Subject: <s>Set up the LLVM context and optimise the module
X-Git-Url: http://git.lukelau.me/?a=commitdiff_plain;h=8386b89c4a269b7ba16a3a26517894c33393a795;hp=8386b89c4a269b7ba16a3a26517894c33393a795;p=kaleidoscope-hs.git

<s>Set up the LLVM context and optimise the module

Now that we have some LLVM IR generated, we can run PassManager on our
module to get a bunch of neat optimisations on it. Try it out with 3 + 2
to see some constant folding.
Note that the original tutorial uses FunctionPassManager which optimises
on a function per function basis: llvm-hs doesn't expose this yet (and
this is all using the legacy pass manager anyway), so for now we just
optimise the entire module at the end.
