Good news. Thanks. Which distro/toolchain are you testing against?
When I worked on that branch I was using Fedora rawhide aarch64, which
only supports 64bit (no 32bit compat mode). So haven't been able to test
compat mode yet.
I am using the linaro LAMP image on the Foundation model from ARM,
as
described at:
-
http://www.linaro.org/engineering/engineering-projects/armv8
-
http://releases.linaro.org/latest/openembedded/aarch64/
Unfortunately the 32 bit support is not yet in so I am using a
statically built v7 binary for testing. The newer releases of Ubuntu
for AARCH64 are doing better in that respect, I have to give it a try.
Do you have an idea what/where to check for libdw compat support? I
just quickly browsed through the code and found the uses of the
ELFCLASS32/ELFCLASS64 macros interesting.
Do you need testing etc. in order to be able to merge the aarch64
branch? Please let me know!
Cheers,
Mark
