  | commit gcc-16-372-g064cac730f8

  |     Improve maybe_hot handling in inliner heuristics
  |     
  |     Inliner currently applies different heuristics to hot and cold calls (the
  |     second are inlined only if the code size will shrink).  It may happen that the
  |     call itself is hot, but the significant time is spent in callee and inlining
  | ... 25 lines of the commit log omitted.
