Subject: swig: get rid of m5.internal.random module (swig/random.i)
X-Git-Tag: stable_2012_02_02~471
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cc14689a86d4a17bc8d8c77a24539d45e7f78da9;p=gem5.git

swig: get rid of m5.internal.random module (swig/random.i)
Thanks to swig this was interfering with the standard Python
random module.  The only function in that module was seed(),
which erroneously called srand48().  Moved the function to
m5.internal.core, renamed it seedRandom(), and made it call
random_mt.init() instead.
