Dead code elimination

Dead code elimination deletes code that never gets executed. For example,... 

Secondly, the checks run by the verifying compilers are usually not based on abstract interpretation. They are mostly realized as abstract syntax tree transformations much in the line with the supporting routines of the compilation process (data and control flow graph analysis, dead code elimination, register allocation, etc.) and the evaluation function is basically the matching of antipatterns of common programming bugs.

Applies optimizing compiler transformations, including constant folding, common subexpression elimination, dead code elimination, loop retiming, loop pipelining, loop unrolling, and loop jamming. 

Uses various compiler transformations, including constant folding and dead code elimination. 

Similar to dead code elimination in optimizing compilers. Dead Vtbody Elimination removes a vtbody that is not called by other vtbodies. An automated version of the transformation is also available that removes all vtbodies not called by others. For example, applying Dead Vtbody Elimination to the VT on the right side of Figure 3-2 would remove vtbody V2 B, which is no longer referenced by other vtbodies. This transformation is typically applied after Vtbody Inline Expansion. 

Flow Analysis This phase uses classical flow analysis algorithms [Aho86] to analyze the lifetimes of variables, to determine live and dead variables, and to eliminate dead code. In the general synthesis path, dead code elimination is performed by the transformations, and lifetime analysis is performed by EMUCS. 

Read in your HDL code using the read command with the appropriate options. The read command performs syntax checking and basic code optimization such as, constant propagation and dead-code elimination before creating a network of logic equations and registers. 

Dead-code elimination, where operations whose effects are not visible outside the model are removed. 

Dead code elimination both immes the size of the implementation and elimi-... 

Dead-code elimination. Dead-code refers to operations that do not affect the output of the model (i.e. ports of the model). They can be eliminated without affecting the externally visible I/O behavior of the model. Dead-code elimination is recursively backtracked to remove all unnecessary operations. 

Perform automatic behavioral optimizations. In-line expansion and operator to library mapping are transformations that are guided by the designer. Upon completion of these optional user-driven transformations, a suite of automatic behavioral transformations is performed to optimize the behavior. Note that these optimizations caimot be applied to a block model because of its declarative semantics (the list of optimizations is described in Section 3.3). Optimizations include compilo -like optimizations such as dead-code elimination and variable unfolding. 

Naming conventions for variables, symbols, programs, and files Annotation/commenfing/documentation conventions Display conventions (e.g., color standards, symbologies) Provisions for adherence to modular design principles Identification of approved languages or development software Provisions for elimination of dead code ... 

Supports behavioral transformations, primarily to improve the efficiency of the control structure constant folding, common subexpression elimination, dead procedure elimination, inline expansion and formation of procedures, code motion into and out of the branches of decoding operations, and loop unrolling.
