I hope to post my question on the correct group. If it's not the case,
please direct me to a more relevant one.
I'm looking for a way for a compiler to build a DWARF information that
indicates a data storage located at a constant offset from the current
CFA. I don't see such a feature in the standard.
Here's some context : during a function prolog, many pushes are done
to save registers. For the moment, the compiler references arguments
with an offset from stack pointer, but he must emit a new location
information for each push in the prolog. It would be very convenient
to say instead "Arg1 is at offset x from the current CFA". As the CFA
is constant during the function, this declaration would be sufficient
during register save.
If someone has another idea...
