PLEASE read doc/INSTALL first for installation instructions. Changes: avr-libc-20011208 Add ATmega8 support (not yet enabled), thanks to Pieter Conradie. Add missing UCSR1C and fix INT_VECT_SIZE in iom128.h. ===== avr-libc-20011126 Changes to support ATmega128 (for now commented out in Makefile until the necessary changes are made to gcc and binutils) and make it easier to add other new devices (cleaned up gcrt1.S interrupt vectors), thanks to Peter Jansen <peter@smartcontainer.net>. Note: I haven't tested anything yet, other than it compiles ;) ===== avr-libc-20011029 Fix strtod() link error (fp_zero -> __fp_zero). Split eeprom.o into 4 object files (one function in each file). ===== Changes: avr-libc-20011007 Add avr-libc-reference.html document. Use "install -c" (ignored by GNU fileutils, needed on FreeBSD). Add isblank(). ===== avr-libc-20010821 Add atan2() and new atan(), thanks to Reiner Patommel. ===== avr-libc-20010717 Remember to update version in Makefile this time, this only matters for Makefile-win32 which has some known bugs, please help fix them. Update fplib license, now GPL + exception as in gcrt1.S and libgcc, now OK for proprietary applications too, thanks to Michael Stumpf. Fix strtod() whitespace handling, as in atoi(). More atoi() changes (now it's smaller) by Jochen Pernsteiner. ===== avr-libc-20010708 Add atan(), contributed by Reiner Patommel. Fix atoi() whitespace handling, reported by Jochen Pernsteiner. Alternative version of bit_is_set/bit_is_clear macros that can make better optimized code, suggested by Thomas Husterer. Fix bug in __fixsfsi for numbers <1.0, thanks to Michael Stumpf. Fix fplib/strtod.S and stdlib/atoi.S to not call __mulhi3, call a new optimized function __mulhi_const_10 instead. Use XCALL to call any external functions (might not be reachable for RCALL on >8K devices). ===== avr-libc-20010701 Add a few more asm string functions, thanks to Reiner Patommel (atoi, strcasecmp, strcasecmp_P, strcat_P, strncasecmp, strncasecmp_P, strlwr, strrev, strupr), changed by me to use standard (glibc, BSD) instead of DOS (stricmp etc.) names. ===== avr-libc-20010616 Tested with gcc 3.0 20010526 and binutils 010609 snapshots. Add strstr() (in assembler), thanks to Jochen Pernsteiner. Fix fplib/asin.S (P3 value), thanks to Dean Ferreyra. Fix itoa() again... even tested it this time ;). Fix div() and ldiv() to call the new libgcc functions, too. Fix gnu/qsort.c to compile without <ansidecl.h>. Separate Makefile-win32 for now (patches welcome and probably needed, it's just that I don't want them to break the Linux/*BSD Makefile in subtle unexpected ways that only show up on the first "make install" so I didn't catch them), help needed from someone who is good at writing portable Makefiles as I'm not :(. Move README to doc/CHANGES as that's what it really is. ===== avr-libc-20010331 Updated itoa() to work with current CVS libgcc (use __udivmodhi4). Updated iotn15.h (ATtiny15 I/O registers defines). ===== avr-libc-20010303 Merged some Makefile changes for win32 support (don't ask me how it works :), thanks to Gunnar.Henne@gmx.de (http://combio.de/avr/). ===== avr-libc-20010211 Minor changes (there are no bugs :), added new parity_even_bit() macro. Now available from http://www.amelek.gda.pl/avr/ (the previous URL - http://www.itnet.pl/amelektr/avr/ - will be available for some time). ===== avr-libc-20001125 More fplib bug fixes (can't depend on r1 being 0 in fp_split, fixsfsi should correctly return 0 for very small numbers, dtostre fixes). Again thanks to Kovesdi Gyorgy. ===== avr-libc-20001118 Some fplib fixes (compare return values changed to match what GCC expects; fp_split does not set the "hidden bit" if exponent is 0). Thanks to Kovesdi Gyorgy <gkovesdi@gw.cdk.bme.hu>. Updated ATmega163 defines (iom163.h) now that the official datasheet is released. Added preliminary AT76C711 defines (io76c711.h). Added copyright information (doc/LICENSE), released the files written by me as public domain (they have always been open source, but the wording of the copyright was a bit unfortunate). ===== avr-libc-20000730 Added multilib support for latest CVS avr-gcc changes. Renamed gcrt1-*.o to crt*.o (unique on 8.3 filesystems). Many other changes. ===== avr-libc-20000514 Minor tweaks, _end_of_ram_ -> __bss_end in malloc (please test - I've never had to use malloc on AVR yet), added -mcall-prologues so big C functions are smaller (prologue/epilogue only pulled in from libgcc if any of these functions are used - in this case it is a win to compile everything else with -mcall-prologues too), made strtod() use libgcc prologue/epilogue instead of its own. ===== avr-libc-20000503 More optimized asm string functions, more gcrt1.S hacks, added almost-IAR-compatible <ina90.h> and <pgmspace.h>. Please test with current CVS binutils and gcc - thanks. Marek ===== README for avr-libc-20000402 OK, approved :) - finally found some time and made some more cleanups, added early MCUCR and WDTCR initialization in gcrt1.S - for example, to enable WDT with maximum timeout and enable slow external SRAM, add these options to linker command line (via avr-gcc -Wl,...): --defsym __init_wdtcr__=0x0F --defsym __init_mcucr__=0xC0 Marek ===== README for additions / changes in avr-libc-20000207 as compared to avr-libc-20000201 which have not been tested or approved by Marek Michalkiewicz yet. These additions were done with the Win32 port of avr-gcc. Thus Linux users may have to change CR/LFs to CRs tune the Makefile to their needs Makefile: The new Makefile is needed to build all the additions to the lib. I tried to make it compatible with both Linux and Win32. Mareks original Makefile has been renamed to Makefile.orig. libm: Michael Stumpfs FPlib3.0 ported to avr-as Michael Stumpfs strtod function ported to avr-as but not tested yet libc: Michael Stumpfs ctype routines ported to avr-as non-ANSI C standard additions: dtostre (stdlib.h, libm.a) largely rewritten, Unix-like itoa (stdlib.h, libc.a), Windows / OS2-like changes to macros.inc added FARCALL (rcall / call) in analogy to VECTOR (rjmp / jmp) changes to progmem.h disabled #define PRG_RDB(addr) __elpm_inline(addr) because of too many complaints by mega103 users. If you use > 64kB program memory, try experimenting with __elpm_inline directly. Michael Rickmann <mrickma@gwdg.de> ===== README for avr-libc-20000201 This release fixes a few little bugs in the previous release. Most important: should work on ATmega103 now - gcrt1.S uses "jmp" instead of "rjmp" to jump to main(). ===== README for avr-libc-19991224 This release requires the latest avr-binutils and avr-gcc versions. Use of AVA assembler and linker is no longer supported (sorry, right now I'm extremely busy and backward compatibility was too much work - when finished, everyone would have been using binutils for years anyway :). Warning: this is work in progress. Not all features of previous avr-libc releases are supported yet: - fplib (needs to be ported to binutils first) - early MCUCR (required for external SRAM) and WDTCR initialization - optimized asm string functions (slightly larger/slower C versions available for now) - anything else I forgot? If you need support for AVA and/or any of the missing features, please use the older avr-libc-19991010 release, or help me by sending patches to implement features you need. Installation instructions are in doc/INSTALL. I have tested this version a little with AT90S8535 (used in the project I'm working on). Please test it more. Suggestions, bug reports, patches and new code are welcome. Thanks! Marek Michalkiewicz <marekm@amelek.gda.pl>
