eZ8 C-Compiler
Introduction
The eZ8 C-Compiler is an optimizing ANSI C-
Compiler. The eZ8 C-Compiler meets ANSI’s defi
-
nition of a freestanding implementation (code can
be developed for another machine), with the excep
-
tion that doubles (object types) are 32 bits. In
accordance with the definition of a freestanding
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> and
<stddef.h>. This release supports more of the
standard library than is required of a freestanding
implementation.
The compiler runs on the Windows

Win98
Second Edition, WinNT 4.0 Service Pack 6,
Win2000 Service Pack 3, WinXP Service Pack 1
operating systems and can be invoked either
through the command line or within the ZiLOG

ronment. There are several language extensions
supported in this version of the compiler, including
interrupt functions and memory space accesses.

piler development flow.
