It's about 12.000 lines of code.
I am not sure how much has rotted away, I last touched it in
2021.
The relevant files would be:
the bytecode interpreter:
https://github.com/UplinkCoder/dmd/blob/newCTFE_2093/src/dmd/ctfe/bc.d
the visitor that builds the bytodecode:
https://github.com/UplinkCoder/dmd/blob/newCTFE_2093/src/dmd/ctfe/ctfe_bc.d
as you can see by the branch name it was rebased on dmd 2.093.
so that's a few versions old now.
My word! I wonder how difficult it would be to maintain that if
it actually got merged into dmd. Do you remember what parts of
it were left unfinished?
I do not know on the top of my head.
I remember some math was not interpreted correctly.
Though after I stopped working with D I never went back to look.
As far as I know Max Haughton has tried to rebase it on master
and improve it but I have not heard from him about that.
I won’t get my hopes up for one person to rebase 12k lines
through 14.5K commits. It’s simply not feasible. I think a
larger community effort would be required to successfully
resurrect this implementation; although I am perhaps foolhardy
enough to try it myself…
The code is rather self contained.
I usually don't rebase but I simply copy the files from the ctfe
directory into the master checkout do what I can to make it
compile and then commit them as new files.
The history has been lost a long time ago already.
The only change to existing files should be in dinterpret.d where
I hook myself into the existing evaluator.
