Correctly size profiling reloc table (bug 17411)
During auditing or profiling modes the dynamic loader
builds a cache of the relocated PLT entries in order
to reuse them when called again through the same PLT
entry. This way the PLT entry is never completed and
the call into the resolver always results in profiling
or auditing code running.
The problem is that the PLT relocation cache size
is not computed correctly. The size of the cache
should be "Size of a relocation result structure"
x "Number of PLT-related relocations". Instead the
code erroneously computes "Size of a relocation
result" x "Number of bytes worth of PLT-related
relocations". I can only assume this was a mistake
in the understanding of the value of DT_PLTRELSZ
which is the number of bytes of PLT-related relocs.
We do have a DT_RELACOUNT entry, which is a count
for dynamic relative relocs, but we have no
DT_PLTRELCOUNT and thus we need to compute it.
This patch corrects the computation of the size of the
relocation table used by the glibc profiling code.

Remove shlib-versions entries redundant with DEFAULT entries.
When a shlib-versions file has a DEFAULT line, it's not necessary to
specify the same default minimum symbol version on the lines for
individual libraries. If those lines otherwise duplicate the default
SONAME for the library in question, they can be removed completely.
This patch makes such cleanups: version entries for ld.so are removed
(leaving just the definition of the architecture-specific dynamic
linker name) and entries for libpthread are removed completely (since
the default is libpthread.so.0).
Tested for x86_64 that the installed shared libraries are unchanged by
this patch.
There are various architectures (hppa, ia64, mips, sh, sparc64) that
define minimum symbol versions (or in the case of mips, omission of
symbol versions) only for particular libraries without a DEFAULT line.
None of these are equivalent to something simpler with a DEFAULT line
because all have some other libraries, not explicitly mentioned, with
symbol versions that would be omitted were such a line used. In the
mips case I'm pretty sure it was a mistake not to omit the 2.1 symbols
for libthread_db; for the others I don't know if it was a mistake or
deliberate that some symbols in various libraries have 2.0 or 2.1
versions despite other libraries having a 2.2 minimum.
This concludes the shlib-versions cleanups I'm aware of.

Clean up gnu/lib-names.h generation (bug 14171).
This patch eliminates the mixture of SONAME information in
shlib-versions files and SONAME information used to generate
gnu/lib-names.h in makefiles, with the information in the makefiles
being removed so all this information comes from the shlib-versions
files.
So that gnu/lib-names.h supports multiple ABIs, it is changed to be
generated on the same basis as gnu/stubs.h: when there are multiple
ABIs, gnu/lib-names.h is a wrapper header (the same header installed
whatever ABI is being built) and separate headers such as
gnu/lib-names-64.h contain the substantive contents (only one such
header being installed by any glibc build).
The rules for building gnu/lib-names.h were moved from Makeconfig to
Makerules because they need to come after sysdeps makefiles are
included (now that "ifndef abi-variants" is a toplevel conditional on
the rules rather than $(abi-variants) being evaluated later inside the
commands for a rule).
Tested for x86_64 and x86 that the installed shared libraries are
unchanged by this patch, and examined the installed gnu/lib-names*.h
headers by hand. Also tested the case of a single ABI (where there is
just a single header installed, again like stubs.h) by hacking
abi-variants to empty for x86_64.

Move some setrlimit definitions to syscalls.list (bug 14138).
Bug 14138 is followup cleanup after removal of support for old Linux
kernel versions: moving syscalls to syscalls.list where the only
reason for using C definitions was kernel version conditionals that
are no longer present.
This patch deals with the case of setrlimit
(sysdeps/unix/sysv/linux/i386/setrlimit.c, included by various other
architectures). Where needed (where there is also a compat symbol for
setrlimit@GLIBC_2.0), new syscalls.list entries are added. Where not
needed (where there is no such compat symbol and the minimum symbol
version for libc is 2.2 or later), no such entries are added as that
in sysdeps/unix/syscalls.list will suffice. Thus arm and sh need no
such entries, while m68k and powerpc need entries only in a
subdirectory syscalls.list file rather than for all configurations
that previously used setrlimit.c.
(setrlimit@@GLIBC_2.2 and setrlimit@GLIBC_2.0 are now semantically
identical - the new symbol version was about a change of types from
signed to unsigned and the former compatibility code for dealing with
large unsigned arguments on old kernels is no longer needed or
present, having been removed with support for pre-2.4 kernels.
However, making the two versions into aliases doesn't work at present:
the case of having both default and non-default symbol versions on the
same syscalls.list line results in a compat_symbol call in code built
for static libc, which doesn't compile. I don't suppose it would be
hard to generate SHARED conditionals from make-syscalls.sh to fix
this, but in any case this patch doesn't make things any worse, as the
functions weren't aliases before the patch either.)
Tested for x86, and ran ABI tests for ARM as an example of an
architecture where the setrlimit.c file was just removed without
adding syscalls.list entries.

Revert to defining __extern_inline only for gcc-4.3+ (BZ #17266)
The check for only __GNUC_STDC_INLINE__ and __GNUC_GNU_INLINE__ may
not be sufficient since those flags were added during initial support
for C99 inlining semantics. There is also a problem with always
defining __extern_inline and __extern_always_inline, since it enables
inline wrapper functions even when GNU inlining semantics are not
guaranteed. This, along with the possibility of such wrappers using
redirection (btowc for example) could result in compiler generating an
infinitely recusrive call to the function.
In fact it was such a recursion that led to this code being written
the way it was; see:
https://bugzilla.redhat.com/show_bug.cgi?id=186410
The initial change was to fix bugs 14530 and 13741, but they can be
resolved by checking if __fortify_function and/or
__extern_always_inline are defined, as it has been done in this patch.
In addition, I have audited uses of __extern_always_inline to make

There is however a regression in this patch for llvm, since it reverts
the llvm expectation that __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__
definition imply proper extern inline semantics.

Use %ifdef in sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions.
This patch makes
sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions use %ifdef
conditionals around the different symbol version definitions for big

for those definitions; the point is to make it possible to remove the
first column from shlib-versions by eliminating the last case where it
would be harmful for it to be treated as .*-.*-.*.) The conditional
is based on the ELFv1/ELFv2 distinction rather than BE/LE, since
that's what's already tested in configure and used for the ld.so
soname in the Makefiles. (Of course if BE ELFv2 were supported in
future, it would get new symbol versions and so need new
conditionals.)

Move architecture-specific shlib-versions entries to sysdeps files.
This patch eliminates another way in which ex-ports and non-ex-ports
architectures differ, by moving architecture-specific entries from the
top-level shlib-versions file and that in nptl/ to appropriate sysdeps
directories. As with my previous patch
<https://sourceware.org/ml/libc-alpha/2014-06/msg00949.html>, I do not
change the regular expressions used; even where the present
expressions seem more general, I believe they are in fact specific to
the chosen sysdeps directory, because any port that matches the
expression but not the sysdeps directory does not currently exist, and
so would use different symbol versions if added in future (and an
intended goal of these changes is to eliminate the first column in
shlib-versions completely rather than having two different mechanisms
in use for system-specific configuration).
Tested on x86_64 that this does not change the installed shared
libraries. (x86_64 of course does not provide much test coverage for
this patch - what should be architecture-specific contents in
shlib-versions for x86_64 is currently abi-*-ld-soname Makefile

those can move back to shlib-versions.)

[BZ #17354] tile: Fix up corner cases with signed relocations
Some types of relocations technically need to be signed rather than
unsigned: in particular ones that are used with moveli or movei,
or for jump and branch. This is almost never a problem. Jump and
branch opcodes are pretty much uniformly resolved by the static linker
(unless you omit -fpic for a shared library, which is not recommended).
The moveli and movei opcodes that need to be sign-extended generally
are for positive displacements, like the construction of the address of
main() from _start(). However, tst-pie1 ends up with main below _start
(in a different module) and the test failed due to signedness issues in
relocation handling.
This commit treats the value as signed when shifting (to preserve the
high bit) and also sign-extends the value generated from the updated
bundle when comparing with the desired bundle, which we do to make sure
no overflow occurred. As a result, the tst-pie1 test now passes.

i386 TLS_INIT_TP might produce bogus asm changing stack pointer [BZ #17319]
TLS_INIT_TP in sysdeps/i386/nptl/tls.h uses some hand written asm to
generate a set_thread_area that might result in exchanging ebx and esp
around the syscall causing introspection tools like valgrind to loose
track of the user stack. Just use INTERNAL_SYSCALL which makes sure
esp isn't changed arbitrarily.
Before the patch the code would generate:
mov $0xf3,%eax
movl $0xfffff,0x8(%esp)
movl $0x51,0xc(%esp)
xchg %esp,%ebx
int $0x80
xchg %esp,%ebx
Using INTERNAL_SYSCALL instead will generate:
movl $0xfffff,0x8(%esp)
movl $0x51,0xc(%esp)
xchg %ecx,%ebx
mov $0xf3,%eax
int $0x80
xchg %ecx,%ebx
Thanks to Florian Weimer for analysing why the original code generated
the bogus esp usage:
_segdescr.desc happens to be at the top of the stack, so its address
is in %esp. The asm statement says that %3 is an input, so its value
will not change, and GCC can use %esp as the input register for the
expression &_segdescr.desc. But the constraints do not fully describe
the asm statement because the %3 register is actually modified, albeit
only temporarily.

Fix powerpc32 __get_clockfreq for non-power4 (bug 17263).
In my powerpc32 testing I've observed misc/test-gettimebasefreq
failing.
This is a glibc build (soft-float, though that's not relevant here)
without any --with-cpu and without any special configuration of the
default CPU for GCC either. In particular, it's one not using
sysdeps/powerpc/powerpc32/power4/hp-timing.h (although in fact the
processor I'm using for testing is POWER4-based), so hp_timing_t is
32-bit not 64-bit. But the VDSO call being used by
INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK is generating a 64-bit result
(high part in r3, low part in r4). The code extracting that result,
however, expects a result of the type hp_timing_t as passed to
INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK, meaning that only r3 (= 0) is
used and the value in r4 is ignored. This patch fixes this by always
using uint64_t as the type in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK -
reflecting the actual ABI (unconditional in the kernel) of that VDSO
call. This is the minimal change for this issue - no check for
overflow, no change of the type of the timebase_freq variable or the
return type of __get_clockfreq to something other than hp_timing_t
(such a change would simply move the implicit conversions to the over
callers of that function), no change to hp_timing_t itself.
Tested for powerpc32 soft float.

Disable x87 inline functions for x86_64 and SSE [BZ #17262]

commit

Disable x87 inline functions for SSE2 math
When i386 and x86-64 mathinline.h was merged into a single mathinline.h,
"gcc -m32" enables x87 inline functions on x86-64 even when -mfpmath=sse
and SSE2 is enabled. It is a regression on x86-64. We should check
__SSE2_MATH__ instead of __x86_64__ when disabling x87 inline functions.
gcc-3.2 is unable to correctly compile x86_64 routines for llrint
since it gets redefined. This is because gcc 3.2 does not set
__SSE2_MATH__ for x86_64, thus exposing the duplicate definition.
The correct fix ought to be to check for both __SSE2_MATH__ and
__x86_64__ and enable those bits only when neither are defined.
Tested fix with the reproducer for
409e00bd69b8d8dd74d7327085351d26769ea6fc as well as with gcc-3.2.

Replace cpuid asm statement with __cpuid_count
The compiler doesn't know that the cpuid asm statement in intel_check_word
will trash RBX. We are lucky that it doesn't cause any problems since
RBX is also used by compiler for other purposes so that RBX is saved and
restored. This patch replaces it with __cpuid_count.

detect broken linker handling of __ehdr_start
Older versions of ld on ia64 support __ehdr_start, but generate relocs
when they shouldn't. This causes the ld.so to not run because it tries
to resolve the __ehdr_start symbol (but it's not exported).

Fix powerpc-nofpu __fe_enabled_env and __fe_nonieee_env (bug 17261).
On powerpc, floating-point environment macros are defined as pointers
to constants in the library that contain the bit-patterns of the
desired environment, instead of being magic constants cast to pointer
type.
For soft-float, the bit-patterns used for fenv_t are not laid out the
same as for hard-float. (e500 has a third layout used; that's not an
ABI issue because these values are only meaningful within a single
process, all of whose glibc libraries must come from the same build of
glibc.) While the __fe_dfl_env value for soft-float was appropriate
for the soft-float fenv_t representation, the other two constants had
the same bit-patterns as for hard-float. Those bit patterns had the
effect of having exceptions already raised, causing
math/test-fenv-return to fail; this patch fixes the patterns used.
(__fe_nonieee_env also had exceptions unmasked, though they should be
masked to match hard-float semantics. Since there is no separate
non-IEEE mode for soft-float, it's most appropriate for
__fe_nonieee_env to be the same as __fe_dfl_env; this patch makes it
an alias.)
Tested for powerpc-nofpu.

* sysdeps/powerpc/nofpu/fenv_const.c (__fe_enabled_env): Change
value to 0.

This test should be more robust about setting up its lang dirs.
I had two completely different systems (ia64 & x86_64) get wedged

files missing. This probably wasn't a big deal until the recent
commit which made checking of the locale dirs more robust (for

This patch adds new function libc_feholdsetround_noex_aarch64_ctx, enabling
further optimization. libc_feholdsetround_aarch64_ctx now only needs to
read the FPCR in the typical case, avoiding a redundant FPSR read.
Performance results show a good improvement (5-10% on sin()) on cores with
expensive FPCR/FPSR instructions.
