Hand-Hacking

/hand-hakiƋ/

n. 1. The practice of translating hot spots from an HLL into hand-tuned assembler, as opposed to trying to coerce the compiler into generating better code. Both the term and the practice are becoming uncommon.

See tune, bum, by hand; syn. with v. cruft.

2. More generally, manual construction or patching of data sets that would normally be generated by a translation utility and interpreted by another program, and aren't really designed to be read or modified by humans.
