2021-05-11dwarf.c (process_abbrev_set): Properly parenthesize, fix falloutHans-Peter Nilsson2-1/+6

To wit, the (non-cast) term abbrev_size is a dwarf_vma and causes the whole expression to (still) be 64 bits. binutils: * dwarf.c (process_abbrev_set): Properly parenthesize before casting to unsigned long.

2021-05-10Avoid possible pointer wrapAlan Modra2-3/+9
PTR supplied to these macros can be read from user input, END is an end of buffer pointer. It's safer to do arithmetic on END than on PTR. * dwarf.c (SAFE_BYTE_GET): Check bounds by subtracting amount from END rather than adding amount to PTR. (SAFE_SIGNED_BYTE_GET, SAFE_BYTE_GET64): Likewise.
2021-05-09Use htab_eq_string in binutilsAlan Modra2-9/+7
A quick check says this is the only place in all of bfd, opcodes, binutils, gas, ld, gprof that duplicates the new libiberty htab_eq_string. * objcopy.c (eq_string): Delete. (create_symbol_htab): Use htab_eq_string.
2021-05-08binutils: update release docs processMike Frysinger2-16/+26
Now that we generate multiple html & pdf forms, update the release process to show how they get updated.
2021-05-08support generating multi-html pages in parallelMike Frysinger3-2/+17
Use the pattern from other projects where we generate the html pages in a dir named the same as the project. So now we have: gas/doc/gas.html - single html page gas/doc/gas/ - multiple html pages This works for projects that have a doc/ subdir already, but gprof & ld require a little tweaking since they generate their docs in their respective toplevels.
2021-05-08generate single html manual page by defaultMike Frysinger3-2/+9
This better matches other GNU projects like autoconf/automake where the html manual is the single page form. We'll support the multi-page form in a follow up change.

2021-03-29TRUE/FALSE simplificationAlan Modra5-8/+17
There is really no need to write code like "foo != 0 ? TRUE : FALSE" unless we had stupidly defined FALSE as something other than 0 or TRUE as something other than 1. The simpler "foo != 0" does just as well. Similarly "(condition == TRUE)" or "(condition == FALSE) can be simplified to "(condition)" and "(!condition)" respectively. I'll note that there is reason to use "integer_expression != 0" when assigning a bfd_boolean rather than the simpler "integer_expression", if you expect the variable to have 0 or 1 value. It's probably even a good idea to not rely on implicit conversion if bfd_boolean were _Bool. bfd/ * aoutx.h (aout_link_write_symbols): Don't cast boolean expression to bfd_boolean. * elf32-or1k.c (or1k_set_got_and_rela_sizes): Dont compare booleans against FALSE. * elf32-arc.c (name_for_global_symbol): Don't compare boolean to TRUE.

Since the last time AIX HOWTO table was modified, IBM has now released an official documentation about XCOFF relocations. This commit corrects the wrong ones and add some missing. For now, the "custom" relocations made for xcoff_rtype2howto have been kept. The new relocations are still set as EMPTY_HOWTO because they will be implemented in later commits.

2021-03-05bfd/binutils: add support for RISC-V CSRs in core filesAndrew Burgess2-0/+7
Adds support for including RISC-V control and status registers into core files. The value for the define NT_RISCV_CSR is set to 0x900, this corresponds to a patch I have proposed for the Linux kernel here: http://lists.infradead.org/pipermail/linux-riscv/2020-December/003910.html As I have not yet heard if the above patch will be accepted into the kernel or not I have set the note name string to "GDB", and the note type to NT_RISCV_CSR. This means that if the above patch is rejected from the kernel, and the note type number 0x900 is assigned to some other note type, we will still be able to distinguish between the GDB produced NT_RISCV_CSR, and the kernel produced notes, where the name would be set to "CORE". bfd/ChangeLog: * elf-bfd.h (elfcore_write_riscv_csr): Declare. * elf.c (elfcore_grok_riscv_csr): New function.

2021-03-05bfd/binutils: support for gdb target descriptions in the core fileAndrew Burgess2-0/+7
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.
