- http://bugs.webkit.org/show_bug.cgi?id=15904 more speed-ups possible by tightening up int version of JSImmediate 1% improvement of SunSpider * kjs/JSImmediate.h: Eliminate the now-unneeded FPBitValues struct template. (KJS::JSImmediate::from): Overload for most numeric types; many types can do fewer branches and checks. (KJS::JSImmediate::getUInt32): Removed unneeded check for undefined. (KJS::JSImmediate::getTruncatedInt32): Ditto. (KJS::JSImmediate::getTruncatedUInt32): Ditto. There's no difference any more between getUInt32 and getTruncatedUInt32, so that's worth a rename and merge later. * kjs/grammar.y: Update since fromDouble is now just from. * kjs/nodes.h: Ditto. * kjs/value.h: (KJS::jsNumber): Overload for most numeric types. git-svn-id: http://svn.webkit.org/repository/webkit/trunk@27632 268f45cc-cd09-0410-ab3c-d52691b4dbfc
