[Bug target/58797] New: Expand __builtin_copysignl inline for powerpc soft-float/e500v1


http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58797

            Bug ID: 58797
           Summary: Expand __builtin_copysignl inline for powerpc
                    soft-float/e500v1
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jsm28 at gcc dot gnu.org
            Target: powerpc*-*-linux*

The powerpc port should have an insn pattern for copysigntf3 for soft-float and
e500v1; right now, the complex multiplication/division in libgcc ends up with
an undefined reference to copysignl in those configurations.  This doesn't
generally cause problems for glibc users - glibc has copysignl in libc as well
as libm - but can trip up users of other C libraries.
