The SSE4.2 implementation is used in the DSO only. The patch also adds
some infrastructure to be used in similar code later one.
|
|
Old binutils don't provide IFUNC and don't generate the section start/end
symbols we expect. At least for now only add the initializer code for
static IFUNC relocations if multi-arch support is requested.
|
|
|
|
I didn't remove an instruction from a previous version in the final
version.
|
|
|
|
Little typo could cause additional characters to be printed.
|
|
Avoids warnings.
|
|
There is some existing practice in other OSes and it's trivial to
implement giving the existing code. Fixes BZ #10221.
|
|
The test to call the indirect function now includes a subtest to
checked whether the symbol is defined. When coming to that point
this is almost always the case. The test for STT_GNU_IFUNC on the
other hand rarely is true. Move it to the front means we don't have
to perform the second test unless really necessary.
|
|
The remaining bytes were not copied correctly.
|

|
Now that static executables can handle IFUNC functions don't exclude
optimization for sched_cpucount for !SHARED.
|
|
Add support for the IRELAIVE relocation and IFUNC in static executables.
|
|
SO far Intel and AMD use exactly the same bits meaning the same
things in CPUID index 1. Simplify the code. Should an architecture
come along which doesn't use the same semantics then it must use a
different index value than COMMON_CPUID_INDEX_1.

Hidden by previous .gitignore content.

|
Similar to the changes which went already in for the other formats,
follow POSIX rules for errno.
|

|
This saves about 1.5kB in the DSO.
|
|
* db-symbols.awk: Use the last field for the symbol name instead
of the 8th one.
|

|
|
After the last addition to the math test suite PPC routines haven't
been adjusted so far.
|

|
|
So far accept4 was only supported on archs using socketcall for x86.
This patch adds support for the remaining archs.

The latest stratcliff extension exposed a bug in the IA-64 memchr which
uses non-speculative loads to prefetch data. Change the code to use
speculative loads with appropriate fixup. Fixes BZ 10162.
|
|
|
|
The ____longjmp_chk functions on x86 and x86-64 were placed in .rodata.str1.1.
|
|
|
|
This definition was meant to be removed before the checkin. It was
used in the development.
|
|
The header had the old name (paccept).
|
|
|
|
|
|
Following the previous changes for x86 and x86-64.

There are two issues with the forced loop exit in the nscd lookup:
1. the estimate of the entry size isn't pessimistic enough for all
databases, resulting potentially is too early exits
2. the combination of 64-bit process and 32-bit nscd would lead to
rejecting valid records in the database.
|
|
The unrelated function __libc_cleanup_routine should not be in
this file. Move it into its own file.
|
|
Unify all three places where we enable async cancellation for
syscalls. Optimize a bit.
|
|
We don't update the RPC sources from the original tarball anymore.
No need to ignore that directory.

This fixes BZ #10159. The stdlib.h definition was out of date.
|
|
The move to nscd-client.h was only needed for some interim version
of the patch. The final version doesn't need it. Undo the change.
|
|
The patch to bound the search in the nscd caches used a wrong exit
condition. Fixed now.
|
|
Needed to allow overwriting architectures init.c in csu and nptl
individually. Fixes BZ #9924.
