Here goes my attempt to revive true PIC on ppc, starting with 83xx. This uses a a new gcc option(which I have just impl.) to add msingle-pic-base also save a lot of code:
Is my inderstanding correct that this is a private, all new gcc extension? Do you have plans to submit it upstream?
I appreciate your work, and I, too, would like to be able to do what this patch series seems to acchieve, but I think we should not add this to mainline when neither mainline gcc nor any of the "common" tool chains (say, OE/Yocto/LF, Linaro, CodeSourcery, ...) supports it.
-msingle-pic-base already exist for ARM. I impl. it for PowerPC too. I have submitted it upstream and I hope it will be accepted, it is ongoing but slowly as there are very few ppc maintainers.
