Under test/math/, there is libm-test-ulps-generic used as fallback
in case that libm-test-ulps-$(TARGET_ARCH) does not exist.
This is required for arches that don't have ULPS yet.

Native GDB requires elf_fpregset_t to be defined, even if floating point
registers are absent. In this case we use empty structure. Additionally we
redefined prfpregset_t to use this new type.
And there has been an error: it was defined that user_regs_struct has 20
registers, while it has 40.

As Will noticed, the header this check is currently done in

This breaks compilation when compiled for a Thumb2-aware CPU.

The ULPs format in glibc has changed slightly and now deviates from
that in uClibc, so when using the files directly from glibc, for
certain types of tests the ULPs values were incorrectly defaulting to
0 rather than using the values provided. This caused some tests to
fail despite the max ULPs being correctly marked.
Regenerated and updated part of the ULPs file to fix this issue. This
also added values for exp and log.

These should have been protected by
if (_dl_debug_reloc && _dl_debug_detail)
, but since the previous change "ldso/mips: actually print results of
each relocation" makes this redundant, just eliminate these prints
instead. I think this is the only item that is still printing
regardless of the value of LD_DEBUG when uClibc is built with
SUPPORT_LD_DEBUG=y.

Patch "LT.old: Make __errno_location/__h_errno_location thread safe"
uncovered yet another bug with static linking and errno (hopefully this
is last of them all).
Currently, __errno_location is declared weak but is defined strong.
While this provides with the desired weak semantics in dso, it
is subtly broken in static links.
Quoting Joern Rennecke (ARC gcc expert):
| I think the issue is that you declare the function as weak in the
| header file. That is a rare instance where you want the reference
| use declaration that differs a bit from the definition.
| If the reference uses a weakly declared function, that creates a
| weakref, i.e. the linker won't bother to look for this symbol at
| all - if it gets linked in for some other reason, fine,
| otherwise, it stays zero.
So the solution to declare strong, define weak.
Supporting data
-----------------
orig code: ARM mmap wrapper (LT.old build + my prev patch for errno)
_mmap:
@ args = 8, pretend = 0, frame = 0
@ frame_needed = 0, uses_anonymous_args = 0
stmfd sp!, {r4, r5, r7, lr}
ldr r5, [sp, #20]
movs ip, r5, asl #20
beq .L2
bl __errno_location(PLT)
mov r3, #22
str r3, [r0, #0]
mvn r0, #0
...
...
.weak __errno_location
A statically linked hello world program which uses mmap too.
As we can see__errno_location is completely gone - which is
semantically wrong - we need functional errno.
00008274 <__GI_mmap>:
8274: e92d40b0 push {r4, r5, r7, lr}
8278: e59d5014 ldr r5, [sp, #20]
827c: e1b0ca05 lsls ip, r5, #20

828c: e5803000 str r3, [r0]
8290: e3e00000 mvn r0, #0
This in turn is due to a fixup in ARM ld which transforms branch-to-null
into a nop. It is better than crashing but still wrong since errno
handling is removed.
With the patch, errno_location is restored back in test program.

WHY: errno in uClibc is not thread safe
HOW: __errno_location and it's sibling __h_errno_location need to be called
via PLT - even from within libc. That way when linked with pthread,
intra-uClibc callers will also use the thread safe version.
This is achieved by removing the GI alias for these functions,
ensuring that they get called normally (via PLT)
Verified with ARC LT.old and ARM cubieboard2 buildroot (LT.old)
NPTL is unaffected by this bug.
------------ History behind this patch ---------------------
This is a long standing bug (https://bugs.busybox.net/show_bug.cgi?id=2089)
Others have tried to fix it in past (alteast Peter Korsgaard's patch in 2010),
but somehow failed to be merged (or were backed out afterwards).
http://lists.uclibc.org/pipermail/uclibc/2010-July/044176.html
One of the causes could be side effect of atleast one more bug related to
pthreads and static link which has now been fixed.
http://lists.uclibc.org/pipermail/uclibc/2013-October/047958.html
I have solved this w/o looking at other pacthes but would like to give
credit to Peter and others for confirming that it makes sense.

If the dynamic linker is built with LDSO_STANDALONE_SUPPORT=y, it can
load then run a dynamically linked program when explicitly invoked
from the command line. This is used for test and prelink purposes,
and also by other tools like PRoot to force the kernel to load the
right ELF interpreter.
This feature is currently broken on x86_64 since the number of command
line arguments (ie. argc) passed from the kernel is an "elf_addr_t"
(64 bit on x86_64), whereas it is read as an "unsigned int" (32 bit on
x86_64).

This patch fixes the rest of the set-but-not-used warnings in the MIPS
code by using attribute_unused and also fixes some conversion warnings
by changing __arch_compare_and_exchange_xxx_[8|16]_int. Assigning __cmp
(int type) to __prev (pointer type) generates a warning. Assigning zero
to each separately avoids this warning without having to add a cast.

The INLINE_SYSCALL, INTERNAL_SYSCALL*, and internal_syscall* macros
are defined for MIPS in both libc/sysdeps/linux/mips/sysdep.h and
libc/sysdeps/linux/mips/bits/syscalls.h. The macros are the same
in both cases except that syscalls.h defines internal_syscalls[567]
the same for N32 and N64 ABIs and has a different definition for O32.
I believe that is correct. The sysdep.h header uses the O32 versions
for N32 and has different definitions for N64. I think that is wrong
and that N32 and N64 should share the same definition (modulo the
type 'long' vs. 'long long' for the arguments. This setup (from
sysdep.h) now agrees with what glibc has.
I am not positive about which header (sysdep.h vs syscalls.h) is
really the right one to have these definitions in but using sysdep.h
seems to work for all my builds.

The special sync_file_range handling is only needed for the O32 ABI
(regardless of whether it is on mips32 or mips64). The N32 (and N64)
ABI's should both use the standard code. This routine was using the
special code for the N32 ABI because that ABI has a word size of 32 bits
and that is wrong. This patch fixes it by checking the ABI used instead
of checking the word size.

When booting a Linux system with qemu-system-mips64 the execution
of $(pwd) in the ash shell triggers a segmentation fault. Ash uses
setjmp/longjmp for exception handling.
After looking at the glibc implementation,
I found some differences, with this patch tries to resolve.
Now the system boots up fine and no segmentation faults occur.
The global pointer should be restored and the types for the
register values should be wide enough.
