C Compiler xgcc
Outline
This tool is made based on GNU C Compiler and is compatible with ANSI C. This
tool invokes cpp.exe and cc1.exe sequentially to compile C source files to the
assembly source files for the S1C17 Family. It has a powerful optimizing ability that
can generate minimized assembly codes. The xgcc.exe can also invoke the as.exe
assembler to generate object files.
