* config/sparc/linux64.h (CC1_SPEC): Preserve CPU specified by
the user if using the non-default arch size in BI_ARCH configuration.
* config/sparc/sol2-sld-64.h (CC1_SPEC): Ditto.
* config/sparc/sparc.md (cmp_mul_set, cmp_udiv_cc_set):
Fix patterns so that they actually match.
(cmp_sdiv_cc_set): Ditto, also don't require g0 to be zero.
(mulsidi3_sp64, const_mulsidi3_sp64): New patterns.
(const_mulsidi3_sp32): Renamed from const_mulsidi3, only on
TARGET_HARD_MUL32.
(mulsidi3): Reflect this in the expand.
(smulsi3_highpart): Only on TARGET_ARCH32.
(umulsidi3_sp64, const_umulsidi3_sp64): New patterns.
(const_umulsidi3_sp32): Renamed from const_umulsidi3.
(umulsidi3): Reflect this in the expand.
(umulsi3_highpart): Only on TARGET_ARCH32.
(divsi3_sp32): Renamed from divsi3, only on TARGET_ARCH32,
don't require g0 to be zero.
(udivsi3_sp32): Renamed from udivsi3, only on TARGET_ARCH32.
({,u}divsi3): New expands.
({,u}divsi3_sp64): New patterns.
(after lshrdi3_v8plus): Four new patterns to help combiner
optimizing nested mixed mode shifts.
* config/sparc/sparc.c (sparc_override_options): Use deprecated
v8 instructions if optimizing for UltraSPARC I, II, IIi, as it
speed things up. Don't use them by default on plain v9 in 64bit
mode, according to what SPAMv9 sais.
* config/sparc/sparc.h: Fix comments, e.g. Linux already preserves
top 32 bits of %[og][0-7] in signal handlers.
Also, TARGET_HARD_MUL32 now is only true for TARGET_ARCH32.
