If old dump files for a testcase are left, if the name of the dump file has changed, errors like the following occur:
ERROR: gcc.dg/tree-ssa/structopt-1.c: error executing dg-final: couldn't open "structopt-1.c.t50.lim structopt-1.c.t53.lim": no such file or directory UNRESOLVED: gcc.dg/tree-ssa/structopt-1.c: error executing dg-final: couldn't open "structopt-1.c.t50.lim structopt-1.c.t53.lim": no such file or directory Deleting all generated *.c.t* files in the testsuite directory, solves this problem.
