|
|
1195 * |
|
|
1196 * NaNs are represented as exponent 0x7ff and mantissa != 0. The NaN is a |
|
|
1197 * signaling NaN when the highest bit of the mantissa is zero, and a quiet |
|
|
1198 * NaN when the highest bit is set. |
|
|
1199 * |
|
|
1200 * At least three memory layouts are relevant here: |
|
|
1201 * |
|
|
1202 * A B C D E F G H Big endian (e.g. 68k) DUK_USE_DOUBLE_BE |
|
|
1203 * H G F E D C B A Little endian (e.g. x86) DUK_USE_DOUBLE_LE |
|
|
1204 * D C B A H G F E Mixed/cross endian (e.g. ARM) DUK_USE_DOUBLE_ME |
|
|
1205 * |
|
|
1206 * ARM is a special case: ARM double values are in mixed/cross endian |
|
|
1207 * format while ARM duk_uint64_t values are in standard little endian |
|
|
1208 * format (H G F E D C B A). When a double is read as a duk_uint64_t |
|
|
1209 * from memory, the register will contain the (logical) value |
|
|
1210 * E F G H A B C D. This requires some special handling below. |
|
|
1211 * |
|
|
1212 * Indexes of various types (8-bit, 16-bit, 32-bit) in memory relative to |
|
|
1213 * the logical (big endian) order: |
|
|
1214 * |
|
|
1215 * byte order duk_uint8_t duk_uint16_t duk_uint32_t |
|
|
1216 * BE 01234567 0123 01 |
|
|
1217 * LE 76543210 3210 10 |
|
|
1218 * ME (ARM) 32107654 1032 01 |
|
|
1219 * |
|
|
1220 * Some processors may alter NaN values in a floating point load+store. |
|
|
1221 * For instance, on X86 a FLD + FSTP may convert a signaling NaN to a |
|
|
1222 * quiet one. This is catastrophic when NaN space is used in packed |
|
|
1223 * duk_tval values. See: misc/clang_aliasing.c. |

1376 * using the packed duk_tval representation. NaN normalization is necessary |
|
|
1377 * to keep double values compatible with the duk_tval format. |
|
|
1378 * |
|
|
1379 * When packed duk_tval is used, the NaN space is used to store pointers |
|
|
1380 * and other tagged values in addition to NaNs. Actual NaNs are normalized |
|
|
1381 * to a specific quiet NaN. The macros below are used by the implementation |
|
|
1382 * to check and normalize NaN values when they might be created. The macros |
|
|
1383 * are essentially NOPs when the non-packed duk_tval representation is used. |
|
|
1384 * |
|
|
1385 * A FULL check is exact and checks all bits. A NOTFULL check is used by |
|
|
1386 * the packed duk_tval and works correctly for all NaNs except those that |
|
|
1387 * begin with 0x7ff0. Since the 'normalized NaN' values used with packed |
|
|
1388 * duk_tval begin with 0x7ff8, the partial check is reliable when packed |
|
|
1389 * duk_tval is used. The 0x7ff8 prefix means the normalized NaN will be a |
|
|
1390 * quiet NaN regardless of its remaining lower bits. |
|
|
1391 * |
|
|
1392 * The ME variant below is specifically for ARM byte order, which has the |
|
|
1393 * feature that while doubles have a mixed byte order (32107654), unsigned |
|
|
1394 * long long values has a little endian byte order (76543210). When writing |
|
|
1395 * a logical double value through a ULL pointer, the 32-bit words need to be |
|
|
1396 * swapped; hence the #ifdefs below for ULL writes with DUK_USE_DOUBLE_ME. |
|
|
1397 * This is not full ARM support but suffices for some environments. |
