Add strftime format checking support for C2x %OB and %Ob (bug 82752). · 843f104d

C2x adds strftime %OB and %Ob formats, for alternative forms of month
names (for mainly Slavic languages where a month name on its own is
declined differently from a month name together with a date within
that month).  This patch adds corresponding format checking support.
(glibc support for these formats was added in glibc 2.27.)

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

Mark C2x built-in functions as such. · 0fa00483

Various built-in functions that GCC has as extensions are now standard
functions in C2x.  This patch adds DEF_C2X_BUILTIN and uses it to mark
them as such.  Some of the so-marked functions were previously
DEF_EXT_LIB_BUILTIN, while some DFP ones were DEF_GCC_BUILTIN
(i.e. __builtin_* only); both sets become DEF_C2X_BUILTIN.  This in
turn requires flag_isoc2x to be defined in various front ends using
builtins.def.

As the semantics of the built-in functions should already be tested,
the tests added only verify that they are declared in C2x mode but not
in C11 mode.  The test of DFP built-in functions being declared for
C2x goes in gcc.dg/dfp/, as while such built-in functions currently
don't depend on whether DFP is supported, that looks like a bug to me
(see bug 91985), so it seems best for the tests not to depend on
exactly how that bug might be fixed.

Bootstrapped with no regressions on x86_64-pc-linux-gnu.

gcc:
	* builtins.def (DEF_C2X_BUILTIN): New macro.
	(exp10, exp10f, exp10l, fabsd32, fabsd64, fabsd128, nand32)
	(nand64, nand128, roundeven, roundevenf, roundevenl, strdup)

Build filesystem library with large file support · 2fc11587

Enable AC_SYS_LARGEFILE to set the macros needed for large file APIs to
be used by default. We do not want to define those macros in the
public headers that users include. The values of the macros are copied
to a separate file that is only included by the filesystem sources
during the build, and then the macros in <bits/c++config.h> are renamed
so that they don't have any effect in user code including our headers.

Also use larger type for result of filesystem::file_size to avoid
truncation of large values on 32-bit systems (PR 91947).
