* Convert the bison-output-checked-into-cvs makefile handling stuff to workChris Lattner2006-02-151-3/+16

| | | | | | | | | The ABI specifies that there is a register save area at the bottom of the stack, which means the actual used pointer needs to be an offset from the subtracted value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26202 91177308-0d34-0410-b5e6-96231b3b80d8

For example: int foo[100]; int bar[100] = {}; when compiled with C++ or -fno-common results in shrinkage from 1160 to 360 bytes of space.
