INTRODUCTION
The 380 C-Compiler is an optimized ANSI C- C-Compiler. The 380 C-Compiler
meets ANSI's definition of a "freestanding implementation", with the exception
that doubles are 32 bits. In accordance with the definition of a freestanding imple-
mentation, 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>, <lim-
its.h>, <stdarg.h> and <stddef.h>. This release supports more of the standard
library than is required of a freestanding implementation.
The compiler runs on Windows95/98/NT and can be invoked either through the
command line or used within the ZDS integrated development environment.
There are several language extensions supported in this version, including inter-
rupt functions and memory space accesses.
Figure 1 shows an example of the C-Compiler development flow.
