  • LTO supports the newly added GNU make's jobserver that uses named pipes (--jobserver-style=fifo) I believe that's just "GNU make" (instead of "GNU make's"), or maybe "...the newly added jobserver of GNU make...". Not 100% sure myself. > +

  • Might we be able to simplify this to something like "...parallel LTO WPA streaming communicates with it and thus avoids system overcommitting" ? Just two minor points; the patch as such looks fine. Thank you, Gerald
