- E2e.test: removed the  `--viper-config` flag. If you were previously using this to pass flags to `e2e.test` via a file, you will need to pass them directly on the command line, e.g. `e2e.test --e2e-output-dir`.

Some of the details map precisely to the machine, but some do not.
This is because the compiler suite (see
<a href="https://9p.io/sys/doc/compiler.html">this description</a>)
needs no assembler pass in the usual pipeline.
Instead, the compiler operates on a kind of semi-abstract instruction set,
and instruction selection occurs partly after code generation.
The assembler works on the semi-abstract form, so
