[llvm-dev] lld: order of object files to be put into executable

[Nicolai Hähnle via llvm-dev]

Hi Quolick,

the order of pages in an executable doesn't really matter in modern 
operating systems. The relevant parts of the executable are mmap()ed and 
loaded on demand.

Although, keeping related code together for locality could be an 
advantage (both at load times w/ readahead and in the TLB during 
runtime), so that's a more interesting question to pursue.

Cheers,
Nicolai
