| 1257 * NaNs are represented as exponent 0x7ff and mantissa != 0. The NaN is a | |
| 1258 * signaling NaN when the highest bit of the mantissa is zero, and a quiet | |
| 1259 * NaN when the highest bit is set. | |
| 1260 * | |
| 1261 * At least three memory layouts are relevant here: | |
| 1262 * | |
| 1263 * A B C D E F G H Big endian (e.g. 68k) DUK_USE_DOUBLE_BE | |
| 1264 * H G F E D C B A Little endian (e.g. x86) DUK_USE_DOUBLE_LE | |
| 1265 * D C B A H G F E Mixed/cross endian (e.g. ARM) DUK_USE_DOUBLE_ME | |
| 1266 * | |
| 1267 * ARM is a special case: ARM double values are in mixed/cross endian | |
| 1268 * format while ARM duk_uint64_t values are in standard little endian | |
| 1269 * format (H G F E D C B A). When a double is read as a duk_uint64_t | |
| 1270 * from memory, the register will contain the (logical) value | |
| 1271 * E F G H A B C D. This requires some special handling below. | |
| 1272 * | |
| 1273 * Indexes of various types (8-bit, 16-bit, 32-bit) in memory relative to | |
| 1274 * the logical (big endian) order: | |
| 1275 * | |
| 1276 * byte order duk_uint8_t duk_uint16_t duk_uint32_t | |
| 1277 * BE 01234567 0123 01 | |
| 1278 * LE 76543210 3210 10 | |
| 1279 * ME (ARM) 32107654 1032 01 | |
| 1280 * | |
| 1281 * Some processors may alter NaN values in a floating point load+store. | |
| 1282 * For instance, on X86 a FLD + FSTP may convert a signaling NaN to a | |
| 1283 * quiet one. This is catastrophic when NaN space is used in packed | |
| 1284 * duk_tval values. See: misc/clang_aliasing.c. | |

| 1436 * Double NaN manipulation macros related to NaN normalization needed when | |

| 1438 * to keep double values compatible with the duk_tval format. | |
| 1439 * | |
| 1440 * When packed duk_tval is used, the NaN space is used to store pointers | |
| 1441 * and other tagged values in addition to NaNs. Actual NaNs are normalized | |
| 1442 * to a specific quiet NaN. The macros below are used by the implementation | |
| 1443 * to check and normalize NaN values when they might be created. The macros | |
| 1444 * are essentially NOPs when the non-packed duk_tval representation is used. | |
| 1445 * | |
| 1446 * A FULL check is exact and checks all bits. A NOTFULL check is used by | |
| 1447 * the packed duk_tval and works correctly for all NaNs except those that | |
| 1448 * begin with 0x7ff0. Since the 'normalized NaN' values used with packed | |
| 1449 * duk_tval begin with 0x7ff8, the partial check is reliable when packed | |
| 1450 * duk_tval is used. The 0x7ff8 prefix means the normalized NaN will be a | |
| 1451 * quiet NaN regardless of its remaining lower bits. | |
| 1452 * | |
| 1453 * The ME variant below is specifically for ARM byte order, which has the | |
| 1454 * feature that while doubles have a mixed byte order (32107654), unsigned | |
| 1455 * long long values has a little endian byte order (76543210). When writing | |
