Fix ldbl-128ibm strtold overflow handling (bug 14551). For ldbl-128ibm, if the result of strtold overflows in the final conversion from MPN to IBM long double (because the exponent for a 106-bit IEEE result is 1023 but the high part would end up as 0x1p1024, which overflows), that conversion code fails to handle this and produces an invalid long double value (high part infinite, low part not zero) without raising exceptions or setting errno. This patch adds an explicit check for this case to ensure an appropriate result is returned in a way that ensures the right exceptions are raised, with errno set. Tested for powerpc. [BZ #14551] * sysdeps/ieee754/ldbl-128ibm/mpn2ldbl.c: Include <errno.h>. (__mpn_construct_long_double): If high part overflows to infinity, set errno and recompute overflowed result of the correct sign. * sysdeps/ieee754/ldbl-128ibm/Makefile [$(subdir) = stdlib] (tests): Add tst-strtold-ldbl-128ibm.

Fix ldbl-128ibm fmodl handling of equal arguments with low part zero (bug 19602). The ldbl-128ibm implementation of fmodl has logic to detect when the first argument has absolute value less than or equal to the second. This logic is only correct for nonzero low parts; if the high parts are equal and the low parts are zero, then the signs of the low parts (which have no semantic effect on the value of the long double number) can result in equal values being wrongly treated as unequal, and an incorrect result being returned from fmodl. This patch fixes this by checking for the case of zero low parts. Although this does show up in tests from libm-test.inc (both tests of fmodl, and, indirectly, of remainderl / dreml), the dependence on non-semantic zero low parts means that test shouldn't be expected to reproduce it reliably; thus, this patch adds a standalone test that sets up affected values using unions. Tested for powerpc. [BZ #19602] * sysdeps/ieee754/ldbl-128ibm/e_fmodl.c (__ieee754_fmodl): Handle equal high parts and both low parts zero specially. * sysdeps/ieee754/ldbl-128ibm/test-fmodl-ldbl-128ibm.c: New test. * sysdeps/ieee754/ldbl-128ibm/Makefile [$(subdir) = math] (tests): Add test-fmodl-ldbl-128ibm.

Fix ldbl-128ibm remainderl equality test for zero low part (bug 19677). The ldbl-128ibm implementation of remainderl has logic resulting in incorrect tests for equality of the absolute values of the arguments in the case of zero low parts. If the low parts are both zero but with different signs, this can wrongly cause equal arguments to be treated as different, resulting in turn in incorrect signs of zero result in nondefault rounding modes arising from the subtractions done when the arguments are not equal. This patch fixes the logic to convert -0 low parts into +0 before the comparison (remquo already has separate logic to deal with signs of zero results, so doesn't need such a change). Tests are added for remainderl and remquol similar to that for fmodl, and based on a refactoring of it, since the bug depends on low parts which should not be relied upon in tests not setting the representation explicitly (although in fact the bug shows up in test-ldouble with current GCC). Tested for powerpc. [BZ #19677] * sysdeps/ieee754/ldbl-128ibm/e_remainderl.c (__ieee754_remainderl): Put zero low parts in canonical form. * sysdeps/ieee754/ldbl-128ibm/test-fmodrem-ldbl-128ibm.c: New file.

Add canonicalize, canonicalizef, canonicalizel. TS 18661-1 defines canonicalize functions to produce a canonical version of a floating-point representation. This patch implements these functions for glibc. As with the iscanonical macro, these functions are oriented to the decimal floating-point case, where some values have both canonical and noncanonical representations. However, the functions have a return value that says whether they succeeded in storing a canonical result; thus, they can fail for the case of an invalid representation (while still not making any particular choice from among multiple equally canonical valid representations of the same value). Since no floating-point formats in glibc actually have noncanonical valid representations, a type-generic implementation of these functions can be used that expects iscanonical to return 0 only for invalid representations. Now that iscanonical is used within libm.so, libm_hidden_proto / libm_hidden_def are added for __iscanonicall. The definition of these functions is intended to correspond to a convertFormat operation to the same floating-point format. Thus, they convert signaling NaNs to quiet NaNs, raising the "invalid" exception. Such a conversion "should" produce "the canonical version of that signaling NaN made quiet". libm-test.inc is made to check NaN payloads for the output of these functions, a new feature (at some point manipulation functions such as fabs and copysign should have tests added that verify payload preservation for them). As however some architectures may not follow the recommended practice of preserving NaN payloads when converting a signaling NaN to quiet, a new math-tests.h macro SNAN_TESTS_PRESERVE_PAYLOAD is added, and defined to 0 for non-NAN2008 MIPS; any other architectures seeing test failures for lack of payload preservation in this case should also define this macro to 0. (If any cases arise where the sign isn't preserved either, those should have a similar macro added.) The ldbl-96 and ldbl-128ibm tests of iscanonical are renamed and adapted to test canonicalizel as well on the same representations.

Add totalorder, totalorderf, totalorderl. TS 18661-1 defines totalorder functions implementing the totalOrder comparison operation from IEEE 754-2008. This patch implements these functions for glibc, including the type-generic macro in <tgmath.h>. (The totalordermag functions will be added in a separate patch.) The description of the totalOrder operation is complicated. However, for IEEE interchange binary formats and the preferred quiet NaN convention, what that complicated description means is that you interpret the representation as a sign-magnitude integer (with -0 coming before +0) and do a <= comparison on that interpretation. For finite values and infinities the ordering of the sign-magnitude integers is just the same as the ordering of floating-point values, so this extends that to all representations. (Different representations of the same floating-point value - which includes same quantum in the decimal case - must still be considered equal by this operation, but that issue doesn't arise for IEEE interchange binary formats.) So the complications are: * When MIPS quiet NaN conventions are in use, the representation of NaNs needs adjusting before making such an integer comparison. This patch does this adjustment only when both arguments are NaNs, as there's no need for it if only one is a NaN, and as long as both are NaNs you can just flip the relevant bits without any problems from this turning a NaN into an infinity. * For the m68k version of ldbl-96, where the high mantissa bit is "don't care" for infinities and NaNs, representations where it differs must compare the same. Note: although the testcase for this compiles, I have not actually tested on m68k. * For ldbl-128ibm, the low part must be ignored when the high part is NaN, and low parts of +0 and -0 must be considered the same whatever the high part. The new tests in libm-test.inc are the first tests there specifying particular payloads for input NaNs. Separate tests are also added for the ldbl-96 and ldbl-128ibm special cases where there are different representations of the same value that must compare equal (which can't be covered in libm-test.inc as that only specifies values, not representations).

test-totalorderl-ldbl-128ibm
Fix ldbl-128ibm fmodl handling of equal arguments with low part zero (bug 19602). The ldbl-128ibm implementation of fmodl has logic to detect when the first argument has absolute value less than or equal to the second. This logic is only correct for nonzero low parts; if the high parts are equal and the low parts are zero, then the signs of the low parts (which have no semantic effect on the value of the long double number) can result in equal values being wrongly treated as unequal, and an incorrect result being returned from fmodl. This patch fixes this by checking for the case of zero low parts. Although this does show up in tests from libm-test.inc (both tests of fmodl, and, indirectly, of remainderl / dreml), the dependence on non-semantic zero low parts means that test shouldn't be expected to reproduce it reliably; thus, this patch adds a standalone test that sets up affected values using unions. Tested for powerpc. [BZ #19602] * sysdeps/ieee754/ldbl-128ibm/e_fmodl.c (__ieee754_fmodl): Handle equal high parts and both low parts zero specially. * sysdeps/ieee754/ldbl-128ibm/test-fmodl-ldbl-128ibm.c: New test. * sysdeps/ieee754/ldbl-128ibm/Makefile [$(subdir) = math] (tests): Add test-fmodl-ldbl-128ibm.
