This chapter explains how to use the
xgcc
C compiler, and provides details on interfacing with the assembly
source. For information about the standard functions of the C compiler and the syntax of the C source programs,
refer to the ANSI C literature generally available on the market.
6.1 functions
The
xgcc
C compiler compiles C source files to generate an assembly source file that includes S1C17 Core
instruction set mnemonics, extended instructions, and assembler directives. The
xgcc
is a gnu C compiler in
conformity with an ANSI standard. Since special syntax is not supported, the programs developed for other types of
microcomputers can be transplanted easily to the S1C17 Family.
Furthermore, since this C compiler has a powerful optimizing capability that allows it to generate a very compact
code, it is best suited to developing embedded applications.
This C compiler consists of three files:
xgcc.exe
,
cpp.exe
and
cc1.exe
.
The
xgcc
is based on the C compiler of Free Software Foundation, Inc. Details about the license of this compiler
are written in the text file "Copying GNU", therefore, be sure to read this file before using the compiler.
This C compiler has passed the compiler evaluation provided as a service by Japan Novel Corporation.
Of bugs detected during the evaluation, those violating C compiler restrictions are described in “\gnu17\doc\
release_history_j.pdf” and Section 6.7, “Known Issues.” Refer to these documents for detailed information.
