riastradh | t_rtld_r_debug: Test this as a non-PIE executable too.
On MIPS, non-PIEs can use DT_MIPS_RLD_MAP or DT_MIPS_RLD_MAP_REL,
while PIEs can't use DT_MIPS_RLD_MAP because it relies on an absolute
virtual address baked into the file. So it's important to test both.

riastradh | tests/libexec/ld.elf_so/t_ifunc: Handle MKRELRO=no.
Just build t_ifunc and t_ifunc_now normally. If they wind up being
built with the same options as t_ifunc_norelro and
t_ifunc_norelro_now, so be it; easier to do it this way than to put
more conditionals into set lists.

Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. This
functions are used for destructors of thread_local objects.
If a pending destructor exists, prevent unloading of shared objects.
Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.
Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.

joerg | branches: 1.8.8;
Add basic support for indirect functions. It allows providing a public
function symbol with an implementation choosen at run time.
Refactor calls to functions by address in ld.elf_so to create temporary
function descriptors on the stack, if the address is not leaked outside.
Limitations:
- no support for initialising static storage with function pointers
- no support for unnamed resolver functions
Inspired by FreeBSD's r228435 by kib@freebsd.org.

The SysV ABI specifies that the symbol hash function should return only 32
bits of hash. Unfortunately due to an implementation bu and the fact that
the return type is unsigned long which is 64 bits in LP64, this can fail
in some cases: "\xff\x0f\x0f\x0f\x0f\x0f\x12". See:

ld.elf_so: New test for extern initial-exec TLS, PR toolchain/50277.
ld.elf_so: Fix extern TLS test to match PR toolchain/50277.
Now it's actually testing the problem.
ld.elf_so: Nix inadvertently committed private test program.
ld.elf_so: Fix set lists for MKDEBUG=yes builds with t_tls_extern.
ld.elf_so: Sprinkle tls debug messages.
ld.elf_so: Make tls alloc debug messages more detailed and greppable.
ld.elf_so: Test variations on PR toolchain/50277.
ld.elf_so: Test extern dynamic TLS too.
ld.elf_so: Factor out logic in TLS tests to make writing more easier.
No functional change intended.
ld.elf_so: Test TLS abuse of static def, dynamic use and vice versa.
ld.elf_so: Shorter test names.
No functional non-cosmetic change intended.
ld.elf_so: Separately test eager and lazy resolution of def tls ptr.
eager: before loading use library
lazy: after loading use library
Add recent ld.elf_so test helpers debug info
ld.elf_so: Add new files to debug/shl.mi.
ld.elf_so: tls_extern dynamic_defabuse_eager must xfail differently.
If a symbol has already been resolved as dynamic TLS, any library
that tries to use it as static TLS cannot be dlopened.
ld.elf_so: Test another edge case of mismatched TLS models.
One library defines a symbol and _doesn't_ use it, so it has no
indication of whether the symbol is for static TLS or dynamic TLS,
and then two other libraries use it in different ways.
ld.elf_so: Test dynamic-then-static abuse via ctor.
ld.elf_so: Fix missing tab in debug/shl.mi in last change.
Fix interactions of initial-exec TLS model and dlopen
(1) If an initial-exec relocation was used for a non-local symbol
(i.e. the definition of the symbol is in a different DSO), the
computation of the static TLS offset used the wrong DSO.
This would effectively mean the wrong address was computed
(PR toolchain/50277, PR pkg/57445).
Fix this by forcing the computation of the correct DSO (the one defining
the symbol).
This code uses __UNCONST to avoid the vast interface changes for this
special case.
(2) If symbols from a DSO loaded via dlopen are used with both
global-dynamic/local-dynamic and initial-exec relocations AND
a initial-exec relocation was resolved first in a thread, a split brain
situation could exist where the dynamic relocations would use one memory
block (separate allocation) and the initial-exec relocations the static
per-thread TLS space.
(3) If the initial-exec relocation in (2) is seen after any thread has
already used a GD/LD allocation, bail out. Since IE relocations are used
only in the GOT, this will prevent the dlopen. This is a bit more
aggressive than necessary, but a full blown reference counting doesn't
seem to be justified.
Avoid using uninitialized variable "symnum" when building with DEBUG
enabled by borrowing the rdbg_symname() macro from arch/x86_64.
ld.elf_so: Sprinkle more debug messages on dlopen and error.
PR pkg/57445
Fix MKDEBUGLIB build by adding these installed files to the debug
set list.
One could argue that these files are not of any use, so why install
them? I don't have a good argument either way, and this is (for
now) a simple work-around for PR bin/57455 Please feel free to
commit a different fix to avoid installing these files at all.
Fix markup of libh_ MKDEBUGLIB=yes only files
TLS variant I archs need to fudge the offset by the size of the TCB.
tests/libexec/ld.elf_so: Fix helper library makefiles.
1. Consolidate logic into a single helper.mk to reduce duplication.
2. Set NO* variables, not MK* variables which are reserved for user.
3. Avoid eager X!= in favour of lazy ${X:sh}.
4. Mark _g.a set list entries obsolete. Never should've been built!

The SysV ABI specifies that the symbol hash function should return only 32
bits of hash. Unfortunately due to an implementation bug and the fact that
the return type is unsigned long which is 64 bits in LP64, this can fail
in some cases: "\xff\x0f\x0f\x0f\x0f\x0f\x12". See:
