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.
|
|
Reduced number of global __sf[] declarations from two to one,
simplifying initializations in sys/reent.h.
|
|
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.

Also generate manpages for functions in chapter sys.tex, omitted in
error.

../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.)
|
|
This will generate multiple manpage files as an output, but we don't
know what they will be called, so use a timestamp for build avoidance.
|
|
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 nano malloc build broke with:
Commit 357d7fcc6
In <stdio.h> provide only necessary types
The above commit exposed a latent missing-header bug:
newlib/libc/stdlib/nano-mallocr.c:220:33: error: ‘uintptr_t’ undeclared (first use in this function)

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.

This reverts commit 4232d171a620662aaed650879936eac60aefd9e0.
|

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.

DEJAGNU could not find the function 'newlib_target_compile', because it was defined in another file.

This macro is unused or expands to nothing.
|
|
Removed the unused function _cleanup() from findfp.c.
|
|
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.
|

Remove the _fwalk() implementation to avoid duplicated code with
_fwalk_reent().

[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?
|
|
Consistently use
if !ELIX_LEVEL_1
to enable EL/IX level 2 interfaces.
|
|
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.
|

Rather than define per-object rules in the Makefile, have small files
that define & include the right content. This simplifies the build
rules, and makes understanding the source a little easier (imo) as it
makes all the subdirs behave the same: you have 1 source file and it
produces 1 object. It's also about the same amount of boiler plate,
without having to define custom build rules that can fall out of sync.
We also realign the free & pvalloc definitions: common code puts these
in malloc.o & valloc.o respectively, not in free.o & pvalloc.o objects.
This will also be important as we merge the libc.a build into the top
dir since it relies on a single flat list of objects for overrides.
|
|
Move the multiplex logic out of the build and into source files to
make the build rules a lot simpler.
|
|
The mallopt symbol is defined in tiny-malloc.c, not mallocr.c, but
the Makefile in here tries to compile it out of the latter. This
leads to mallopt never being defined.
The build also creates mallinfo.o & mallopt.o & mallstats.o objects
to override common ones, but the common dir doesn't use these names.
Instead, it places these all in mstats.o.
So move the build define logic to a dedicated file and compile it
directly to make things a bit simpler while fixing the missing func
and aligning objects with the cmomon code.

Some awk implementations such as old versions of mawk do not support the
length() function. Use the return value of the POSIX split() function instead.

This file is a little confusing: it provides all of the mallocr logic,
but is compiled multiple times to produce a unique symbol each time.
For example, building mallocr.c with -DDEFINE_FREER produces freer.o
that only defines _free_r(). This is fine for most symbols, but it's
a little confusing when defining mallocr itself -- we produce a file
with the same symbol name, but we still need -DDEFINE_MALLOCR. In
order to move the logic from the build rules to source files, using
mallocr.c both as a multiplexer and for defining a single symbol is a
bit tricky. It's possible (if we add a lot of redundant preprocessor
checks to mallocr.c, or we add complicated build flags just for this
one files), but it's easier if we simply rename this to a dedicated
file. So let's do that.
We do this as a dedicated commit because the next one will create a
new mallocr.c file and git's automatic diff algorithms can handle
trivial renames, but it can't handle renames+creates in the same
commit.
|
|
Simplify the build system logic a bit by moving the mallocr.c ->
nano-mallocr.c redirection from the Makefile to the source files.
This allows for consistent object name usage regardless of the
configuration options used in case a machine dir wants to define
its own override.

- apply fix from Tom de Vries <vries@gcc.gnu.org>
to have calloc zero out storage for nvptx calloc function
|
|
Since we already set up _LIBC to indicate source files are building
for newlib, we don't need this malloc-specific symbol. Convert it
over to simplify the build a bit.
|
|
This is already called earlier in this file, so no need to do it again.
|
|
Some of these functions are using memcpy & memset from string.h but
not including the header leading to implicit declaration warnings.
|
|
The current targ-include setup runs `cp` every header file it installs,
in serial. This can be a little noticeable on systems, so cleanup the
logic to rely on cp's ability to copy multiple files to a directory in
a single call.
We still need a check for empty directories with no headers (i.e. the
glob doesn't match anything), so add a helper variable to contain that
logic to reduce the boiler plate a little.

Some of these rules were already unnecessary as they were compiling a
single source file into the same named object w/out custom flags, and
Automake handles that for us completely.

dir since it relies on a single flat list of objects for overrides.

Since POSIX cp requires copying a file to a directory without having
to specify the name explicitly, rely on that to avoid calling basename
on every source file.
We can also drop the stub `true` call if the -f test failed. The use
of `if` already takes care of that in POSIX shell.
|
|
This kills off the last configure script under libc/ and folds it
into the top newlib configure script. The a lot of the logic was
already in the top configure script, so move what's left into a
libc/acinclude.m4 file.
