ValidationError: Graph must be in single static ... WebStatic Single Assignment Form Many of the complexities of optimization and code generation arise from the fact that a given variable may be assigned to in many different places. Thus reaching definition analysis gives us the set of assignments that may reach a given use of a variable. Live range analysis must track all assignments that may ...

Converting ordinary code into SSA form is primarily a matter of replacing the target of each assignment with a new variable, and replacing each use of a variable with the "version" of the variable reaching that point. For example, consider the following control-flow graph: Changing the name on the left hand side of "x x - 3" and changing the following uses of x to that new name would leave the program unaltered. This can be exploited in SSA by creating two ne… WebAfter coalescing, the whole graph must then be rebuilt because eliminating the copies might have changed the interference relationships. A conservative approximation can be used incrementally, to allow multiple copies to be coalesced in a single pass, however a proper rebuild of the graph must be done afterwards for complete accuracy. sharing collections in edge

WebWhen constructing a medium level IR, the IR generator must be told about the sizes of source language datatypes. Assume for the following example that doubles require 8 bytes and ints require 4 bytes: ... SSA: single … Webultimately resulting in an approximately 30% speedup for the largest graphs. We believe this is because, in general, larger graphs have more complicated control flow. The amount of work done by the Cytronet al. algorithm grows as a function of the size of the dominance-frontier sets, whereas our formulation grows with the size of the cfg ...
