------- Comment #3 from danglin at gcc dot gnu dot org 2007-12-14 17:36 ------- HOST_BITS_PER_WIDE_INT is 32 because NEED_64BIT_HOST_WIDE_INT is not defined in auto-host.h:
/* Define to 1 if HOST_WIDE_INT must be 64 bits wide (see hwint.h). */ #ifndef USED_FOR_TARGET /* #undef NEED_64BIT_HOST_WIDE_INT */ #endif In hwint.h: #if HOST_BITS_PER_LONG >= 64 || !defined NEED_64BIT_HOST_WIDE_INT # define HOST_BITS_PER_WIDE_INT HOST_BITS_PER_LONG # define HOST_WIDE_INT long We have this statement in config.gcc: # need_64bit_hwint Set to yes if HOST_WIDE_INT must be 64 bits wide # for this target. This is true iff this target # supports "long" or "wchar_t" wider than 32 bits. The above is not true, so it would appear this is not a target bug. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34458
