Subject: Make sure that the call stack adjustments have default operands. Also
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=fb0b892f7ebee68760645dd220f88bd9177cf2e4;p=oota-llvm.git

Make sure that the call stack adjustments have default operands. Also
leave custom lowerings for later.

Fixes some nightly tests.
