With -mexplicit-relocs={auto,always} we should still use explicit relocs, but coding all 4 instructions altogether as "pcalau12i.d\t%1,%pc64_hi12(%2)\n\taddi.d\t%0,$r0,%pclo12(%2)\n\tlu32i.d\t%0,%pc64_lo20(%2)\n\tlu52i.d\t%0,%0,%pc64_hi12(%2)" Give me several hours trying to implement this...
You mean to take the last add directive out separately?
