Can gp register be used as ponter to GOT table for GOT-based PIC?

I find an issue about Embedded PIC at #128 (comment).

GOT-based PIC is a similar concept, but using GOT to implement PIC. For ARM chips, register R9 can be used as pointer to GOT, this is useful when trying to implment xip elf-loader, which will not load .text and .rodata into ram. We implment linux support for CortexM MCU chips with low sram resources by this feature.

But for Riscv, in riscv-elf.adoc, it seems Tag_RISCV_x3_reg_usage does not support this. How to add this feature for riscv?

I assume that will come with a new code model to doing that, if so, you can allocate a number for Tag_RISCV_x3_reg_usage with a code model proposal.
