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.
