Do not declare _Float128 support for powerpc64le -mlong-double-64 (bug 22402).

The powerpc bits/floatn.h declares _Float128 support to be present
when the compiler supports it for powerpc64le.  However, in the case
where -mlong-double-64 is used, __MATH_TG does not actually support
_Float128; it only supports _Float128 in the distinct-long-double
case.

This shows up as a build failure when building glibc mainline with GCC
mainline, given the recently added sanity check in math.h for
configurations supported by __MATH_TG, as the compat code for
-mlong-double-64 fails to build.  However, the bug was logically
present before that change (including in 2.26), just less visible.

This patch fixes the build failure by declaring _Float128 to be
unsupported in that case.  (Of course this can't actually stop users
calling the type-generic macros with _Float128 arguments with
-mlong-double-64, just as they could be called with other unsupported
types on other platforms, but perhaps makes it less likely by making
all the type-specific _Float128 interfaces invisible in that case.)

aarch64: Disable lazy symbol binding of TLSDESC

Always do TLS descriptor initialization at load time during relocation
processing to avoid barriers at every TLS access. In non-dlopened shared
libraries the overhead of tls access vs static global access is > 3x
bigger when lazy initialization is used (_dl_tlsdesc_return_lazy)
compared to bind-now (_dl_tlsdesc_return) so the barriers dominate tls
access performance.

TLSDESC relocs are in DT_JMPREL which are processed at load time using
elf_machine_lazy_rel which is only supposed to do lightweight
initialization using the DT_TLSDESC_PLT trampoline (the trampoline code
jumps to the entry point in DT_TLSDESC_GOT which does the lazy tlsdesc
initialization at runtime).  This patch changes elf_machine_lazy_rel
in aarch64 to do the symbol binding and initialization as if DF_BIND_NOW
was set, so the non-lazy code path of elf/do-rel.h was replicated.

The static linker could be changed to emit TLSDESC relocs in DT_REL*,
which are processed non-lazily, but the goal of this patch is to always
guarantee bind-now semantics, even if the binary was produced with an
old linker, so the barriers can be dropped in tls descriptor functions.

After this change the synchronizing ldar instructions can be dropped
as well as the lazy initialization machinery including the DT_TLSDESC_GOT
setup.

I believe this should be done on all targets, including ones where no
barrier is needed for lazy initialization.  There is very little gain in
optimizing for large number of symbolic tlsdesc relocations which is an
extremely uncommon case.  And currently the tlsdesc entries are only
readonly protected with -z now and some hardennings against writable
JUMPSLOT relocs don't work for TLSDESC so they are a security hazard.

7 years agoRemove _Mlong_double_ etc. macros.
Joseph Myers [Mon, 30 Oct 2017 20:58:51 +0000 (20:58 +0000)]
Remove _Mlong_double_ etc. macros.

math.h has a macro _Mlong_double_ for the type to use when declaring
long double functions, and similar macros for other types.
math/Makefile uses -D_Mlong_double_=double in the case of long double
having the same ABI as double.

This originates with:

Mon Jul  8 13:37:40 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

        * math/math.h (_Mfloat_, _Mlong_double_): New macros, defined iff not
        already defined to float, long double.  Use those macros for _Mdouble_
        defns when including mathcalls.h.
        * math/Makefile [$(long-double-fcts) != yes] (CPPFLAGS): Append
        -D_Mlong_double_=double.

However, math.h stopped declaring long double functions in the case of
long double having the same ABI as double (and thus probably stopped
actually needing the Makefile definition of _Mlong_double_) with:

1998-11-05  Ulrich Drepper  <drepper@cygnus.com>

        * math/math.h: Unconditionally include bits/mathdef.h.  Declare
        long double functions only if __NO_LONG_DOUBLE_MATH is not
        defined.
        * sysdeps/generic/bits/mathdef.h: Define only if __USE_ISOC9X.
        Define __NO_LONG_DOUBLE_MATH.
        * sysdeps/m68k/fpu/bits/mathdef.h: Define only if __USE_ISOC9X.
        * sysdeps/i386/fpu/bits/mathdef.h: Likewise.

The declarations were since restored for compiling user code, but
remain absent when _LIBC is defined, which is sufficient to avoid
problems declaring function aliases of incompatible types.  Thus the
indirection through the _Mlong_double_ macro is not needed (probably
since that 1998 patch), and this patch removes _Mlong_double_ and
associated macros for other types, leaving only the macro _Mdouble_
which is actually used as the type for which a given inclusion of
<bits/mathcalls.h> should declared functions.

Tested for x86_64, and tested with build-many-glibcs.py that installed
stripped shared libraries are unchanged by this patch.

i586: Use conditional branches in strcpy.S [BZ #22353]

i586 strcpy.S used a clever trick with LEA to implement jump table:

/* ECX has the last 2 bits of the address of source - 1.  */
andl $3, %ecx

        call    2f
2:      popl    %edx
/* 0xb is the distance between 2: and 1:.  */
        leal    0xb(%edx,%ecx,8), %ecx

        incl    %esi
    /* ECX == 3 */
L(1):   movl    (%esi), %ecx

This fails if there are instruction length changes before L(1):.  This
patch replaces it with conditional branches:

cmpb $2, %cl
je L(Src2)
ja L(Src3)
cmpb $1, %cl
je L(Src1)

L(Src0):

support, this patch adds M_* constants for such types.  The decimal
expansions used are all the same as used for _Float128; there's no
need to reduce the precision used.  In the case of _Float128x, #error
is used because the constants would need additional precision, but how
much is needed would depend on the actual _Float128x format used, so
it's not possible to add header support simply as part of code that
handles all _FloatN / _FloatNx types similarly.

to a positively phrased question
It's used as it or with the verb ("Ne ran ket", ...)
As such, "Ket" is used in most translations.

languages with 3 or 4 form systems.

Carlos O'Donell [Tue, 17 Oct 2017 08:33:42 +0000 (01:33 -0700)]
localedef: Add --no-warnings/--warnings option

From localedef --help:

Output control:
...
      --no-warnings=<warnings>   Comma-separated list of warnings to disable;
                             supported warnings are: ascii, intcurrsym
...
      --warnings=<warnings>  Comma-separated list of warnings to enable;
                             supported warnings are: ascii, intcurrsym

Locales using SHIFT_JIS and SHIFT_JISX0213 character maps are not ASCII
compatible. In order to build locales using these character maps, and
have localedef exit with a status of 0, we add new option to localedef
to disable or enable specific warnings. The options are --no-warnings
and --warnings, to disable and enable specific warnings respectively.
The options take a comma-separated list of warning names. The warning
names are taken directly from the generated warning.  When a warning
that can be disabled is issued it will print something like this: foo is
not defined [--no-warnings=foo]

For the initial implementation we add two controllable warnings; first
'ascii' which is used by the localedata installation makefile target to
install SHIFT_JIS and SHIFT_JISX0213-using locales without error; second
'intcurrsym' which allows a program to use a non-standard international
currency symbol without triggering a warning.  The 'intcurrsym' is
useful in the future if country codes are added that are not in our
current ISO 4217 list, and the user wants to avoid the warning. Having
at least two warnings to control gives an example for how the changes
can be extended to more warnings if required in the future.

These changes allow ja_JP.SHIFT_JIS and ja_JP.SHIFT_JISX0213 to be
compiled without warnings using --no-warnings=ascii. The
localedata/Makefile $(INSTALL-SUPPORTED-LOCALES) target is adjusted to
automatically add `--no-warnings=ascii` for such charmaps, and likewise
localedata/gen-locale.sh is adjusted with similar logic.

v2: Bring verbose, be_quiet, and all warning control booleans into
record-status.c, and compile this object file to be used by locale,
iconv, and localedef. Any users include record-status.h.
v3: Fix an instance of boolean coercion in set_warning().
