In our architecture there is 2 disjoint address spaces for data memory and
we need 2 stacks in each address space.
As I understand, there is no support for this in clang and llvm backend.
Clang doesn't allow to specify 'address_space' attribute for locals.
LLVM codegen doesn't lower alloca if address space of alloca differs with
that is specified in datalayout.
So, is there any thoughts how to implement 2 independent stacks?
Is it possible to distinguish frame indexes of 2 different stacks?
Is there any support of several stacks in stack coloring and stack frame?
