5 Library
This chapter explains the emulation library and the ANSI library included in the S1C17 Family C Compiler Package.

5.1 Library Overview

Briefly described below are general aspects of the libraries supplied with this package.
5.1.1

Library Files

Libraries are provided for each compiler version.
libc.a
ANSI library
Provides ANSI standard functions.
libgcc.a
Emulation library
Provides single-precision (32-bit) and double-precision (64-bit) floating-point functions including arithmetic
operations, comparison and type conversion, integer multiplication/division/shift functions, and long
long-type addition/subtraction/shift functions.
（libgccM.a, libgccMD.a, libgccMD2.a）
These provide the same functions as libgcc.a for gcc3.
Different models are supported depending on coprocessor instructions.
libstdio.a
Simulated I/O library
Provides the gcc3 ANSI C library initialization function and lower-level functions for inputs/outputs.
libg.a
Debugging library
Provides support functions for the gcc4 debugger.
The gcc3 libraries are installed in the following separate directories for each memory model:
\EPSON
\GNU17V3\gcc3
\lib\24bit
\lib\16bit
The gcc4 libraries are installed in the following directories corresponding to the coprocessor specifications and memory model:
\EPSON
\GNU17V3\gcc4
\lib\24bit
\lib\16bit
\lib\M\24bit
\lib\M\16bit
\lib\MD\24bit
\lib\MD\16bit
\lib\MD2\24bit
\lib\MD2\16bit
Link the 16-bit libraries with the application program when the -mpointer16 option is specified in the C compiler and assembler.
