From 1ecc3a2df168034b8ab33ff5ba6434ce3593dbb5 Mon Sep 17 00:00:00 2001 From: Liviu Ionescu Date: Thu, 11 Dec 2014 12:07:48 +0000 Subject: Pass semihosting exit code back to system. In order to run unit tests under semihosting, it is necessary to pass the application exit code back to the system. ARM defines only the code to be used for non-error application exit (ADP_Stopped_ApplicationExit), all other codes should return non-zero exit codes. This patch checks if the application code passed via TARGET_SYS_EXIT is ADP_Stopped_ApplicationExit, and return 0, otherwise return 1.
