Commit 04f096fb9e25 ("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.

Add a -z pack-relative-relocs option to enable DT_RELR and create a
relr.dyn section for DT_RELR. DT_RELR is implemented with the linker
relaxation infrastructure, but it doesn't require the --relax option
enabled. -z pack-relative-relocs implies -z combreloc. -z nocombreloc
implies -z nopack-relative-relocs.
-z pack-relative-relocs is chosen over the similar option in lld,
--pack-dyn-relocs=relr, to implement a glibc binary lockout mechanism
with a special glibc version symbol, to avoid random crashes of DT_RELR
binaries with the existing glibc binaries.

My commit 261980de18b added alignment for the resource table symbol.
But it is wrong. The Linux remoteproc driver loads and interprets the
contents of the .resource_table ELF section, not of a table symbol.
Without this patch, if the linker happens to output padding for symbol
alignment, then the resource table contents as viewed by the kernel
loader would "shift" and look corrupted.

* scripttempl/pru.sc (.resource_table): Align the output
section, not the first symbol.

Add support for TLS in XCOFF. Amongst the things done by this commit:
- Update XCOFF auxialiary header to match new version and allow TLS
sections.
- Add TLS sections (.tdata and .tbss) support in gas and ld.
- Add support for the TLS relocations in gas and ld.
Two different types BFD_RELOC are created for PPC and PPC64 as
the size is a pointer, thus distinct in 32 or 64bit.
The addresses given by ld to .tdata and .tbss is a bit special. In
XCOFF, these addresses are actually offsets from the TLS pointer
computed at runtime. AIX assembly and linker does the same. In
top of that, the .tdata must be before .data (this is mandatory for AIX
loader). Thus, the aix ld script is recomputing "." before .data to restore
its original value. There might be a simpler way, but this one is working.
Optimisation linked to TLS relocations aren't yet implemented.

The offset-within-section field in the symbol table entry is only 32
bits wide, so rather than emitting bogus entries omit them, and issue
a diagnostic identifying the issue.
This requires adjusting the PR/22267 test to no longer produce symbols
with out of range values on 64-bit BFD. This also depends on
adjustments to testsuite/ld-scripts/map-address.* made by an earlier
patch. The purpose of the test can very well be achieved nevertheless.

__{preinit,init,fini}_array_start symbols must be word aligned in
linker scripts. If the section preceding the __*_array_start symbol
has an odd size, then a NULL byte will be present between the start
symbol and the .*_array section itself, when the section gets
automatically word-aligned.
This results in a branch to an invalid address when the CRT startup
code tries to run through the functions listed in the array sections.
Some MSP430 linker scripts do not align the __*_array start symbols, so
this added warning will catch that problem and help the user avoid
the potential incorrect execution of the program.

With this patch, ld/pr24511 test passes for ARC.
At first glance, the test was failing because the order of
"__init_array_start" and "__fini_array_start" weak symbols were
reversed:
$ nm -n dump.out
expected output | real output
00002104 D __init_array_start | 00002104 D __fini_array_start
0000210c D __fini_array_start | 00002104 D __init_array_start
The order of the symbols are different as a side effect of both
symbols being mapped to the _same_ address (0x2104). Looking
further into the mapping logs [1] revealed that the linker
script must consider all instances of ".init_array" (in other
words ".init_array.*") inside its relevant section. Same logic
holds for ".fini_array".
Therefore, adding "KEEP (*(SORT(.init_array.*)))" to the linker
script, along with the one for ".finit_array.*", resolved the
problem. While at it, I took the liberty of refactoring the
script a little bit and made those pieces of script macros.

So, here's my suggestion for making _init .. __etext cover .text +
.rodata (including things like the read-only exception tables) for
elf64mmix. A quick web search gives that __etext (and friends) isn't
well defined, so each target can interpret the "end of text segment"
to their own liking. It seems likely this change is also a better fit
than the default for other ports, at least those with .rodata after
.text in the same segment.
The presence of a separate rodata-segment is optional (and not true
for elf64mmix). This is reflected in the name as SEPARATE_TEXT /
SEPARATE_CODE isn't considered, to keep it simple; each target has to
make sure their settings of variables make sense.

This both makes the section layout more similar to that of the general
default for ELF and fixes (makes true) an assumption that code and
rodata is located between _init and __etext, in
libgcc/config/mmix/crti.S. Sadly, that's not actually true for ELF
(generally and for elf64mmix), where exception-tables and .rodata is
after _etext; I'm pondering what to do about that.
The original mmix simulator behavior is that memory magically appears
on access, initialized with 0, which is not preferable when chasing
bugs by throwing code the size of the gcc test-suite to the simulator.
The code in crti.S compatibly enables simulator machinery to identify
undefined memory and instead stopping the simulator with an error
(going to interactive mode for interactive runs). See
http://gcc.gnu.org/legacy-ml/gcc-patches/2012-10/msg01871.html for
more, including the mmix-sim.ch "patch file".
This fixes only one error in the gcc testsuite,
gcc.c-torture/execute/pr20621-1.c with LTO, where for some reason
gcc/lto chooses to move (writable) data that is only used to read 0 to
.rodata. An access (sufficiently far inside a block) in an
unregistered place is flagged as an invalid access.
The bpo-9m test that I had to adjust, actually exposes a wart: mmo
does not have the notion of symbol types (or sections) and the
test-case now has leading zeros at "Main" eventually leading to it
being misdiagnosed as being outside .text and .data, thus here mapped
to BFD as an absolute symbol. The test is not intended to check the
mmo symbol-type machinery, so I'm just tweaking it to be
symbol-type-neutral for "Main".
Since you have to jump through hoops to see the problem, I don't think
this commit is worth putting on the 2.35-branch.

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.

This patch makes the elf64bpf emulation to use it's own linker script,
based on elf.sc. At the moment, the only change is that the BPF
executable doesn't define an entry symbol (BPF programs feature
several entry points scattered in several sections.)
This is a step towards the goal of generating proper ELF executables
that would be loaded by the kernel's libbpf. We are not there yet:
BPF "programs" should still be linked with -r.
This change removes a warning while linking executables, decreases the
number of unsupported tests in the target from 47 to 29, and increases
the number of expected passes from 104 to 145.
Regtested in x86_64 for all targets.
No regressions.

2019-08-07 Jose E. Marchesi <jose.marchesi@oracle.com>
* scripttempl/elf64bpf.sc: Adapted from elf.sc.

__rel[a]_iplt_start and __rel[a]_iplt_end are defined to handle IFUNC in
static executables. For PIE, since IFUNC is handled as the part of the
normal dynamic relocation processing, there is no need to define these
symbols in PIE.
* scripttempl/elf.sc (CREATE_PIC): New. Set for CREATE_SHLIB or
CREATE_PIE.
(__rel_iplt_start): Don't define for CREATE_PIC.

(__rela_iplt_end): Likewise.

The special case for .init and .fini in update_wild_statements is
ineffective for .init or .fini wildcards inside other output sections.
The special case needs to be on the wildcard, not the output section.
This patch is belt and braces, both fixing update_wild_statements and
the scripts.

For ld -r, we generally set the VMA of sections to zero. This is done
to make the output of ld -r most similar to that output by the
assembler, which generally has sections starting at VMA zero. In some
cases that covers for backend bugs which would mis-handle relocatable
object files with non-zero section VMAs.
This patch fixes a few sections that didn't have zero VMAs for ld -r.
A missing zero on .note.gnu.build-id and .eh_frame_hdr doesn't matter
much since these are linker generated symbols only output on final
link, but it's good to be consistent.

"ld -r" generally should not combine object file sections with
different names. For example, "ld -r" should not combine ".text",
".text.hot" and ".text.cold" into an output ".text" section. An
exception needs to be made for linker created sections, for example,
branch trampoline sections that might be created even for ld -r.
"ld -r" also should not define symbols in linker scripts. Any
definitions are likely to conflict with those defined at final link.
A MEMORY spec is also not needed for ld -r.
