TS 18661-1 defines a type femode_t to represent the set of dynamic
floating-point control modes (such as the rounding mode and trap
enablement modes), and functions fegetmode and fesetmode to manipulate
those modes (without affecting other state such as the raised
exception flags) and a corresponding macro FE_DFL_MODE.
This patch series implements those interfaces for glibc. This first
patch adds the architecture-independent pieces, the x86 and x86_64
implementations, and the <bits/fenv.h> and ABI baseline updates for
all architectures so glibc keeps building and passing the ABI tests on
all architectures. Subsequent patches add the fegetmode and fesetmode
implementations for other architectures.
femode_t is generally an integer type - the same type as fenv_t, or as
the single element of fenv_t where fenv_t is a structure containing a
single integer (or the single relevant element, where it has elements
for both status and control registers) - except where architecture
properties or consistency with the fenv_t implementation indicate
otherwise. FE_DFL_MODE follows FE_DFL_ENV in whether it's a magic
pointer value (-1 cast to const femode_t *), a value that can be
distinguished from valid pointers by its high bits but otherwise
contains a representation of the desired register contents, or a
pointer to a constant variable (the powerpc case; __fe_dfl_mode is
added as an exported constant object, an alias to __fe_dfl_env).
Note that where architectures (that share a register between control
and status bits) gain definitions of new floating-point control or
status bits in future, the implementations of fesetmode for those
architectures may need updating (depending on whether the new bits are
control or status bits and what the implementation does with
previously unknown bits), just like existing implementations of
<fenv.h> functions that take care not to touch reserved bits may need
updating when the set of reserved bits changes. (As any new bits are
outside the scope of ISO C, that's just a quality-of-implementation
issue for supporting them, not a conformance issue.)
As with fenv_t, femode_t should properly include any software DFP
rounding mode (and for both fenv_t and femode_t I'd consider that
fragment of DFP support appropriate for inclusion in glibc even in the
absence of the rest of libdfp; hardware DFP rounding modes should
already be included if the definitions of which bits are status /
control bits are correct).
Tested for x86_64, x86, mips64 (hard float, and soft float to test the
fallback version), arm (hard float) and powerpc (hard float, soft
float and e500). Other architecture versions are untested.

The patched change fixes a regression for executables compiled with the
-p option and linked with gcrt1.o. The executables crash on startup.
This regression was introduced in 2.22 and was noticed in the gcc testsuite.

The attached patch fixes dladdr on hppa.
Instead of using the generic version of _dl_lookup_address, we use an
implementation more or less modeled after __canonicalize_funcptr_for_compare()
in gcc. The function pointer is analyzed and if it points to the
trampoline used to call _dl_runtime_resolve just before the global
offset table, then we call _dl_fixup to resolve the function pointer.
Then, we return the instruction pointer from the first word of the
descriptor.
The change fixes the testcase provided in [BZ #19415] and the Debian
nss package now builds successfully.

[BZ #19270]
The attached patch fixes BZ #19270 and the Debian gmt package now builds
successfully. Aside from the comment, the define of __NO_LONG_DOUBLE_MATH
is similar to that in the generic version of glibc.
Build tested on hppa-unknown-linux-gnu with no observed regressions.

Various math_private.h headers are guarded by "#ifndef
_MATH_PRIVATE_H", but never define the macro. Nothing else defines
the macro either (the generic math_private.h that they include defines
a different macro, _MATH_PRIVATE_H_), so those guards are ineffective.
With the recent inclusion of s_sin.c in s_sincos.c, this breaks the
build for MIPS, since the build of s_sincos.c ends up including
<math_private.h> twice and the MIPS version defines inline functions
such as libc_feholdexcept_mips, without a separate fenv_private.h
header with its own guards such as some architectures have.
This patch fixes all the problem headers to use architecture-specific
guard macro names, and to define those macros in the headers they
guard, just as some architectures already do.
Tested for x86 (testsuite, and that installed shared libraries are
unchanged by the patch), and for mips64 (that it fixes the build).

It was noted in
<https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the
bits/*.h naming scheme should only be used for installed headers.
This patch renames bits/linkmap.h to plain linkmap.h to follow that
convention.
Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).

The startup code was not using PIC friendly references leading to TEXTRELs
in every PIE ELF.
|
|
|
|
|
|
|
| |
This brings hppa inline with all the other arches and main code where we
require TLS support everywhere. That means dropping the defines USE_TLS
and USE___THREAD, and dropping the binutils check (since we already have
a version requirement that is new enough).
|
|
|
|
|
|
|
| |
Commit 2a6ad8142d14c998e6c5eb51418aac1f598b621e updated the headers and
the common dl-symaddr.c, but missed that hppa has its own dedicated source
file for this func. Update that too to fix build errors due to missing
exports of the symbol.
|
|
|
|
|
| |
The conform tests flag the "aligned" symbol used inside the attributes,
so rename it to __aligned__ like other headers.

The semi-recent SYSCALL_CANCEL inclusion broke hppa due to the sysdep.h
headers not including the unix/sysdep.h headers. Rework the includes so
we match the other ports:
* hppa/sysdep.h:
- Do not include sys/syscall.h as the unix sysdep.h headers do it.
- Do not include config.h as libc-symbols.h does it, and it has no
#ifdef multiple-include protection, and it breaks when some files
do things like #undef __OPTIMIZE__.
* sysdeps/unix/sysv/linux/hppa/sysdep-cancel.h:
- Drop the generic/sysdep.h as the unix sysdep.h headers include it.
* sysdeps/unix/sysv/linux/hppa/sysdep.h:
- Change to the unix & core hppa sysdep header stacks.
- Undef a few defines that the core headers already set up for us.

This symbol is only used by DL_UNMAP which in turn is only used by
_dl_close_worker in dl-close.c, and _dl_close_worker itself is marked
hidden as it is only used by the ldso. That means _dl_unmap should
be marked hidden. Without this, the elf/check-localplt test fails.
|
|
|
|
|
|
|
|
|
|
| |
This symbol is defined in the ldso, and is used both there and libc.so.
There is no hidden symbol for it though which leads to relocations in
the ldso and the elf/check-localplt test failing. Add a hidden def for
rtld to fix all of that.
This function/file is only used by hppa & ia64, so no testing is needed
for other arches.

The function feupdateenv has been fixed to correctly handle FE_DFL_ENV
and FE_NOMASK_ENV.
The fesetexceptflag function has been fixed to correctly handle setting
the new flags instead of just OR-ing the existing flags.
This fixes the test-fenv-return and test-fenvinline failures on hppa.
|
|
|
|
|
|
|
|
|
|
|

The constraints in the inline assembly in feholdexcept and fesetenv
are incorrect. The assembly modifies the buffer pointer, but doesn't
express that in the constraints. The simple fix is to remove the
modification of the buffer pointer which is no longer required by
the existing code, and adjust the one constraint that did express
the modification of bufptr.
The change fixes test-fenv when glibc is compiled with recent gcc.

(1) Fix warnings.
This is a bulk update to fix all the warnings that were causing
build failures with -Werror on hppa.
The most egregious problems are in dl-fptr.c which needs to be
entirely rewritten, thus I've used -Wno-error for that.
(2) Fix conformance errors.
The sysdep.c file had __syscall_error and syscall in one file
which caused conformance issues by including syscall when
__syscall_error was linked to. The fix is obviously to split
the file and use syscall.c to implement syscall.

Concluding the fixes for C90 libm functions calling C99 fe* functions,
this patch fixes the case of feupdateenv by making it a weak alias for
__feupdateenv and making the affected code call __feupdateenv.
Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch). Also tested for ARM
(soft-float) that the math.h linknamespace tests now pass.

Continuing the fixes for C90 libm functions calling C99 fe* functions,
this patch fixes the case of fesetround by making it a weak alias of
__fesetround and making the affected code call __fesetround. An
existing __fesetround function in fenv_libc.h for powerpc is renamed
to __fesetround_inline.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch). Also tested for ARM
(soft-float) that fesetround failures disappear from the linknamespace
test results (feupdateenv remains to be addressed to complete fixing
bug 17748).

Various C90 and UNIX98 libm functions call feraiseexcept, which is not
in those standards. This causes linknamespace test failures - except
on x86 / x86_64, where feraiseexcept is inline (for the relevant
constant arguments) in bits/fenv.h.
This patch fixes this by making those functions call __feraiseexcept
instead. All changes are applied to all architectures rather than
considering the possibility that some might not be needed in some
cases (e.g. x86) as it seems most maintainable to keep architectures
consistent.
Where __feraiseexcept does not exist, it is added, with feraiseexcept
made a weak alias; where it is a strong alias, it is made weak.
libm_hidden_def / libm_hidden_proto are used with __feraiseexcept
(this might in some cases improve code generation for existing calls
to __feraiseexcept in some code on some architectures). Where there
are dummy feraiseexcept macros (on architectures without
floating-point exceptions support, to avoid compile errors from
references to undefined FE_* macros), corresponding dummy
__feraiseexcept macros are added. And on x86, to ensure
__feraiseexcept calls still get inlined, the inline function in
bits/fenv.h is refactored so that most of it can be reused in an
inline __feraiseexcept in a separate include/bits/fenv.h.
Calls are changed in C90/UNIX98 functions, but generally not in
functions missing from those standards. They are also changed in
libc_fe* functions (on the basis that those might be used in any libm
function), and in feupdateenv (on the same basis - may be used, via
default libc_*, in any libm function - of course feupdateenv will need
changing to __feupdateenv in a subsequent patch to make that fully
namespace-clean).
No __feraiseexcept is added corresponding to the feraiseexcept in
powerpc bits/fenvinline.h, because that macro definition is
conditional on !defined __NO_MATH_INLINES, and glibc libm is built
with -D__NO_MATH_INLINES, so changing internal calls to use
__feraiseexcept should make no difference.
Tested for x86_64 (testsuite; the only change in disassembly of
installed shared libraries is a slight code reordering in clog10, of
no apparent significance). Also tested for MIPS, where (in the
configuration tested) it eliminates math.h linknamespace failures for
n32 and n64 (some for o32 remain because of other issues).

patch eliminates its use for _dl_init. Since _dl_init was already
declared with hidden visibility, creating a second hidden alias for it
was completely pointless, so this patch replaces all uses of
_dl_init_internal with plain _dl_init instead of using hidden_proto /
hidden_def (which are only needed when you want a hidden alias for a
non-hidden symbol; it's quite possible there are cases where they are
used but don't need to be because the symbol in question is not part
of the public ABI and is only used within a single library, so using
attributes_hidden instead would suffice).
Tested for x86_64 that installed stripped shared libraries are
unchanged by the patch.

This patch removes the first column (patterns matching configuration
names) from shlib-versions, leaving shlib-versions entry selection
based purely on sysdeps directories.
An implication of this removal is that the default for any non-Linux
ports using NPTL will be the same SONAMEs for NPTL libraries as for
Linux (as those defaults, previously limited to .*-.*-linux.*, are
left in nptl/shlib-versions and nptl_db/shlib-versions).
Special host_os handling in configure.ac that was purely for
shlib-versions is removed. (The host_os setting is still used for
libc-abis - see
<https://sourceware.org/ml/libc-alpha/2014-01/msg00375.html> regarding
that - but no entries there are affected by this change.)
Tested on x86_64 and x86 that the installed shared libraries are
unchanged by this patch.

Merge roland/nptl-hppa to master, update and test for hppa-linux-gnu.
This commit squashes and commits the work done by Roland McGrath on
roland/nptl-hppa to migrate hppa to the new non-addon NPTL. Some
additional tweaks were required for tcb-offsets.sym to work correctly
along with clone.S (unique to hppa).

Various architectures have files such as sysdeps/<arch>/shlib-versions
whose contents are in fact entirely Linux-specific, relating only to
the symbol / shared library versions for the port to Linux on that
architecture, when any future port to a different OS on that
architecture would use the symbol version of the glibc release it goes
in, as standard for new ports.
This patch moves such files under sysdeps/unix/sysv/linux/, merging in
the contents of sysdeps/<arch>/nptl/shlib-versions in the process.
The only bits not moved are those relating to libgcc_s versions, which
don't appear OS-specific in the same way that glibc's symbol versions
so. It deliberately does not change the regular expressions given for
matching configurations in each file; some match only Linux although
not Linux-specific, or match other OSes although Linux-specific. It
is with a view to at least the following further cleanups:
* Move architecture-specific content from the toplevel shlib-versions
and nptl/shlib-versions into sysdeps shlib-versions files, so
eliminating another difference between ex-ports and non-ex-ports
architectures.
* Likewise, for OS-specific content in shlib-versions files.
* At that point, the first field in shlib-versions files (the regular
expression matching a configuration triplet) should be redundant, so
eliminate that field and leave shlib-versions selection working
purely on a sysdeps basis (with limited use of %ifdef in
shlib-versions files when needed) rather than having its own
separate mechanism to select what configuration information is
relevant.
* Move the build of gnu/lib-names.h to a similar mechanism to that
used for gnu/stubs.h (each library build installing a version of the
header specifically for that build), so we can eliminate the
duplication of soname information in the makefiles and get it purely
from shlib-versions files again.
There may be other cleanups possible as well (in particular, I'm not
sure that all cases where the same "Earliest symbol set" information
is repeated for many different libraries actually should need to
repeat it rather than specifying it just once for DEFAULT for the
given configuration, and separately specifying any non-default choices
of soname).
Tested x86_64 that the installed shared libraries are unchanged by
this patch.

The definition of SHARED is tested with #ifdef pretty much everywhere
apart from these few places. The tlsdesc.c code seems to be copy and
pasted to a few architectures and there is one instance in the hppa
startup code.
