(OP) (LIT) (BRANCH) (BRANCH>) (RESOLVE) (LABEL), entries 6-11: the code generator of any language built on the machine (MACHINE.md 2.1). asm.c's layout rules with text.c's branch placement; 400 random sequences agree word for word with asm.c at both widths, memory-full and out-of-reach are refused on both sides, and a ref with no branch is refused, not looped on.

|
|
* Runs on the build machine, built for the host node (HOST_WORDS and the
|
|
* host stack sizes) at one cell width. It writes, as `constant` lines in
|
|
* the text assembler's notation, the addresses and codes of
|
|
* v4/tests/host_map.h that the ROM's source (capsules/v4/rom) uses: the
|
|
* console's receive registers and the ROM's state area (MACHINE.md 2.1).
|
|
* The map has one source, host_map.h; this is how the ROM reads it.
