--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> ---
The commit r14-1949-g957ae90406591739b68e95ad49a0232faeb74217 did change
in  gcc/gensupport.cc the following.

@@ -553,10 +1048,12 @@ process_rtx (rtx desc, file_location loc)
   switch (GET_CODE (desc))
     {
     case DEFINE_INSN:
+      convert_syntax (desc, loc);
       queue_pattern (desc, &define_insn_tail, loc);
       break;

     case DEFINE_COND_EXEC:
+      convert_syntax (desc, loc);
       queue_pattern (desc, &define_cond_exec_tail, loc);
       break;


IMHO it seems as if there shouldn't be a convert_syntax for
DEFINE_COND_EXEC - or 's' needs to be accepted for it
or rtl.def needs to be change to have a 'T' and not an 's'.=
