* Add LDPT_REGISTER_CLAIM_FILE_HOOK_V2 linker plugin hook [GCC PR109128]Joseph Myers2023-05-112-6/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is one part of the fix for GCC PR109128, along with a corresponding GCC change. Without this patch, what happens in the linker, when an unused object in a .a file has offload data, is that elf_link_is_defined_archive_symbol calls bfd_link_plugin_object_p, which ends up calling the plugin's claim_file_handler, which then records the object as one with offload data. That is, the linker never decides to use the object in the first place, but use of this _p interface (called as part of trying to decide whether to use the object) results in the plugin deciding to use its offload data (and a consequent mismatch in the offload data present at runtime). The new hook allows the linker plugin to distinguish calls to claim_file_handler that know the object is being used by the linker (from ldmain.c:add_archive_element), from calls that don't know it's being used by the linker (from elf_link_is_defined_archive_symbol); in the latter case, the plugin should avoid recording the object as one with offload data. bfd/ * plugin.c (struct plugin_list_entry): Add claim_file_v2.

* Generated docs and include filesAlan Modra2023-05-0329-2219/+2456
| | | | | | | | | | | | | bfd/doc/chew.c extracts documentation from source code comments annotated with keywords, and generates much of bfd.h and libbfd.h from those same comments. The docs have suffered from people (me too) adding things like CODE_FRAGMENT to the source to put code into bfd.h without realising that CODE_FRAGMENT also puts @example around said code into the docs. So we have random senseless things in the docs. This patch fixes that problem (well, the senseless things from CODE_FRAGMENT), moves most of the code out of bfd-in.h, and improves a few chew.c features. libbfd.h now automatically gets ATTRIBUTE_HIDDEN prototypes, and indentation in bfd.h and libbfd.h is better.

* RISC-V: Support XVentanaCondOps extensionPhilipp Tomsich2023-04-261-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ventana Micro has published the specification for their XVentanaCondOps ("conditional ops") extension at https://github.com/ventanamicro/ventana-custom-extensions/releases/download/v1.0.0/ventana-custom-extensions-v1.0.0.pdf which contains two new instructions - vt.maskc - vt.maskcn that can be used in constructing branchless sequences for various conditional-arithmetic, conditional-logical, and conditional-select operations. To support such vendor-defined instructions in the mainline binutils, this change also adds a riscv_supported_vendor_x_ext secondary dispatch table (but also keeps the behaviour of allowing any unknow X-extension to be specified in addition to the known ones from this table). As discussed, this change already includes the planned/agreed future requirements for X-extensions (which are likely to be captured in the riscv-toolchain-conventions repository): - a public specification document is available (see above) and is referenced from the gas-documentation - the naming follows chapter 27 of the RISC-V ISA specification - instructions are prefixed by a vendor-prefix (vt for Ventana) to ensure that they neither conflict with future standard extensions nor clash with other vendors bfd/ChangeLog: * elfxx-riscv.c (riscv_get_default_ext_version): Add riscv_supported_vendor_x_ext.
