[LLVMdev] Files to lib/System/Win32

[Reid Spencer]

Can we put this issue to rest?

I stated in a previous email that the interfaces that expose $HOME and /etc 
will be removed from lib/System. They will be replaced with a "getConfigFile" 
function that does the right thing on a given platform. If that means looking 
in the user's home directory or /etc/llvm on Unix, that's fine. If it means 
looking in C:\Program Files\LLVM\Config, that's fine too. The point I'm making 
is that exposing the notions of a system configuration directory (/etc) or a 
user's home directory ($HOME) are too low level for lib/System. What's really 
needed is platform-specific ways to find configuration files in standard 
places, regardless of what that standard is.
