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.
