RFA: Port maintainers: Convert WORDSIZE[32|64]/ld to abi-variants
http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22382
<pre>Hi, Glibc Port Maintainers,
Here is a patch to convert WORDSIZE[32|64]/ld in shlib-versions to
abi-variants in CPU/Makefile to support more than one ABI in
gnu/lib-names.h, gnu/stubs.h and bits/syscall.h:
1. For non-biarch architectures, there is nothing to do.
2. For biarch/triarch architectures where there are no soname differences,
you need to rename syscall-list-* variables in CPU/Makefile to abi-*.
If the default ABI for the build isn't the first one on abi-variants, you
should also define default-abi:
---
# The default ABI is 64.
default-abi := 64
---
3. For biarch/triarch architectures where there are soname differences,
in addition to renaming syscall-list-* variables in CPU/Makefile to
abi-* and defining default-abi, you also need to define
abi-XX-ld-soname := your ld.so soname.
where XX is the ABI variant, like
---
# We don't need any header files.
abi-includes :=
abi-variants := 32 64 x32
abi-32-options := -D__i386__ -U__x86_64__
abi-32-condition := !defined __x86_64__
abi-32-ld-soname := ld-linux.so.2
abi-64-options := -U__i386__ -D__x86_64__ -U__ILP32__ -D__LP64__
abi-64-condition := defined __x86_64__ && defined __LP64__
abi-64-ld-soname := ld-linux-x86-64.so.2
abi-x32-options := -U__i386__ -D__x86_64__ -D__ILP32__ -U__LP64__
abi-x32-condition := defined __x86_64__ && defined __ILP32__
abi-x32-ld-soname := ld-linux-x32.so.2
----
Please test it and let me know if it works for you.
BTW, this patch is on hjl/abi branch.
Thanks.
H.J.

</pre>H.J. Lu2012-05-26T13:36:41X32 is almost done
http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22365
<pre>Hi,
Thanks for everyone, x32 is almost done. The last remaining issue is
http://sourceware.org/bugzilla/show_bug.cgi?id=14112
I have a proposal on hjl/abi branch. I updated x32 wiki page:
http://sourceware.org/glibc/wiki/x32
to describe how to bootstrap x32 GCC and GLIBC. I verified the procedure
on openSUSE 12.1:

</pre>H.J. Lu2012-05-25T22:22:34[PATCH] Fix underflow and inexact signalling in soft-fp when packing.
http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22363
<pre>
This fixes the long double math testsuite regressions that started
showing up on Sparc with Joseph's recent change to check underflow.
The corresponding changes needed in glibc-ports for powerpc/nofp,
mips, and alpha should be pretty straightforward.
In the main glibc tree, sparc is the only consumer of this code.
Ok to commit?
* soft-fp/op-common.h (_FP_PACK_CANONICAL): Only set underflow if
the underflow exception is enabled and the non-zero result is
tiny, or the non-zero result is tiny and there will be a loss of
accuracy. Set inexact if overflow is detected after rounding, but
not if it is detected before.
* soft-fp/soft-fp.h (FP_CUR_EXCEPTIONS): Define.
(FP_TRAPPING_EXCEPTIONS): Provide default define.
* sysdeps/sparc/sparc32/soft-fp/sfp-machine.h (_FP_DECL_EX):
Initialize _fcw to zero.
(FP_TRAPPING_EXCEPTIONS): Define.
(FP_HANDLE_EXCEPTIONS): Add dummy use of _fcw.
* sysdeps/sparc/sparc64/soft-fp/sfp-machine.h (_FP_DECL_EX):
Initialize _fcw to zero.
(FP_TRAPPING_EXCEPTIONS): Define.
(FP_HANDLE_EXCEPTIONS): Add dummy use of _fcw.

</pre>David Miller2012-05-25T22:09:16Remove __ASSUME_NEW_GETRLIMIT_SYSCALL
http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22361
<pre>__ASSUME_NEW_GETRLIMIT_SYSCALL is defined in kernel-features.h for x86
and powerpc, and in ports for arm, for m68k (>= 2.4.12) and tile. It
is used in sysdeps/unix/sysv/linux/i386/getrlimit.c and
sysdeps/unix/sysv/linux/i386/setrlimit.c. Those files are in turn
included for powerpc, s390-32, sh and (in ports) am33, arm and m68k.
This relates to system calls now called ugetrlimit and setrlimit. As
of 2.4.0-test1, s390, sh and m68k all have those syscalls wired up
(this is about the syscall tables rather than what's in asm/unistd.h,
since we already require >= 2.6.19.1 kernel headers). So although
those architectures do not define __ASSUME_NEW_GETRLIMIT_SYSCALL (at
all, or for 2.4.0 in the case of m68k) it's nevertheless safe to
assume the syscalls to be present for those architectures. Finally,
am33 (mn10300) support was added in 2.6.25, and when added the support
for those syscalls was present (and kernel versions before support for
an architecture was officially added to Linux are not of concern to
glibc).
Thus it is safe to remove the conditionals on this macro, and the
definitions of this macro. I propose this patch to do so. Tested
x86.

http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22354
<pre>Hi,
Here is the patch adapted from the patch for the same problem in libgcc:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53183
When we configure glibc, we shouldn't use any headers. Tested on
Linux/ia32,x32,x86-64. There are no changes in config.h nor config.make.
OK to install?
Thanks.
H.J.

http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22344
<pre>Greetings,
Using glibc-2.15 to compile this file:
#include <sys/select.h>
int foo(int fd) {
fd_set fds;
FD_SET(fd, &fds);
return FD_ISSET(fd, &fds);
}
with 'gcc -O2 -D_FORTIFY_SOURCE=2 -Werror=sign-conversion -c t.c', results in:
t.c: In function 'foo':
t.c:4: error: conversion to 'long unsigned int' from 'int' may change the sign of the result
t.c:5: error: conversion to 'long unsigned int' from 'int' may change the sign of the result
Attached trivial patch fixes that.
Thanks,

http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22314
<pre>
Hey Joseph, just FYI your test to add underflow exceptions to
libm-test.inc is causing long double testsuite failures on 64-bit
sparc.
Specifically:
testing long double (without inline functions)
Failure: exp2 (-16400) == 0x1p-16400: Exception "Underflow" set
Failure: scalbn (min_value / 4, INT_MAX) == inf: Exception "Underflow" set
Failure: scalbln (min_value / 4, INT_MAX) == inf: Exception "Underflow" set
Failure: scalbln (min_value / 4, LONG_MAX) == inf: Exception "Underflow" set
Failure: scalbln (min_value / 4, 0x88000000) == inf: Exception "Underflow" set
Test suite completed:
5478 test cases plus 4610 tests for exception flags executed.
5 errors occurred.
I'll try to dig more deeply but I figured you might be able to tell
offhand whether this is some generic issue on 64-bit cpus or that
it might be prudent to relax the requirements.
</pre>David Miller2012-05-25T00:11:32PATCH: Convert WORDSIZE[32|64] to abi-variants
http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22311
<pre>Hi,
I extended syscall-list support to cover all generated files on hjl/abi
branch. If a target supports more than one ABI, it can define the
appropriate abi-*-*, like sysdeps/unix/sysv/linux/x86_64/Makefile has
# We don't need any header files.
abi-includes :=
abi-32-options := -D__i386__ -U__x86_64__
abi-32-condition := !defined __x86_64__
abi-32-ld-soname := ld-linux.so.2
abi-64-options := -U__i386__ -D__x86_64__ -U__ILP32__ -D__LP64__
abi-64-condition := defined __x86_64__ && defined __LP64__
abi-64-ld-soname := ld-linux-x86-64.so.2
abi-x32-options := -U__i386__ -D__x86_64__ -D__ILP32__ -U__LP64__
abi-x32-condition := defined __x86_64__ && defined __ILP32__
abi-x32-ld-soname := ld-linux-x32.so.2
abi-variants is a list of ABIs and
sysdeps/unix/sysv/linux/x86_64/64/Makefile has
# The default ABI is 64.
default-abi := 64
We have duplicated information of ld-soname in shlib-versions and
sysdeps/unix/sysv/linux/x86_64/Makefile. I can use the ld soname
in CPU/Makefile for everything. Any comments?
Thanks.
H.J.

</pre>H.J. Lu2012-05-24T23:26:39Fix acosf underflow (bug 14153)
http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22300
<pre>Bug 14153 is a spurious underflow exception from acosf (2e-17); the
cause is the acosf implementation calculating a value on the order of
the cube of its argument, which underflows. There is a test for very
small arguments, maybe to avoid underflow, and if such an argument is
encountered it returns pi/2 (computed by adding high and low parts, I
suppose to get correct results for the current rounding mode and to
raise the inexact exception). However, this tests for values no more
than 2**-57, as if the test was unchanged from a "double" version of
the function; it suffices to test for values no more than 2**-26,
which avoids the problem with internal underflows. (For small x, the
correct value is essentially pi/2 - x. Compute pi/2 rounded to 25
bits - one more bit than float - which is the nearest value that is
representable as float or half way between two representable values.
Compute the difference of pi/2 and that rounded values; if |x| is
smaller than that difference then the result of rounding pi/2 - x will
be the same in any rounding mode as the result of rounding pi/2. Now
that difference is more than 2**-26.)
I propose this patch fixing the bug that way. Tested x86_64 and x86.

http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22298
<pre>The roland/systemtap branch has been lingering for quite some time.
It never got merged, but there were never any coherent objections IIRC.
Related past threads I found:
http://sourceware.org/ml/libc-alpha/2011-03/msg00001.html
http://sourceware.org/ml/libc-alpha/2011-02/msg00003.html
http://sourceware.org/ml/libc-alpha/2011-01/msg00008.html
I believe Fedora has been using this code since Fedora 15.
(I have Fedora 16/x86_64 handy and its libc.so.6 has the notes.)
I've just rebased the branch, fixed conflicts, updated copyright years
and log entries, and adapted the x86_64 assembly bits for x32. (The
x86_64 pthread probes written in assembly use unadorned register
names, indicating 64-bit quantities for pointer values on x32, but I
don't think it really matters.)
I've tested the build on x86_64 but not really tested using the probes
with stap or gdb. I just eyeballed the notes with 'readelf -n' and
they all look fine.
Are there any objections to (or endorsements for) merging the branch now?
The changes still have no effect without --enable-systemtap.
Thanks,
Roland
</pre>Roland McGrath2012-05-24T21:26:23PATCH: Make chunk size a multiple of MALLOC_ALIGNMENT
http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22286
<pre>Hi,
do_check_free_chunk has
static void do_check_free_chunk(mstate av, mchunkptr p)
{
INTERNAL_SIZE_T sz = p->size & ~(PREV_INUSE|NON_MAIN_ARENA);
mchunkptr next = chunk_at_offset(p, sz);
do_check_chunk(av, p);
/* Chunk must claim to be free ... */
assert(!inuse(p));
assert (!chunk_is_mmapped(p));
/* Unless a special marker, must have OK fields */
if ((unsigned long)(sz) >= MINSIZE)
{
assert((sz & MALLOC_ALIGN_MASK) == 0);
If a free chunk >= MINSIZE, it must be a multiple of MALLOC_ALIGNMENT.
However, when sysmalloc frees old top chunk with size >= MINSIZE, it
doesn't make sure that the size is a multiple of MALLOC_ALIGNMENT:
/* Setup fencepost and free the old top chunk. */
/* The fencepost takes at least MINSIZE bytes, because it might
become the top chunk again later. Note that a footer is set
up, too, although the chunk is marked in use. */
old_size -= MINSIZE;
set_head(chunk_at_offset(old_top, old_size + 2*SIZE_SZ), 0|PREV_INUSE);
if (old_size >= MINSIZE) {
set_head(chunk_at_offset(old_top, old_size), (2*SIZE_SZ)|PREV_INUSE);
set_foot(chunk_at_offset(old_top, old_size), (2*SIZE_SZ));
set_head(old_top, old_size|PREV_INUSE|NON_MAIN_ARENA);
_int_free(av, old_top, 1);
} else {
This bug caused some test failures in one of nss packages on Linux/x32.
This patch fixes it. OK to install?
Thanks.

http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22279
<pre>
I've recently had the need to review glibc's vfprintf code. During the
process I discovered that no testcase for bug #13446 was ever installed.
The original testcase in #13446 utilizes the printf hooks mechanism; the
system where I needed the problem fixed & tested pre-dates printf hooks,
so I mangled the existing stdio-common/bug23.c test to expose the memory
allocation bug in #13446.
OK to install?

</pre>H.J. Lu2012-05-24T13:10:33Don't include exceptions in libm-test-ulps test names
http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22260
<pre>As noted in my underflow patch, the names of libm tests that appear in
libm-test-ulps include a description of the tests for exceptions.
This can cause undue churn in the libm-test-ulps files. In
particular, if a test is made to permit an exception until a bug about
that spurious exception is fixed (with a comment referencing the bug
beside the test in question), then ulps for that test need updating,
and when the bug is fixed they need updating again, whether or not the
fix actually changed the value returned by the function.
I think this outweighs any value in actually having these
descriptions, and propose this patch which removes the exception
descriptions from the test names (and makes the corresponding
mechanical updates to libm-test-ulps files). Tested x86 and x86_64.
2012-05-24 Joseph Myers <joseph< at >codesourcery.com>
* math/gen-libm-test.pl (%beautify): Remove entries for exceptions
and other flags.
(special_function): Do not include flags in test name.
(parse_args): Likewise.
* sysdeps/i386/fpu/libm-test-ulps: Update.
* sysdeps/powerpc/fpu/libm-test-ulps: Likewise.

http://comments.gmane.org/gmane.comp.lib.glibc.alpha/22249
<pre>Although we have various bug reports referring to missing or spurious
underflow exceptions from libm functions, the libm-test machinery
doesn't support testing for such exceptions. I propose this patch to
add such support. I decided to treat underflow exceptions like the
others tested for - that is, say that we should consider spurious
underflow exceptions to be bugs, although they are generally allowed
by C99 Annex F. (However, in cases of exact results that are
subnormal or very close to subnormal I generally allow the exceptions
rather than requiring accurate detection of inexactness - recall that
exact underflow does not raise the exception in IEEE 754-2008.)
This will allow testcases to be added for the
missing-underflow-exception bugs that were fixed by the use of
-frounding-math to build glibc.
Tested x86 and x86_64. The ulps changes are because the "name" of a
test, used in the test's output as well as ulps files, includes a
description of the expected exceptions.
