* 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.
