[Crash-utility] crash on x86_64: how to dump arg registers?

[Paul Sanders]

Hello all,

I'm trying to get myself ramped to using crash on x86_64.

In x86_64 there is no register stack and function arguments aren't
typically placed on the stack, therefore we aren't able to see the
function arguments in the bt -f output.

Is there a trick to dumping out %rdi, %rsi, %rdx, etc?

I hope this isn't too lame of a question. I'm just getting my toes wet
with x86_64 and kdump/crash.

Thanks in advance,
