Could you elaborate the reason of restricting only to ia64?
it's not needed by default on architectures other than ia64. only the unwinding
in gcc on ia64 uses the library by default. it's unused on all other archs.
The upstream describes on the platforms in
/usr/share/doc/libunwind7-dev/README.gz:
This is version 0.99 of the unwind library. This library supports
several architecture/operating-system combinations:
Linux/IA-64: Fully tested and supported.
Linux/x86-64: Works well.
Linux/x86: Works well, but C library is missing some unwind-info.
Linux/PARISC: Works well, but C library missing unwind-info.
HP-UX/IA-64: Mostly works but known to have some serious limitations.
Linux/PPC64: Newly added.
So, x86-64 looks reasonable for me. Moreover, the reason why I NMUed is that
google-porftools requires this library for x86-64 (amd64).
yes, but google-porftools doesn't have this high priority.
