Library-function test-driver

[Artoria2e5]

The current test driver is based on string (usually stdout and argv) I/O and is not quite convenient to call from more restrictive environments such as iOS. A graphics environment might also want to display the results without too much string manipulation. A more "struct-ured" (pardon my pun) API taking a struct input (multithread, seed) and a struct output (anything printed) might be more adequate and portable. core_results is 90% there already.

The less intrusive way is to redirect main and ee_printf. Basically the caller calls the renamed core_main supplying argc and argv, then retrieve the result from a global buffer that the new printf writes to.

This can be achieved without modifying the 5 core files -- ifdef is enough to rename main(). The makefile still needs to be taken down and rewritten.

Hi there,

Regarding the printf redirection, currently coremark.h has the following codes:

#include "core_portme.h"

#if HAS_STDIO
#include <stdio.h>
#endif
#if HAS_PRINTF
#define ee_printf printf
#endif

If HAS_STDIO and HAS_PRINTF are not defined, you can define your own implementation of ee_printf
in core_portme.h. For example, you can use sprintf to print the messages in a text buffer,
then output the messages using system specific interface.

Would that solve the printf problem?
I need to think about the main() issue a bit more. Get back to you on this later.

Joseph
