IR generation now includes (often extraneous) phis, blocks are ordered reasonably, and overall shape is looking SSA-ish.
Using the Filled/Sealed approach from Braun 2013 for phi generation, and doing a bit of simple direct-to-SSA-from-AST assembly similar to that described in Brandis/Mössenböck 1994.
Need to explore some more complex test cases and finish up codegen for struct/array access, etc, and then it'll be on to adventures in register allocation.
Finding the balance for writing-a-bunch-of-new-code in a personal project is always fun.
I want to checkpoint often enough that if I can recover from mistakes without too much pain, but I definitely don't want to be committing just a constant spew of super-tiny changes that do little in isolation.
I sort of split the difference by trying to reasonably summarize the component micro-commits, as it were. Also try to ensure everything stays buildable.
