Somehow I have a feeling that the fix for one would also fix the other...
They are orthogonal issues.
I'd add the manual RIP addressing that was mentioned on the bugtracker recently
That's not a limitation. Not supporting absolute addressing on x86-64
would be a limitation.
(OT: is -Cg supposed to work on platforms where it is not set by default?).
I think it does, although I don't think it does anything on Win64 (as
its code is already position-independent by default).
For the original issue, since manually using assembler blocks makes things
complicated, is there a way to "strongly suggest" to the compiler that a
variable should become a regvar if the entire routine is pure Pascal? Something
like the (purely decorative) {register} comments in
/packages/pasjpeg/src/jdcolor.pas?
No, and I don't think it would be a good idea to spend time on
complicating the compiler with such functionality. Over time, such hints
become more of a burden than a gain (I believe all modern C compilers
completely ignore such hints).
