From: Willy Tarreau <willy@w.ods.org> Date: Sat, 31 May 2003 10:56:12 +0200 Considering that the Alpha and the UltraSparc can issue up to 4 instruction per cycle, Ultrasparc only has 2 integer units. So it really can only do 2 integer operations per cycle. GCC is giving it an optimal schedule for -mtune=ultrasparc, I know because I wrote that instruction scheduler :-) You can get 4 issue if you're doing floating point stuff. I believe the current generation Alpha has 3 integer units. GCC should be doing a good job there too. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
