+/* This file tests most of the non-C++ run-time helper functions
+   described in Section 4 of the "Run-Time ABI for the ARM
+   Architecture".  These are basic tests; they do not try to validate
+   all of the corner cases in these routines.  
+
+   The functions not tested here are:
+
+     __aeabi_cdcmpeq
+     __aeabi_cdcmple
+     __aeabi_cdrcmple
+     __aeabi_cfcmpeq
+     __aeabi_cfcmple
+     __aeabi_cfrcmple
+     __aeabi_ldivmod
+     __aeabi_uldivmod
+     __aeabi_idivmod
+     __aeabi_uidivmod
+
+   These functions have non-standard calling conventions that would
+   require the use of inline assembly to test.  It would be good to
+   add such tests, but they have not yet been implemented.  
+
+   There are also no tests for the "division by zero", "unaligned
+   memory access", "memory copying, clearing, and setting"
+   functions.  */
