Ok, successfully bootstrapped a freshly checked out and patched
egcs_1_1_branch. Must have been either the mask_operand stuff or your patch
to rs6000.md that fixed it.

Here's the ChangeLog entry missing before.

Fri Jul 17 1998  Richard Henderson  <rth@cygnus.com>
		  Franz Sirl <Franz.Sirl-kernel@lauterbach.com>

	* rs6000/rs6000.c: Add support for CONSTANT_P_RTX
	* rs6000/rs6000.md: Likewise.
	* rs6000/rs6000.h: Update PREDICATE_CODES accordingly


Franz.
