H.J. Lu fff53daefb i386/x86-64: Add unwind info for .plt.got section
When there are both PLT and GOT references to the same function symbol,
linker combines GOTPLT and GOT slots into a single GOT slot and create
an entry in .plt.got section for PLT access via the GOT slot.  This
patch adds unwind info for .plt.got section.

Graham Markall 07ccf83cf5 [ARC] Add new linker emulation for nps
The arc700 nps variant uses some specific named sections to
facilitate its CMEM based instructions, which operate on memory
regions fixed at specific addresses.

This commit adds the arclinux_nps emulation, which is based on the
arclinux emulation. The new emulation uses the OTHER_SECTIONS
variable in the emulation parameters script to provide symbols
mapping to various locations in the CMEM space on nps.

The accompanying test ensures that all symbols are provided at the
correct address in the linker script.

  * Makefile.am: Add earclinux_nps.c target and add to
  ALL_EMULATION_SOURCES.
  * Makefile.in: Likewise, regenerated.

Palmer Dabbelt 6ec11ab97a Remove some custom sections from RISC-V's default linker scripts
This was added so compressed loads could have smaller offsets for
accessing the data section, but the result was that writable sections
ended up in INITIAL_READONLY_SECTIONS.  This is a bad idea.  The fix is
to just remove this micro-optimization.

Thanks to Alan Morda for finding the problem!

Alan Modra d981640286 Run more ld tests when not native
Many of the ld tests are not run for cross builds, in some cases
because the test needs to run a newly linked executable, and in others
simply because it was easier to write the test for native only.  Even
when a test needs to run, it's good to compile and link to exercise
the linker.  So that's what this patch does.  I've also rid us of
the old ld_link procedure with all the HOSTING_CRT0 etc. setup.  It's
much simpler to just link with $CC.

This does mean that a cross build with cross-compiler installed but
no cross C-library will give lots of failures.  If that turns out to
be too annoying, I guess we can write a tcl procedure to detect it and
not run all the extra tests.

Alan Modra 5474d94f03 dynrelro section for read-only dynamic symbols copied into executable
Variables defined in shared libraries are copied into an executable's
.bss section when code in the executable is non-PIC and thus would
require dynamic text relocations to access the variable directly in
the shared library.  Recent x86 toolchains also copy variables into
the executable to gain a small speed improvement.

The problem is that if the variable was originally read-only, the copy
in .bss is writable, potentially opening a security hole.  This patch
cures that problem by putting the copy in a section that becomes
read-only after ld.so relocation, provided -z relro is in force.

The patch also fixes a microblaze linker segfault on attempting to
use dynamic bss variables.

Yury Norov c1fc2d7ee5 ld: aarch64: fix TLS relaxation where TCB_SIZE is used
TCB_SIZE is 2*sizeof(void *), which is 0x10 for lp64, and 0x8 for
ilp32. During relaxation, ld goes to do a replace:
bl   __tls_get_addr => add R0, R0, TCB_SIZE

But actual implementation is:
bfd_putl32 (0x91004000, contents + rel->r_offset + 4);

Which is equivalent of add x0, x0, 0x10. This is wrong for ilp32.

The possible fix for it is:
bfd_putl32 (0x91000000 | (TCB_SIZE<<10), contents + rel->r_offset + 4);

But ilp32 also needs w-registers, so it's simpler to put proper
instruction in #if/#else condition.

There are 2 such relaxations in elfNN_aarch64_tls_relax(), and so 2 new
tests added for ilp32 mode to test it.

RX does horrible fudges to PT_LOAD p_vaddr, that affect the testsuite

probably doesn't matter too much since RX is an embedded target, but
it's easy to stop some of the fudges in order to reduce special cases

Alan Modra 8c5b4e5228 PowerPC64 dot-symbol compatibility bugfixes
Lots of fixes for the compatibility code that handles linking of
-mcall-aixdesc code (or that generated by 12 year old gcc) with
current ELFv1 ABI code.

1) A reference to a dot-symbol in an object file wasn't satisfied by a
   function descriptor in later object files.
2) The as-needed code had bit-rotted;  Shared libs now need a strong
   reference to be counted as needed.
3) --gc-sections involving dot-symbols was broken, needing
   func_desc_adjust to be run early and lots of other fixes.
