      cmd/8g: eliminate obviously useless temps before regopt. · fa316ba4
      Rémy Oudompheng authored
      This patch introduces a sort of pre-regopt peephole optimization.
      When a temporary is introduced that just holds a value for the
      duration of the next instruction and is otherwise unused, we
      elide it to make the job of regopt easier.
      
      Since x86 has very few registers, this situation happens very
      often. The result is large savings in stack variables for
      arithmetic-heavy functions.

      net: protocol specific listen functions return a proper local socket address · 677c6e6e
      Mikio Hara authored
      When a nil listener address is passed to some protocol specific
      listen function, it will create an unnamed, unbound socket because
      of the nil listener address. Other listener functions may return
      invalid address error.
      
      This CL allows to pass a nil listener address to all protocol
      specific listen functions to fix above inconsistency. Also make it
      possible to return a proper local socket address in case of a nil
      listner address.
      
      Fixes #4190.
      Fixes #3847.

      net: make LocalAddr on multicast UDPConn return a listening address · 0ae80785
      Mikio Hara authored
      The package go.net/ipv4 allows to exist a single UDP listener
      that join multiple different group addresses. That means that
      LocalAddr on multicast UDPConn returns a first joined group
      address is not desirable.
