arm-wince-little. This adds a check in pe_bfd_object_p so that the subsystem in the PE header is used to do the disambiguation for us, so that WinCE images get assigned to pei-arm-wince-little, and everything else to pei-arm-little.

2023-01-12ARM: Fix ld bloat introduced between binutils-2.38 and 2.39Hans-Peter Nilsson1-4/+0
Since commit 9833b7757d24, "PR28824, relro security issues", ELF_MAXPAGESIZE matters much more, with regards to layout of the linked file. That commit fixed an actual bug, but also exposes a problem for targets were that value is too high. For example, for ARM(32, a.k.a. "Aarch32") specifically bfd_arch_arm, it's set to 64 KiB, making all Linux(/GNU) targets pay an extra amount of up to 60 KiB of bloat in DSO:s and executables. This matters when there are many such files, and where storage is expensive. It's *mostly* bloat when using a Linux kernel, as ARM(32) is a good example of an target where ELF_MAXPAGESIZE is set to an extreme value for an obscure corner-case. The ARM (32-bit) kernel has 4 KiB pages, has had that value forever, and can't be configured to any other value. The use-case is IIUC "Aarch32" emulation on an "Aarch64" (arm64) kernel, but not just that, but a setup where the Linux page-size is configured to something other than the *default* 4 KiB. Not sure there actually any such systems in use, again with both Aarch32 compatibility support and a non-4KiB pagesize, with all the warnings in the kernel config and requiring the "EXPERT" level set on. So, let's do like x86-64 in a2267dbfc9e1 "x86-64: Use only one default max-page-size" and set ELF_MAXPAGESIZE to 4096. bfd: * elf32-arm.c (ELF_MAXPAGESIZE): Always set to 0x1000.
2023-01-12Use __func__ rather than __FUNCTION__Alan Modra5-8/+7
We already use C99's __func__ in places, use it more generally. This patch doesn't change uses in the testsuite. I've also left one in gold.h that is protected by GCC_VERSION < 4003.

2023-01-10Add aarch64-w64-mingw32 targetMark Harmstone2-3/+3
This adds a mingw target for aarch64, including windres and dlltool. Note that the old value of jmp_aarch64_bytes was wrong, and this does the same thing as MSVC does.
2023-01-10Add .secrel32 for pe-aarch64Mark Harmstone1-1/+46
Adds the .secrel32 pseudo-directive and its corresponding relocation.
2023-01-10Add pe-aarch64 relocationsMark Harmstone2-20/+660
This adds the remaining pe-aarch64 relocations, and gets them working. It also brings in the constant directives from ELF, as otherwise .word would be 2 rather than 4 bytes, and .xword and .dword wouldn't be defined.
2023-01-10Fix size of external_reloc for pe-aarch64Mark Harmstone1-4/+0
This patch series finishes off the work by Jedidiah Thompson, and adds support for creating aarch64 PE images. This should be essentially complete: I've used this to create a "hello world" Windows program in asm, and (with GCC patches) a UEFI program in C. I think the only things missing are the .secidx relocation, which is needed for PDBs, and the SEH pseudos used for C++ exceptions. This first patch fixes the size of RELSZ; I'm not sure why it was 14 in the first place. This is the size of the "Base Relocation Block" in https://learn.microsoft.com/en-us/windows/win32/debug/pe-format, and AFAIK should be 10 for everything.

2023-01-10Re: Move bfd_init to bfd.cAlan Modra3-44/+44
Commit b1c95bc4dd73 resulted in ...bfd.texi:246: @include: could not find init.texi which went unnoticed due to not building in a clean directory. This fixes the problem by moving bfd_init earlier, giving it a doc node, and stitching the nodes back together. * bfd.c (bfd_init): Move earlier. Give it a doc inode. Adjust other inodes to suit. * doc/bfd.texi: Don't include init.texi. Adjust nodes to suit.

This fixes a memory leak in the vanishingly rare cases (found by fuzzers of course) when something goes wrong in the save_section_vma, htab_create_alloc or alloc_trie_leaf calls before *pinfo is written. If *pinfo is not written, _bfd_dwarf2_cleanup_debug_info won't be able to free that memory. * dwarf2.c (_bfd_dwarf2_slurp_debug_info): Save stash pointer on setting up stash.
2023-01-10peXXigen.c sanity checksAlan Modra1-44/+52
Also fix a memory leak, and make some style changes. I tend to read (sizeof * x) as a multiplication of two variables, which I would not do if binutils followed the gcc coding conventions consistently (see https://gcc.gnu.org/codingconventions.html#Expressions). (sizeof *x) looks a lot better to me, or even (sizeof (*x)) which I've used here. * peXXigen.c (get_contents_sanity_check): New function. (pe_print_idata): Use it here.. (pe_print_edata): ..and here.

2023-01-10Move bfd_init to bfd.cAlan Modra7-60/+56
init.c contains just one function that doesn't do much. Move it to bfd.c and give it something to do, initialising static state. So far the only initialisation is for bfd.c static variables. The idea behind reinitialising state is to see whether some set of flaky oss-fuzz crashes go away. oss-fuzz stresses binutils in ways that can't occur in reality, feeding multiple testcases into the internals of binutils. So one testcase may affect the result of the next testcase. * init.c: Delete file. Move bfd_init to.. * bfd.c (bfd_init): ..here. Init static variables. * Makefile.am (BFD32_LIBS): Remove init.lo. (BFD32_LIBS_CFILES, BFD_H_FILES): Remove init.c. * doc/local.mk: Remove mention of init.texi and init.c. * Makefile.in: Regenerate. * bfd-in2.h: Regenerate. * po/SRC-POTFILES.in: Regenerate.

2023-01-06Make coff backend data read-onlyAlan Modra6-34/+56
The bfd_coff_backend_data struct should be read-only, the only thing preventing this is that objcopy writes to one of the fields, _bfd_coff_long_section_names. This patch creates a copy of the field in bfd coff_obj_tdata, which makes more sense anyway. When enabling long section names the intent is to do so for a particular bfd, not for all bfds that might happen to be using the target xvec. bfd/ * coffcode.h: Update coff long section name comment.
