From: "rsa at us dot ibm dot com" <sourceware-bugzilla@sourceware.org> To: glibc-bugs@sources.redhat.com Subject: [Bug libc/6824] New: Usage of __LONGDOUBLE128 instead of __LONG_DOUBLE_128__ causes PowerPC checklocal-plt make check failure Date: Thu, 07 Aug 2008 21:59:00 -0000 [thread overview] Message-ID: <20080807215839.6824.rsa@us.ibm.com> (raw) Erroneous usage of __LONGDOUBLE128 (which was introduced to GCC for AIX support) was causing mathinline.h to lack an implementation of __signbitl for powerpc32. This caused checklocal-plt make check failure for PowerPC. The correct define to use is __LONG_DOUBLE_128__. diff -X /home/ryanarn/bin/dontdiff -uNr glibc/sysdeps/unix/sysv/linux/powerpc/bits/mathinline.h glibc.new/sysdeps/unix/sysv/linux/powerpc/bits/mathinline.h --- glibc/sysdeps/unix/sysv/linux/powerpc/bits/mathinline.h 2008-08-07 10:54:03.000000000 -0500 +++ glibc.new/sysdeps/unix/sysv/linux/powerpc/bits/mathinline.h 2008-08-07 16:17:36.000000000 -0500 @@ -72,7 +72,7 @@ __extension__ union { double __d; int __i[2]; } __u = { __d: __x }; return __u.__i[0] < 0; } -# ifdef __LONGDOUBLE128 +# ifdef __LONG_DOUBLE_128__ __MATH_INLINE int __NTH (__signbitl (long double __x)) { I'll post this to mainline with a ChangeLog after full testing with GCC 4.1 & GCC 4.3 compilers and on different PowerPC arches. -- Summary: Usage of __LONGDOUBLE128 instead of __LONG_DOUBLE_128__ causes PowerPC checklocal-plt make check failure Product: glibc Version: 2.8 Status: NEW Severity: normal Priority: P2 Component: libc AssignedTo: drepper at redhat dot com ReportedBy: rsa at us dot ibm dot com CC: glibc-bugs at sources dot redhat dot com GCC build triplet: powerpc64-linux GCC host triplet: powerpc64-linux GCC target triplet: powerpc64-linux http://sourceware.org/bugzilla/show_bug.cgi?id=6824 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
