Mike Frysinger 34af195290 newlib: switch to standard AM_PROG_AS
Now that we require a recent automake version, rely on it to provide AS
and CCAS and CCASFLAGS for us.

Mike Frysinger b9346cee1a newlib: switch to standard AC_PROG_CC
Now that we use AC_NO_EXECUTABLES, and we require a recent version of
autoconf, we don't need to define our own copies of these macros.  So
switch to the standard AC_PROG_CC.

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 953ba1e6d1 newlib: simplify nds32 automake checks
This code is a bit more convoluted than it needs to be.  GPR_SOURCES
is never set to anything, and the automake checks use negative logic
to add the SP & DP source files to dedicated variables that are only
expanded once.  Get rid of the unused variable, use normal boolean
logic, and collapse the source settings into a single variable.

Mike Frysinger 6026ef29d8 newlib: move man page generation into top-level build
This allows building the libc & libm pages in parallel, and drops

noise in the change.

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.

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.

Mike Frysinger 67c600b995 libgloss: restore multilib settings in subdir makefiles
Commit 754f8def0d ("libgloss: merge stub
arch configure scripts up a level") had an unintended side-effect: the
MULTI* variables in the Makefiles no longer get rewritten at configure
time in the subdirs.  Only the top-level Makefile still is.  This is
because the configure integration of multilib (both the way libgloss
did it manually and the way AM_ENABLE_MULTILIB does it) only rewrites
"Makefile".

We could try propagating the MULTI* variables from libgloss/Makefile
down via FLAGS_TO_PASS, but this runs into a limitation: the multilib
logic uses this variable to switch from libgloss/ to each multilib
libgloss/, and libgloss uses this variable to enter subdirectories.
The latter we want, but the former ends up overridding the Makefile
environment.  We could side-step that with some GNU Make directives,
but it feels like we're getting a bit too deep down the rabbit hole.

Instead, let's call config-ml.in ourselves for each subdir Makefile
that the top-level configure generates.  This restores the previous
behavior and should be less risky in general.

This logic should be unnecessary when/if we switch libgloss over to
a non-recursive Automake build (since all build+install settings are
in the single libgloss/Makefile), but it'll be a while before we can
land that rework, so let's fix this up now.

Corinna Vinschen 7ae91f3b56 Cygwin: dllfixdbg: don't overwrite input DLL
Change dllfixdbg to keep the input DLL intact and just generate
a new DLL matching the debug file.  Fix Makefile rule accordingly.
The result is, cygwin0.dll is the original DLL created with full
debug sections and stays that way throughout the build process.
Only new-cygwin1.dll will become the stripped DLL matching with
the file containing the debug sections cygwin1.dbg.  This is ok,
because commit ba02fef995 ("Cygwin: Makefile.am: fix DLL build rule")
made new-cygwin1.dll the DLL to be installed.

Corinna Vinschen ba02fef995 Cygwin: Makefile.am: fix DLL build rule
A single Makefile rule creates three files in three steps, the second
and third one never showing up in dependencies.  The next step creating
the link lib only depends on the first of these files.  Even if the
second or third step in the DLL build rule fails, the next make
invocation never picks up on this and just goes ahead creating the
link lib.

Fix this by splitting the DLL build rule into three rules, with
every step on the way depending on the previous rule.  Also fix up
the names, TEST_DLL_NAME just doesn't cut it.

Mike Frysinger 8622002ffc libgloss: move to ../config/multi.m4 for multilib logic
The current libgloss multilib logic is almost exactly the same as the
config/multi.m4, and the differences should be minor, so switch over
to that to delete custom logic on ourside.

The insertions here look larger and that's because none of the scripts
were declaring --enable-multilib explicitly even though they checked the
flag and changed behavior.

Mike Frysinger d5a20f0b70 libgloss: merge epiphany & libnosys & or1k configure scripts up a level
These subdirs have unique configure scripts to do some compiler tests.
The checks should work for all targets, so hoist them up to the top
libgloss dir.  This should allow us to delete these subdir configure
scripts.

It means the top-level gains autoheader support, but that's fine.
It wasn't exporting any defines previously (i.e. -D into CPPFLAGS),
and all of the defines it now exports are only used by code in the
libnosys subdir which was expecting to have a config.h.

Mike Frysinger 4b0e66093c newlib: fix preprocessor checks
Restore the call to AC_NO_EXECUTABLES -- I naively assumed in commit
2e9aa5f56c ("newlib: update preprocessor
configure checks") that checking for a preprocessor would not involve
linking code.  Unfortunately, autoconf will implicitly check that the
compiler "works" before allowing it to be used, and that involves a
link test, and that fails because newlib provides the C library which
is needed to pass a link test.

There is some code in NEWLIB_CONFIGURE specifically to help mitigate
these, but it's not kicking in here for some reason, so let's just add
the AC_NO_EXECUTABLES call back until we can unwind that custom logic.

Additionally, we have to call AC_PROG_CPP explicitly.  This was being
invoked later on, but only in the use_libtool=yes codepath, and that
is almost never enabled.

Mike Frysinger 6a59fc444b newlib: fix cygwin -I path
This code snippet assumed it was only ever run in the top configure
script where srcdir would point to newlib/ which is parallel to the
winsup/ tree.  This is incorrect for all of the subdir configure
scripts leading to bad -I flags in $(CC).  Switch it over to the
new abs_newlib_basedir which should work in all subdirs.

Mike Frysinger fc0bd2eb03 newlib: use abs_newlib_basedir for -I paths
When we had configure scripts in subdirs, the newlib_basedir value
was computed relative to that, and it'd be the same when used in the
Makefile in the same dir.  With many subdir configure scripts removed,
the top-level configure & Makefile can't use the same relative path.
So switch the subdir Makefiles over to abs_newlib_basedir when they
use -I to find source headers.

Do this for all subdirs, even ones with configure scripts and where
newlib_basedir works.  This makes the code consistent, and avoids
surprises if the configure script is ever removed in the future as
part of merging to the higher level.

Some of the subdirs were using -I$(newlib_basedir)/../newlib/ for
some reason.  Collapse those too since newlib_basedir points to the
newlib source tree already.

Mike Frysinger 6444f108d9 newlib: export abs_newlib_basedir for all subdirs
When using the top-level configure script but subdir Makefiles, the
newlib_basedir value gets a bit out of sync: it's relative to where
configure lives, not where the Makefile lives.  Move the abs setting
from the top-level configure script into acinclude.m4 so we can rely
on it being available everywhere.  Although this commit doesn't use
it anywhere, just lays the groundwork.

    newlib: internalize HAVE_INITFINI_ARRAY

    This define is only used by newlib internally, so stop exporting it
    as HAVE_INITFINI_ARRAY since this can conflict with defines packages
    use themselves.

    We don't really need to add _ to HAVE_INIT_FINI too since it isn't
    exported in newlib.h, but might as well be consistent here.

    We can't (easily) add this to newlib_cflags like HAVE_INIT_FINI is
    because this is based on a compile-time test in the top configure,
    not on plain shell code in configure.host.  We'd have to replicate
    the test in every subdir in order to have it passed down.

So when libc/ recursed into machine/, it would stop going deeper as

fails.  Add a quick hack to the top dir to ignore all machine/$arch/

For about half the ports, we don't need a subdir configure script.
They're using the config/default.m[ht] rules, and they aren't doing
any unique configure tests, so they exist just to pass top-level
settings down to create the arch Makefile.  We can just as easily
do that from the top-level Mkaefile directly and skip configure.

Most of the remaining configure scripts could be migrated up to
the top-level too, but that would require care in each subdir.
So let's be lazy and put that off to another day.
