The CFA is set by default to the stack pointer of the previous frame. So that is also how we can always restore the SP. This default aarch64 CFI rule is necessary on Fedora 28 with GCC8 to make the run-deleted.sh and run-backtrace-dwarf.sh testcases work. Signed-off-by: Mark Wielaard <m...@klomp.org> Debugging the test failure made it clear that the libdw1 in the archive will not be able to successfully walk the stack of processes built by gcc-8, i.e. this is a regression in runtime functionality. I don't know if any of the revdeps of libdw1 depend on this but it seems at least possible and the patch to fix all this is pretty simple so my inclination is that this meets the threshold for an SRU. [test case] Build the package on arm64. [regression potential] The patch is small, fairly (given the general level of hairiness around here) simple and only affects the functionality that is currently broken. There's always the chance that building with a new toolchain will introduce new problems, but there's not much we can do about that.
