--- Comment #6 from rrorden at ptc dot com ---
I understand now. Thanks for the explanation. For now I have found a workaround
for my problem with a large aot-compiled object by custom-naming the ELF
sections and using a linker script to order those sections first in the output.
But I think this will only work until the object gets big enough that calls to
external functions are over 128k away. If I implement the equivalent of
-ffunction-sections, would this cause the image expansion problem for A53
erratum you mentioned? Is it possible to keep track of the accumulated size of
the input sections and emit a shared veneer sub-section only when it is about
to exceed 128k? Then you only have to align to a 4K boundary every 128k.
