| /* 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. */ |
