Subject: visibility-[1-9a].c: Change to use scan-hidden instead of scan-assembler.
X-Git-Tag: releases/gcc-4.0.0~3591
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d533f1cb17580dea7f45d6ff7a1a371b796556e3;p=thirdparty%2Fgcc.git

visibility-[1-9a].c: Change to use scan-hidden instead of scan-assembler.

2004-10-28  Andrew Pinski  <pinskia@physics.uc.edu>

        * gcc.dg/visibility-[1-9a].c: Change to use scan-hidden instead of
        scan-assembler.
        * lib/scanasm.exp (hidden-scan-for): New proc.
        (scan-hidden): Use hidden-scan-for instead of constructing the scan
        string.
        (scan-not-hidden): Likewise.
        * lib/target-supports.exp (check_visibility_available): mach-o is
        support too.
