Hmm, and it looks like we should use (reg:P 4) instead of match_operand
here, because the instruction does not work for a different register:

Add support for TLS descriptors on normal code model and extreme code model.
Normal code model instruction sequence:
-mno-explicit-relocs:
la.tls.desc $r4, s
add.d $r12, $r4, $r2
-mexplicit-relocs:
pcalau12i $r4,%desc_pc_hi20(s)
addi.d $r4,$r4,%desc_pc_lo12(s)
