Cygwin: Remove ccwrap
ccwrap massages the compiler's standard include directories to remove
'/usr/include/w32api', with the intent of allowing it to be overriden by
'--with-windows-headers' (See 4c36016b).

I'm not 100% convinced that this is always working as desired, since in
some places w32api includes are done using <w32api/something.h>, which
will find them via the path /usr/include.

If this does turn out to be needed, this could also be implemented by
constructing the appropriate compiler flags once, rather than on every
compiler invocation.

Torbjörn SVENSSON via Newlib 7ed952000c libc/time: Move internal newlib tz-structs into own header
As discussed in GCC bug 97088
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97088), parameters in
prototypes of library functions should use reserved names, or no name
at all.

This patch moves the internal struct __tzrule_struct to its own
internal header sys/_tz_structs.h.  This is included from newlib's
time code as well as from Cygwin's localtime wrapper.

Work submission instruction comes in two flavors. ENQCMD can be called
both in ring 3 and ring 0 and always uses the contents of a PASID MSR
when shipping the command to the device. ENQCMDS allows a kernel driver
to submit commands on behalf of a user process. The driver supplies the
PASID value in ENQCMDS. There isn't any usage of ENQCMD in the kernel as
of now.
The CPU feature flag is shown as "enqcmd" in /proc/cpuinfo.

Ken Brown 0e29048956 Cygwin: always recognize AF_UNIX sockets as reparse points
If __WITH_AF_UNIX is defined when Cygwin is built, then a named
AF_UNIX socket is represented by a reparse point with a
Cygwin-specific tag and GUID.  Make such files recognizable as reparse
points (but not as sockets) even if __WITH_AF_UNIX is not defined.
That way utilities such as 'ls' and 'rm' still behave reasonably.

This requires two changes:

- Define the GUID __cygwin_socket_guid unconditionally.

- Make check_reparse_point_target return PATH_REP on a reparse point
  of this type if __WITH_AF_UNIX is not defined.

Ken Brown 0b4beaf46f Cygwin: fix handling of known reparse points that are not symlinks
Commit aa467e6e, "Cygwin: add AF_UNIX reparse points to path
handling", changed check_reparse_point_target so that it could return
a positive value on a known reparse point that is not a symlink.  But
some of the code in check_reparse_point that handles this positive
return value was executed unconditionally, when it should have been
executed only for symlinks.

As a result, posixify could be called on a buffer containing garbage,
and check_reparse_point could erroneously return a positive value on a
non-symlink.  This is now fixed so that posixify is only called if the
reparse point is a symlink, and check_reparse_point returns 0 if the
reparse point is not a symlink.

Also fix symlink_info::check to handle this last case, in which
check_reparse_point returns 0 on a known reparse point.

- NtOpenFile in get_file_sd

Fix this by adding the FILE_OPEN_REPARSE_POINT flag to those calls
when the file is a known reparse point.

This patch adds support for Armv8-R AArch64.

Armv8-R AArch64 has no EL3, so we don't set vbar_el3, and adjust the

startup code to support that.

We also add a specs file that uses this alternative startup code which
can be used with Armv8-R AArch64 models.

Ken Brown c1f7c4d1b6 Cygwin: winlean.h: remove most of the extended memory API
This was added as a temporary measure in commit e18f7f99 because it
wasn't yet in the mingw-w64 headers.  With one exception, it is now in
the current release of the headers (version 8.0.0), so we don't need
it in winlean.h.

The exception is that VirtualAlloc2 is declared conditionally in
<w32api/memoryapi.h>, but the compilation of Cygwin requires it to
always be declared, even though it will only be executed on systems
that support it.  So retain the declaration in winlean.h.  And add
"WINAPI" to the declaration, as in memoryapi.h.

Add a check that version >= 8 of the mingw-w64 headers is intalled.

Also revert commit 3d136011, which was a related temporary workaround.

Cygwin: ldd: Also look for not found DLLs when exit status is non-zero
If the process exited with e.g. STATUS_DLL_NOT_FOUND, also process the

(We currently only do this when a STATUS_DLL_NOT_FOUND exception occurs,

This still isn't 100% correct, as it only examines the specified file
for missing DLLs, not recursively on the DLLs it depends upon.

Takashi Yano via Cygwin-patches 232fde0e76 Cygwin: pty: Prevent garbled output for existing non-cygwin apps.
- If pseudo console is disabled, non-cygwin apps do not detect
  console device. In this case, some apps output UTF-8 regardless
  of the locale setting. At least git-for-windows, rust-based apps
  and node.js do that. This patch provides backward compatibility
  as default behaviour by setting console codepage to the charset of
  the locale. Even in the cases above, garbled output is prevented
  with this patch in most cases because mintty uses UTF-8 by default.

  I beleave this is not really a problem in cygwin side but that in
  app side, however, some users complain about garbled output with
  existing apps in MSYS2 (which is based on cygwin) in which pseudo
  console is disabled by default.

Corinna Vinschen 8d0ff0768f Cygwin: drop internal O_NOSYMLINK and O_DIROPEN flags
Both flags are outdated and collide with official flags in
sys/_default_fcntl.h, which may result in weird misbehaviour
of file functions.

O_NOSYMLINK is not used anyway.

O_DIROPEN is used in fhandler_virtual and derived classes.
The collision with O_NOFOLLOW results in spurious EISDIR
errors when, e. g., reading files in the registry.
fhandler_base::open_fs uses O_DIROPEN in the call to
fhandler_base::open, but it's not used in this context
further down the road.

Drop both flags and create an alternative "diropen" bool
flag in fhandler_virtual.

Keith Packard via Newlib 1f8e5847df libm: Fix 'gamma' and 'gammaf' functions. Clean up other gamma code. [v2]
The current gamma, gamma_r, gammaf and gammaf_r functions return
|gamma(x)| instead of ln(|gamma(x)|) due to a change made back in 2002
to the __ieee754_gamma_r implementation. This patch fixes that, making
all of these functions map too their lgamma equivalents.

To fix the underlying bug, the __ieee754_gamma functions have been
changed to return gamma(x), removing the _r variants as those are no
longer necessary. Their names have been changed to __ieee754_tgamma to
avoid potential confusion from users.

Now that the __ieee754_tgamma functions return the correctly signed
value, the tgamma functions have been modified to use them.

libm.a now exposes the following gamma functions:

    ln(|gamma(x)|):

	__ieee754_lgamma_r
	__ieee754_lgammaf_r

	lgamma
	lgamma_r
	gamma
	gamma_r

	lgammaf
	lgammaf_r
	gammaf
	gammaf_r

	lgammal	(on machines where long double is double)

    gamma(x):

	__ieee754_tgamma
	__ieee754_tgammaf
	tgamma
	tgammaf
	tgammal (on machines where long double is double)

Additional aliases for any of the above functions can be added if
necessary; in particular, I'm not sure if we need to include
__ieee754_gamma*_r functions (which would return ln(|(gamma(x)|).
