Load Vector Indexed

vec_ld(arg1, arg2)
vec_ldl(arg1, arg2)

Each operation performs a 16-byte load from a 16-byte aligned address. arg1 is an integer value, while arg2 is a pointer. arg1 is added to arg2 and the sum is truncated, if necessary, to produce 16-byte aligned result. The arg2 type may also be a pointer to a const-qualified type.
vec_ldl marks the data as Least Recently Used (LRU), while vec_ld does not; otherwise the instructions are identical.

See AltiVec Alignment for a discussion of how to load data that may not be 16-byte aligned.
