Dear Joakim Tjernlund,
In message <OFF06E784F.A10A5A15-ONC12577B2.0065FB3C-C12577B2. 0066D69F@transmode.se> you wrote:
:), actually it wasn't that bad. Wolfgang nearly accepted the code even :)
Yes, I was really tempted because I do appreciate the value of such a feature.
Mainly, I had to wrap code that accessed global data with a LINK_OFF() function that calculated the offset and only in code that executed before relocation.
That was the part that gave me the creeps. It looked too much unreadable and error prone to me, especially as this is not only a one-time conversion but has to be kept in mind for all changes to related code.
Yes, that is a bummer. If one could convince gcc to do %pc relative addressing on strings/constant data the we would be in business I think. Anyone got gcc connections?
I'm still undecided, to be honest.
