From 8278d50ce7f48dc5af68fac850192c7666661cd4 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 30 Sep 2016 15:08:08 +0000 Subject: Fix ldbl-128ibm iscanonical for -mlong-double-64. This patch fixes the ldbl-128ibm version of the iscanonical macro not to use __iscanonicall when long double = double (-mlong-double-64). Tested for powerpc. * sysdeps/ieee754/ldbl-128ibm/bits/iscanonical.h [__NO_LONG_DOUBLE_MATH] (__iscanonicall): Do not declare. [__NO_LONG_DOUBLE_MATH] (iscanonical): Define to evaluate to 1. --- sysdeps/ieee754/ldbl-128ibm/bits/iscanonical.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'sysdeps/ieee754') diff --git a/sysdeps/ieee754/ldbl-128ibm/bits/iscanonical.h b/sysdeps/ieee754/ldbl-128ibm/bits/iscanonical.h index cbc79ae..c7b7c63 100644 --- a/sysdeps/ieee754/ldbl-128ibm/bits/iscanonical.h +++ b/sysdeps/ieee754/ldbl-128ibm/bits/iscanonical.h @@ -20,6 +20,9 @@ # error "Never use directly; include instead." #endif +#ifdef __NO_LONG_DOUBLE_MATH +# define iscanonical(x) ((void) (__typeof (x)) (x), 1) +#else extern int __iscanonicall (long double __x) __THROW __attribute__ ((__const__)); @@ -29,7 +32,8 @@ extern int __iscanonicall (long double __x) conversion, before being discarded; in IBM long double, there are encodings that are not consistently handled as corresponding to any particular value of the type, and we return 0 for those. */ -#define iscanonical(x) \ +# define iscanonical(x) \ (sizeof (x) == sizeof (long double) \ ? __iscanonicall (x) \ : ((void) (__typeof (x)) (x), 1)) +#endif -- cgit v1.1
