Not sure you were following the
 "testsuite/gdb.dwarf2: Fix for dw2-ifort-parameter failure on ARM"
thread.  Seems to me this exact same thing should be done to
dw2-ifort-parameter.c.  I assume that test is currently failing
on ppc64 for the exact same reason, and that if it's not failing
on S390 with current gcc, it'll be by lucky alignment.  I believe
this approach should fix Thumb there as well.  Can you guys
coordinate on handling that test?  Thanks.
