ANSI-C Frontend

The Compiler Frontend reads the source files, does all the syntactic and semantic checking, and produces intermediate representation of the program which then is passed on to the backend to generate code. This section discusses features, restrictions, and further properties of the ANSI-C Compiler frontend.

This chapter covers the following topics:

• Implementation Features
  
  
• ANSI-C Standard
  
  
• Floating-Point Formats
  
  
• Volatile Objects and Absolute Variables
  
  
• Bitfields
  
  
• Segmentation
  
  
• Optimizations
  
  
• Using Qualifiers for Pointers
  
  
• Defining C Macros Containing HLI Assembler Code
