From 9d96909913249f7b1ff9f503f8fa8abc458089a9 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 11 Dec 2014 07:17:11 -0500 Subject: powerpc: Fix lgammal_r overflow warnings ldbl-128ibm uses ldbl-128 e_lgammal_r implementation as is, however some constants definitions overflows for IBM long double range. This patch suppress the compiler warnings until the ldbl-128ibm implementation is fixed. --- sysdeps/ieee754/ldbl-128/e_lgammal_r.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) (limited to 'sysdeps') diff --git a/sysdeps/ieee754/ldbl-128/e_lgammal_r.c b/sysdeps/ieee754/ldbl-128/e_lgammal_r.c index 1961355a73..35d4a663ff 100644 --- a/sysdeps/ieee754/ldbl-128/e_lgammal_r.c +++ b/sysdeps/ieee754/ldbl-128/e_lgammal_r.c @@ -70,12 +70,20 @@ #include #include +#include +#include +/* BZ#16347: ldbl-128ibm uses this file as is, however the MAXLGM + definition overflows for IBM long double.
