From: Doug Evans Date: Thu, 11 Oct 2012 15:59:57 +0000 (+0000) Subject: * lib/gdb.exp (gdb_breakpoint): Fix varargs scan. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5b7d00507b;p=binutils-gdb.git * lib/gdb.exp (gdb_breakpoint): Fix varargs scan. Recognize "message" -> print pass and fail. Add eof case. (runto): Recognize message, no-message. Print pass/fail if requested, with same treatment as gdb_breakpoint. (runto_main): Pass no-message to runto. (gdb_internal_error_resync): Add log message. (gdb_file_cmd): Tweak internal error fail text for consistency. --- diff --git a/gdb/testsuite/ChangeLog b/gdb/testsuite/ChangeLog index 4eb19bdf62d..b58e3517255 100644 --- a/gdb/testsuite/ChangeLog +++ b/gdb/testsuite/ChangeLog @@ -1,3 +1,13 @@ +2012-10-11 Doug Evans + + * lib/gdb.exp (gdb_breakpoint): Fix varargs scan. + Recognize "message" -> print pass and fail.
