[COMMITTED] Regenerate sparc ULPs.

* sysdeps/sparc/fpu/libm-test-ulps: Update.
---

This doesn't fix all the ULP issues during the testsuite on sparc,
some are not accepted by the maximum ULP limits encoded into libm-test.inc

For example, for test-float and test-ifloat y1_upward gets a ULP of 10,
and for test-ldouble and test-ildoubl y1_upward gets a ULP of 10 and
y1_downward gets a ULP of 13.

I see that we use an upper limit of 13 for IBM long double in the
inexact cases... should we use something similar for 128-bit IEEE
cases as well?

Hi,

on s390 test-ldouble / test-ildoubl shows the same ULP for y1(0x2p+0)
(see https://www.sourceware.org/ml/libc-alpha/2014-04/msg00271.html).

Please test the posted patch.

Bye.

Yep, it clears the long-double cases for me.

I still have a large ULP of 10 for test-float's y1_upward().

No.  That increased limit is an allowance for IBM long double not being an 
IEEE type and the underlying arithmetic operations having errors of up to 
3 ulps.  If you get larger errors for an IEEE type, the implementations of 
the relevant libm functions should be fixed to reduce error accumulation.

I'm going to guess that this doesn't appear on x86_64 because of the 
x86_64 implementation of trig functions using double precision internally 
so having smaller error accumulation than the generic flt-32 versions.  
Saving / restoring the rounding mode in y1f would seem a reasonable 
solution.

Ok, right now it's just y1_upward() giving me an error of 10 ULPs for
float.

I'll look into this, thanks Joseph.
