Subject: pseudo_inst: clean up workbegin/workend functions
X-Git-Tag: stable_2012_02_02~55
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ba79155d9d0f42457f74b533e27f0af2ab1b5e4a;p=gem5.git

pseudo_inst: clean up workbegin/workend functions
Use exitSimLoop() function instead of explicitly scheduling
on mainEventQueue (which won't work once we go to multiple
event queues).  Also introduced a local params variable to
shorten a lot of expressions.
