invoke.texi: Add cpu_type power7.
2008-08-08 Peter Bergner <bergner@vnet.ibm.com>
* doc/invoke.texi: Add cpu_type power7.
* config.in (HAVE_AS_VSX): New.
* config.gcc: Add cpu_type power7.
* configure.ac (HAVE_AS_VSX): Check for assembler support of the
VSX instructions.
* configure: Regenerate.
* config/rs6000/rs6000.c (rs6000_override_options): Alias power7 to
power5.
* config/rs6000/rs6000.h (ASM_CPU_POWER7_SPEC): Define.
(ASM_CPU_SPEC): Pass %(asm_cpu_power7) for -mcpu=power7.
(EXTRA_SPECS): Add asm_cpu_power7 spec string.
