2293 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
2294 invisible reference in registers, but then spilled to the stack.
2295 Remove code to emit a second stab for such parameters; it attempts
2296 to describe the value's location by introducing a synthetic C++
2297 `reference' type, and then saying the stack slot has that
2298 reference type. This loses type information (breaking GDB's
2299 `ptype' command, among other things) just to describe a location
2300 which stabs can represent correctly in other ways.

2344 * extend.texi: Document builtin imaxabs.
2346 2000-12-01 Joseph S. Myers <jsm28@cam.ac.uk>
2348 * c-common.c: Include "defaults.h".
