[Qemu-devel] [PULL 4/7] target-arm: A64: Print ELR when taking exceptions

[Peter Maydell]

From: Soren Brinkmann <address@hidden>

When taking an exception print the content of the exception link
register. This is useful especially for synchronous exceptions because
in that case this registers holds the address of the instruction that
generated the exception.
