            Bug ID: 57651
           Summary: [4.8 / 4.9 Regression] gcc-ar and gcc-nm don't find
                    the lto plugin
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: doko at gcc dot gnu.org

$ gcc-ar-4.8 -h
gcc-ar-4.8: Cannot find plugin 'liblto_plugin.so'

the plugin is *not* installed with x permission flags (which seems to be the
standard for shared libraries).   You did change the code to use find_a_file
which searches only for files with the x bit set.

Work around is to install the plugin with the x bits set, or use some helper
function which doesn't look for the x bits.  I assume that wasn't catched,
because the plugin then was found in another location?

gcc.c has a static find_a_file function which does allows to specify the
permission flags you want to search for.

now, working around the permission bit, I get:

$ gcc-ar-4.8
gcc-ar-4.8: Cannot find binary 'ar'

so it only searches ar in the given paths, not on the path of the file system
(/usr/bin in this case)

please lets fix it in gcc.  I fixed it in gcc.c last year, and this behaviour
is now re-introduced, so it is a regression.  shared libraries work without the
x bit set too, so lets just recognize these too.

Matthias, I see where you already have a proposed patch here:
