| 1205 * Also used by packed duk_tval. Use a union for bit manipulation to | |
| 1206 * minimize aliasing issues in practice. The C99 standard does not | |
| 1207 * guarantee that this should work, but it's a very widely supported | |
| 1208 * practice for low level manipulation. | |

| 1217 * fff... fraction | |
| 1218 * | |
| 1219 * See http://en.wikipedia.org/wiki/Double_precision_floating-point_format. | |
| 1220 * | |
| 1221 * NaNs are represented as exponent 0x7ff and mantissa != 0. The NaN is a | |
| 1222 * signaling NaN when the highest bit of the mantissa is zero, and a quiet | |
| 1223 * NaN when the highest bit is set. | |
| 1224 * | |
| 1225 * At least three memory layouts are relevant here: | |
| 1226 * | |
| 1227 * A B C D E F G H Big endian (e.g. 68k) DUK_USE_DOUBLE_BE | |
| 1228 * H G F E D C B A Little endian (e.g. x86) DUK_USE_DOUBLE_LE | |
| 1229 * D C B A H G F E Mixed/cross endian (e.g. ARM) DUK_USE_DOUBLE_ME | |
| 1230 * | |
| 1231 * ARM is a special case: ARM double values are in mixed/cross endian | |
| 1232 * format while ARM duk_uint64_t values are in standard little endian | |
| 1233 * format (H G F E D C B A). When a double is read as a duk_uint64_t | |
| 1234 * from memory, the register will contain the (logical) value | |
| 1235 * E F G H A B C D. This requires some special handling below. | |
| 1236 * | |
| 1237 * Indexes of various types (8-bit, 16-bit, 32-bit) in memory relative to | |
| 1238 * the logical (big endian) order: | |
| 1239 * | |
| 1240 * byte order duk_uint8_t duk_uint16_t duk_uint32_t | |
| 1241 * BE 01234567 0123 01 | |
| 1242 * LE 76543210 3210 10 | |
| 1243 * ME (ARM) 32107654 1032 01 | |
| 1244 * | |
| 1245 * Some processors may alter NaN values in a floating point load+store. | |
| 1246 * For instance, on X86 a FLD + FSTP may convert a signaling NaN to a | |
| 1247 * quiet one. This is catastrophic when NaN space is used in packed | |
| 1248 * duk_tval values. See: misc/clang_aliasing.c. | |

| 1400 * Double NaN manipulation macros related to NaN normalization needed when | |
| 1401 * using the packed duk_tval representation. NaN normalization is necessary | |
| 1402 * to keep double values compatible with the duk_tval format. | |
| 1403 * | |
| 1404 * When packed duk_tval is used, the NaN space is used to store pointers | |
| 1405 * and other tagged values in addition to NaNs. Actual NaNs are normalized | |
| 1406 * to a specific quiet NaN. The macros below are used by the implementation | |
| 1407 * to check and normalize NaN values when they might be created. The macros | |
| 1408 * are essentially NOPs when the non-packed duk_tval representation is used. | |
| 1409 * | |
| 1410 * A FULL check is exact and checks all bits. A NOTFULL check is used by | |
| 1411 * the packed duk_tval and works correctly for all NaNs except those that | |
| 1412 * begin with 0x7ff0. Since the 'normalized NaN' values used with packed | |
| 1413 * duk_tval begin with 0x7ff8, the partial check is reliable when packed | |
| 1414 * duk_tval is used. The 0x7ff8 prefix means the normalized NaN will be a | |
| 1415 * quiet NaN regardless of its remaining lower bits. | |
| 1416 * | |
| 1417 * The ME variant below is specifically for ARM byte order, which has the | |
| 1418 * feature that while doubles have a mixed byte order (32107654), unsigned | |
| 1419 * long long values has a little endian byte order (76543210). When writing | |
| 1420 * a logical double value through a ULL pointer, the 32-bit words need to be | |
| 1421 * swapped; hence the #ifdefs below for ULL writes with DUK_USE_DOUBLE_ME. | |
| 1422 * This is not full ARM support but suffices for some environments. | |
