PROGRAMMING TOOLS

Benchmarks prove that Lattice C produces consistently faster, smaller executable programs. With new features and options, the Lattice C Compiler lets you take advantage of the very latest compiler technology.

Code-Enhancing Global Optimizer speeds your programs up to 30%! The Lattice global optimizer analyzes your program to perform one or more of its many code-enhancing operations whenever beneficial. Optimizing techniques employed including:

• Convert functions to in-line code
• Assign variables to registers for all or part of their lifetime according to usage.
• Eliminate stores of values which are never fetched
• Eliminate code with values that are not used
• Eliminate recalculation of values that have been previously computed
• Move calculations outside a loop when they are the same on each iteration
• Eliminate unused auto variables

• strlen
• memcpy
• emchr
• memset
• inp
• outp
• STI
• CLI

• private-defines data that must be replicated for each execution thread
• critical-defines a function that must run as a critical section
• inline-lets you create your own built-in functions
• interrupt-simplifies the development of DOS interrupt handlers and TSR programs

• change the default padding and alignment options
• allow the compiler to continue with the next source file when a fatal error is reported
• allow deviations from the ANSI C language standard
• activate the debugging mode when no variable field is given
• define preprocessor symbols as if they had been included in the source file
• generate in-line 8087 or 80287 floating point operations
• produce files with function prototypes
• set whether the compiler will generate DOS, Family Mode, OS/2, OS/2 PM, or Rommable code
• automatically invoke the Lattice linker
• cause the compiler to compile only source files which are newer than the corresponding object files
• automatically insert object modules into a library file
• change the default segment names generated by the compiler
• undefine all preprocessor symbols that are normally predefined by the compiler

Many library functions have been rewritten and all library functions have been recompiled using Lattice's new global optimizer to give you the fastest possible program execution. In addition, Lattice provides:

Special Libraries that make it easier than ever to add new capabilities to your applications.

• GFX Graphics Library lets you take advantage of Hercules, CGA, MDA, EGA, and VGA graphics cards for creating and manipulating graphic images as well as opening movable windows for graphic work.
• dBC III Database Library lets you create, access, and update files that are compatible with dBASE III. dBC III includes all the functions you need to create complete ISAM database programs.
• Lattice Communications Library lets you add asynchronous communications to your applications. The library includes functions that provide complete control of the computer's serial ports as well as high-level functions for popular file transfer protocols.
• Curses Screen Management Library Curses lets you write text to a Unix System V compatible virtual screen, move the cursor, scroll the screen,m overlay screens, outline, insert, delete, clear, highlight, and much more.
