If an alloca only has two types of uses: 1) reads 2) a memcpy/memmove that
...
copies from a constant global, then we can change the reads to read from the
global instead of from the alloca. This eliminates the alloca and the memcpy,
and promotes secondary optimizations (because the loads are now loads from
a constant global).
This is important for a common C idiom:
void foo() {
int A[] = {1,2,3,4,5,6,7,8,9...};
... only reads of A ...
}
For some reason, people forget to mark the array static or const.
