Re: lua on ARM7

[bert <bestanf@...>]

Hi All,

Continuing on the LUA on ARM thread... I've been thinking how I could run a subset of LUA in under 32K, and fast enough for RT applications. What if :

    - we don't want to support the lua standard libraries 
    - we don't support dynamic memory allocation and leave out the garbage collector (so we need a special keyword to alloc all memory at boot time) 
    - we use int32 instead of float as number type
    - we don't support the local keyword or variables that were not explicitly allocated at boot time

what parts of the LUA source distribution would I need to run the VM on the ARM and what can I leave out? I looked in the lopcodes.h and lvm.c and didn't see special instructions for memory allocation .. but then I haven't thoroughly studied all of the LUA code. 

Thanks,
Bert
