14 | # Notes: |
15 | # | |
16 | # - shared libperl support is tricky. if ever libperl.a ends up | |
17 | # in /usr/local/lib/* it can override any subsequent builds of | |
18 | # that same perl release. to make sure you know where the shared | |
19 | # libperl.a is coming from do a 'dump -Hv perl' and check all the | |
20 | # library search paths in the loader header. | |
21 | # | |
22 | # it would be nice to warn the user if a libperl.a exists that is | |
23 | # going to override the current build, but that would be complex. | |
24 | # | |
25 | # better yet, a solid fix for this situation should be developed. | |

549 | # |
550 | # This deficiency, and others, is apparently a well-documented feature | |
551 | # of AIX 128-bit long doubles: | |
552 | # | |
553 | # http://www-01.ibm.com/support/knowledgecenter/ssw_aix_61/com.ibm.aix.genprogc/128bit_long_double_floating-point_datatype.htm | |

556 | # but searching AIX docs at ibm.com for "128-bit long double | |
557 | # floating-point data type" should surface the latest info. | |
558 | # | |
559 | # Some salient points: | |
560 | # | |
561 | # <quote> | |
562 | # * The 128-bit implementation differs from the IEEE standard for long double | |
563 | # in the following ways: | |
564 | # * Supports only round-to-nearest mode. If the application changes | |
565 | # the rounding mode, results are undefined. | |
566 | # * Does not fully support the IEEE special numbers NaN and INF. | |
567 | # * Does not support IEEE status flags for overflow, underflow, | |
568 | # and other conditions. These flags have no meaning for the 128-bit | |
569 | # long double inplementation. | |
570 | # * The 128-bit long double data type does not support the following math | |
571 | # APIs: atanhl, cbrtl, copysignl, exp2l, expm1l, fdiml, fmal, fmaxl, | |
572 | # fminl, hypotl, ilogbl, llrintl, llroundl, log1pl, log2l, logbl, | |
573 | # lrintl, lroundl, nanl, nearbyintl, nextafterl, nexttoward, | |
574 | # nexttowardf, nexttowardl, remainderl, remquol, rintl, roundl, | |
575 | # scalblnl, scalbnl, tgammal, and truncl. | |
576 | # * The representation of 128-bit long double numbers means that the | |
577 | # following macros required by standard C in the values.h file do not | |
578 | # have clear meaning: | |
579 | # * Number of bits in the mantissa (LDBL_MANT_DIG) | |
580 | # * Epsilon (LBDL_EPSILON) | |
581 | # * Maximum representable finite value (LDBL_MAX) | |
582 | # </quote> | |
