Obviously there would have to be some arch dependent conditional changes, but I was hoping that someone with a clue about libbfd, could provide some hints as to where else to look for more info on what other changes might be required, or confirmation that this is object oriented enough to mainly just work with some additional tweaks. I also found out, and found a mailing list post that confirmed, that gdb gcore also does not work to generate a core image on Windows, as that was my next place to look. So it looks like gdb gcore for x86 could be implemented by adding the dumper code. The question is where to ask or look to figure out what Windows x86_64 needs over what Windows x86 needs, and add that to both gdb gcore and dumper, as gdb seems to handle debugging and debuginfo fine. If this could be derived from say, Cygwin ld libbfd calls, or the diffs between x86 and x86_64 ld.bfd calls, or nm, objcopy, objdump etc. diffs, I could look at doing that. I'm not sure I'd want to have to understand in detail how Windows puts its exes together to get started. -- Take care.
