This handles the simplest case for mov -> push conversion: 1. x86-32 calling convention, everything is passed through the stack. 2. There is no reserved call frame. 3. Only registers or immediates are pushed, no attempt to combine a mem-reg-mem sequence into a single PUSHmm. Differential Revision: http://reviews.llvm.org/D6503 llvm-svn: 223757
