Bug ID: 16545
Summary: Test failures: small differences in float/double y0,
etc.
Product: glibc
Version: 2.19
Status: NEW
Severity: minor
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: dylan-sourceware at dylex dot net
Created attachment 7399
--> http://sourceware.org/bugzilla/attachment.cgi?id=7399&action=edit
cat test-{,i}{double,float}.out
Linux x86_64 3.12.6, gcc 4.8.2, AMD Opteron(tm) Processor 4274 HE, glibc 2.19
I'm seeing failures in the test-float, -double, -ifloat, -idouble tests
producing very small differences (fractional errors at most 1e-7) on my
machine. No major discrepencies or issues, but I would've expected these to
pass. Perhaps caused by minor gcc or processor differences?

Please run "make regen-ulps", move the NewUlps file into place and send the
diffs to libc-alpha. These tests depend on the implementation of x87
transcendental math instructions on the processor, and on the compiler's choice
of when to use excess precision.

I've attached the diffs here and will also send them to the list. This is for
AMD family 21h model 1.

Fix checked in (though it will be useful to do regen-ulps again when we start
the 2.20 release freeze).
