/*  Relax tls le, mainly relax the process of getting TLS le symbolic addresses.
  there are three situations in which an assembly instruction sequence needs to
  be relaxed:
  symbol address = tp + offset (symbol),offset (symbol) = le_hi20_r + le_lo12_r

  Case 1:
  in this case, the rd register in the st.{w/d} instruction does not store the
  full tls symbolic address, but tp + le_hi20_r, which is a part of the tls
  symbolic address, and then obtains the rd + le_lo12_r address through the
  st.w instruction feature.
  this is the full tls symbolic address (tp + le_hi20_r + le_lo12_r).

  before relax:				after relax:

  lu12i.w   $rd,%le_hi20_r (sym)	==> (instruction deleted)
  add.{w/d} $rd,$rd,$tp,%le_add_r (sym) ==> (instruction deleted)
  st.{w/d}  $rs,$rd,%le_lo12_r (sym)    ==> st.{w/d}   $rs,$tp,%le_lo12_r (sym)

  Case 2:
  in this case, ld.{w/d} is similar to st.{w/d} in case1.

  before relax:				after relax:

  lu12i.w   $rd,%le_hi20_r (sym)	==> (instruction deleted)
  add.{w/d} $rd,$rd,$tp,%le_add_r (sym) ==> (instruction deleted)
  ld.{w/d}  $rs,$rd,%le_lo12_r (sym)    ==> ld.{w/d}   $rs,$tp,%le_lo12_r (sym)

  Case 3:
  in this case,the rs register in addi.{w/d} stores the full address of the tls
  symbol (tp + le_hi20_r + le_lo12_r).

  before relax:				after relax:

  lu12i.w    $rd,%le_hi20_r (sym)	 ==> (instruction deleted)
  add.{w/d}  $rd,$rd,$tp,%le_add_r (sym) ==> (instruction deleted)
  addi.{w/d} $rs,$rd,%le_lo12_r (sym)    ==> addi.{w/d} $rs,$tp,%le_lo12_r (sym)


  For relocation of all old LE instruction sequences, whether it is
  a normal code model or an extreme code model, relaxation will be
  performed when the relaxation conditions are met.

  nomal code model:
  lu12i.w   $rd,%le_hi20(sym)	    => (deleted)
  ori	    $rd,$rd,le_lo12(sym)    => ori  $rd,$zero,le_lo12(sym)

  ori	    $rd,$rd,%le_lo12(sym)   => ori  $rd,$zero,le_lo12(sym)
