1.1 anton 22: \ This is not very nice (hard limits, no checking, assumes 1 chars = 1)
23:
24: \ Optimizations:
25: \ superfluous stores are removed. GCC removes the superfluous loads by itself
26: \ TOS and FTOS can be kept in register( variable)s.
27: \
28: \ Problems:
29: \ The TOS optimization is somewhat hairy. The problems by example:
30: \ 1) dup ( w -- w w ): w=TOS; sp-=1; sp[1]=w; TOS=w;
31: \ The store is not superfluous although the earlier opt. would think so
32: \ Alternatively: sp[0]=TOS; w=TOS; sp-=1; TOS=w;
33: \ 2) ( -- .. ): sp[0] = TOS; ... /* This additional store is necessary */
34: \ 3) ( .. -- ): ... TOS = sp[0]; /* as well as this load */
35: \ 4) ( -- ): /* but here they are unnecessary */
36: \ 5) Words that call NEXT themselves have to be done very carefully.
37: \
38: \ To do:
1.8 pazsan 39: \ add the store optimization for doubles
1.1 anton 40: \ regarding problem 1 above: It would be better (for over) to implement
41: \ the alternative
