llvm dev - Apr 2010 - [LLVMdev] Uninstalling TOT to use a branch release

Hello everybody,

I have been puzzling over how to uninstall the SVN Head release of LLVM for
compatibility with llvm-gcc 4.2-2.6.  Our project is based on 2.6 of LLVM but I
needed to install TOT to check if a bug was ours or had been fixed in the latest
LLVM.  Now that the bug is fixed, I need to go back to LLVM 2.6.  I used CMake
to build TOT on MacOSX 10.5.x and there is no "make uninstall" option.
When I try to build LLVM 2.6 it seems to skip over some of the files during the
"make install" stage and llvm-g++ doesn't do its --emit-llvm
functionality as a result.

If you need more information about the error I get or what the project I'm
working on is, I'll be watching the list carefully for replies.

Thanks for your time,

--Sam

Still unresolved.

The exact error message I get each time I try to use llvm-g++ is
'unrecognized command line option "-emit-llvm-bc" '.  I've
tried reinstalling both LLVM and LLVM-GCC using MacPorts.  I've searched the
archives of the mailing list.  Does anybody know what files need to be removed
from a SVN head install of LLVM to make my Mac running MacOSX 10.5.x work with
version 2.6 again?

I don't have an answer to your question other than the obvious but 
unsatisfactory answer of looking manually in the install directory for 
all LLVM tools and libraries.  It shouldn't be that bad, but I 
understand that it is less than ideal.

I suppose another option is to install LLVM 2.6 into a different 
directory and set your $PATH to search that directory first.  That 
should at least verify that your problem stems from having non-LLVM 2.6 
components lying around.

Moving to your other issue, are you sure that -emit-llvm-bc is the right 
option name?  Isn't it just -emit-llvm?  I seem to recall reading about 
an -emit-llvm-bc option but then discovering that the document was wrong.
