Yes, this is important.

I have done patches to dmd myself. It is very quick and 
accessible.

I've never even tried to compile the others myself before, it is 
just intimidating. But out of curiosity, I tried to compile ldc 
just now.

git clone
git submodule init
cmake

OK, it took a full minute to get to this point, but that's OK, it 
is just setup.

make

... over a minute later:

/home/me/d/dev/ldc/gen/passes/GarbageCollect2Stack.cpp: In 
function ‘void RemoveCall(LLCallBasePtr, const 
{anonymous}::Analysis&)’:
/home/me/d/dev/ldc/gen/passes/GarbageCollect2Stack.cpp:446:35: 
error: conversion from ‘LLCallBasePtr’ {aka ‘llvm::CallBase*’} to 
‘llvm::CallSite’ is ambiguous
   446 |     A.CGNode->removeCallEdgeFor(CB);


yada yada yada.


I have no idea what any of this means, maybe the llvm version on 
my box (8.0.1) is too old, but with dmd, it USED to be that 
things would just work. It isn't *that* nice anymore, but it 
still isn't too hard. Way faster and much less scary = more 
likely to get new dev work done.
