[llvm-dev] ELF string table access in backend

[David Blaikie via llvm-dev]

When you say "the string table" - are you referring to a particular
section? There can be multiple/any section that contains strings that can
be deduplicated by the linker (see debug_str for example) - and you can
create your own sections that have that kind of functionality if you like
(again, debug_str might be a goode xample to look at)
