llvm emits unoptimized code
Hi Devs,
Consider testcase here
https://godbolt.org/z/qHZzqw
When optimization is O1 or above it produces unoptimized code
because it calls __tls_get_address in loops.
While with optimization disabled
It produce single call to __tls_get_address outside of loop.
is this a missed optimization by llvm?
