    • cmd/go: ignore errors from go/build for standard packages · 87155d4f 
          
    The go/build package does not know that gccgo's standard packages don't
    have source, and will report an error saying that it can not find them.
    Work around that in the cmd/go sources, since the go/build sources don't
    currently have a list of standard packages.
    
    This should get a real fix in the master sources, somehow.
    
    Fixes golang/go#16701.

    • lra: A multiple_sets is not a simple_move_p (PR73650) · 2008be40 
      In the PR we have a PARALLEL of a move and a compare (a "mr." instruction).
The compare is dead, so single_set on it returns just the move.  Then,
simple_move_p returns true; but the instruction does need reloads in this
case.  This patch solves this by making simple_move_p return false for
every multiple_sets instruction.


	PR rtl-optimization/73650
	* lra-constraints.c (simple_move_p): If the insn is multiple_sets
	it is not a simple move.
