FreeBSD's kernel has recently added two new ELF auxiliary vector
entries to describe the location of the user stack for the initial
thread in a process.
This change displays the proper name and description of these entries
in 'info auxv'.
This patch support ZTSO extension. It will turn on the tso flag for elf_flags
once we have enabled Ztso extension. This is intended to implement v0.1 of
the proposed specification which can be found in Chapter 25 of,
https://github.com/riscv/riscv-isa-manual/releases/download/draft-20220723-10eea63/riscv-spec.pdf.

They were legacy relocation types copied from other ports. The related

The associated assembler directives (.vtable_inherit and .vtable_entry)
have never been supported by the RISC-V port. Remove related ld code.

The Linux kernel can dump memory tag segments to a core file, one segment
per mapped range. The format and documentation can be found in the Linux
kernel tree [1].
The following patch adjusts bfd and binutils so they can handle this new
segment type and display it accordingly. It also adds code required so GDB
can properly read/dump core file data containing memory tags.
Upon reading, each segment that contains memory tags gets mapped to a
section named "memtag". These sections will be used by GDB to lookup the tag
data. There can be multiple such sections with the same name, and they are not
numbered to simplify GDB's handling and lookup.
There is another patch for GDB that enables both reading
and dumping of memory tag segments.
Tested on aarch64-linux Ubuntu 20.04.
[1] Documentation/arm64/memory-tagging-extension.rst (Core Dump Support)
Commit 04f096fb9e ("Move the xc16x target to the obsolete list") moved
the architecture from the "obsolete but still available" to the
"obsolete / support removed" list in config.bfd, making the architecture
impossible to enable (except maybe via "enable everything" options").
Note that I didn't touch */po/*.po{,t} on the assumption that these
would be updated by some (half)automatic means.
Requiring C99 means that uses of bfd_uint64_t can be replaced with
uint64_t, and similarly for bfd_int64_t, BFD_HOST_U_64_BIT, and
BFD_HOST_64_BIT. This patch does that, removes #ifdef BFD_HOST_*
and tidies a few places that print 64-bit values.
This core dump note contains the value of the base address of the %fs
and %gs segments for both i386 and amd64 core dumps. It is primarily
useful in resolving the address of TLS variables in core dumps.

Decode and print the AMDGPU-specific fields of e_flags, as documented
here:
https://llvm.org/docs/AMDGPUUsage.html#header
That is:
- The specific GPU model
- Whether the xnack and sramecc features are enabled
The result looks like:
- Flags: 0x52f
+ Flags: 0x52f, gfx906, xnack any, sramecc any
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:
c8b614cd74/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp (L601)
So for those other OS ABIs, we read them the same as HSA v3.

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

c8b614cd74/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.

FreeBSD's kernel has recently added two new ELF auxiliary vector
entries. AT_FXRNG points to a root seed version for the kernel's
PRNG. Userland can use this to reseed a userland PRNG after the
kernel's PRNG has reseeded. AT_KPRELOAD is the base address of a
kernel-provided vDSO.
This change displays the proper name and description of these entries
in 'info auxv'.

This is the original discussion,

And here is the glibc part,
https://sourceware.org/pipermail/libc-alpha/2021-August/129931.html
For binutils part, we need to support a new direcitve: .variant_cc.
The function symbol marked by .variant_cc means it need to be resolved
directly without resolver for dynamic linker. We also add a new dynamic
entry, STO_RISCV_VARIANT_CC, to indicate there are symbols with the
special attribute in the dynamic symbol table of the object.
I heard that llvm already have supported this in their mainline, so
I think it's time to commit this.
bfd/
* elfnn-riscv.c (riscv_elf_link_hash_table): Added variant_cc
flag. It is used to check if relocations for variant CC symbols
may be present.

flag, then raise the variant_cc flag of riscv_elf_link_hash_table.

R_PPC64_REL24_P9NOTOC is a variant of R_PPC64_REL24_NOTOC for use on
@notoc cals from non-power10 code in the rare case that using such a
construct is useful. R_PPC64_REL24_P9NOTOC will be emitted by gas
rather than R_PPC64_REL24_NOTOC when @notoc is used in a branch
instruction if power10 instructions are not enabled at that point.
The new relocation tells the linker to not use power10 instructions on
any stub emitted for that branch, unless overridden by
--power10-stubs=yes.
The current linker heuristic of only generating power10 instructions
for stubs if power10-only relocations are detected, continues to be
used.
