| * Union to access IEEE double memory representation, indexes for double |
| * memory representation, and some macros for double manipulation. |
| * |
| * Also used by packed duk_tval. Use a union for bit manipulation to |
| * minimize aliasing issues in practice. The C99 standard does not |
| * guarantee that this should work, but it's a very widely supported |
| * practice for low level manipulation. |

| * A B C D E F G H |
| * |
| * s sign bit |
| * eee... exponent field |
| * fff... fraction |
| * |
| * See http://en.wikipedia.org/wiki/Double_precision_floating-point_format. |
| * |
| * NaNs are represented as exponent 0x7ff and mantissa != 0. The NaN is a |
| * signaling NaN when the highest bit of the mantissa is zero, and a quiet |
| * NaN when the highest bit is set. |
| * |
| * At least three memory layouts are relevant here: |
| * |
| * A B C D E F G H Big endian (e.g. 68k) DUK_USE_DOUBLE_BE |
| * H G F E D C B A Little endian (e.g. x86) DUK_USE_DOUBLE_LE |
| * D C B A H G F E Mixed/cross endian (e.g. ARM) DUK_USE_DOUBLE_ME |
| * |
| * ARM is a special case: ARM double values are in mixed/cross endian |
| * format while ARM duk_uint64_t values are in standard little endian |
| * format (H G F E D C B A). When a double is read as a duk_uint64_t |
| * from memory, the register will contain the (logical) value |
| * E F G H A B C D. This requires some special handling below. |
| * |
| * Indexes of various types (8-bit, 16-bit, 32-bit) in memory relative to |
| * the logical (big endian) order: |
| * |
| * byte order duk_uint8_t duk_uint16_t duk_uint32_t |
| * BE 01234567 0123 01 |
| * LE 76543210 3210 10 |
| * ME (ARM) 32107654 1032 01 |
| * |
| * Some processors may alter NaN values in a floating point load+store. |
| * For instance, on X86 a FLD + FSTP may convert a signaling NaN to a |
| * quiet one. This is catastrophic when NaN space is used in packed |
| * duk_tval values. See: misc/clang_aliasing.c. |

| * Double NaN manipulation macros related to NaN normalization needed when |
| * using the packed duk_tval representation. NaN normalization is necessary |
| * to keep double values compatible with the duk_tval format. |
| * |
| * When packed duk_tval is used, the NaN space is used to store pointers |
| * and other tagged values in addition to NaNs. Actual NaNs are normalized |
| * to a specific quiet NaN. The macros below are used by the implementation |
| * to check and normalize NaN values when they might be created. The macros |
| * are essentially NOPs when the non-packed duk_tval representation is used. |
| * |
| * A FULL check is exact and checks all bits. A NOTFULL check is used by |
| * the packed duk_tval and works correctly for all NaNs except those that |
| * begin with 0x7ff0. Since the 'normalized NaN' values used with packed |
| * duk_tval begin with 0x7ff8, the partial check is reliable when packed |
| * duk_tval is used. The 0x7ff8 prefix means the normalized NaN will be a |
| * quiet NaN regardless of its remaining lower bits. |
| * |
| * The ME variant below is specifically for ARM byte order, which has the |
| * feature that while doubles have a mixed byte order (32107654), unsigned |
| * long long values has a little endian byte order (76543210). When writing |
| * a logical double value through a ULL pointer, the 32-bit words need to be |
| * swapped; hence the #ifdefs below for ULL writes with DUK_USE_DOUBLE_ME. |
| * This is not full ARM support but suffices for some environments. |
