This module allows m5ops to be executed in Lua programs.
To compile it (in util/m5):
The following command generates Lua moduel, gem5OpLua.so.
make -f Makefile.<arch> gem5OpLua.so
To use it:
First, put gem5OpLua.so in Lua library search path.
Then, import the module and execute the m5op function.
Example usage, creating a checkpoint.
m5 = require("gem5OpLua")
m5.do_checkpoint(0, 0)
