Subject: [PATCH 00/14] Add --enable-newlib-reent-thread-local option
Date: Tue, 21 Jun 2022 14:49:17 +0200 [thread overview]
Message-ID: <20220621124931.36450-1-sebastian.huber@embedded-brains.de> (raw)
By default, Newlib uses a huge object of type struct _reent to store
thread-specific data. This object is returned by __getreent() if the
__DYNAMIC_REENT__ Newlib configuration option is defined.
The reentrancy structure contains for example errno and the standard input,
output, and error file streams. This means that if an application only uses
errno it has a dependency on the file stream support even if it does not use
it. This is an issue for lower end targets and applications which need to
qualify the software according to safety standards (for example ECSS-E-ST-40C,
ECSS-Q-ST-80C, IEC 61508, ISO 26262, DO-178, DO-330, DO-333).
If the new _REENT_THREAD_LOCAL configuration option is enabled, then struct
_reent is replaced by dedicated thread-local objects for each struct _reent
member. The thread-local objects are defined in translation units which use
the corresponding object.
Patches 1 to 13 contain no functional changes (hopefully). They just introduce
macros to be able to use struct _reent members or thread-local objects
depending on the new _REENT_THREAD_LOCAL option. Patch 14 adds the new
configuration option.
Matt Joyce (13):
Define _REENT_EMERGENCY(ptr) only once
Add _REENT_ERRNO(ptr)
Add _REENT_STDIN(ptr)
Add _REENT_STDOUT(ptr)
Add _REENT_STDERR(ptr)
Add _REENT_INC(ptr)
Add _REENT_LOCALE(ptr)
Add _REENT_CLEANUP(ptr)
Add _REENT_CVTLEN(ptr)
Add _REENT_CVTBUF(ptr)
Add _REENT_SIG_FUNC(ptr)
Add _REENT_IS_NULL()
Add --enable-newlib-reent-thread-local option
