            Bug ID: 20723
           Summary: Static linking fails on Haswell and Sandy Bridge
           Product: glibc
           Version: 2.24
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: rlcamp.pdx at gmail dot com
  Target Milestone: ---

The math library in the newest glibc in both Ubuntu 16.10 (2.24-3ubuntu1) and
Debian-testing (2.24-3) cannot be statically linked successfully on Haswell or
Sandy Bridge (when compiling with -static and -march=native, -march=haswell, or
-march-sandybridge). The specific errors are "undefined reference to
_ZGVcN4v_cos" and similar at link time. The problem does not occur when not
statically linking, and does not occur when using -march=nehalem or some other
pre-AVX instruction set. The problem does not occur when using musl-libc rather
than glibc.
