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. --- ChangeLog | 5 +++++ sysdeps/ieee754/ldbl-128/e_lgammal_r.c | 10 +++++++++- 2 files changed, 14 insertions(+), 1 deletion(-) diff --git a/ChangeLog b/ChangeLog index ef4b50e..37da9a7 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,8 @@ +2014-12-11 Adhemerval Zanella + + * sysdeps/ieee754/ldbl-128/e_lgammal_r.c: Remove overflow warnings for + constants definition. + 2014-12-11 Andreas Schwab [BZ #16657] diff --git a/sysdeps/ieee754/ldbl-128/e_lgammal_r.c b/sysdeps/ieee754/ldbl-128/e_lgammal_r.c index 1961355..35d4a66 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.
