Rename struct _reent::_new::_unused members _nextf and _nmalloc to _reserved_3
and _reserved_4, respectively. Rename struct _reent::_new member _unused to
_reserved_5. Provide them only if _REENT_BACKWARD_BINARY_COMPAT is defined.
Remove unused _N_LISTS define.
Add the --enable-newlib-reent-binary-compat configure option. This option is
disabled by default. If enabled, then unused members in struct _reent are
preserved to maintain the structure layout.
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().
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.
Define the configuration-dependent constant CLEANUP_FILE for use in
cleanup_stdio(). This will reduce duplicate code during the addition
of a dedicated stdio atexit handler in a follow-on patch.
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.
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.
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.
Removed duplicate sglue initializations from __sinit(). These
are already initialized in the _REENT_INIT macro in sys/reent.h.
This simplification enables the reduction of _GLOBAL_REENT
dependency in a follow-on patch.
Removed duplicate stdio initializations from __sinit(). These
are already initialized in the _REENT_INIT macro in sys/reent.h.
This simplification enables the reduction of _GLOBAL_REENT
dependency in a follow-on patch.
../newlib/libc/libc.xml:22242: element refentry: validity error : ID iconv already defined
<refentry id="iconv">
Use a separate namespace for chaper ids, to avoid collision between the
ids for the chapter and function 'iconv', now that iconv documentation
is generated unconditionally.
Unless make is invoked with V=1, have xmlto pass the parameter
'man.output.quietly=1' to xsltproc to suppress "Note: Writing foo.N"
output from the manpages stylesheet.
(This doesn't quite do what it says: The output is not silenced if V has
any value, including 0. You could consider that either a bug or a
feature.)
Simplify rules for creating docbook XML used to create manpages:
Updating the output using move-if-change and then unconditionally
touching the .stamp file doesn't make much sense.
The ndbm.c build broke with:

Remove the pointer indirection through the read-only _global_impure_ptr and
directly use a externally visible _impure_data object of type struct _reent.
This enables the static initialization of global data structures in a follow up
patch. In addition, we get rid of a machine-specific file.
By including sys/_stdint.h, all types from stdint.h are
exposed even if stdint.h isn't pulled in explicitely. Include
<machine/_default_types.h instead. Fix up newlib and Cygwin
files which rely on stdint.h types, too.

This fixes a bug introduced in a previous patch (Commit 44b60f0c:
Make __sdidinit unused). Removed intitialization of __cleanup from
__smakebuf_r(). All callers of __smakebuf_r() call __sinit()
through the_CHECK_INIT macro, thus __cleanup is already
initialized. This fix also allows _cleanup_r() to be made static.
Changed its name to cleanup_stdio() and removed its declaration
from local.h.
Rename __sfmoreglue() in sfmoreglue() and make it static. This function is
only used by __sfp() in the same translation unit.
Remove use of register keyword.
[PATCH] newlib: Only call _fputwc_r if ELIX_LEVEL >= 4
(nano-)vfprintf.c is enabled for ELIX_LEVEL >= 1. When _WIDE_ORIENT
is set, its __sprint_r / __sfputs_r functions unconditionally called
_fputwc_r which is only in ELEX_LEVEL >= 4. With this commit,
the _WIDE support in (nano-)vfprintf.c is disabled for ELEX_LEVEL < 4.
This code has not been updated since 2016, and it looks like it has
rotted quite a bit since. It does not build against the current set
of phoenix sources -- I had to hack both the kernel headers and the
newlib headers up to get it to build, and I still have no idea if it
actually links or runs. It seems like the project itself has moved
away from newlib and to its own C library:
https://phoenix-rtos.com/documentation/libc/README.md
So since there's no interest from the phoenix folks to maintain this,
and it has a significant amount of non-standard code that we try to
keep up-to-date (without actually testing it), just punt it all.
The recent makefile reorganization broke the amdgcn port by creating
duplicate __malloc_lock symbols. This patch fixes the problem by renaming
the malloc_support.c file to mlock.c, thus overriding the default symbol
properly. Actually, I'm not sure how this ever worked?
I've had this lying around for probably a year or two at this point.
It just changes all the instance of "errno" from a common symbol to an
extern. I can't offhand recall where the actual definition is, but it
certainly exists in the generic code.
This was disabled as part of the migration away from the cygnus option
as that implied no-dependencies.
We currently have 1-to-1 updates enabled -- if you touch a .c file,
the corresponding .o file will be rebuilt. But if you touch a header
file, none of the files using that get rebuilt.
Integrate the old libm/test/ subdir into the main build. It hasn't
been used in a long time causing the code to rot a bit. I've fixed
some of those, but it still fails for many ports, so it's disabled
by default. People who want to take a closer look can run:
$ make libm/test/test
To help prevent people from missing running this script, integrate it
into the build via maintainer mode.
Also fix the inverted exit status to make this work correctly -- for
some reason, it exited 1 when it worked, and 0 when it failed.
Replace all of the individual autotool steps with a single autoreconf.
This simplifies the documentation greatly, and in the current system,
only takes ~10 seconds to regenerate everything.
Update the developer documentation to cover all the major components
of the current build system. Hopefully this is a fairly complete road
map to everything. I tried to include everything that I wish I knew
when I started hacking on this :P.
Convert all the libc/ subdir makes into the top-level Makefile. This
allows us to build all of libc from the top Makefile without using any
recursive make calls. This is faster and avoids the funky lib.a logic
where we unpack subdir archives to repack into a single libc.a. The
machine override logic is maintained though by way of Makefile include
ordering, and source file accumulation in libc_a_SOURCES.
There's a few dummy.c files that are no longer necessary since we aren't
doing the lib.a accumulating, so punt them.
The winsup code has been pulling the internal newlib ssp library out,
but that doesn't exist anymore, so change that to pull the objects.
