[Pkg-pascal-devel] Bug#1061418: castle-game-engine: please add support for loong64

[Michalis Kamburelis]

Hi,

(Upstream of CGE here.)

For a new architecture, we need to have FPC (our compiler) with the
appropriate support for the architecture first.

- And at least upstream FPC 3.2.2 doesn't have this support (the CPU
isn't listed in
https://gitlab.com/freepascal.org/fpc/source/-/blob/fixes_3_2/packages/fpmkunit/src/fpmkunit.pp?ref_type=heads
).

- Only FPC from GitLab (not yet released) has this, and it is called
"loongarch64" (see
https://gitlab.com/freepascal.org/fpc/source/-/blob/main/packages/fpmkunit/src/fpmkunit.pp
). I don't know whether the support is considered stable or not.

- The FPC in Debian (
https://packages.debian.org/sid/fp-compiler-3.2.2 ) isn't released for
this architecture.

So, we need FPC to support this architecture (in some stable way), and
we need this FPC to be packaged in Debian, first.

Then adding it to CGE will be easy :)

- Once the FPC (at least packaged in Debian) has this supported, then
CGE unit ToolArchitectures ( tools/common-code/toolarchitectures.pas )
should be extended, to add a new enum to TCPU type.

- Extending the ToolDebian", as the attached patch does, is also nice
(but optional, it's only useful for `castle-engine package
--format=deb` to create DEBs of your games for new architeture; it's
not necessary to just build applications for new architecture).

- The attached patch just adds "loong64: Result := 'loong64';" to
"ToolDebian" but I don't think it can compile right now -- it
certainly doesn't compile with FPC 3.2.2 upstream.

Regards,
Michalis
