            Bug ID: 20750
           Summary: Build fails with default PIE enabled gcc-6.x
           Product: glibc
           Version: 2.24
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: build
          Assignee: unassigned at sourceware dot org
          Reporter: allan at archlinux dot org
                CC: carlos at redhat dot com
  Target Milestone: ---

When using a gcc-6.x built with --enable-debug-pie, glibc-2.24 fails to compile
with errors in the form:

../sysdeps/x86_64/multiarch/memcpy-ssse3.S: Assembler messages:
../sysdeps/x86_64/multiarch/memcpy-ssse3.S:65: Error: operand type mismatch for
`jb'

This occurs in several of the mem* related assembly files.

Reverting commit 6901def6 ("Avoid an extra branch to PLT for -z now") allows
the build to complete.
