newCTFE Status Janurary 2018

[Stefan Koch]

Hi Guys,

I've just done a small refactoring which I have been putting off 
for a while now.
It should greatly help with reducing ABI bugs, and it cuts the 
dependencies between the DMD-dependent and the independent parts 
of newCTFE.

Furthermore I fixed handling of 64bit values which where 
truncated to 32bit in some cases.
I've found those while working on ctfe-able float-to-string 
conversion.

However there are still many bugs which can crash newCTFE or even 
worse, make it produce wrong output (most of those are related to 
classes and vtbl-handling).

I expect it'll take me multiple full-time days to make 
significant progress on the vtbl issues. Because first I'll have 
to get debug-system into shape. It only really works if there is 
just one function in the context being compiled, as virtual 
functions by definition require multiple functions to live in the 
compilation context, it makes the debug-system useless .... sigh.

Unfortunately my time budget is pretty tight this and the 
following months as I am also preparing a Dconf presentation.

Let's see how far I can get during the next weekends.

Cheers,

Stefan
