LLVM 2.4
|
||||
~~~~~~~~
|
||||
|
||||
LLVM 2.4 is currently in progress. There are incompatible API changes
|
||||
from LLVM 2.3. The latest release of llvm-py will _not_ compile against
|
||||
it.
|
||||
|
||||
The llvm-py SVN has a branch called
|
||||
http://code.google.com/p/llvm-py/source/browse/#svn/branches/llvm2.4[llvm2.4],
|
||||
which attempts to track the changes happening in LLVM 2.4. There are
|
||||
however, some caveats:
|
||||
|
||||
- There are no releases from this branch.
|
||||
- When LLVM 2.4 is released, then these changes will be merged to main.
|
||||
From then on llvm-py will support LLVM 2.4 and no longer LLVM 2.3.
|
||||
- This branch is not religiously kept up-to-date with the changes
|
||||
happening in LLVM SVN. Therefore, it may not work for you, but might
|
||||
still be worth a try.
|
||||
|
||||
llvm-py can be checked out from this branch like this:
|
||||
|
||||
-----------------------------------------------------------------------
|
||||
$ svn co http://llvm-py.googlecode.com/svn/branches/llvm2.4 llvm-py-2.4
|
||||

|
||||
|
||||
