[Minios-devel] [UNIKRAFT PATCH v3 0/2] Add eh_frame and eh_frame_hdr to the linker script

[Vlad-Andrei BĂDOIU (78692) <vlad_andrei.badoiu@xxxxxxxxxxxxxxx>]

For the exception handling in C++ additional information must be
provided to the runtime environment that describes the call frames 
that must be unwound during the processing of an exception. 
This information is contained in the special sections 
.eh_frame and .eh_frame_hdr.

Changes from v1:
*) Removed the alignment between sections.
*) Adapted the section register from memory.h to the latest
changes in staging.

Changes from v2:
*) Solved checkpatch errors in /plat/xen/memory.c
*) Add the eh_fram and eh_frame_hdr in plat/kvm/arm/link64.lds.S
and plat/xen/arm/link32.lds
*) Increase de memory region count on plat/xen/memory.c from 5
to 7 (we have 7 sections now with eh_frame and eh_frame_hdr)
*) Changed the order in plat/*/memory.c to follow the order
from the linker script. Now the sections are registered after
the code section.
