glibc 2.11 is very old, fma{,f,l} has been rewritten for glibc 2.14+. Please test that instead.
Jakub, the testsuite and the first two test fail for me on x86-64. The testsuite fails on 32-bit x86 as well but the two first tests pass. Test 1 on x86-64: Expected: 0X1.0000000000001P+54 Actual: 0X1P+54 Test 2 Expected: 0X1.FFFFFFFFFFFFFP+53 Actual: 0X1P+54 (In reply to comment #18) > Jakub, the testsuite and the first two test fail for me on x86-64.

Indeed, works for me now as well after removing some buggy routines. Let's close as Fixed for glibc 2.14+ Please add the first attachment to glibc's test suite. I see 6 different implementations of fma(), 4 implementations of fmaf(), and 4 implementations of fmal() in the glibc source code. How can you guarantee that all of them are thoroughly tested? The ones in math/s_fma.c, math/s_fmaf.c, math/s_fmal.c are definitely buggy. I've done quite a lot of testing on it back when it was added to glibc, see e.g. the http://sources.redhat.com/ml/libc-alpha/2010-10/txt00000.txt testcase (which has been tweaked for the other floating point formats (float, 80-bit long double, 128-bit long double). Yes, math/s_fma*.c won't DTRT, they are just fallback implementations for architectures without sufficient exception support (the real implementations rely on exceptions working properly and various fenv.h functions being available).

It would be even better - for the quality of future modifications - if a good unit test was in the glibc source tree. My proposed one runs in less than a second and was able to catch 16 different bugs (and does not need to link against mpfr or gmp). > Yes, math/s_fma*.c won't DTRT, they are just fallback implementations for > architectures without sufficient exception support Find attached a code that produces the correct result also regardless of exception support. Will soon be contributed to GNU gnulib. Should we replace math/s_fma{,f,l}.c with this code (after some polishing for glibc coding style)? Bruno Created attachment 6008 [details]
portable implementation of fma(), fmaf(), fmal(), code written for gnulib
I'll leave the decision whether to include the testcase into glibc or not to Ulrich, I'm not involved with glibc these days too much.
And I'm not sure if there are any supported targets that do currently use math/s_fma*.c.
BTW, your implementation will do the wrong thing if you call say
fma (DBL_MAX, DBL_MAX, -__builtin_inf (""));
will I think in your implementation return NaN, while it must be -Inf.
Among libc targets, there is one that fails to build fma* at present for lack of rounding mode support (and not being configured to use the incorrect fallbacks): no-FPU SH. Has it been tested in the directed rounding modes? Created attachment 6014 [details]

(In reply to comment #25) Jakub, > your implementation will do the wrong thing if you call say > fma (DBL_MAX, DBL_MAX, -__builtin_inf ("")); > will I think in your implementation return NaN, while it must be -Inf. Good point, yes. I've updated the attached test suite to check this, and fixed the attached implementation code. Thanks. Created attachment 6017 [details] portable implementation of fma(), fmaf(), fmal(), code written for gnulib, version 3 (In reply to comment #27) > Has it been tested in the directed rounding modes? A new version of the implementation code (attached) supports the 4 rounding modes. Let's reopen to discuss and decide on adding the portable implementation to glibc. Besides my implementation of a correct fma() on platforms without rounding mode support, there is also the one by Steven Munroe, in bug #3268: http://sourceware.org/bugzilla/attachment.cgi?id=1664 http://sourceware.org/bugzilla/attachment.cgi?id=1665 I cannot judge whether the glibc maintainers will prefer one or the other. I'm ready to convert the implementation code here to glibc style. Just let me know. Bruno I think we should go with something like this version (but of course under LGPLv2.1+ for glibc) for now - with the source file set up so the same file (apart from license notices and space/tab differences) can be used in both glibc and gnulib. A soft-fp version might be faster - but the one in bug 3268 is not a clean implementation using soft-fp (it relies on soft-fp knowing about a wider "quad" floating-point type, rather than having an internal _FP_FMA operation that uses more precision internally but without requiring a wider type). So I think we should use the portable implementation for math/s_fma{,f,l}.c for now. If in future there is a clean soft-fp implementation, that can then be used instead (the portable version would still be useful for ldbl-128ibm - as I understand, it will work as if that format uses a fixed 106 bit mantissa - unless and until there is an implementation specific to that format). *** Bug 3268 has been marked as a duplicate of this bug. *** Created attachment 6657 [details]

Please file a separate bug for this, and keep the present bug just for the
need for a better fallback implementation (where we're hoping for Bruno to
contribute a version of the gnulib code to glibc at some point).
FWIW, the ldbl-128ibm version of fmal, which I think would better be replaced by a generic version such as that discussed here (which would also be useful for platforms without FE_INEXACT / FE_TOWARDZERO), not only is incorrect in that it doesn't provide a fused operation, but also appears to produce results that are actually invalid long double values, when in directed rounding modes, e.g.: Failure: Test: fma_towardzero (max_value, max_value, min_value) == max_value Result: is: 1.79769313486231590772e+308 0x1.ffffffffffffffffffffp+1023 should be: 1.79769313486231580793e+308 0x1.fffffffffffff7ffffffp+1023 difference: 1.79769313486231550856e+308 0x1.ffffffffffffe0000000p+1023 ulp : 81129638414606663681390495662080.0000 max.ulp : 0.0000 (Such edges cases for ldbl-128ibm might end up as separate issues, but it probably doesn't make sense to file such separate issues for them until fmal for ldbl-128ibm is basically right, most likely through use of a generic implementation.) We now have soft-fp fma available for use by systems without the exceptions and rounding mode support required for the main fma implementations using rounding-to-odd to work. commit 77f01ab5d1d2eead1bd4a9135d6a76ebd3fe21e5 Author: Joseph Myers <joseph@codesourcery.com> Date: Tue Jul 2 14:55:32 2013 +0000 Implement fma in soft-fp.

Use soft-fp fma for MicroBlaze (bug 13304).
Systems without floating-point exceptions and rounding modes should
use the soft-fp versions of fmaf and fma, not the sysdeps/ieee754
versions that rely on setting rounding to zero and testing for the
"inexact" exception; this has been noted on
<https://sourceware.org/glibc/wiki/PortStatus> for some time. This
patch makes MicroBlaze use the soft-fp files; sfp-machine.h is made to
include the nios2 version of sfp-machine.h which seems sufficiently
generic for 32-bit systems.

The GNU C Library
=================
The GNU C Library version 2.23 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.23 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.23
=====================
* Unicode 8.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 8.0.0, using new
and/or improved generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, such as the fixes for bugs
89, 16061, and 18568.
* sched_setaffinity, pthread_setaffinity_np no longer attempt to guess the
kernel-internal CPU set size. This means that requests that change the
CPU affinity which failed before (for example, an all-ones CPU mask) will
now succeed. Applications that need to determine the effective CPU
affinities need to call sched_getaffinity or pthread_getaffinity_np after
setting it because the kernel can adjust it (and the previous size check
would not detect this in the majority of cases).
* The fts.h header can now be used with -D_FILE_OFFSET_BITS=64. With LFS
the following new symbols are used: fts64_children, fts64_close,
fts64_open, fts64_read and fts64_set.
* getaddrinfo now detects certain invalid responses on an internal netlink
socket. If such responses are received, an affected process will
terminate with an error message of "Unexpected error <number> on netlink
descriptor <number>" or "Unexpected netlink response of size <number> on
descriptor <number>". The most likely cause for these errors is a
multi-threaded application which erroneously closes and reuses the netlink
file descriptor while it is used by getaddrinfo.
* A defect in the malloc implementation, present since glibc 2.15 (2012) or
glibc 2.10 via --enable-experimental-malloc (2009), could result in the
unnecessary serialization of memory allocation requests across threads.
The defect is now corrected. Users should see a substantial increase in
the concurent throughput of allocation requests for applications which
trigger this bug. Affected applications typically create create and
destroy threads frequently. (Bug 19048 was reported and analyzed by
Ericsson.)
* There is now a --disable-timezone-tools configure option for disabling the
building and installing of the timezone related utilities (zic, zdump, and
tzselect). This is useful for people who build the timezone data and code
independent of the GNU C Library.
* The obsolete header <regexp.h> has been removed. Programs that require
this header must be updated to use <regex.h> instead.
* The obsolete functions bdflush, create_module, get_kernel_syms,
query_module and uselib are no longer available to newly linked binaries;
the header <sys/kdaemon.h> has been removed. These functions and header
were specific to systems using the Linux kernel and could not usefully be
used with the GNU C Library on systems with version 2.6 or later of the
Linux kernel.
* Optimized string, wcsmbs and memory functions for IBM z13.
Implemented by Stefan Liebler.
* Newly linked programs that define a variable called signgam will no longer
have it set by the lgamma, lgammaf and lgammal functions. Programs that
require signgam to be set by those functions must ensure that they use the
variable provided by the GNU C Library and declared in <math.h>, without
defining their own copy.
* The minimum GCC version that can be used to build this version of the GNU
C Library is GCC 4.7. Older GCC versions, and non-GNU compilers, can
still be used to compile programs using the GNU C Library.
Security related changes:
* An out-of-bounds value in a broken-out struct tm argument to strftime no
longer causes a crash. Reported by Adam Nielsen. (CVE-2015-8776)
* The LD_POINTER_GUARD environment variable can no longer be used to disable
the pointer guard feature. It is always enabled. Previously,
LD_POINTER_GUARD could be used to disable security hardening in binaries
running in privileged AT_SECURE mode. Reported by Hector Marco-Gisbert.
(CVE-2015-8777)
* An integer overflow in hcreate and hcreate_r could lead to an
out-of-bounds memory access. Reported by Szabolcs Nagy. (CVE-2015-8778)
* The catopen function no longer has unbounded stack usage. Reported by
Max. (CVE-2015-8779)
* The nan, nanf and nanl functions no longer have unbounded stack usage
depending on the length of the string passed as an argument to the
functions. Reported by Joseph Myers. (CVE-2014-9761)
* A stack-based buffer overflow was found in libresolv when invoked from
libnss_dns, allowing specially crafted DNS responses to seize control
of execution flow in the DNS client. The buffer overflow occurs in
the functions send_dg (send datagram) and send_vc (send TCP) for the
NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC
family. The use of AF_UNSPEC triggers the low-level resolver code to
send out two parallel queries for A and AAAA. A mismanagement of the
buffers used for those queries could result in the response of a query
writing beyond the alloca allocated buffer created by
_nss_dns_gethostbyname4_r. Buffer management is simplified to remove
the overflow. Thanks to the Google Security Team and Red Hat for
reporting the security impact of this issue, and Robert Holiday of
Ciena for reporting the related bug 18665. (CVE-2015-7547)

commit ffe9aaf2b9b7e297924b9fcf76ad854e6b97869b
Author: Joseph Myers <joseph@codesourcery.com>
Date: Thu May 19 20:10:56 2016 +0000
Implement proper fmal for ldbl-128ibm (bug 13304).
ldbl-128ibm had an implementation of fmal that just did (x * y) + z in
most cases, with no attempt at actually being a fused operation.
This patch replaces it with a genuine fused operation. It is not
necessarily correctly rounding, but should produce a result at least
as accurate as the long double arithmetic operations in libgcc, which
I think is all that can reasonably be expected for such a non-IEEE
format where arithmetic is approximate rather than rounded according
to any particular rule for determining the exact result. Like the
libgcc arithmetic, it may produce spurious overflow and underflow
results, and it falls back to the libgcc multiplication in the case of
(finite, finite, zero).
This concludes the fixes for bug 13304; any subsequently found fma
issues should go in separate Bugzilla bugs. Various other pieces of
bug 13304 were fixed in past releases over the past several years.
Tested for powerpc.
[BZ #13304]
* sysdeps/ieee754/ldbl-128ibm/s_fmal.c: Include <fenv.h>,
<float.h>, <math_private.h> and <stdlib.h>.
(add_split): New function.
(mul_split): Likewise.
(ext_val): New typedef.
(store_ext_val): New function.
(mul_ext_val): New function.
(compare): New function.
(add_split_ext): New function.
(__fmal): After checking for Inf, NaN and zero, compute result as
an exact sum of scaled double values in round-to-nearest before
adding those up and adjusting for other rounding modes.
* math/auto-libm-test-in: Remove xfail-rounding:ldbl-128ibm from
tests of fma.
* math/auto-libm-test-out: Regenerated.

The GNU C Library
=================
The GNU C Library version 2.24 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.24 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.24
=====================
* The minimum Linux kernel version that this version of the GNU C Library
can be used with is 3.2, except on i[4567]86 and x86_64, where Linux
kernel version 2.6.32 or later suffices (on architectures that already
required kernel versions more recent than 3.2, those requirements remain
unchanged). Linux 3.2 or later kernel headers are required on all
architectures.
* The pap_AN locale has been deleted. This has been deprecated for a long
time. It has been replaced by pap_AW & pap_CW, both of which have long
been included in previous releases.
* The readdir_r and readdir64_r functions have been deprecated. It is
recommended to use readdir and readdir64 instead.
* The type “union wait” has been removed. It was deprecated in the early
1990s and never part of POSIX. Application code should use the int type
instead of “union wait”.
* A new NSS action is added to facilitate large distributed system
administration. The action, MERGE, allows remote user stores like LDAP
to be merged into local user stores like /etc/groups in order to provide
easy to use, updated, and managed sets of merged credentials. The new
action can be used by configuring it in /etc/nsswitch.conf:
group: files [SUCCESS=merge] nis
Implemented by Stephen Gallagher (Red Hat).
* The deprecated __malloc_initialize_hook variable has been removed from the
API.
* The long unused localedef --old-style option has been removed. It hasn't
done anything in over 16 years. Scripts using this option can safely
drop it.
* nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf are added to
libm. They are defined by TS 18661 and IEEE754-2008. The nextup functions
return the next representable value in the direction of positive infinity
and the nextdown functions return the next representable value in the
direction of negative infinity. These are currently enabled as GNU
extensions.
Security related changes:
* An unnecessary stack copy in _nss_dns_getnetbyname_r was removed. It
could result in a stack overflow when getnetbyname was called with an
overly long name. (CVE-2016-3075)
* Previously, getaddrinfo copied large amounts of address data to the stack,
even after the fix for CVE-2013-4458 has been applied, potentially
resulting in a stack overflow. getaddrinfo now uses a heap allocation
instead. Reported by Michael Petlan. (CVE-2016-3706)
* The glob function suffered from a stack-based buffer overflow when it was
called with the GLOB_ALTDIRFUNC flag and encountered a long file name.
Reported by Alexander Cherepanov. (CVE-2016-1234)
* The Sun RPC UDP client could exhaust all available stack space when
flooded with crafted ICMP and UDP messages. Reported by Aldy Hernandez'
alloca plugin for GCC. (CVE-2016-4429)
* The IPv6 name server management code in libresolv could result in a memory
leak for each thread which is created, performs a failing naming lookup,
and exits. Over time, this could result in a denial of service due to
memory exhaustion. Reported by Matthias Schiffer. (CVE-2016-5417)
