MPX ABI extension

2013-08-26 Thread Ilya Enkovich
Hi, Here is a patch to extend x86-64 psABI to support MPX [1]. A short description of changes: - There are 4 bound registers (bnd0-bnd3) added; all of them are caller-save - When we pass (return) pointer on register, we use the next available bound register to pass (return) bounds - If there i
