We're trying to retarget the Pro64 for another processor than IA64.
We noticed that the WHIRL tree is built in parallel to the rtl
of GCC. We do not really need the rtl but in order to build the compiler
needs to provide the gnu/config/TARG/TARG.md file based on which some
rtl structures are generated.
Question: what are the informations in the gnu/config/ia64/ia64.md
for the Pro64 WHIRL generation (if any). Would it create a problem if we
used the ia64.md in hope that the rtl is entirely dummy here ?
