Using the ANSI C-Compiler
The eZ80Acclaim! C-Compiler is a conforming freestanding 1989 ANSI C implementa-
tion with some exceptions. These exceptions are described in “ANSI Standard Compli-
ance” on page 164. In accordance with the definition of a freestanding implementation,
the compiler accepts programs that 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 >. The eZ80Acclaim! compiler release supports more of the standard
library than is required of a freestanding implementation, as listed in “Run-Time Library”
on page 154.
The eZ80Acclaim! C-Compiler supports language extensions for the easy programming of
the eZ80Acclaim! processor architecture. The language extensions are described in “Lan-
guage Extensions” on page 135.
The following sections describe the various features of the eZ80Acclaim! C-Compiler:
•
