Syntax Directed Translation Schemes

Syntax Directed Translation Schemes
SDT is a complementary notation to SDD. All applications of SDD can be implemented using SDT. SDT is a context-free grammar with program fragments called semantic actions embedded within production bodies.
Any SDT can be implemented by first building a parse tree and then performing the actions in a left-to-right depth-first order i.e. during a pre-order traversal. Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Any SDT can be implemented by first building a parse tree and then performing the actions in a left-to-right depth-first order i.e. during a pre-order traversal. Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.

Typically SDT s are implemented during parsing without building parse tree. During parsing, an action in a production body is executed as soon as all the grammar symbols to the left of action have been matched.

Postfix Translation Schemes
The simplest implementation of SDD occurs when we can parse the grammar bottom-up and SDD is S-attributed. Here, each semantic action can be placed at the end of production and executed along with the reduction of body to the head of the production.
This type of SDT is called Postfix SDT.
Example: Postfix SDT for implementing the desk calculator is as below.
