--- Comment #49 from Oleg Endo <olegendo at gcc dot gnu.org> 2012-08-30 22:54:23 UTC --- Kaz, if you have some time, could you please gather some CSiBE runtime numbers for '-mpretend-cmove' and without it? I've compared the result-size of the CSiBE set and with -mpretend-cmove there's a total decrease of 948 bytes, with a few opposite cases. My idea was to obsolete the -mpretend-cmove option, and instead tie its behavior the new option -mzdcbranch, which generally is supposed to control any kind of zero-displacement-branch handling.
