2013-04-06i386: Fail at configure time for i386 builds.Carlos O'Donell
This change does two things: * Treats a target i386-* as if it were i686. * Fails configure if the user is generating code for i386. We no longer support i386 code-generation because the i386 lacks the atomic operations we need in glibc. You can still configure for i386-*, but you get i686 code. You can't build with --march=i386, --mtune=i386 or a compiler that defaults to i386 code-generation. I've added two i386 entries in the master todo list to discuss merging and renaming: http://sourceware.org/glibc/wiki/Development_Todo/Master#i386 The failure modes are fail-safe here. You compile for i386, get i686, and try to run on i386 and it fails. The configure log has a warning saying we elided to i686. There is no situation that I can see where we run into any serious problems. The patch makes the current state better in that we get less confused users and we build successfully in more default configurations. The next enhancement would be to add --march=i?86 as suggested in #c20 of BZ#10062 for any i?86-* builds, which would solve the problem of a 32-bit compiler that defaults to i386 code-gen and glibc configured for i686-* target. Which previously failed at build time, and now will fail at configure time (requires adding --march=i686). Updated NEWS with BZ #10060 and #10062. No regressions. --- 2013-04-06 Carlos O'Donell <carlos@redhat.com> [BZ #10060, #10062] * aclocal.m4 (LIBC_COMPILER_BUILTIN_INLINED): New macro. * sysdeps/i386/configure.in: Use LIBC_COMPILER_BUILTIN_INLINED and fail configure if __sync_val_compare_and_swap is not inlined. * sysdeps/i386/configure: Regenerate. * configure.in: Build for i686 when configured for i386. * configure: Regenerate. * README: Remove i386 reference.

2013-04-06s390/s390x: Undef PSEUDO before redef.Carlos O'Donell
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.

2013-04-04Add BZ #15337 to NEWSSiddhesh Poyarekar
2013-04-04Fix static build when configured with --disable-hidden-pltSiddhesh Poyarekar
Fixes BZ #15337. Static builds fail with the following warning: /home/tools/glibc/glibc/nptl/../nptl/sysdeps/unix/sysv/linux/x86_64/cancellation.S:80: undefined reference to `__GI___pthread_unwind' When the source is configured with --disable-hidden-plt. This is because the preprocessor conditional in cancellation.S only checks if the build is for SHARED, whereas hidden_def is defined appropriately only for a SHARED build that will have symbol versioning *and* hidden defs are enabled. The last case is false here.

2013-04-03Update bench.out and bench.out.old only upon completionSiddhesh Poyarekar
Write output from the currently running benchmark into a temporary file and move files around only once the current run is complete. That way we don't lose data from the last two runs due to an incomplete run.

2013-04-03Remove TWOSiddhesh Poyarekar
Minor cleanup to remove the macro TWO and use the value directly instead.
2013-04-03Preserve errno across _PC_CHOWN_RESTRICTED call on XFSSiddhesh Poyarekar
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.

Separate benchmarks for the fast and slow implementations of pow and exp since measuring both together doesn't make sense. Adjust the iterations for pow and exp accordingly so that they run long enough for the measurements to be meaningful.

2013-04-01PowerPC: remove branch prediction from rint implementationAdhemerval Zanella
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.

2013-03-28Don't add input group during initgroups_dyn in hesiodSiddhesh Poyarekar
Fixes BZ #15304. The *initgroups_dyn functions are called with a group argument. This group gid is usually skipped while populating the grouplist since the caller adds that group id in advance. The hesiod initgroups_dyn implementation however adds the group gid to the list if it does not already exist. While it works fine for the usual initgroups, it breaks nscd since it calls initgroups_dyn with -1 as the gid (to have all groups included).

2013-03-26Use integral constantsSiddhesh Poyarekar
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.

2013-03-26Make mantissa type of mp_no configurableSiddhesh Poyarekar
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.
