The majority of the code doesn't care about the precise value of PyLong_SHIFT, but there are some notable exceptions: - long_pow() requires that PyLong_SHIFT be divisible by 5 - PyLong_{As,From}ByteArray require that PyLong_SHIFT be at least 8 - long_hash() requires that PyLong_SHIFT is *strictly* less than the number of bits in an unsigned long, as do the PyLong <-> long (or unsigned long) conversion functions - the Python int <-> size_t/Py_ssize_t conversion functions expect that PyLong_SHIFT is strictly less than the number of bits in a size_t - the marshal code currently expects that PyLong_SHIFT is a multiple of 15 - NSMALLNEGINTS and NSMALLPOSINTS should be small enough to fit in a single digit; with the current values this forces PyLong_SHIFT >= 9 The values 15 and 30 should fit all of the above requirements, on any platform. */ #if PYLONG_BITS_IN_DIGIT == 30 typedef uint32_t digit; typedef int32_t sdigit; /* signed variant of digit */ typedef uint64_t twodigits; typedef int64_t stwodigits; /* signed variant of twodigits */ #define PyLong_SHIFT 30 #define _PyLong_DECIMAL_SHIFT 9 /* max(e such that 10**e fits in a digit) */ #define _PyLong_DECIMAL_BASE ((digit)1000000000) /* 10 ** DECIMAL_SHIFT */ #elif PYLONG_BITS_IN_DIGIT == 15 typedef unsigned short digit; typedef short sdigit; /* signed variant of digit */ typedef unsigned long twodigits; typedef long stwodigits; /* signed variant of twodigits */ #define PyLong_SHIFT 15 #define _PyLong_DECIMAL_SHIFT 4 /* max(e such that 10**e fits in a digit) */ #define _PyLong_DECIMAL_BASE ((digit)10000) /* 10 ** DECIMAL_SHIFT */ #else #error "PYLONG_BITS_IN_DIGIT should be 15 or 30" #endif #define PyLong_BASE ((digit)1 << PyLong_SHIFT) #define PyLong_MASK ((digit)(PyLong_BASE - 1)) #if PyLong_SHIFT % 5 != 0 #error "longobject.c requires that PyLong_SHIFT be divisible by 5" #endif /* Long integer representation.
