History

justinbeech 62b104cbfa Found free extra 256 bytes of RAM eliminate _clz use from libgcc ... Believe it or not, changing / 2^31 to >>31 saved 256 bytes in the "d" segment. The reason is that GCC version prior to 4.3.5 does not have a count_leading_zeros (clz) assembler macro, so it uses a 256 byte lookup table called _clz The _clz table gets pulled in if you do 64 bit division. This tiny change is the only place that we do long long division. Changing to a shift saves 256 bytes of ram.		13 years ago
