Transitions between DESC->IE/LE and IE->LE are supported now. 1. For DESC -> LE: pcalau12i $a0,%desc_pc_hi20(var) => lu12i.w $a0,%le_hi20(var) addi.d $a0,$a0,%desc_pc_lo12(var) => ori $a0,$a0,%le_lo12(var) ld.d $a1,$a0,%desc_ld(var) => NOP jirl $ra,$a1,%desc_call(var) => NOP add.d $a0,$a0,$tp 2. For DESC -> IE: pcalau12i $a0,%desc_pc_hi20(var) => pcalau12i $a0,%ie_pc_hi20(var) addi.d $a0,$a0,%desc_pc_lo12(var) => ld.d $a0,$a0,%ie_pc_lo12(var) ld.d $a1,$a0,%desc_ld(var) => NOP jirl $ra,$a1,%desc_call(var) => NOP add.d $a0,$a0,$tp 3. For IE -> LE: pcalau12i $a0,%ie_pc_hi20(var) => lu12i.w $a0,%le_hi20(var) ld.d $a0,$a0,%ie_pc_lo12(var) => ori $a0,$a0,%le_lo12(var) add.d $a0,$a0,$tp 4. When a tls variable is accessed using both DESC and IE, DESC transitions to IE and uses the same GOT entry as IE.
