[llvm-dev] LLVM Backend for a platform with no (normal) stack

[Bruce Hoult via llvm-dev]

Do you have a register that you can store a memory address in and an
addressing mode that allows you to add (or subtract) a constant to that
register and use the address calculated to load//store from memory? Do you
have enough registers that you can keep one of them permanently pointed to
a particular memory region?

If yes, then you have a stack to exactly the same extent as RISC-V or MIPS
do.
