PR/95720
When the status wrapper is used, the gluefile need to be prefixed with
-Wl, in order for the test cases to have the dump files with the
expected names.

gcc/testsuite/ChangeLog:

        * gcc/testsuite/lib/g++.exp: Moved gluefile block to after
          flags have been prefixed for the target_compile call.
        * gcc/testsuite/lib/gcc.exp: Likewise.
        * gcc/testsuite/lib/wrapper.exp: Reset adjusted state flag.

I agree this looks right, but I'm curious how you ended up with the
behaviour seen in comment 16.  I thought having:

    if { [target_info needs_status_wrapper] != "" && [info exists gluefile] } {
	lappend options "libs=${gluefile}"
	lappend options "ldflags=${wrap_flags}"
    }

before the dg-additional-files-options/gcc_adjusted_linker_flags would
lead to the gluefile missing a "-Wl," first time round.  How is it that
the gluefile still gets the "-Wl," and the -T misses it instead?

Thanks,
Richard

The issue is that dg-additional-files-options/gcc_adjusted_linker_flags
add the "-Wl," prefix to the content of the global variable <gluefile>
and not to the one of <option>, thus if this chunk of code is placed
beforei, <options> is already populated with "libs=$gluefile" and lacks
the prefix.  Notice that this is the case only for the first test
compiled in a tested .exp file, the next ones will have the adjusted
gluefile content.

For -T, this is another issue not covered by this patch, it is not
handled by <gcc_adjust_linker_flags_list> like "-Xlinker" thus a "-Wl,"
prefix is placed between -T and the linker file, we'll send another
patch to fix that issue.

Thanks,
Yvan

Ah, OK, I thought the patch was fixing the -T issue too.
If it's just fixing the ordering problem then it all makes sense. :-)

So yeah, the patch is OK for trunk, thanks.  Please follow the
instructions on https://gcc.gnu.org/gitwrite.html to get write access
(listing me as sponsor), but I can commit it for you if you prefer.
