I recently attempted to use the -HC
generated dmd/frontend.h to build LDC and discovered it doesn't work:
So far I have fixed:
- redefinition of
size_t
- appending of _ to C keywords (to the disgruntlement of Iain), so that the tokens enum work with clang
Still to do:
- generate
#include <stdarg.h>
whenva_list
is used - general issues of declaration order and forward declarations: some resolution is too eager resulting in subclasses being emitted before their base classes. other is not eager enough resulting in typedefs of templates not forward declaring their arguments ending up with
typedef Array<BaseClass* > BaseClasses not referring to a valid (i.e. prior) definition of
struct BaseClass`.
I'm currently in the weeds of resolving the order of declaration issues, but it is rather annoying and tedious, given DMD does not build on macOS. But before I lose the rest of my marbles trying to do that I thought I put out an invitation/request for help for anyone interested in learning a bit of DMD, given the success I had last time. Thanks already to Rikki for the header generation command!
I can provide an overview of what needs to be done along with a guided tour of the relevant bits of DMD and pull request reviews and so on.
Hit me up on the Discord if you are interested.
Thanks in advance,
Nic
