It compiled to "M-Code" and linked in the runtime engine.  Programs may have run somewhat slower than the output from a true native compiler but the intermediate code was very compact and, I believe, relocatable.  My application had a lot of hardware interface requirements and TM2 supported modules written in Z80 assembler for bit-tickling.  There was even a special version written to take advantage of Zilog Z180 / Hitachi 64180 memory mapping.  That variant
