[LLVMdev] llvm-config "to do" list

[Eric Kidd]

Reid and I have identified a number of problems with llvm-config,  
which I'll be looking into this week:

1) llvm-config doesn't always pick up system libraries needed to  
link. This should be an easy fix, although it will require Makefile  
changes.

2) In-tree linking doesn't work. I'm not sure why out-of-tree linking  
with llvm-config works better than in-tree linking. I'll need to take  
a look a Reid's scripts.

3) Judging from Reid's bug reports, linking 'interpreter' doesn't  
seem to be enough to get the ForceInterpreterLinking() function. I  
have no idea what's going on here--this code was added after llvm- 
config was committed.

I want to get these issues sorted out in time for LLVM 1.7. For LLVM  
1.8, we can look into re-writing llvm-config as a C++ program (to  
remove llvm-config's dependency on Perl, allowing it to be used in  
the GCC build process).

Cheers,
Eric
