[LLVMdev] Loop localize global variables
...upstream. The basic idea is to localize global variables inside loops so
that it can be allocated into registers. For example, transform the
following sequence
static int gbl_var;
void foo() {
for () {
...access gbl_var...
}
}
into something like
static int gbl_var;
void foo() {
int lcl_var;
lcl_var = gbl_var;
for () {
...access clc_var...
}
gbl_var = lcl_var;
}
This transformation helps a couple of EEMBC benchmarks on both Aarch64 and
Hexagon backends. I was wondering if there is interest to get this
optimization upstreamed or if there is a better way of doing this....

ready, so I'm just sharing what I've found out, maybe it's helpful.
I'd be interested to hear your thoughts / approach in greater detail.
Thanks!
