instead of sti to it restore to its usual state. pushfl/popfl is actually faster in protected mode on Pentiums (4+3 cycles instead of 9), and using sti made it extremely inconvenient to call microtime() from fast interrupt handlers. pushfl/popfl is a couple of cycles slower than sti on 486's and a couple more cycles slower on 386's, but the relative cost of using it is not large since microtime() has to use slow i/o instructions on the old cpus. |
