constant that doesn't fit in 32bits in alpha.c

[Jay K]

gcc-4.7.0/gcc/config/alpha/alpha.c


      word1 = expand_and (DImode, word1, GEN_INT (0xffff0fff0000fff0), NULL);


That "big" constant isn't portable since it doesn't fit in 32bits.


1) append LL
or 2) break it up into an expression, like
  ((HOST_WIDE_INT)0xffff0fff) << 8) | 0x0fff0


or such.
#2 is more portable, i.e. to compilers with "__int64" and "0xFFi64" instead of "long long" and "LL".


#3) something involving a double-precision integer using two longs, as I believe gcc does elsewhere.


#2 Depending on HOST_WIDE_INT being portable suffices imho.
