libdwarf seems to have dissapeared from SGI's website. The last known location of libdwarf was http://reality.sgiweb.org/davea/dwarf.html, but http://sgiweb.org no longer seems to be accessible. There appears to be an alternate implementation of libdwarf at http://sourceforge.net/apps/trac/elftoolchain/wiki/libdwarf but it seems like it houses more than what I currently require. To get around the situation, I extracted libdwarf from hpctoolkit-externals [http://hpctoolkit.org/software.html].
Today I learnt that all of what I had studied about segmented memory while programming the 8085 and 8086 microprocessors was useless. Well, to be precise, segmentation has been almost abandoned in 64-bit x86 processors and the operating systems that run on it. And if you, like me, were trying to wrap your head around the complexities and inconsistencies that surround memory mapping on 64-bit processors in Linux (and partly, Windows as well), then here's something that might help.
Need I say more?
