freeldr

[Timo Kreuzer]

Hi,

I'd like to change the Vtbl based architecture of freeldr into a normal 
function call system.
Currently we have stuff like

#define MachHwDetect()                MachVtbl.HwDetect()
     MachVtbl.HwDetect = PcHwDetect;

This is IHO simply useless, since these functions don't change. I 
suggest simply renaming PcHwDetect to MachHwDetect and do that will all 
of those and get rid of the MachVtbl.

Any objections?

Regards,
Timo

[Alex Ionescu]

I wrote this exact same request 3 years ago and Brian said no :)

Best regards,
Alex Ionescu

Again, please cite your sources Alex...

I'm pretty sure you were the one who suggested this vtable system in the
first place, for at least some parts of the FreeLoader code anyways, because
I didn't write it. But it does have some usefulness in places such as the UI
code where, depending on the platform, it does take a different code path,
and multiple code paths are valid options to be compiled in and parsed at
runtime depending on the .ini file.

In any case, please stop adding useless comments like this unless you intend
to bring up the original points of objection along with it. A simple "I
agree with the proposed change" would have sufficed here, and I'm tired of
going the rounds with you over conversations that never took place.

Please see the continuation of that *older* thread here:

http://www.reactos.org/pipermail/ros-general/2005-November/001987.html

And here, where you suggest using a vtable system instead of your original
idea:

http://www.reactos.org/pipermail/ros-general/2005-November/001988.html

And finally:

http://www.reactos.org/pipermail/ros-general/2005-November/001991.html


It's obvious from these threads that originally there was some confusion as
to what was going to be removed. After discussing it, we both came to
agreement. It's fine if you want to change your mind. Just please stop the
finger pointing at me.

I'm not opposed to removing the dead weight, especially in areas where
vtable like abstraction is not helpful. OTOH, there may still be some places
where a vtable like system is useful, and so the vtable stuff should be
removed carefully so that we don't lose any functionality in the process.

The only reason I argued for a v-table is because of the brokenness of
the old code duplication.

My original goal was to remove the code duplication/waste.

Timo wants to remove code duplication/waste as well.

Anyway, if you agree with removing useless code, that's great.

Alex Ionescu

What about those functions which do change?

What functions do change?
Its compiled for one achitecture explicitly. we don't need to support 
arm, when we compile for x86.
Or am I missing something?

What about XBOX which has its own functions (XboxHwDetect too)? IIRC it's  
x86 too.

[Alex Ionescu]

The only thing it would be useful for is on ARM, to build one FreeLDR
for all SoCs -- but I think right know it's built per-SOC anyway, so
the VTABLE is useless.
