Subject: Check that there is a param context list before trying
X-Git-Tag: m5_2.0_beta3~185
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=01f32efa4b3c25ad6323ec3e76d756b442a8f419;p=gem5.git

Check that there is a param context list before trying
to loop through it.  This is more important as we get rid
of param contexts
