get length of ascii string, scanning 4 bytes at a time, plus auto aligning unaligned pointers to 4 byte boundary.
update1: size optimizations. update2: replace cmp with test.

I thought asm was to make smaller executables.

Asm lets me build and run x86 code on ARM tablet which is not allowed to build native apps for itself.
I can take a virtual 386 with me anywhere. Almost weightless. Could we dream of it in 90s? Upd: why not real Windows tablet. High price, buggy, Windows updates breaking everything, bad power saving. And Windows UI just doesn't fit for PDA. |
