Subject: An array of chars of length 8 will also cause the stack protector to be inserted
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=9c674bb012c23622bd31d5e82cb0baeda9aac3a5;p=oota-llvm.git

An array of chars of length 8 will also cause the stack protector to be inserted
into the function. Reflect that here so that the array will be placed next to
the SP.
