  1. Static single-assignment form

    In compiler design, static single assignment form (often abbreviated as SSA form or simply SSA) is a type of intermediate representation (IR) where each variable is assigned exactly once. SSA is used in most high-quality optimizing compilers for imperative languages, including LLVM, the GNU Compiler Collection, and many commercial compilers.. There are efficient algorithms for converting ...

  2. Static Single Assignment (with relevant examples)

    Static Single Assignment was presented in 1988 by Barry K. Rosen, Mark N, Wegman, and F. Kenneth Zadeck.. In compiler design, Static Single Assignment ( shortened SSA) is a means of structuring the IR (intermediate representation) such that every variable is allotted a value only once and every variable is defined before it's use. The prime use of SSA is it simplifies and improves the ...

  4. CS 6120: Static Single Assignment

    Wrong! Many compilers convert programs into static single assignment (SSA) form, which does exactly what it says: it ensures that, globally, every variable has exactly one static assignment location. (Of course, that statement might be executed multiple times, which is why it's not dynamic single assignment.) In Bril terms, we convert a ...

  5. SSA (GNU Compiler Collection (GCC) Internals)

    13.3 Static Single Assignment ... Multiple assignments to the same variable create new versions of that variable. Naturally, actual programs are seldom in SSA form initially because variables tend to be assigned multiple times. The compiler modifies the program representation so that every time a variable is assigned in the code, a new version ...

  6. Understanding static single assignment forms

    With thanks to Niki Carroll, winny, and kurufu for their invaluable proofreading and advice.. Preword. By popular demand, I'm doing another LLVM post.This time, it's single static assignment (or SSA) form, a common feature in the intermediate representations of optimizing compilers.. Like the last one, SSA is a topic in compiler and IR design that I mostly understand but could benefit from ...

    •CFGs but with immutable variables •Plus a slight "hack" to make graphs work out •Now widely used (e.g., LLVM) •Intra-procedural representation only •An SSA representation for whole program is possible (i.e., each global variable and memory location has static single assignment), but difficult to compute 7

  10. PDF Static Single Assignment

    Static single-assignment form arranges for every value computed by a program to have a unique assignment (aka, "definition") A procedure is in SSA form if every variable has (statically) exactly one definition SSA form simplifies several important optimizations, including various forms of redundancy elimination
