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.
