Add new keywords to config. The options availible in file.i386 are now:
/* * filename [ standard | optional ] [ config-dependent ] * [ dev* | profiling-routine ] [ device-driver] [ no-obj ] * [ compile-with "compile rule" [no-implicit-rule] ] * [ dependancy "dependancy-list"] */ I added no-obj - This entry does not create anything linkable to the kernel. dependancy - Add additional dependancy rules to a target. no-implicit-rule - Don't assume .c -> .o type rules. Config is really dumb in this area and assumes that everything is a .c file irregarless of extention. This was the best choice really since there may even be .c file that you don't want to follow the standard rules. This was all done so that the building to the aic7770 assembler and using the aic7770 assembler in the building of the aic7770 driver could be config dependant. I can now have an entry like this for the driver: aic7770 optional ahc device-driver \ compile-with "${CC} $> -o $@" \ dependancy "$S/gnu/misc/aic7770/aic7770.c" \ no-obj no-implicit-rule aic7770_seq.h optional ahc device-driver \ compile-with "${.CURDIR}/aic7770 -o $@ $S/gnu/misc/aic7770/aic7770.seq"\ dependancy "$S/gnu/misc/aic7770/aic7770.seq aic7770" \ no-obj no-implicit-rule i386/isa/aic7770.c optional ahc device-driver \ dependancy "aic7770_seq.h" I also added '\' escaping to newlines so that this doesn't look as gross as it could have.
