[lwip-devel] [patch #6822] Patch places memory pools in separate arrays

[Simon Goldschmidt]

Follow-up Comment #6, patch #6822 (project lwip):

Oh, you mean you would place the extern definitions like the following into
cc.h?

extern u8_t __attribute__((section(".onchip_mem"))) memp_UDP_PCB_base[];

That would mean if it's not defined, there would be a linker error, wouldn't
it?

I'd prefer to define the sections (in lwipopts.h) and let LWIP_MEMPOOL()
somehow use these defines. That way we can have one define (all memp pools in
the same section) as well as the #ifndef fallback.

I didn't yet think about how to manage that, only I'd prefer this over the
cc.h idea (it's more like the rest of the config options).

> I thought you meant how (since you said how :-) ) more than where.

Well, I meant 'how' in terms of 'the attached patch doesn't show it' -
there's no note about cc.h in the patch! :-)
