I have been trying to find out right options to configure gcc to produce data and code relocatable code for mpc5xx. The -fpic -meabi -msdata=eabi -G10000 does code as relocatable but data is still absolute. -fpic is incompatible with -msdata=eabi so they can't be used at same time.
based on gcc documentations -msdata=eabi -G10000 should put data so long that it is smaller than valu give in -G option to relative to r2 or r3 but i have not suceeded to do it.
I have been using gcc for producing absolute code for PPC many, many years but now i have need to load dynamically code for non mmu PPC (mpc555). All examples that i have found uses static addresses. Also using google i have not found any answers.
I have tried many forums to find answer but i am still trying to find it. Also i am happy to get pointers to forums/places where i can continue my search.
