RFA: Generation of additional sections after size_seg

RFA: Generation of additional sections after size_seg

[Kai Tietz]

Hello,

I am working on a patch to generate xdata/pdata section for x64. The
xdata contains offsets relative to the function entry, but it
recomments, that this offset has 1 byte size. If the offset is bigger,
then additional function entries have to be generated (chained
elements) to express this. This leads no to the problem, that I need
to have the .text section already sized to figure out what how
xdata/pdata has to be written. But when I add those sections after the
sizing (in write_object_file), the symbols aren't anymore resolveable.
At least I get always the message "internal error: fixup not contained
within frag".
Possibly somebody could give me a hint on how to solve this. Otherwise
I see no other chance to emit here intermediate content for the linker
and do the generation of those data there, but I would like to avoid
this (as it isn't standard anymore).

Cheers,
Kai

PS: I can post the patch I made so far, if somebody is interested in.

  Yes please.  I'll have some spare time to help while I'm waiting for
responses to the weak symbols stuff.

    cheers,

Hello Dave,
