    • syscall: RawSockaddr fix for ppc64, ppc64le · 1ca95ba0 
          
    The struct RawSockaddr contains a field Data which
    should be uint8 on ppc64 and ppc64le, but is declared
    as int8 in gccgo.  This change adds a two new files
    which contain the structure declaration for
    RawSockaddr, one with the correct types for for ppc64
    and ppc64le, and the other for non-ppc64 platforms.
    
    Fixes golang/go#11469

    • libgo/testsuite: kill sleep process in gotest · ca81dee3 
          
    This change modifies the "gotest" shell script
    to kill all processes, including "sleep", spawned
    by the timeout subshell. This prevents the sleep
    process from living beyond the gotest process.
    
    BACKGROUND
    
    The "gotest" shell script spawns "sleep" processes
    in the background to kill off test cases that run
    past their specified timeout. There are commands
    included that appear to kill the sleep process,
    but they only kill the parent shell, causing the
    sleep process to reparent.
    
    The orphaned sleep process can cause issues when
    gotest is run under some build systems, such as
    Ninja [0]. The particular issue with Ninja is the
    method it uses to identify terminated processes:
    it creates a pipe, passes the write end to the
    child process, and waits for EOF. In the case of
    libgo/gotest, the orphaned sleep process inherits
    the pipe FD and keeps it open for 4 minutes by
    default.

    runtime: Remove call to __builtin_frame_address.
    
    __builtin_frame_address was only supposed to use nonzero arguments
    for debugging purposes.  Calling it with nonzero arguments can have
    unpredictable results and uses are now marked unsafe when
    -Wframe-address is enabled.
