sdcc是为51等小型嵌入式cpu设计的c语言编译器支持数种不同类型的cpu

--- 2006-03-21  Raphael Neider

Added device specific SFR definitions in libdev/.
From now on all projects should be linked not only with
libsdcc.lib but also with pic$(ARCH).lib where ARCH is
something like p16f877.

Generic pointer support routines and additional arithmetic halpers
have been added to the library.

Although the compiled library should be portable across (all?)
pic14 devices, I recommend selecting the desired target chip
by setting the ARCH variable to the desired target chip in
  - Makefile.common	(AFTER having run ./configure)  OR
  - Makefile.common.in	(BEFORE running ./configure)
in order to maximize performance (smaller devices ignore
BANKSEL directives, i.e. updates to the IRP bit).

The pic14 library is split into several parts:

* common part
  The common part reuses the (hardware independant) sources found 
  under device/lib/ (currently not used).
* pic14 specific part
  The pic14 specific library routines are found in subdirectories of
  device/lib/pic/ and provide specialized implementations better
  suited for the pic14 architecture and additional functions not
  found in (or not reused from) the common sources.
* device specific part
  This part is planned to support specific I/O sub-devices not
  common to all pic14 chips. This part is currently absent...

The SDCC/pic14 library has been created by
	Raphael Neider <rneider AT web.de> (2005)

It is currently maintained by
	Raphael Neider <rneider AT web.de>

The pic14 and the device specific parts (whose sources are found
in device/lib/pic/) are to be licensed nuder the terms of the
GNU Lesser General Public License (LGPL). See COPYING for details.
The sources from the common part are licensed as indicated in each
file.

Requests for enhancements, additions or modifications should be posted
at the SDCC user's or developer's mailing list or directly be sent to
the current maintainer of the library as indicated above.
