@cindex arithmetic libraries

Code compiled with GCC may call certain library routines. Most of
them handle arithmetic for which there are no instructions. This
includes multiply and divide on some machines, and floating point
operations on any machine for which floating point support is disabled
with @option{-msoft-float}. Some standard parts of the C library, such as
@code{bcopy} or @code{memcpy}, are also called automatically. The usual
function call interface is used for calling the library routines.
Some of these routines can be defined in mostly machine-independent C;
they appear in @file{libgcc2.c}. Others must be hand-written in
assembly language for each processor. Wherever they are defined, they
are compiled into the support library, @file{libgcc.a}, which is
automatically searched when you link programs with GCC@.
