Subject: If a module has a main, but it is defined externally, refuse to run it.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=48ba8221af97cc76cb2018ceac490d7b5d0fa6ff;p=oota-llvm.git

If a module has a main, but it is defined externally, refuse to run it.

Attempting to run it will find lli's main, which isn't the desired effect.
