When emitting the function epilog, check to see if there already a stack
adjustment. If so, we merge the adjustment into the existing one. This allows us to generate: caller2: sub %ESP, 12 mov DWORD PTR [%ESP], 0 mov %EAX, 1234567890 mov %EDX, 0 call func2 add %ESP, 8 ret 4 intead of: caller2: sub %ESP, 12 mov DWORD PTR [%ESP], 0 mov %EAX, 1234567890 mov %EDX, 0 call func2 sub %ESP, 4 add %ESP, 12 ret 4 for X86/fast-cc-merge-stack-adj.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22038 91177308-0d34-0410-b5e6-96231b3b80d8
