The listings I've read of early unix have ...
mixed c + assembly
Not V6 (the subject of the current discussion); the C compiler of that era
couldn't inline assembler.
_ALL_ of the assembler in V6 is in one of _two_ files:
l.s - per system, hardware configuration dependent
m40.s - Startup, and machine language support for all low-level OS
or functions such as stack switching, etc; the latter option
m45.s supported both the -11/45 and -11/70
