Sorry, I mean ".reloc ., R_LARCH_LE_ADD_R, a", not ".reloc 0".
And if you must go with an additional operand of add.d you should make
sure things like "add.d $t0, $t0, $t1, 114" or "add.d $t0, $t0, $t1,
%lo12(x)" rejected with a reasonable message (not an internal error, nor
an abort, nor silently producing broken binary).
