I've just pushed an updated and rebased version of the tree: - Split the large "jit infrastructure" commits into a number of smaller commits - Split the C++ file - Dropped some of the performance stuff done to heaptuple.c - that was mostly to make performance comparisons a bit more interesting, but doesn't seem important enough to deal with. - Added a commit renaming datetime.h symbols so they don't conflict with LLVM variables anymore, removing ugly #undef PM/#define PM dance around includes. Will post separately. - Reduced the number of pointer constants in the generated LLVM IR, by doing more getelementptr accesses (stem from before the time types were automatically synced) - Increased number of comments a bit
There's a jit-before-rebase-2018-01-29 tag, for the state of the tree before the rebase.
If you submit the C++ support separately I'd like to sign up as reviewer and get that in. It's non-intrusive and just makes our existing c++ compilation support actually work properly. Your patch is a more complete version of the C++ support I hacked up during linux.conf.au - I should've thought to look in your tree.
The only part I had to add that I don't see in yours is a workaround for mismatched throw() annotations on our redefinition of inet_net_ntop :

This might be better solved by renaming it to pg_inet_net_ntop so we don't conflict with a standard name.
