Target Language Compiler
Target Language Compiler (TLC) is an integral part of the code generator. Use TLC to customize generated code. Through customization, you can produce platform-specific code and incorporate your own algorithmic changes for performance, code size, or compatibility with existing methods.
With the Target Language Compiler, you can :
Customize the set of options specified by your system target file.
Inline the code for S-Function blocks.
Generate additional or different types of files.
To learn about the basics of TLC, see Target Language Compiler Basics.
Use the Target Language Compiler to produce platform-specific code and incorporate your own algorithmic changes for performance, code size, or compatibility with existing methods that you prefer to maintain.
Use the Target Language Compiler to customize the set of options specified by your system target file, inline the code for S-Function blocks, or generate additional or different types of files.
Determine when, how, and why to inline S-functions.
Learn what information a block object captures.
Learn how the Target Language Compiler interprets
Apply techniques for inlining S-functions.
