------- Additional Comments From e9925248 at stud4 dot tuwien dot ac dot at 2005-06-05 13:01 ------- The example was taken out of a test log created at the beginning of May. The current log where simliar failures for a lot files occured was not available any more, because I had overwritten it with a new run, after deleting the files causing the errors to verify the solution.
To problem is, that the testsuite searches for pattern XXXX.t??.XXX, if it wants to open a dump file, and try to open the result. If multiple files match this pattern, such an error occurs (see lib/scantree.exp). To reproduce it on a clean directory, create a file named ssa-sink-1.c.t46.sink (such a file was created some time ago by a testsuite run, because some error occured while checking this testcase) in the testsuite run directory (where gcc.sum is put). A make check prints then the following error: ERROR: gcc.dg/tree-ssa/ssa-sink-1.c: error executing dg-final: couldn't open "ssa-sink-1.c.t46.sink ssa-sink-1.c.t52.sink": no such file or directory It leaves additionally ssa-sink-1.c.t52.sink in the directory. If the number of the sink pass would change again, a third file would appear in the error message. I know, this is not a severe error, as a rm -f testsuite/*.c.t* before each make check solves the problem. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21910
