[Alan Modra <amodra at bigpond dot net dot au>]

Make use of the opcode table relocs.

gas/ChangeLog
	From 1999-10-25  Torbjorn Granlund  <tege@swox.com>
	* config/tc-ppc.c (md_apply_fix3): Replace haphazard code for
	determining reloc type with code reading operands->reloc field.

Applying to mainline.
