2022-09-06bfd: Add bfd_find_nearest_line_with_altAaron Merey1-0/+49
bfd_find_nearest_line_with_alt functions like bfd_find_nearest_line with the addition of a parameter for specifying the filename of a supplementary debug file such as one referenced by .gnu_debugaltlink or .debug_sup. This patch focuses on implementing bfd_find_nearest_line_with_alt support for ELF/DWARF2 .gnu_debugaltlink. For other targets this function simply sets the invalid_operation bfd_error.

2022-03-16bfd: add AMDGCN architectureSimon Marchi1-0/+21
Add support for the AMDGCN architecture to BFD. This is the bare minimum to get $ ./configure --target=amdgcn-hsa-amdhsa --disable-gas $ make all-binutils working later in this series. The specific AMDGCN models added here are a bit arbitrary, based on what we intend to initially support in GDB. This list will need to be updated in the future anyway. The complete up-to-date list of existing AMDGPU models can be found here: https://llvm.org/docs/AMDGPUUsage.html#processors The ELF format for this architecture is documented here: https://llvm.org/docs/AMDGPUUsage.html#elf-code-object The flags for the "HSA" OS ABI are properly versioned and documented on that page. But the NONE, PAL and MESA3D OS ABIs are not well documented nor versioned. Taking a peek at the LLVM source code, we see that they encode their flags the same way as HSA v3. For example, for PAL: https://github.com/llvm/llvm-project/blob/c8b614cd74a92d85936aed5ac7c642af75ffdc29/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp#L601 So at least, we know that all AMDGPU objects (of which AMDGCN objects are a subset of) at the time of writing encode the specific GPU model in the EF_AMDGPU_MACH field of e_flags. bfd/ChangeLog: * Makefile.am (ALL_MACHINES, ALL_MACHINES_CFILES): Add cpu-amdgcn.c.

2022-02-02or1k: Avoid R_OR1K_GOT16 signed overflow by using special howtoStafford Horne1-0/+7
Previously when fixing PR 21464 we masked out upper bits of the relocation value in order to avoid overflow complaints when acceptable. It turns out this does not work when the relocation value ends up being signed. To fix this this patch introduces a special howto with complain_on_overflow set to complain_overflow_dont. This is used in place of the normal R_OR1K_GOT16 howto when we detect R_OR1K_GOT_AHI16 relocations. bfd/ChangeLog: PR 28735 * elf32-or1k.c (or1k_elf_got16_no_overflow_howto): Define.
