[#6718] Optimize the EEPROM functions
105
* Optimized functions:
114
* New devices supported:
123
- Signature API added in <avr/signature.h>.
125
- All functions are now placed in the .text.avr-libc section, and the
126
floating point functions are placed in the .text.avr-libc.fplib section. This
127
allows the user the ability to relocate all avr-libc routines to a different
128
address using a custom linker script.
130
- EEPROM functions are rewriten. Now they are pure asm functions with
131
tuning for each device individually. The reading of long word or block
132
is speed up. New functions for floats are added. The group of 'update'
133
(burn only different bytes) functions is added. A set of Avr-libc bugs
136
- The port/pin assignments of the HD44780 LCD controller in the
137
stdiodemo example can now be distributed across more than a single
138
AVR port. The only remaining requirement is that all data bits
139
are assigned to a single port in ascending order.

169
[#25645] xmega header files broken #defines
170
[#25723] Realloc corrupts free list when growing into the next free item
172
* Optimized functions:
173
cos, sin, tan: minor in space
174
sqrt (and callers: acos, asin and hypot)
176
* Contributed Patches:
177
[#6649] sqrt.S in libm changes
178
[#6720] FAQ update. Add EEPROM section, baud rate section. Correct spelling.
180
* New devices supported:
198
A sleeping BOD API was added to <avr/sleep.h>. This allows you to disable
199
the Brown Out Detector (BOD) before going to sleep, thereby reducing
202
The note about signbit() implementation is removed from documenatation.
203
The reason is that the GCC can replace it with inline code and the
204
nonzero value is unpredictable in such case.
206
*** Changes in avr-libc-1.6.4:
210
[#24762] 1.6.3 wdt.h compile-time bug
214
The Postscript documentation build has been removed in favour of
215
building only the PDF (and HTML and man page) versions. PDF offers
216
the same printing quality as postscript at a smaller file size.
217
This also works around a bug in doxygen 1.5.7 where it appears to
218
be no longer possible to set GENERATE_HTML = NO.

. The maximum quantity of conversions now is limited (255).

- EEPROM functions are rewriten. Now the base procedures (eeprom_read_byte
339
and eeprom_write_byte) are inline: they are evaluated at compile time
340
of user program. This gives a possibility to add support for new AVR
341
arhitectures very simply. Also this fixes Avr-libc bug #21410. New
342
functions for 32-bit words are added.

200
the same printing quality as postscript at a smaller file size.
201
This also works around a bug in doxygen 1.5.7 where it appears to
202

stdiodemo example can now be distributed across more than a single
221
AVR port. The only remaining requirement is that all data bits
222
are assigned to a single port in ascending order.
224
- Added support for avrtiny10 architecture, to support the ATtiny10 Family.
226
- Added new headerfile: <avr/cpufunc.h>; currently contains _NOP() and
229
- The twidemo can now optionally address 24C32 and larger EEPROMs
230
that require 16-bit word addressing.
232
- Add a "memory barrier" to the cli() and sei() macros.
