MadeEasy Test Series: Compiler Design - Static Single Assignment
Consider the following code segment: $c=b+a$ $e=c-a$ $f=c*e$ $h=c+a$ $i=h+f$ The minimum number of temporary variable required to convert the above code segment to static single assignment form is ________. Doubt : Are we ... do minimizations in SSA? if YES then is it always the case, if NO when do we have to do it. Please clarify.

MadeEasy Test Series: Compiler Design - Static Single Assignment
What is the Static Single Assignment (SSA) form for the following code segment: a = b+c; c = a+x; d = b+c; d = a+x; Should we use only 1 temporary variable for c=a+x and d=a+x because both of them evaluate the same expression finally?

Static Single Assignment
Definition of Static Single Assignment Static single-assignment form arranges for every value computed by a program to have a unique assignment (aka, “definition”) but p3 = a - b q4 = p3 * c p4 = u * v q5 = p4 + q4 is an valid example of SSA Now, tell me a,b,c,u,v are not assigned or previously recognized Then how this is a valid example of SSA? for ref see here
