   155  // __CONCAT's, all the __CONCAT's must be at the left.  __CONCAT can also
   156  // concatenate double-quoted strings produced by the __STRING macro, but
   157  // this only works with ANSI C.

   174  // syntax.  Therefore implement something similar under the name
   175  // __generic().  Unlike _Generic(), this macro can only distinguish

   197  // sees a more linear flow, thus improving cache behavior, etc.
   198  //
   199  // The following two macros provide us with a way to utilize this
   200  // compiler feature.  Use __predict_true() if you expect the expression
   201  // to evaluate to true, and __predict_false() if you expect the
   202  // expression to evaluate to false.
   203  //
   204  // A few notes about usage:
   205  //
   206  //	* Generally, __predict_false() error condition checks (unless
   207  //	  you have some _strong_ reason to do otherwise, in which case
   208  //	  document it), and/or __predict_true() `no-error' condition
   209  //	  checks, assuming you want to optimize for the no-error case.
   210  //
   211  //	* Other than that, if you don't know the likelihood of a test
   212  //	  succeeding from empirical or other `hard' evidence, don't
   213  //	  make predictions.
   214  //
   215  //	* These are meant to be used in places that are run `a lot'.
   216  //	  It is wasteful to make predictions in code that is run
   217  //	  seldomly (e.g. at subsystem initialization time) as the
   218  //	  basic block reordering that this affects can often generate
   219  //	  larger code.
   220  
   221  // We define this here since <stddef.h>, <sys/queue.h>, and <sys/types.h>

   224  // Given the pointer x to the member m of the struct s, return
