Acronym of SSA

( Static Single Assignment ) In the design of the compiler, form the allocation of single or the same SSA, a feature show is an intermediate, which requires every variable before use, define, and only a time will be allocated. The available variables in the IR, the main categories are divided; the new variables, usually with the original name with a subtitle in the books mentioned are, etc., so that each definition, in a particular category can fit. In the method, SSA, etc. chains, the use of the definition is obvious and each of them has a Element set up there. Each variable in the text of the program exactly one value of obtaining it. (But this does not mean that we can't in the loop program we have)
