Fix mingw32 failures due to incorrect directory separator in pattern Some testcases, mostly gdb.reverse ones, assume the presence of a '/' directory separator before the source file name. This is incorrect for mingw32 hosts, generating false failures for those tests. I attempted to catch most of the occurrences of the pattern ".*/$srcfile" and replaced them with ".*$srcfile". The latter is used elsewhere in the testsuite. The resulting patch is attached. I also see other occurrences of the same assumption throughout the testsuite, but usually they are arguments for function calls and i seem to recall either the test harness or GDB deals with those paths properly. gdb/testsuite: 2014-10-17 Luis Machado <lgustavo@codesourcery.com> * gdb.guile/scm-breakpoint.exp: Do not assume any directory separators when matching source file paths. * gdb.python/py-breakpoint.exp: Likewise. * gdb.reverse/break-precsave.exp: Likewise. * gdb.reverse/break-reverse.exp: Likewise. * gdb.reverse/consecutive-precsave.exp: Likewise. * gdb.reverse/finish-precsave.exp: Likewise. * gdb.reverse/finish-reverse-bkpt.exp: Likewise. * gdb.reverse/finish-reverse.exp: Likewise. * gdb.reverse/i386-precsave.exp: Likewise. * gdb.reverse/i387-env-reverse.exp: Likewise. * gdb.reverse/i387-stack-reverse.exp: Likewise. * gdb.reverse/machinestate-precsave.exp: Likewise. * gdb.reverse/machinestate.exp: Likewise. * gdb.reverse/sigall-precsave.exp: Likewise. * gdb.reverse/solib-precsave.exp: Likewise. * gdb.reverse/step-precsave.exp: Likewise. * gdb.reverse/until-precsave.exp: Likewise. * gdb.reverse/watch-precsave.exp: Likewise. * gdb.reverse/watch-reverse.exp: Likewise.
