--- Comment #12 from Richard Biener <rguenth at gcc dot gnu.org> --- Well, it was also about "GCC sucks, I need to add 20 options to get to the level of optimization, using ICC I can just use -fast". So it's about convenience, and building on the apparent connotation of "fast" with "slightly unsafe in some cases" people apparently knew.
