/* Processor dependencies */


/* Define ARCH_SIXTYFOUR if the processor has a natural word size of 64 bits.
   That is, sizeof(char *) = 8.
   Otherwise, leave ARCH_SIXTYFOUR undefined.
   This assumes sizeof(char *) = 4. */


/* Define ARCH_BIG_ENDIAN if the processor is big endian (the most
   significant byte of an integer stored in memory comes first).
   Leave ARCH_BIG_ENDIAN undefined if the processor is little-endian
   (the least significant byte comes first).


/* Define ARCH_ALIGN_DOUBLE if the processor requires doubles to be
   doubleword-aligned. Leave ARCH_ALIGN_DOUBLE undefined if the processor
   supports word-aligned doubles. */

#undef ARCH_CODE32

/* Define ARCH_CODE32 if, on a 64-bit machine, code pointers fit in 32 bits,
   i.e. the code segment resides in the low 4G of the addressing space.
   ARCH_CODE32 is ignored on 32-bit machines. */

   respectively. */

#define ARCH_INT64_TYPE long long
#define ARCH_UINT64_TYPE unsigned long long

/* Define ARCH_INT64_TYPE and ARCH_UINT64_TYPE to 64-bit integer types,
   typically "long long" and "unsigned long long" on 32-bit platforms,
   and "long" and "unsigned long" on 64-bit platforms.
   If the C compiler doesn't support any 64-bit integer type,
   leave both ARCH_INT64_TYPE and ARCH_UINT64_TYPE undefined. */


/* Define ARCH_INT64_PRINTF_FORMAT to the printf format used for formatting
   values of type ARCH_INT64_TYPE.  This is usually "ll" on 32-bit
   platforms and "l" on 64-bit platforms.
   Leave undefined if ARCH_INT64_TYPE is undefined.  */

#define ARCH_ALIGN_INT64

/* Define ARCH_ALIGN_INT64 if the processor requires 64-bit integers to be
   doubleword-aligned. Leave ARCH_ALIGN_INT64 undefined if the processor
   supports word-aligned 64-bit integers.  Leave undefined if
   64-bit integers are not supported. */


/* Leave NONSTANDARD_DIV_MOD undefined if the C operators / and % implement
   round-towards-zero semantics, as specified by ISO C 9x and implemented
   by most contemporary processors.  Otherwise, or if you don't know,
   define NONSTANDARD_DIV_MOD: this will select a slower but correct
   software emulation of division and modulus. */
