[Bug ports/15666] New: alpha missing __sqrt*_finite


http://sourceware.org/bugzilla/show_bug.cgi?id=15666

            Bug ID: 15666
           Summary: alpha missing __sqrt*_finite
           Product: glibc
           Version: 2.17
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ports
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org
                CC: carlos at redhat dot com, roland at gnu dot org, rth at gcc dot gnu.org
              Host: alpha*-*

The alpha libm.abilist is missing __sqrt{,f,l}_finite.

It appears the alpha-specific sqrt implementations are missing those aliases. 
They should be added - of course at a new symbol version specific to alpha,
since they weren't in fact in 2.15 as they were for other architectures.  But
there's a complication that it appears __sqrt{,f}_finite would have been
present already for builds not using the sysdeps/alpha/alphaev6 directory.  So
if building without that directory does indeed work, I suppose you need to
provide compat symbols for those two at GLIBC_2.15, for compatibility with any
binaries built against such a glibc, in addition to having all three at a new
version such as GLIBC_2.18.
