 Hi Fathi,

 I'm now dealing with a problem related to libunwind support on aarch64.
 Could you please tell me why '--enable-debug-frame' is needed for
 aarch64?

After asking to the TC guys, AArch64 doesn't default to debug-frame usage yet.
But as it is the only unwinding mechanism implemented in it, it would
make sense to make it the default.
They're going to give a deeper look to it, and propose a patch if needed.

tcmalloc >= 2.4 has support for arm64. We've upstreamed support a year ago.
If you use latest release (2.5), it should work without issues.

Admittedly, I haven't checked recently and things may have progressed upstream.
I'm going to double check with our toolchain guys.

This would enable .debug_frame instead of .eh_frame for unwinding.
AFAICT it was only
needed on arm ( 32bit) not sure you need this on aarch64

libunwind needs to be configured with --enable-debug-frame to prevent a
linkage error.
Note: --enable-debug-frame is automatically selected on ARM32, not on ARM64.



Thanks.
We dropped the configuration flag and don't see any linking/linkage
problems yet. Can you be more specific about the problems encountered?

Our goal is to make tcmalloc from gperftools work on ARM64.
