Assembly Procedure calls

Assembly Procedure calls

[J.S.Souza]

What is required for calling procedures using GAS?  Do I have to pay 
attention to far / near calls?  Also, do I need to pay attention to 
realigning the stack or anything else?  I noticed in other peoples programs 
that have procedures in the main file that they push the %edi register - 
what's this for?   Also, what is needed if I put the procedures in another 
file - do I need to declare things as EXTERN and so forth?  How about 
assembling the file - are there options I need to pass to 'as' and 'ld'?

Linear memory

[Frederic Marmond]

hi all,

I'd like to access to a memory area on a mtd device, without having 
compiling the mtd support in the kernel.
(read a firmware info, on a embeded environment => kernel as small as 
possible)
Is there any isue?

I mean:
is the device mapped anywhere, or is it really invisible, if i don't 
compile the mtd support?
If it is visible (how can i check that point?) do you know if there is 
any way to access it (like in flat mode, by a largest descriptor or 
something...)?


thanks for answers!

Fred
