200793ac21
This patch introduces preliminary support for additional memory locations. They are: target_mem0 and target_mem1 and they model memory locations that cannot be represented with existing memory locations. It was a solution suggested in : https://discourse.llvm.org/t/rfc-improving-fpmr-handling-for-fp8-intrinsics-in-llvm/86868/6 Currently, these locations are not yet target-specific. The goal is to enable the compiler to express read/write effects on these resources.
