Corinna Vinschen b5f9b0241a Cygwin: is_unicode_equiv: implement Unicode equivalence class check
is_unicode_equiv compares two UTF-32 values and returns 1 if
both are member of the same Unicode equivalence class, 0 otherwise.

Note that this function only works with precomposed characters
per Unicode normalization form C.  It doesn't handle decomposed
characters, just like its counterpart in glibc.  I.e., equivalence
class comparison using decomposed chars won't work.  Example:

  fnmatch("[=n=]", "ñ") == 0
  fnmatch("[=ñ=]", "n") == 0

but

  fnmatch("[=n=]", "n\x0303") == 1
  fnmatch("[=n\x0303=]", "n") == 1
  fnmatch("[=n\x0303=]", "n\x0303") == 1

Corinna Vinschen 60c25da90d Cygwin: mbrtowi: define replacement for mbrtowc, returning UTF-32 value
Given how UTF-16 isn't capable to hold all Unicode chars in a single
wchar_t, we need a function returning a wint_t value representing
a UTF-32 value for comparison functions.  Fortunately the important
wide character functions like towupper/towlower, isw<class>, iswctype,
etc, already take wint_t values and newlib handles them as UTF-32.

If only we had switched wchar_t to 32 bit way back when... sigh.

Corinna Vinschen 9afd4c0558 Cygwin: chmod: don't drop default ACEs from directory ACLs
commit bc444e5aa4 introduced a call to get_posix_access()
with a NULL pointer for the mode_t parameter because the value
is not needed later on... entirely ignoring the fact that the
mode_t bits are checked for the object being a directory.

In turn, the get_posix_access() call never checked for default
ACEs and returned only the standard ACEs.  Thus, every chmod call
on a directory dropped the default ACEs from its permissions, as
well as the default NULL deny-ACE used to store specific bits.
It got also impossible to set the sgid bit on directories.

Older coreutils created directories with mode bits filtered through
umask.  Newer coreutils creates directories with full permissions,
0777 by default.

This new coreutils behaviour uncovered the fact that default ACEs for
newly created directories were not filtered by umask starting with
commit bc444e5aa4.

Fix it by applying umask on the default ACEs.

Corinna Vinschen 23e49b18ce setlocale: create LC_ALL string when changing locale
This patch is for the sake of gnulib.

gnulib implements some form of a thread-safe setlocale variant
called setlocale_null_r, which is supposed to return the locale
strings in a thread-safe manner.  This only succeeds if the system's
setlocale already handles this thread-safe, otherwise gnulib adds
some locking on its own.

Newlib's setlocale always writes the global string array holding the
LC_ALL value anew on each invocation of setlocale(LC_ALL, NULL).
Since that doesn't allow to call setlocale(LC_ALL, NULL) in a
thread-safe manner, so locking in gnulib is required.

And here's the problem...

The lock is decorated as dllexport when building for Cygwin.  This
collides with the default behaviour of ld to export all symbols.
If it finds one decorated symbol, it will only export this symbol
to the DLL import lib.

Change setlocale so that it writes the global string array
holding the LC_ALL value at the time the locale gets changed.
On setlocale(LC_ALL, NULL), just return the pointer to the
global LC_ALL string array, just as in GLibc.  The burden of
doing so is negligibly for all targets, but adds thread-safety
for gnulib's setlocal_null_r() function, and gnulib can drop
the lock entirely when building for Cygwin.

Victor L. Do Nascimento c6e601de84 libc: arm: Implement setjmp GCC backwards compatibility.
When compiling Newlib for arm targets with GCC 12.1 onward, the
passing of architecture extension information to the assembler is
automatic, making the use of .fpu and .arch_extension directives
in assembly files redundant.

With older versions of GCC, however, these directives must be
hard-coded into the `arm/setjmp.S' file to allow the assembly of
instructions concerning the storage and subsequent reloading of the
floating point registers to/from the jump buffer, respectively.

This patch conditionally adds the `.fpu vfpxd' and `.arch_extension
mve' directives based on compile-time preprocessor macros concerning
GCC version and target architectural features, such that both the
assembly and linking of setjmp.S succeeds for older versions of
Newlib.

Johannes Schindelin 89f930a964 dumper: avoid linker problem when `libbfd` depends on `libsframe`
A recent binutils version introduced `libsframe` and made it a
dependency of `libbfd`. This caused a linker problem in the MSYS2
project, and once Cygwin upgrades to that binutils version it would
cause the same problems there.

Let's preemptively detect the presence of `libsframe` and if detected,
link to it in addition to `libbfd`.

Maciej W. Rozycki 963d6c79ea RISC-V: Fix floating-point environment support for soft float
We don't have floating-point exception or non-default rounding mode
support for the RISC-V soft-float environment, `feraiseexcept' and
`fesetround' do nothing unless the `__riscv_flen' macro has been set.
Therefore following ISO C language requirements[1] only define macros
for soft float that correspond to actually supported floating-point
environment features, removing failures from GCC testing such as:

FAIL: gcc.dg/torture/fp-int-convert-timode-3.c   -O0  execution test
FAIL: gcc.dg/torture/fp-int-convert-timode-4.c   -O0  execution test
