[llvm-dev] linker adaptability ...

[kris via llvm-dev]

hello folks,

I'm working to add runtime updating of code to the OCaml compiler
which in its bytecode
guise presents no barrier because there is only one linker and it is
written in that language and
full control is available.
With native code on the other hand, there is reliance on the system
linker and I got completely
lost examining the GNU ld/dl library source code.
The prospect of understanding and modifying all possible linkers is
daunting to say the least.
It's finally dawned on me that LLVM might have some of what I need already.
Would you be kind enough to examine the following wish-list and
comment on it's current viability
with respect to the LLD project?

1. to load and link a set of object/archive files into an in-memory executable.
2. to track the memory allocations attributable to each contributing
object processed with a view to releasing them.
3. to maintain the symtable in-memory with a view to updating symbols
and re-patching the in-memory executable.
4. to reload an object file/archive member (or a new one) and process
it in accordance with 3.

No doubt LLD is not geared to any of this directly, but does the
library provide any support?
thanks in advance....
