Gabriel F. T. Gomes	8466ee1cb7	float128: Add signbit alternative for old compilers In math/math.h, __MATH_TG will expand signbit to __builtin_signbit, e.g.: __builtin_signbitf128, before GCC 6. However, there has never been a __builtin_signbitf128 in GCC and the type-generic builtin is only available since GCC 6. For older GCC, this patch defines __builtin_signbitf128 to __signbitf128, so that the internal function is used instead of the non-existent builtin. This patch also changes the implementation of __signbitf128, because it was reusing the implementation of __signbitl from ldbl-128, which calls __builtin_signbitl. Using the long double version of the builtin is not correct on machines where _Float128 is ABI-distinct from long double (i.e.: ia64, powerpc64le, x86, x86_84). The new implementation does not rely on builtins when being built with GCC versions older than 6.0. The new code does not currently affect powerpc64le builds, because only GCC 6.2 fulfills the requirements from configure. It might affect powerpc64le builds if those requirements are backported to older versions of the compiler. The new code affects x86_64 builds, since glibc is supposed to build correctly with older versions of GCC. Tested for powerpc64le and x86_64. include/math.h (__signbitf128): Define as hidden. * sysdeps/ieee754/float128/s_signbitf128.c (__signbitf128): Reimplement without builtins. * sysdeps/ia64/bits/floatn.h [!__GNUC_PREREQ (6, 0)] (__builtin_signbitf128): Define to __signbitf128. * sysdeps/powerpc/bits/floatn.h: Likewise. * sysdeps/x86/bits/floatn.h: Likewise.	9 years ago
Gabriel F. T. Gomes	7fa1d9462b	Add libio-mtsafe flags to the build of strfromf128 Similar to the other functions in the strfrom class, strfromf128 calls __printf_fp in order to convert the floating-point value to characters. This requires the value of IO_MTSAFE_IO. Tested for powerpc64le and s390x. * sysdeps/ieee754/float128/Makefile (CFLAGS-strfromf128.c): Add $(libio-mtsafe) to get the value of IO_MTSAFE_IO.	9 years ago
Joseph Myers	f20079d219	Fix float128_private.h redefinition of SET_RESTORE_ROUNDL. As with other long double identifiers, float128_private.h has a redefinition of SET_RESTORE_ROUNDL. However, that redefinition is broken, since this is a macro with one argument being defined to take no arguments. This patch fixes the redefinition. (x86_64 needs the redefinition because SET_RESTORE_ROUNDL only changes the x87 rounding mode, whereas _Float128 arithmetic uses the SSE rounding mode instead on x86_64.) Tested for x86_64 (in conjunction with float128 patches). * sysdeps/ieee754/float128/float128_private.h [SET_RESTORE_ROUNDF128] (SET_RESTORE_ROUNDL): Take an argument and pass it to SET_RESTORE_ROUNDF128.	9 years ago
Joseph Myers	db7a548d02	Make float128_private.h work with generic ieee754.h. float128_private.h redefines ieee754.h identifiers ieee854_long_double and IEEE854_LONG_DOUBLE_BIAS to map them to identifiers from ieee754_float128.h. This causes problems when ieee754.h is included after float128_private.h and it's a version of ieee754.h that also defines those identifiers; specifically, sysdeps/ieee754/ieee754.h, which defines those identifiers for the x86 extended format. This patch fixes this by ensuring an include of ieee754.h from float128_private.h before the redefinitions. Tested for x86_64 (in conjunction with float128 patches). * sysdeps/ieee754/float128/float128_private.h: Include <ieee754.h>.	9 years ago
Joseph Myers	33711da4e9	Fix float128 uses of xlocale.h. Three float128 files still include xlocale.h after it was removed. I don't know why this didn't cause problems for powerpc64le float128 testing; it did cause problems for my x86_64 float128 testing. This patch changes the includes to use bits/types/locale_t.h. Tested for x86_64 (in conjunction with float128 patches). * sysdeps/ieee754/float128/strtof128_l.c: Include <bits/types/locale_t.h> instead of <xlocale.h>. * sysdeps/ieee754/float128/wcstof128.c: Likewise. * sysdeps/ieee754/float128/wcstof128_l.c: Likewise.	9 years ago
Zack Weinberg	af85385f31	Use locale_t, not __locale_t, throughout glibc <locale.h> is specified to define locale_t in POSIX.1-2008, and so are all of the headers that define functions that take locale_t arguments. Under _GNU_SOURCE, the additional headers that define such functions have also always defined locale_t. Therefore, there is no need to use __locale_t in public function prototypes, nor in any internal code. * ctype/ctype-c99_l.c, ctype/ctype.h, ctype/ctype_l.c * include/monetary.h, include/stdlib.h, include/time.h * include/wchar.h, locale/duplocale.c, locale/freelocale.c * locale/global-locale.c, locale/langinfo.h, locale/locale.h * locale/localeinfo.h, locale/newlocale.c * locale/nl_langinfo_l.c, locale/uselocale.c * localedata/bug-usesetlocale.c, localedata/tst-xlocale2.c * stdio-common/vfscanf.c, stdlib/monetary.h, stdlib/stdlib.h * stdlib/strfmon_l.c, stdlib/strtod_l.c, stdlib/strtof_l.c * stdlib/strtol.c, stdlib/strtol_l.c, stdlib/strtold_l.c * stdlib/strtoll_l.c, stdlib/strtoul_l.c, stdlib/strtoull_l.c * string/strcasecmp.c, string/strcoll_l.c, string/string.h * string/strings.h, string/strncase.c, string/strxfrm_l.c * sysdeps/ieee754/float128/strtof128_l.c * sysdeps/ieee754/float128/wcstof128.c * sysdeps/ieee754/float128/wcstof128_l.c * sysdeps/ieee754/ldbl-128ibm/strtold_l.c * sysdeps/ieee754/ldbl-64-128/strtold_l.c * sysdeps/ieee754/ldbl-opt/nldbl-compat.c * sysdeps/ieee754/ldbl-opt/nldbl-strfmon_l.c * sysdeps/ieee754/ldbl-opt/nldbl-strtold_l.c * sysdeps/ieee754/ldbl-opt/nldbl-wcstold_l.c * sysdeps/powerpc/powerpc32/power7/strcasecmp.S * sysdeps/powerpc/powerpc64/power7/strcasecmp.S * sysdeps/x86_64/strcasecmp_l-nonascii.c * sysdeps/x86_64/strncase_l-nonascii.c, time/strftime_l.c * time/strptime_l.c, time/time.h, wcsmbs/mbsrtowcs_l.c * wcsmbs/wchar.h, wcsmbs/wcscasecmp.c, wcsmbs/wcsncase.c * wcsmbs/wcstod.c, wcsmbs/wcstod_l.c, wcsmbs/wcstof.c * wcsmbs/wcstof_l.c, wcsmbs/wcstol_l.c, wcsmbs/wcstold.c * wcsmbs/wcstold_l.c, wcsmbs/wcstoll_l.c, wcsmbs/wcstoul_l.c * wcsmbs/wcstoull_l.c, wctype/iswctype_l.c * wctype/towctrans_l.c, wctype/wcfuncs_l.c * wctype/wctrans_l.c, wctype/wctype.h, wctype/wctype_l.c: Change all uses of __locale_t to locale_t.	9 years ago
