LLVM 3.2 Support
LLVM 3.2 is out as of mid December. We need to update the backend to support it.
There seems to be a number of new bugs due to the change.
With LLVM 3.1 we get the following testsuite failures:
OVERALL SUMMARY for test run started at Mon Jan 14 21:42:32 PST 2013
3552 total tests, which gave rise to
13164 test cases, of which
0 caused framework failures
11606 were skipped
1515 expected passes
23 had missing libraries
15 expected failures
0 unexpected passes
5 unexpected failures
Unexpected failures:
* codeGen/should_run cgrun044 [exit code non-0] (optllvm)
* concurrent/should_run 367_letnoescape [bad exit code] (optllvm)
* numeric/should_run arith005 [bad stdout] (optllvm)
typecheck/should_compile tc226 [exit code non-0] (optllvm)
typecheck/should_compile tc235 [exit code non-0] (optllvm)
Where the failures marked with '*' are unique to the LLVM backend.
With LLVM 3.2 we get the following:

Where failures marked with '*' are unique to the LLVM backend and failures marked with '**' are unique to LLVM 3.2 relative to 3.1.
I believe bootstrapping with LLVM also fails now. However, that may be due to the change to the new-code-generator, and not of LLVM 3.1 -> 3.2. I'll create a separate ticket for that.
NOTE: These test suite results were all generated on Mac OS X 10.8.
