I'd like to know if there is any known project doing obfucated code
generation or software watermarking in LLVM.
The [obfucation/software watermarking] in machine instruction level usually
requires to insert dead code, constant "unfolding", computationally
intensive "opaque predicate", redundant calculation, duplicated
calculation,
etc, which all make the program inefficient.
But it seems to be possible to generate the code in an
[obfucated/watermarked] manner in the first place so that the code generated
in this way may not be so optimized but it's more efficient than applying an
additional (independent) obfucation pass later.
Alex.
