Hi!
I have done 3 sparc builds this morning and this is the result of that.
BTW, Andreas, can you please recompute:
Failure: Test: atan2 (-0.00756827042671106339, -.001792735857538728036) == -1.80338464113663849327153994380
Result:
is: -1.80338464113663849327e+00 -0x1.cdaa9da7ca620c5349dcp+0
should be: -1.80338464113663849327e+00 -0x1.cdaa9da7ca620c5349dcp+0
difference: 3.60900012278724126504e-30 0x1.24cc0000000000000000p-98
ulp : 18739.0000
max.ulp : 0.0000
with additional precision? This is something I haven't included in
libm-test-ulps patch, as that is not atan2 ldbl-128 bug, but testcase.
30 digits aren't enough, all other numbers have at least 36. Thanks.

* sysdeps/unix/sysv/linux/sparc/sparc32/clone.S (__clone): Add support
for NPTL where the PID is stored at userlevel and needs to be reset
when CLONE_THREAD is not used.
* sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h
(SYSCALL_ERROR_HANDLER): If RTLD_PRIVATE_ERRNO, use rtld_errno
instead of errno.
* sysdeps/unix/sysv/linux/sparc/sparc64/socket.S: Include
sysdep-cancel.h instead of sysdep.h. Handle cancellation.
* sysdeps/sparc/sparc64/fpu/libm-test-ulps: Regenerate.
* sysdeps/ieee754/ldbl-128/e_expl.c: Include stdlib.h.
nptl/
* sysdeps/unix/sysv/linux/sparc/sparc32/clone.S: New file.
* sysdeps/sparc/tcb-offsets.sym: Add TID.
