Useful files, tools and links for Jaguar development in Development Posted August 11, 2014 · Report reply This what I meant indeed. But is .GPUMAIN addding all you need to allow code run perfectly from main ram ? I may be wrong and am not sure if I am quoting from the manual or recalling from a JFUK conversation with SubQmod but I believe it checks for and where necessary adds various NOPs required concerning pipelining around Jumps as well as checking/taking care of phrase(?) alignment requirements to make things easier for the programmer. Presumably you have tried PMing SubQmod at AA.
