            Bug ID: 22631
           Summary: [m68k] Bad const attributes in bits/mathinline.h
           Product: glibc
           Version: 2.26
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org
  Target Milestone: ---
              Host: m68k-*-*

m68k bits/mathinline.h declares various functions with const attributes.  These
are inappropriate for functions that have results depending on the rounding
mode; the machine-independent bits/mathcalls.h only uses const attributes for a
very few functions with no rounding mode dependence, and the m68k header should
do likewise.  GCC uses pure for such functions with -frounding-math, resulting
in GCC mainline warning for conflicts with between the header and the built-in
attributes and glibc failing to build for m68k with GCC mainline.
