            Bug ID: 60599
           Summary: [4.9 Regression] Testsuite's scan-module-absence no
                    longer works
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org

The test suite moved to zipped files. That broke the implicit_pure*f90 test
cases, which use, e.g.,

! { dg-final { scan-module-absence "m" "IMPLICIT_PURE" } }


That function defined in gcc/testsuite/lib/gcc-dg.exp:

    set modfilename [string tolower [lindex $args 0]].mod
    set fd [open $modfilename r]
    set text [read $fd]
    close $fd

That code obviously fails when the file is zipped.

Note that scan-module in the same file contains a "gzip" to handle this case.
