2008-09-27gcc: Add extra parens to quell warnings.Nathan Binkert
Even though we're not incorrect about operator precedence, let's add some parens in some particularly confusing places to placate GCC 4.3 so that we don't have to turn the warning off. Agreed that this is a bit of a pain for those users who get the order of operations correct, but it is likely to prevent bugs in certain cases.
2008-09-26O3CPU: Fix thread writeback logic.Kevin Lim
Fix the logic in the LSQ that determines if there are any stores to write back. In the commit stage, check for thread specific writebacks instead of just any writeback.
2008-09-26O3CPU: Add a hack to ensure that nextPC is set correctly after syscalls.Kevin Lim
Just check CPU's nextPC before and after syscall and if it changes, update this instruction's nextPC because the syscall must have changed the nextPC.
2008-09-22gcc: Version 4.3 is pretty anal about shadowing types, placate it.Nathan Binkert
In the future, it would be nice to put the O3CPU into its own namespace so that we don't end up hardcoding pointers to the global namespace.
2008-09-10style: Remove non-leading tabs everywhere they shouldn't be. Developers ↵Ali Saidi
should configure their editors to not insert tabs
2008-08-18Changed BaseCPU::ProfileEvent's interval member to be of type Tick. This was ↵Richard Strong
done to be consistent with its python type of a latency. In addition, the multiple definitions of profile in the different cpu models caused problems for intialization of the interval value. If a child class's profile value was defined, the parent BaseCPU::ProfileEvent interval field would be initialized with a garbage value. The fix was to remove the multiple redifitions of profile in the child CPU classes.
2008-08-11params: Convert the CPU objects to use the auto generated param structs.Nathan Binkert
A whole bunch of stuff has been converted to use the new params stuff, but the CPU wasn't one of them. While we're at it, make some things a bit more stylish. Most of the work was done by Gabe, I just cleaned stuff up a bit more at the end.
2008-07-01Remove delVirtPort() and make getVirtPort() only return cached version.Ali Saidi

a newly created one can.

--HG-- extra : convert_revision : d811bf87d1a0bfc712942ecd3db1b48fc75257af
2008-01-14The reason is that the event is supposed to put the instructions ready to ↵Ke Meng
execute for next cycle. And the FUCompletion event has a lower priority than CPU tick event. It is called after the iew->tick() for current cycle has already been executed and the issueToExecuteQueue has already advanced this time. And assume the issueToExecuteLatency is 1, to catch up, the increasement should be made at access(-1) instead of access(0). Otherwise I found it could increase the actual op_latency of the instructions to execute by 1 cycle and potentially put the simulated CPU into a permanent idle state.
