/* Leave this field blank. So the memcpy() is not defined, and this will
|
|
automatically pull in the default C definition of memcpy() from
|
|
../../string/memcpy.c. No need to include this file explicitely.
|
|
The lib_a-memcpy.o will not be generated, so it won't replace the default
|
|
lib_a-memcpy.o which is generated by ../../string/memcpy.c.
|
|
See the commands in configure.in and Makefile.am for more details.
|
|
|
|
However, if we need to rewrite this function to be more efficient, we
|
|
can add the corresponding assembly code into this field and change the
|
|
commands in configure.in and Makefile.am to allow the corresponding
|
|
lib_a-memcpy.o to be generated.
