[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.

Mike Frysinger be9c0561e7 newlib: drop phoenix support
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.

Andrew Stubbs 761ef3b434 amdgcn: Fix build failure
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?

Jeff Law 0c8679e080 Avoid using common symbols in v850 libgloss
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.

Mike Frysinger 958833a0d3 newlib: integrate iconv update to maintainer build
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.

Mike Frysinger 96bc16f6b2 newlib: libc: merge build up a directory
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.

Mike Frysinger b2d4dc167c newlib: xstormy16: move malloc multiplex logic from build to source files
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.

Mike Frysinger 8c383e9ae7 newlib: xstormy16: break up mallocr stubs

Mike Frysinger 5cd957ff66 newlib: xstormy16: fix mallopt definition & mstats handling
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.

Mike Frysinger 4ad6b4d4df newlib: libc: move stdlib multiplex logic from build to source files
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.

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.

Also take the opportunity to clean up the unnecessary header deps in
here.  Automake provides dependency generation for free now.

Mike Frysinger b1b44f777c newlib: rename mallocr.c to _mallocr.c
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.

Mike Frysinger d7b16b0576 newlib: move nano-malloc logic from build to source files
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.

Mike Frysinger dea52d5c1e newlib: convert INTERNAL_NEWLIB to _LIBC
Since we already set up _LIBC to indicate source files are building

Mike Frysinger 28724b2f62 newlib: libc: move stdio multiplex logic from build to source files
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.
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.

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.

Also take the opportunity to clean up the unnecessary header deps in
here.  Automake provides dependency generation for free now.

Mike Frysinger 8343db918f newlib: libc: move configure into top-level
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.

Matt Joyce 44b60f0c4b Make __sdidinit unused
Remove dependency on __sdidinit member of struct _reent to check
object initialization. Like __sdidinit, the __cleanup member of
struct _reent is initialized in the __sinit() function. Checking
initialization against __cleanup serves the same purpose and will
reduce overhead in the __sfp() function in a follow up patch.

Mike Frysinger 416792d59a newlib: libc: delete crt0.o duplication
The crt0.o was handled in a subdir-by-subdir basis: it would be compiled
in one (e.g. libc/sys/$arch/), then copied up one level (libc/sys/), then
copied up another (libc/) before finally being copied & installed in the
top newlib dir.  The libc/sys/ copy was cleaned up, and then the top dir
was changed to copy it directly out of the libc/sys/$arch/ dir.  But the
libc/sys/ copy to libc/ was left behind.  Clean that up now too.

Mike Frysinger 56c65fb8d9 newlib: posix: use local includes for local headers
These headers aren't installed, so use "" includes instead of <> so
we don't search system header paths.  This matches the style used
elsewhere in the tree for these local headers, and makes it work
w/out explicit -I flags (as needed with non-recursive make).

Mike Frysinger c75bb30fc1 newlib: libc: reshuffle include order for the manual

existing chapters and update the comments to explain.

Mike Frysinger 48942fe31a newlib: powerpc: switch to Automake conditionals
Using xxx_LIBADD, xxx_DEPENDENCIES, and EXTRA_xxx_SOURCES is one way of
conditionally including files into a target.  But it's meant more for the
cases where the variables added to LIBADD & DEPENDENCIES are constructed
via substitution (e.g. AC_SUBST) or other dynamic methods.  With Automake
conditionals, then the much simpler form is to conditionally append to
the xxx_SOURCES variable and let Automake sort everything out.

Mike Frysinger 2a83e65fc2 newlib: rtems: drop redundant header install

Mike Frysinger d1591ed4a1 newlib: i386/xstormy16: drop unused -I libm/common flag
These subdirs don't actually use anything from libm.  The common dir
in particular only has 4 header files, and none are included here.

The xstormy16 code has a comment mentioning why this hack is here, but
it refers to code that was removed when its configure script was merged
up a level.

Mike Frysinger 907764ebec newlib/libgloss: drop unused $(CROSS_CFLAGS)

Mike Frysinger df5808b771 newlib: drop support for decstation & sunos systems
These targets don't actually cross-compile -- they try to pull some
objects out of the host's /lib/libc.a, /lib/libm.a, and /lib/crt0.o
directly and merge them into newlib's own libraries.  This is hard
to keep working and impossible to test.  Considering the vintage of
such targets, and gcc dropping them many many years ago, drop them
from newlib too.  This will make cleaning up the build a lot easier.

Mike Frysinger d470ef6463 newlib: phoenix: merge machine/ trampoline up a level
The machine/{configure,Makefile} files exist only to fan out to the
specific machine/$arch/ subdir.  We already have all that same info
in the phoenix/ dir itself, so by moving the recursive configure and
make calls into it, we can cut off this logic entirely and save the
overhead.

Mike Frysinger 16c12761fd newlib: phoenix: drop missing machine subdirs

Mike Frysinger 006da84337 newlib: drop libtool support
This was only ever used for i?86-pc-linux-gnu targets, but that's been
broken for years, and has since been dropped.  So clean this up too.

This also deletes the funky objectlist logic since it only existed for
the libtool libraries.  Since it was the only thing left in the small
Makefile.shared file, we can punt that too.

Mike Frysinger 5a0ab4454b newlib: punt sys/linux support
This was only used by the i?86-pc-linux-gnu target which we've removed,
and even though it's using a "sys/linux/" dir to make it sound like it
only depends on the Linux kernel, it's actually tied to glibc APIs built
on top of Linux.  Since the code relies on internal glibc APIs and has
been broken for some time, punt it all.  If someone wants to bring it
back, they can try and actually keep the Linux-vs-glibc APIs separate.

Mike Frysinger 9b50254377 newlib: move AC_NO_EXECUTABLES logic up to common code
This logic was added to libc & libm to get it working again after some
reworks in the CPP handling, but now that that's settled, let's move
this to the common newlib configure logic.  This will make it easier
to consolidate all the configure calls into the top-level newlib dir.

This does create a lot of noise in the generate scripts, but that's
because of the ordering of the calls, not because of correctness. We
will try to draw that back down in follow up commits as we modernize
the toolchain calls in here.

Mike Frysinger fc2b4ffee0 newlib: libc: move manual into top-level build
This doesn't migrate all the docs, just the libc's manual (pdf/info).
This is to show the basic form of migrating the chew files.

For subdirs that didn't have any docs, I've stripped their settings
for clarity.  If someone wanted to suddenly add docs, they can add
the corresponding Makefile.inc files easily.
2022-02-04 23:57:12 -05:00
Mike Frysinger 44f6310bf9 newlib: libc: include all chapters all the time in the manual
THe stdio subdir is actually required by the documentation.  The
stdio/def is handled dynamically, but libc.texi always expects it
to be included, and fails if it isn't.  So making it required when
building docs is safe.

The xdr subdir is handled dynamically, but it doesn't include any
docs, so the dynamic logic isn't (currently) adding any value.  So
making it required when building docs is safe.

That leaves: iconv, stdio64, posix, and signal subdirs.  The chapters
have a little disclaimer saying they are system-dependent, but even
then, imo having stable manuals regardless of the target is preferable,
and we can add more disclaimer language to these chapters if we want.

This doesn't touch the man page codepaths, just the info/pdf.
