      runtime: convert g.waitreason from string to uint8 · 4eea887f
      Josh Bleecher Snyder authored
      Every time I poke at #14921, the g.waitreason string
      pointer writes show up.
      
      They're not particularly important performance-wise,
      but it'd be nice to clear the noise away.
      
      And it does open up a few extra bytes in the g struct
      for some future use.

      cmd/compile: avoid extra mapaccess in "m[k] op= r" · 73950831
      Vladimir Kuzmin authored
      Currently, order desugars map assignment operations like
      
          m[k] op= r
      
      into
      
          m[k] = m[k] op r
      
      which in turn is transformed during walk into:
      
          tmp := *mapaccess(m, k)
          tmp = tmp op r
          *mapassign(m, k) = tmp
      
      However, this is suboptimal, as we could instead produce just:
      
          *mapassign(m, k) op= r
      
      One complication though is if "r == 0", then "m[k] /= r" and "m[k] %=
      r" will panic, and they need to do so *before* calling mapassign,
      otherwise we may insert a new zero-value element into the map.
      
      It would be spec compliant to just emit the "r != 0" check before
      calling mapassign (see #23735), but currently these checks aren't
      generated until SSA construction. For now, it's simpler to continue
      desugaring /= and %= into two map indexing operations.
      
      Fixes #23661.

      cmd/compile/internal/ssa: emit IMUL3{L/Q} for MUL{L/Q}const on x86 · 85a8d25d
      isharipo authored
      cmd/asm now supports three-operand form of IMUL,
      so instead of using IMUL with resultInArg0, emit IMUL3 instruction.
      
      This results in less redundant MOVs where SSA assigns
      different registers to input[0] and dst arguments.
      
      Note: these have exactly the same encoding when reg0=reg1:
            IMUL3x $const, reg0, reg1
            IMULx $const, reg
      Two-operand IMULx is like a crippled IMUL3x, with dst fixed to input[0].
      This is why we don't bother to generate IMULx for the case where
      dst is the same as input[0].
