Subject: Do not promote float params to double in varargs
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d75686a471ee6ed5260e29d22d54f15152bbc9b4;p=oota-llvm.git

Do not promote float params to double in varargs
calls here.  This was done earlier for params in
the varargs part of the params; any float params
that survive to here are in the non-varargs part,
and must not be promoted.
