This was the warning (shown for __aeabi_memcpy, __aeabi_memcpy4 and
__aeabi_memcpy8):
ArmPkg/Library/CompilerIntrinsicsLib/memcpy.c:42:6:
error: '__aeabi_memcpy8' alias between functions of incompatible types
'void(void*, const void *, size_t)'
{aka 'void(void *, const void *, unsigned int)'}
and 'void *(void *, const void *, size_t)'
{aka 'void *(void *, const void *, unsigned int)'} [-Werror=attribute-alias]
void __aeabi_memcpy8(void *dest, const void *src, size_t n);
ArmPkg/Library/CompilerIntrinsicsLib/memcpy.c:19:7: note: aliased declaration here
void *__memcpy(void *dest, const void *src, size_t n)
The problem is the different return type (void vs void*). So reshuffle
the code so the prototypes match between the aliases.
