The »objcopy« tool that comes with GNU binutils (called ++»avr-objcopy« in our case) has been designed for this kind of ++conversions, and the GNU binutils itself could already handle more ++than two dozens of different COFF file formats, so for most of the ++part, a common subset of COFF utilities could already be used. (COFF ++is a very old object file format that has been in wide use by end of ++the 1980s/beginning of the 1990s.) ++ ++There are two different file formats defined by Atmel, the original ++AVR COFF format, and a newer version that is understood by AVR Studio ++4.07 and above called AVR »extended« COFF. In order to provide an ++easy way to distinguish both, two different so-called BFD names have ++been chose within GNU binutils, coff-avr for the former, coff-ext-avr ++for the latter. (BFD stands for »binary filedescriptor« and is ++basically the central library of the GNU binutils suite that handles ++all the object file IO.) ++ ++In short, chose coff-ext-avr for AVR Studio 4.07 and above, and ++coff-avr for anything else (which includes AVR Studio 3.x, and VMLAB). ++The main differences are that the newer format can transport long ++filenames (so directory information will be retained), and has the ++option to debug struct types. ++ ++The tough part was to convert the stabs debugging information into the ++so-called native COFF debugging format, which is basically an ++extension of the symbol table that can usually be found in object file ++formats. Symbol tables provide a listing of names vs. object file ++sections plus addresses within that section, that can be displayed ++with the (avr-)nm tool. Now COFF has extended the meaning of a symbol ++by adding some debugging information to it within the symbol table. ++In contrast, the approach taken with ELF is to leave the symbol table ++as it is (the so-called non-debugging symbols), and add the debugging ++information in separate sections within the object file. Since the ++amount of information that can be transported by native COFF ++debugging, the approach to use (stabs) debugging information in ++separate sections has also been in widespread use with COFF on Unix ++systems, but unfortunately Atmel had chosen native COFF debugging ++information instead. ++ ++Fortunately, the objcopy tool already had implemented part of the ++task: the --debugging option was already there, and is meant to ++convert the debugging information from the input file into a generic ++internal debugging format, and from there into the debugging ++information required for the output file. So it was ``only'' that a ++COFF debugging generator needed to be written. (The source code for ++this converter alone is close to 100 KB, in almost 3,500 lines of C ++code...) ++ ++ ++The conversion from ELF/stabs to AVR COFF ++----------------------------------------- ++ ++The usage of objcopy to convert ELF/stabs debugging information into ++AVR COFF debugging information is (long lines wrapped with ++backslashes): ++ ++avr-objcopy \ ++ --debugging \ ++ -O ${FORMAT} \ ++ --change-section-address .data-0x800000 \ ++ --change-section-address .bss-0x800000 \ ++ --change-section-address .noinit-0x800000 \ ++ --change-section-address .eeprom-0x810000 \ ++ ${filename}.elf ${filename}.cof ++ ++where ${FORMAT} should either be "coff-avr" (COFF format that matches ++the older Atmel AVR COFF documentation, as understood by AVR Studio 3, ++early versions of AVR Studio 4, and also by VMLAB), or "coff-ext-avr" ++(current AVR »extended« COFF specification, as understood by AVR ++Studio 4.07; adds long filenames and structure debugging). There are ++some more options dealing with the mapping of debugging source file ++names for coff-ext-avr which i can explain later if you need this ++(coff-avr only supports 14-char filenames, so no source file directory ++information can be tranferred there). ++ ++In the WinAVR template Makefile, you can say »make coff« to get the ++resulting file ($(TARGET).cof) in the coff-avr format, and »make ++extcoff« to get it in the coff-ext-avr format. ++ ++There might be some warnings when you run the above, like ++ ++Warning: file {standard input} not found in symbol table, ignoring ++Warning: ignoring function __vectors() outside any compilation unit ++Warning: ignoring function __bad_interrupt() outside any compilation unit ++ ++Perhaps more of them if your avr-libc has been installed with ++debugging symbols (the default WinAVR installation strips debugging ++symbols from the installed library files). There should be no other ++warning normally. ++ ++Run it on your jobs, see if it works as expected. In particular, i'm ++interested in getting results for more complex datatypes, like arrays ++of pointers to function, or functions returning pointers to ++structures, and such. ++ ++ ++COFF woes ++--------- ++ ++When working with COFF files, keep in mind that it's fairly limited. ++Basically, you can cut it down to stating that native COFF debugging ++can only support anything that was already defined in the very first C ++implementation, the so-called Kernighan/Ritchie C. There wasn't a ++standard for C by that time, so the de-facto standard was what has ++been described by the creators of C, Brian Kernighan and Dennis ++Ritchie, in their book ``The C programming language''. ++ ++Anything that appeared later, starting with the extension by the ++so-called ANSI C (now called C89), is basically unsupported in COFF, ++because the debugging format has not been designed with extension in ++mind. Needless to say, this also includes any C99 or C++ extensions. ++ ++Also not supported in COFF are include files. So if you've got an ++include file that actually produces code (e. g. in an inline ++function), don't be surprised that the line numbers in the object file ++will come out as junk. ++ ++COFF tried to save space everywhere, so they defined line numbers as ++16-bit quantities. In order to not limit a single source file to 64 K ++lines, they then defined their line numbers relative to the beginning ++of a function. Thus, COFF line numbers can only exist inside ++functions, and since functions need an input file name, if we don't ++have one (as it can happen in some assembler files assembled with ++--gstabs), we are hosed. ++ ++Finally, even AVR Studio 4.07 implements only a subset of COFF ++debugging information. Currently still unsupported are bitfield ++structs, enums, and typedefs. Note that the binutils patch does ++support all of these features -- only AVR Studio cannot handle them. ++ ++ ++COFF file analysis using abr-objdump ++------------------------------------ ++ ++avr-objdump -g gives a nice pseudo-C code listing of the debug ++information contained in an object file. If you suspect any problems ++with the conversion of the debugging information, try first running ++this on both, the input ELF, and the output COFF file. ++ ++avr-objdump -t gives the raw COFF symbol table listing. It's not ++completely "raw" though, since AVR COFF has so many twists and ++abominations compared to the historic standard COFF, and in order to ++be able to use all the COFF infrastructure in GNU binutils, i'm ++"normalizing" most of this when reading the file (at the same boundary ++where the byte-swapping is handled inside binutils), and de-normalize ++it to the AVRisms when writing it. Thus, objdump -t shows the ++normalized internal form. ++ ++Should you ever need this, i'm happy to explain you in more detail, ++and give you both the current Atmel specs for AVR COFF, as well as a ++pointer to a generic COFF description. It'll be lengthy to explain ++that right now. ++ ++ ++Bug reporting ++------------- ++ ++If you suspect a bug, please make first sure that you've read and ++understood all of the above, in particular the limitations of COFF. ++Please also make sure that you don't just have a plain usage error. ++Remember that there has been a fair amount of alpha testing, so all ++the basic problems should have been shaken out by now. ++ ++Then, try breaking down what the bug might be. Use the avr-objdump ++tool as described above, to see what the debugging information in both ++files looks like. Obviously, they will never look identical (there ++are two many differences in the internal representation between stabs ++and native COFF debugging), but they should be similar. If ++avr-objdump -g produces the expected result but AVR Studio doesn't ++work the way you think, it's most likely not a bug in the conversion, ++but maybe either that the compiler gave incorrect information about an ++object to debug (i've seen situations where a variable got optimized ++completely away in a simple function, so obviously, the debugging ++information for it was wrong), or a problem in the debugger used (like ++AVR Studio). ++ ++Finally, try to make it reproducable. Don't send 500 KB entire ++project ZIP files. Keep in mind that i don't have Windows, and don't ++run AVR Studio -- so don't just make the assumption i could reproduce ++your problem. Please, break it down to the respective portion of the ++avr-objdump -t output (you can see the symbol name in the right ++column, use that for navigation), and send the portion of this dump ++that describes the problem. For a function, that »portion« starts at ++the symbol with the name of the function, and then goes from the .bf ++symbol to the corresponding .ef symbol. For a structure definition, ++it starts with the name of the struct, and goes through the .eos ++symbol. ++ ++So in order to send a bug report, please use the address ++ ++<avrcoff-bugs@uriah.heep.sax.de> ++ ++Depending on the time available, and the degree of your own ++investigation, i'll try to answer them. ++ ++ ++Known issues ++------------ ++ ++There are few remaining known issues with the generated COFF. ++ ++The so-called AUX entry pointerization is sometimes wrong. According ++to the COFF specs, all the .bf symbols should form a linked-list, ++where the "next" pointer in each of them points to the next .bf. ++There are similar issues for some other of these records. This should ++normally not upset the debuggers like AVR Studio because they don't ++care about it, and will be fixed anytime soon (but the fix is not so ++easy unfortunately). ++ ++There is a known and still uninvestigated issue where some bootloader ++code could not be debugged. ++ ++There is one issue with memory de-allocation that is not yet properly ++handled, which is merely cosmetical since when the objcopy tool exits, ++the memory will of course be freed anyway. ++ ++There are two known issues with the latest official (by now) version ++of AVR Studio 4.07's COFF parser. The first is that this parser used ++to assume a fixed section ordering instead of checking the COFF file ++header. Usually, gcc also emits the various sections in the order ++assumed by that parser (.text first, .data following), but under some ++circumstances, gcc could put .data first as well. With the buggy ++parser, this would make AVR Studio believe your variables were located ++in ROM. ++ ++The second issue is that AVR Studio until now didn't support the way ++gcc allocates the initialization data for initialized variables: they ++are not issued as part of the program code, but instead need to ++appended manually after the program code itself. (When preparing an ++Intel Hex file, this is usually done by specifying both, the .text and ++.data section in the call to avr-objcopy.) So in the end, AVR Studio ++was simulating with all the initializers still using 0xff as ROM ++contents. There is no fix for this behaviour for AVR Studio 3.x, ++and/or for older versions of AVR Studio 4.x (all released versions by ++now), and/or for other ELF->COFF conversion tools than the GNU ++binutils with the current coff-avr-patch. Starting with this patch, ++we have negotiated our own vendor ID in the extended AVR COFF header ++(0x9cc, mnemonic for "gcc"), and Atmel agreed to adjust their COFF ++parser so it also loads the contents of .data into the simulator flash ++after .text when it sees this vendor ID. ++ ++Both issues have been fixed internally in Atmel's sources, but by now, ++there is no official version of the updated COFF parser available yet. ++There have been rumours that they might release their own beta site to ++the public in order to test the updated COFF parser as well (which is ++just a DLL that needs to be replaced). ++ ++ ++Dresden, Germany, 2003-05-16 ++Joerg Wunsch +diff --git a/bfd/coff-avr.c b/bfd/coff-avr.c +new file mode 100644 +index 0000000..d02e933 +--- /dev/null ++++ b/bfd/coff-avr.c +@@ -0,0 +1,613 @@ ++/* BFD back-end for Atmel AVR COFF files. ++ Copyright 1990, 1991, 1992, 1993, 1994, 1995, 1999, 2000, 2001, 2003 ++ Free Software Foundation, Inc. ++ Created mostly by substituting "avr" for "i860" in coff-i860.c ++ ++This file is part of BFD, the Binary File Descriptor library. ++ ++This program is free software; you can redistribute it and/or modify ++it under the terms of the GNU General Public License as published by ++the Free Software Foundation; either version 2 of the License, or ++(at your option) any later version. ++ ++This program is distributed in the hope that it will be useful, ++but WITHOUT ANY WARRANTY; without even the implied warranty of ++MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
