            Bug ID: 81934
           Summary: after install of 7.2.0 the libcilkrts.la has extra
                    quote chars in it for dependency_libs
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dclarke at blastwave dot org
  Target Milestone: ---

After installation of gcc 7.2.0 there exists two libtool "dot-la" files both
named libcilkrts.la but for 32-bit and 64-bit as this is sparc. 

Thus : 

    /usr/local/gcc7/lib/libcilkrts.la
        and
    /usr/local/gcc7/lib/sparcv9/libcilkrts.la

They both have extra single quote chars inside the dependency_libs value 
and had to be manually scrubbed out : 

# diff ./gcc7/lib/libcilkrts.la /usr/local/gcc7/lib/libcilkrts.la
20c20
< dependency_libs=' -lpthread /usr/local/gcc7/lib/libstdc++.la'
---
> dependency_libs=' -lpthread '/usr/local/gcc7/lib'/libstdc++.la'

# diff gcc7/lib/sparcv9/libcilkrts.la /usr/local/gcc7/lib/sparcv9/libcilkrts.la
20c20
< dependency_libs=' -lpthread /usr/local/gcc7/lib/sparcv9/libstdc++.la'
---
> dependency_libs=' -lpthread '/usr/local/gcc7/lib/sparcv9'/libstdc++.la'

Not sure how they ended up in there but all the other .la type files seem
fine.

Also, for this bug there is no clear component for "install" and I can not
choose "no component" so I randomly took "tree-optimization".
That will need to be fixed most likely.
