Re: [sdcc-devel] Array initializers

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

I continued my work on the aggregate (array AND structure) initializers.
What else should I do. I can't be of any help somewhere else.

Assuming you set the environmental variable TRY_THE_NEW_INITIALIZER to
something:

Global and local aggregate initializers are put into code space. From there
it is copied to where it belongs (only xseg for now) at either program
startup (for globals and static locals) or at every invocation of a function
(for non-static local's of course).
I considered a special segment that would prevent to initialize on a per
global-var, but that isn't worth it: it won't happen that often.

The next step should be to implement a _native_memcpy() that prevents the
use the generic memcpy() and would be even much more efficient, (see the
comments in src/mcs51/gen.c:gen51AggregateAssign() 1.88).

Please let me know what you think.

P.S. I only tested this with (multi dimension) arrays, not for structures
yet.
