From 15e19273b2a6ebda3b2d55b28d693e7b8a0740b2 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Tue, 21 Nov 2017 11:29:01 +0100 Subject: sapi: New implementation of rtems_panic() The previous rtems_panic() implementation was quite heavy weight. It depended on _exit() which calls the global destructors. It used fprintf(stderr, ...) for output which depends on an initialized console device and the complex fprintf(). Introduce a new fatal source RTEMS_FATAL_SOURCE_PANIC for rtems_panic() and output via vprintk(). Update #3244. --- cpukit/sapi/include/rtems/fatal.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'cpukit/sapi/include/rtems') diff --git a/cpukit/sapi/include/rtems/fatal.h b/cpukit/sapi/include/rtems/fatal.h index 80929cd274..291af42c6e 100644 --- a/cpukit/sapi/include/rtems/fatal.h +++ b/cpukit/sapi/include/rtems/fatal.h @@ -88,6 +88,18 @@ RTEMS_NO_RETURN RTEMS_INLINE_ROUTINE void rtems_fatal( _Terminate( fatal_source, error_code ); } +/** + * @brief Prints the specified message via printk() and terminates the system. + * + * @param[in] fmt The message format. + * @param[in] ...
