Corinna Vinschen 0597c84b9b Cygwin: revamp TLS offsets computation
- convert gentls_offsets to a shell script, only running the target
  compiler and gawk.

- Simplify cygtls.h.  The new gentls_offsets script only requires two
  lines with the "public:" keyword as markers.  The comments are not
  used anymore, the output is a preprocesses file without comments.
  Align Makefile rules accordingly.

- Rather than generating perl variables and C #defines, just generate
  .ecu statements and .include the TLS offsets file right from the
  generated assembler file sigfe.s.  It's the only place we really
  need (some of) the offsets.

- Drop the target-specific name of the TLS offsets file and generate
  it on the fly in the build dir.  Fix configure and Makefile rules
  accordingly.

Corinna Vinschen c0d5bb262d Cygwin: configure: Define default valus for target specific variables
Define default values for DLL_ENTRY, DIN_FILE, and TLSOFFSETS_H
and drop them from the x86_64-specific branch.  Keep the mechanism
intact to allow other target CPUs if there ever will be.

Corinna Vinschen d4fa3b4abb Cygwin: config.h: stop including auto-generated tlsoffsets.h file
This was a hack to begin with.  Clean this mess up:

- Move definition of CYGTLS_PADSIZE to cygwin/config.h and drop
  local cygtls_padsize.h
- Rename CYGTLS_PADSIZE to __CYGTLS_PADSIZE__ to keep namespace
  clean.  Redefine as macro, rather than as const.
- Move struct _reent first in struct _cygtls to allow using
  __CYGTLS_PADSIZE__ as offset in __getreent().

Matt Joyce 0a862d1319 Remove __sglue member for one configuration

Matt Joyce 8b96542ed1 Add global __sglue object for all configurations
Added a new global __sglue object for all configurations.
Decouples the global file object list from the _GLOBAL_REENT
structure by using this new object instead of the __sglue member
of _GLOBAL_REENT in __sfp() and _fwalk_sglue().

Sebastian Huber 3941c8a88a stdio: Replace _fwalk_reent() with _fwalk_sglue()
Replaced _fwalk_reent() with _fwalk_sglue(). The change adds an
extra __sglue object as a parameter, which will allow the passing
of a global __sglue object separate from the __sglue member of
struct _reent. The global __sglue object will be added in a
follow-on patch.

Matt Joyce a7bdda0503 Move __sglue initializations to __sfp()
Moved last remaining  __sglue initializations from __sinit() to
__sfp(). The move better encapsulates access to __sglue and
facilitates its decoupling from struct _reent in a follow-on patch.

Matt Joyce d83aa402b7 Remove __sinit_locks / __sinit_recursive_mutex
Remove __sinit_lock_acquire() and __sinit_lock_release().  Replace these with
__sfp_lock_acquire() and __sfp_lock_release(), respectively.  This eliminates a
potential deadlock issue between __sinit() and __sfp().  Remove now unused
__sinit_recursive_mutex and __lock___sinit_recursive_mutex.
2022-05-13 12:31:56 +02:00
Matt Joyce e5e36867f8 Add two __sglue initialization macros
Added _REENT_INIT_SGLUE and _REENT_INIT_SGLUE_ZEROED macros
to initialize __sglue member of struct _reent. This allows
further simplification of __sinit() and facilitates the removal
of __sglue as a member of struct _reent for certain configurations
in a follow-on patch.

Corinna Vinschen 5a6de512ab Cygwin: always add sigmask to child info
Even after fork, we might need the parent sigmask without having
access to the real _main_tls. There's a short time at process startup,
when _main_tls points to the system-allocated stack, but wait_sig is
already running. If we can't lock _main_tls, because find_tls can't
find it yet, we now access the parent's sigmask via child_info.
