This chapter explains the emulation library and the ANSI library included in the S1C17 Family C Compiler
Package.
7.1 library Overview
Briefly described below are general aspects of the libraries supplied with this package.
7.1.1 library files
The libraries comprise the following components:
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/sift functions, and
long long
-type addition/subtraction functions.
libgccM.a
Emulation library (supports coprocessor multiplication instruction)
This provides the same functions as libgcc.a, but uses multiplication coprocessor
instructions internally. In a model supporting coprocessor multiplication instructions, this
library can be linked in place of libgcc.a.
libgccMD.a
Emulation library (supports coprocessor multiplication, division, and remainder
instructions)
This provides the same functions as libgcc.a, but uses multiplication, division, and
remainder coprocessor instructions internally. In a model supporting coprocessor
multiplication/division/remainder instructions, this library can be linked in place of libgcc.a.
libstdio.a
Simulated I/O library
Provides the ANSI C library initialization function (see Section 7.3.3) and lower-level
functions for inputs/outputs.
The libraries are installed in the following separate directories for each memory model.
\EPSON
\gnu17
\lib
\24bit
24-bit (16MB) memory model libraries
libc.a
libgcc.a
libgccM.a
libgccMD.a
libstdio.a
\16bit
16-bit (64KB) memory model libraries
libc.a
libgcc.a
libgccM.a
libgccMD.a
libstdio.a
Link the 16-bit libraries with the application program when the
-mpointer16
option is specified in the C
compiler and assembler.
