simple libc tests based on the libc-testsuit

and libc-bench of dalias

see http://git.etalabs.net/cgi-bin/gitweb.cgi

see http://www.etalabs.net/libc-bench.html

build tests:

	cp Makefile.conf.def Makefile.conf

	# edit Makefile.conf

	make

run tests:

	./t

run benchmarks:

	./b

framework:

the only hook in the test framework is error(...) which

prints a formatted message and sets the test to failed

see common/test.h

in the root directory make builds an executable with all tests

in a src/* directory make builds only local tests

see Makefile.inc

a test function looks like

	void test_foo() {

		if (foo != 42)

			error("foo=%d expected 42\n", foo);

	}

extern functions with name ~ /^test/ are recognized to be

test functions

see Makefile.inc

a benchmark function looks like

	void bench_foo(int N) {

		for (i = 0; i < N; i++)

			foo();

	}

benchmark functions are repeatedly called with an increasing

N until the runing time is long enough, then time/N is printed

edit the generated tests.h to exclude certain tests

see common/t.c for tests

see common/b.c for benchmarks
