There seems no real reason to require -mexplicit-relocs=always for
-mcmodel=extreme or model attribute. As the linker does not know how to
relax a 3-operand la.local or la.global pseudo instruction, just emit
explicit relocs for SYMBOL_PCREL64, and under TARGET_CMODEL_EXTREME also
SYMBOL_GOT_DISP.
I think there is no problem, HeJinyang is testing and if there is no
problem with the
test play, you can merge in.
Thanks!
Thanks! Now I can compile linux kernel with `-mexplicit-relocs=auto`,
and instructions is as expected. (kernel relax some pcalau12i+addi.d
pair to pcaddi and module still access percpu var by 64bits-la.pcrel)
