	*  invoke.texi (-mcpu=740, -mcpu=750): New options.
        (-m(no-)multiple, -m(no-)string): Describe cases for PPC740 &
	PPC750.
1999-01-18  Michael Meissner  <meissner@cygnus.com>
	* rs6000.h ({ASM,CPP}_CPU_SPEC): Add support for all machines
	supported with -mcpu=xxx.
	(processor_type): Add PROCESSOR_PPC750.
	(ADJUST_PRIORITY): Call rs6000_adjust_priority.
	(RTX_COSTS): Supply costs for 750 multiply/divide operations.
	(rs6000_adjust_priority): Add declaration.
	* rs6000.c (rs6000_override_options): -mcpu={750,740} now sets the
	processor type as 750, not 603.  Allow -mmultiple and -mstring on
	little endian 750 systems.
	(rs6000_adjust_priority): Stub for now.
	(get_issue_rate): The PowerPC 750 can issue 2 instructions/cycle.
	* rs6000.md (function/cpu attributes): Add initial ppc750 support.
	* sysv4.h (STRICT_ALIGNMENT): Don't force strict alignment if
	little endian.
	(CC1_SPEC): Pass -mstrict-align if little endian, and not
	overridden.
	(CC1_ENDIAN_{LITTLE,BIG,DEFAULT}_SPEC): Endian specific configs.
	(SUBTARGET_EXTRA_SPECS): Add cc1 endian specs.
	* {sysv4,eabi}le.h (CC1_ENDIAN_DEFAULT_SPEC): Override, default is
	little endian.
	* t-ppcgas (MULTILIB_*): Delete obsolete Solaris multilibs.
