380 C-COMPILER USER’S MANUAL

CHAPTER 1

INTRODUCTION

The 380 C-Compiler conforms to the ANSI’s definition of a “freestanding implementation”,

with the exception that doubles are 32 bits. In accordance with the definition of a freestand

ing implementation, the compiler accepts programs which confine the use of the features of

the ANSI standard library to the contents of the standard headers <float.h>, <limits.h>,

<stdarg.h> and <stddef.h>. This release supports more of the standard library than is required

of a freestanding implementation, as described in

Chapter 4, Run Time Environment.

There are several language extensions supported in this version, including interrupt functions

and memory space accesses.
