2020-09-08MSP430: Support relocations for subtract expressions in .uleb128 directivesJozef Lawrynowicz1-0/+2
Link-time relaxations of branches are common for MSP430, given that GCC can generate pessimal branch instructions, and the -mcode-region=either/-mdata-region=either options to shuffle sections can further change the type of branch instruction required. These relaxations can result in invalid code when .uleb128 directives, used in the .gcc_except_table section, are used to calculate the distance between two labels. A value for the .uleb128 directive is calculated at assembly-time, and can't be updated at link-time, even if relaxation causes the distance between the labels to change. This patch adds relocations for subtract expressions in .uleb128 directives, to allow the linker to re-calculate the value of these expressions after relaxation has been performed. bfd/ChangeLog: * bfd-in2.h (bfd_reloc_code_real): Add BFD_RELOC_MSP430_{SET,SUB}_ULEB128. * elf32-msp430.c (msp430_elf_ignore_reloc): New.

2020-09-08aarch64: Add base support for Armv8-RAlex Coplan1-0/+1
This patch adds the basic infrastructure needed to support Armv8-R in AArch64 binutils: new command-line flags, new feature bits, a new BFD architecture, and support for differentiating between architecture variants in the disassembler. The new command-line options added by this patch are -march=armv8-r in GAS and -m aarch64:armv8-r in objdump. The disassembler support is necessary since Armv8-R AArch64 introduces a system register (VSCTLR_EL2) which shares an encoding with a different system register (TTBR0_EL2) in Armv8-A. This also allows us to use the correct preferred disassembly for the new DFB alias introduced in Armv8-R. bfd/ChangeLog: 2020-09-08 Alex Coplan <alex.coplan@arm.com> * archures.c (bfd_mach_aarch64_8R): New. * bfd-in2.h: Regenerate. * cpu-aarch64.c (bfd_aarch64_arch_v8_r): New.

2020-04-02coff-go32-exe: support variable-length stubsJan W. Jagersma1-3/+2
The stub size in GO32 executables has historically been fixed at 2048 bytes, due to hardcoded limitations in bfd. Recent patches to djgpp by Stas Sergeev (CC'd) have pushed the stub right up to this limit, so if any further expansion is desired, this must first be patched in bfd. This series includes three patches: The first changes the meaning of the bfd->origin field slightly, so that target code can use this to specify an offset into the file where the actual bfd is located. The second patch then uses this to enable support for variable-sized stubs in the coff-go32-exe format. The final patch is only a cleanup, it normalizes function and variable names in coff-stgo32.c so that they all begin with the same prefix. bfd * bfdio.c (bfd_bread, bfd_tell, bfd_seek, bfd_mmap): Always add bfd->origin to file offset. * bfdwin.c (bfd_get_file_window): Likewise. * bfd.c: Clarify the use of the bfd->origin field. * bfd-in2.h: Regenerate. * coff-i386.c: Don't include go32exe.h.

2020-03-02bfd_cleanup for object_pAlan Modra1-3/+5
The object_p (and archive_p, core_file_p) functions are not supposed to have any target specific malloc'd memory attached to the bfd on their return. This should be obvious on a failure return, but it's also true for a successful return. The reason is that even though the object_p recognises the file, that particular target may not be used and thus the bfd won't be closed calling close_and_cleanup for the target that allocated the memory. It turns out that the object_p bfd_target* return value isn't needed. In all cases except ld/plugin.c the target is abfd->xvec and with ld/plugin.c the target isn't used. So this patch returns a cleanup function from object_p instead, called in bfd_check_format_matches to tidy the bfd before trying a different target match. The only cleanup that does anything at this stage is the alpha-vms one. bfd/ * targets.c (bfd_cleanup): New typedef.

2020-02-06ELF: Support the section flag 'o' in .section directiveH.J. Lu1-1/+3
As shown in https://sourceware.org/bugzilla/show_bug.cgi?id=25490 --gc-sections will silently remove __patchable_function_entries section and generate corrupt result. This patch adds the section flag 'o' to .section directive: .section __patchable_function_entries,"awo",@progbits,foo .section __patchable_function_entries,"awoG",@progbits,foo,foo,comdat .section __patchable_function_entries,"awo",@progbits,bar,unique,4 .section __patchable_function_entries,"awoG",@progbits,foo,foo,comdat,unique,1 which specifies the symbol name which the section references. Assmebler will set its elf_linked_to_section to a local section where the symbol is defined.

2020-02-02ELF: Add support for unique section ID to assemblerH.J. Lu1-2/+10
Clang's integrated assembler supports multiple section with the same name: .section .text,"ax",@progbits,unique,1 nop .section .text,"ax",@progbits,unique,2 nop "unique,N" assigns the number, N, as the section ID, to a section. The valid values of the section ID are between 0 and 4294967295. It can be used to distinguish different sections with the same section name. This is useful with -fno-unique-section-names -ffunction-sections. -ffunction-sections by default generates .text.foo, .text.bar, etc. Using the same string can save lots of space in .strtab. This patch adds section_id to bfd_section and reuses the linker internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler internal use to mark valid section_id. It also updates objdump to compare section pointers if 2 sections comes from the same file since 2 different sections can have the same section name. bfd/ PR gas/25380 * bfd-in2.h: Regenerated. * ecoff.c (bfd_debug_section): Add section_id. * section.c (bfd_section): Add section_id.

2019-11-25Pass section when available to bfd_octets_per_byteAlan Modra1-1/+1
and other tidies. I think it's better to default to passing the section to bfd_octets_per_byte, even in cases where we know it won't make a difference. A number of the coff reloc functions used bfd_octets_per_byte wrongly, not factoring it into the offset into the data buffer. As it happens, the targets using those files always had bfd_octets_per_byte equal to one, so there wasn't any detectable wrong behaviour. However, it is wrong in the source and might cause trouble for anyone creating a new target.

2019-11-18PR25196, abort in rewrite_elf_program_headerAlan Modra1-0/+1
This patch introduces a new "sorry, cannot handle this file" bfd error status. The idea is to use this error in cases where bfd hasn't found a bfd_bad_value error, ie. an input file or set of options that are invalid, but rather an input file that is simply too difficult to process. Typically this might happen with fuzzed object files such as the one in the PR, a wildly improbable core file. Some things are just not worth wasting time over to fix "properly".

2019-11-07Remove CR16C supportAlan Modra1-44/+0
I think it is past time to remove CR16C support. CR16C was added in 2004, and only for ld. gas and binutils support is lacking, and there have been no commits to bfd/elf32-cr16c.c other than warning fixes or global maintainers making changes to all targets. I see no maintainer listed for CR16C, and no commits from anyone at NSC supporting the target. Furthermore, at the time the CR16 support was added in 2007, config.sub was changed upstream to no longer recognise cr16c as a valid cpu. That means the CR16C ld support is only available as a secondary target by configuring with, for example, --enable-targets=all or --enable-targets=cr16c-unknown-elf. No testing of the CR16C target is possible. include/ * elf/cr16c.h: Delete. bfd/ * cpu-cr16c.c: Delete. * elf32-cr16c.c: Delete. * Makefile.am, * archures.c, * config.bfd, * configure.ac, * reloc.c, * targets.c: Remove cr16c support. * Makefile.in, * bfd-in2.h, * configure, * libbfd.h, * po/SRC-POTFILES.in: Regenerate. ld/ * emulparams/elf32cr16c.sh: Delete. * scripttempl/elf32cr16c.sc: Delete. * Makefile.am, * configure.tgt: Remove cr16c support. * NEWS: Mention removal of cr16c. * Makefile.in, * po/BLD-POTFILES.in: Regenerate.
