old-cross-binutils/gdb/testsuite/gdb.base/a1-selftest.exp
Fred Fish 89e6c70d53 * lib/gdb.exp (default_gdb_start): Fix typo.
* gdb.base/corefile.exp: Allow "Core was generated by ..."
	messages to not include the full program name that caused
	the core dump since some systems (such as solaris) apparently
	truncate this path to about 80 characters.
	When generating a core file first try increasing the core file
	size limit to unlimited since some systems may default it to
	zero, and it is harmless to try it.  Move the test for failing
	to generate a core file to where it will actually get executed.
	* gdb.c++/templates.exp (test_ptype_of_templates): Accept
	new gdb result from g++ debug info improvements and make old
	pattern obsolescent.  Also account for size_t differences
	(may be int or long).
	* gdb.base/a1-selftest.exp (test_with_self): Check for case where
	initialization before function call is placed in the delay slot
	and thus appears to be skipped over by commands such as "next".
