__aeabi_memcpy and friends are not intercepted #283

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
On AAPCS ARM (including ARM/Android), memcpy intrinsic is lowered to 
__aeabi_memcpy.
The same with memmove and memset.
I also see __aeabi_memcpy8 and __aeabi_memcpy4 and the same for memmove and 
memset in Android libc.so export list, though I'm not sure if clang ever emits 
calls to them.

We do not intercept any of those, and we don't seem to have tests for them.
