X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=48691f6650bbae30d702faa2fddb666763ee4995;p=thirdparty%2Fbinutils-gdb.git

gprof: Add a simple test for gprof -l

Verify that "gprof -l" works properly.

	* testsuite/Makefile.am (check_SCRIPTS): Add tst-gmon-gprof-l.sh.
	* testsuite/Makefile.in: Regenerated.
	* testsuite/tst-gmon-gprof-l.sh: New.
