[sdcc-devel] Array initializers

[Johan K. <joh...@id...>]

Hi, I couldn't withdraw the challenge ...

In SDCCast.c:InitAggregates(): If you now have the environmental variable
"TRY_THE_NEW_INITIALIZER" set, AND compile with -mmcs51 AND --model-large
AND have an initialized array in xseg, you can experience the new VERY
EXPERIMENTAL  way of how things COULD be done: memcpy cseg to xseg. This
certainly solves bug #453727.

Right now (under the pre-mentioned conditions) it emit's code in
SDCCast.c:initAggregates() WHICH IS A MORTAL SIN, I know, but hey: this is
experimental and won't hurt those who are not addressed.

The point is that I can't figure out how to generate ast's for the memcpy
call and insert it in the right place. Can use some help here.

Please tell me what you think.

Johan

P.S. This is not what I think is the optimal solution. Every var now uses
this whereas copying a special cseg to a <whatever>segment would be even
much more efficient.
