‘clobber’ ensures that the register is free before entering and after exiting an instruction. Therefore you can’t use it to say a register is used then destoryed by an instruction such as LOADACC, (X+) on X.

Took a while to figure this out

GCC is crazy.  It recognises a printf(’foo\n’) and turns it into the equivalent puts(’foo’) instead.

builtins.c has all types of similar transformations including printf(’%c’, v) to a putch(v) and printf(’%s’, v) to fputs().

The Cii seems interesting. It needs more publicity - this is the first time I’ve heard of it in my fifteen years in Christchurch.
