+- `gc.h` is the per-target header (Plan 9 cc convention). `cgen.c` performs the current AST lowering into a `Prog` list, including switch lowering; `txt.c` emits the assembler text. There is no peephole or register-allocation pass yet.
 - The text output must be readable by `w6a` (the amd64 assembler under `../w6a/`). When in doubt about syntax, run `w6a` on the output.
