But Pentium 4 processor reoders instructions to do the same thing. So reordering by compilers is unnessecary.

I'm unsure there is public informations about that specific CPU for issue groups. Note that these are particular important in order to prevent pipeline flushings in some cases (ie: multiple L1 miss). > 2) Compilers exploit such a feature by reodering > instructions. > But Pentium 4 processor reoders instructions to do > the same thing. > So reordering by compilers is unnessecary. > > Am I right???????????? No. Instruction reordering must be helped by an ad-hoc programming of the developers. You can manually exploit this trying to access as many different registers you can in the same code-path (and in the same pipeline scope). Stupid examples: not reordering: mov (%esi), %eax mov %eax, (%edi) mov 4(%esi), %eax mov %eax, 4(%edi) mov 8(%esi), %eax mov %eax, 8(%edi) mov 12(%esi), %eax mov %eax, 12(%edi) good ordering: mov (%esi), %eax mov 4(%esi), %ebx mov 8(%esi), %ecx mov 12(%esi), %edx mov %eax, (%edi) mov %ebx, 4(%edi) mov %ecx, 8(%edi) mov %edx, 12(%edi) This is what the compiler might optimize. > 3)How many instructions does Pentium 4 processor can > look insatantly to reorder instructions? As long as NetBurst's pipeline is (20 pipeline stages). Attilio -- Peace can only be achieved by understanding - A.

And polls show that a clear majority of Americans see the war as a mistake and far fewer support the president's handling of it. Mourners honored the firefighters killed by the California arson fire as the first of five funerals began Friday, and praised authorities for charging the man accused of starting that fire with murder. Two days after the accident, the Federal Aviation Administration ordered small, fixed-wing planes not to fly over the East River unless the pilot is in contact with air traffic controllers. Violence against Iraqis has grown unabated in the past month, with more than 1,300 killed since October 1. Fearing more bloodshed after Sunday's expected announcement of a verdict in the trial of former Iraqi leader Saddam Hussein, Iraq's defense minister has canceled leave for all army officers.

Why you want this? Anyway, you can't disable interrupts for long periods of time, since interrupts are required for a lot of vital works (i.e. pagefaults). In this optic, even the "syscall handler" (exception handler of the int 0x80) is implemented through a trap gate more than an interrupt gate. And keep in mind that a lot of kernel routines working on IF, preserve the caller's eflags state (so disabling them would have no results in some cases).

The report issued Friday said the airplane was flying along the East River between Manhattan and Queens when it attempted a U-turn with only 1,300 feet of room for the turn. To make a successful turn, the aircraft would have had to bank so steeply that it might have stalled, the NTSB said in an update on the crash. The airplane, which also carried flight instructor Tyler Stanger, struck the building and fell 30 stories to the street below. Investigators do not say whether they determined who was at the controls of the Cirrus SR20.
