    • libgo: separate mksysinfo inputs into separate Makefile targets · 14cda8a1 
          
    This is a step toward a version of mksysinfo that generates information
    for the runtime package.  This will be used to generate the
    runtime_sysinfo.go file, which is currently directly generated by a
    Makefile target.

    • compiler: avoid call duplication during order eval. · c7ff1374 
          
    During the compiler's order_evaluations() pass, duplicate
    call statements were being created and inserted into block
    statement lists in situations where there were calls returning
    multiple arguments. These duplicates were benign in that they
    were ignored during backend code generation, however they
    did cause duplicate calls in AST dumps. Tweak the order
    evaluation code to handle this case better and avoid inserting
    these duplicates.
    
    Fixes golang/go#17237

    • compiler: add src information to AST dumps (part 1 of 2). · 437018ea 
          
    When emitting AST dumps, tag the end of selected statements with with
    source file and line number information where available. Example:
    
      tmp.76832448 = 0 // p.go:6
    
    Requires a corresponding change in gcc/go as well as this change to
    gofrontend.
