2799 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
2800 invisible reference in registers, but then spilled to the stack.
2801 Remove code to emit a second stab for such parameters; it attempts
2802 to describe the value's location by introducing a synthetic C++
2803 `reference' type, and then saying the stack slot has that
2804 reference type. This loses type information (breaking GDB's
2805 `ptype' command, among other things) just to describe a location
2806 which stabs can represent correctly in other ways.

2850 * extend.texi: Document builtin imaxabs.
2852 2000-12-01 Joseph S. Myers <jsm28@cam.ac.uk>
2854 * c-common.c: Include "defaults.h".
