It also builds upon the concept of externally described data structures, a way of soft coding the host variables used by fixed-list dynamic SQL.
CLR JIT只能跟踪固定数目的寄存器分配变量;一旦需要跟踪的数目超出这个数目,它就开始将寄存器的内容移到内存中。
The CLR JIT can only track a fixed number of variables for register allocation; once it has to track more than this, it begins to spill the contents of registers into memory.
Well, it turns out C, like a lot of languages, comes out of the box with a whole bunch of built-in variable types.
