I love QBE, but it does have its limitations:
- It handles the ABIs for passing and returning structures in registers, but only with superfluous copies to and from the stack.
- Can't generate debug info for data. This is probably due to lack of assembler support and/or complexity in the DWARF format.
- The line number debug info directives are currently undocumented and don't support inlined functions.
But it's smol, effective, and it doesn't make you deal with phi nodes!
