Here is a paper about PL.8 research compiler used in IBM RISC research in mid-70's. http://rsim.cs.illinois.edu/arch/qual_papers/compilers/ausla... Key points, using a memory safe systems programming language which apparently would be too slow for the target hardware, thanks to the compiler IL representation and multiple execution phases (sounds similar?) achieves the goal of being usable to write OS in 70's hardware. |
