* s390/s390x: Undef PSEUDO before redef.Carlos O'Donell2013-04-062-0/+2
| | | | | | | | | | | | | | | | | | | The s390 and s390x sysdep.h files include the more generic sysdep.h. The more generic sysdep.h defines PSEUDO. This causes an annoying CPP warning saying the PSEUDO was redefined. This patch removes the warning by undefining PSEUDO before the redefinition. This is in line with what all the other machines do. --- 2013-04-06 Carlos O'Donell <carlos@redhat.com> * sysdeps/s390/s390-32/sysdep.h: Undefine PSEUDO before redefinition. * sysdeps/s390/s390-64/sysdep.h: Likewise. Notes: Added ChangeLog with this commit: b7a329a5614d9001abcc3300a3da548a0865a3ac

* Remove TWOSiddhesh Poyarekar2013-04-032-3/+1
| | | | | Minor cleanup to remove the macro TWO and use the value directly instead.
* Preserve errno across _PC_CHOWN_RESTRICTED call on XFSSiddhesh Poyarekar2013-04-032-0/+13
| | | | | | | | | | | | | | Fix BZ #15305. On kernel versions earlier than 2.6.29, the Linux kernel exported a sysctl called restrict_chown for xfs, which could be used to allow chown to users other than the owner. 2.6.29 removed this support, causing the open_not_cancel_2 to fail and thus modify errno. The fix is to save and restore errno so that the caller sees it as unmodified. Additionally, since the code to check the sysctl is not useful on newer kernels, we add an ifdef so that in future the code block gets rmeoved completely.

* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).Thomas Schwinge2013-04-0218-0/+345
| | | | It is based on draft TS 18661 and currently enabled as a GNU extension.
* PowerPC: remove branch prediction from rint implementationAdhemerval Zanella2013-04-014-12/+12
| | | | | | | | The branch prediction hints is actually hurts performance in this case. The assembly implementation make two assumptions: 1. 'fabs (x) < 2^52' is unlikely and 2. 'x > 0.0' is unlike (if 1. is true). Since it a general floating point function, expected input is not bounded and then it is better to let the hardware handle the branches.

* PowerPC: .eh_frame info in crt1.o isn't useful and triggers gold bug 14675.Alan Modra2013-03-282-0/+14
| | | | | | | The .eh_frame info in crt1.o isn't useful and this patch prevents it from being generated on PowerPC. It triggers the following gold bug: http://sourceware.org/bugzilla/show_bug.cgi?id=14675

|
* Use integral constantsSiddhesh Poyarekar2013-03-261-76/+76
| | | | | | The compiler is smart enough to convert those into double for powerpc, but if we put them as doubles, it adds overhead by performing those operations in floating point mode.
* Removed commented codeSiddhesh Poyarekar2013-03-2611-85/+0
|
* Make mantissa type of mp_no configurableSiddhesh Poyarekar2013-03-264-69/+157
| | | | | | | | | | The mantissa of mp_no is intended to take only integral values. This is a relatively good choice for powerpc due to its 4 fpus, but not for other architectures, which suffer due to this choice. This change makes the default mantissa a long integer and allows powerpc to override it. Additionally, some operations have been optimized for integer manipulation, resulting in a significant improvement in performance.

* BZ#13889: expl (709.75) wrongly overflows for ldbl-128ibmAdhemerval Zanella2013-03-222-6/+24
| | | | | | The patch increase the high value to check if expl overflows. Current high mark value is not really correct, the algorithm accepts high values. It also adds a correct wrapper function to check for overflow and underflow.
* BZ#11120: fix x86_64/strcmp.S NOT_IN_libc safeguardsDmitry V. Levin2013-03-221-3/+3
| | | | | | | | Due to a typo repeated several times, this bug hasn't been fixed yet, despite being marked as resolved in glibc 2.12. * sysdeps/x86_64/strcmp.S: Replace all occurrences of NOT_IN_lib with NOT_IN_libc.
