<pre>X86RegisterInfo::X86RegisterInfo has
// Use a callee-saved register as the base pointer. These registers must
// not conflict with any ABI requirements. For example, in 32-bit mode PIC
// requires GOT in the EBX register before function calls via PLT GOT
pointer.
BasePtr = Is64Bit ? X86::RBX : X86::ESI;
For Target64BitILP32, it should be X86::EBX.</pre>
