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.
|
|
This will make it easier to merge up as it won't have unique settings.
|
|
We use the common config-ml.in for configure, so switch the makefile
over to the common multilib.am. It's almost exactly the same code,
but there are two differences:
* Common code hooks install-exec-local for install-multi, but newlib
doesn't currently install any executables, so that doesn't fire.
Newlib already has install-data-local that inlined install-multi,
so switch that to the common install-multi.
* Common code doesn't provide a check-multi at all. Keep ours for
now. Some day common code might get it. Or not. Who knows.

The machine configure scripts are all effectively stub scripts that
pass the higher level options to its own makefile. There were only
three doing custom tests. The rest were all effectively the same as
the libc/ configure script.
So instead of recursively running configure in all of these subdirs,
generate their makefiles from the top-level configure. For the few
unique ones, deploy a pattern of including subdir logic via m4:
m4_include([machine/nds32/acinclude.m4])
Some of the generated machine makefiles have a bunch of extra stuff
added to them, but that's because they were inconsistent in their
configure libtool calls. The top-level has it, so it exports some
new vars to the ones that weren't already.
|
|
The sys configure scripts are almost all effectively stub scripts that
pass the higher level options to its own makefile. The phoenix & linux
ones are a bit more complicated with nested subdirs, so those have been
left alone for now. Plus, I don't really have a way of testing them.
|
|
There's no need to have a sys/ subdir just to copy the sys/$arch/crt0.o
up to sys/crt0.o, and then have libc/ copy sys/crt0.o up again. Just
have libc/ refer to sys/$arch/crt0.o directly and drop the intermediate
makefile entirely.
|
|
The sys/{configure,Makefile} files exist to fan out to the specific
sys/$arch/ subdir, and to possibly generate a crt0. We already have
all that same info in the libc/ dir itself, so by moving the recursive
configure and make calls into it, we can cut off some of this logic
entirely and save the overhead.
For arches that don't have a sys subdir, it means they can skip the
logic entirely.
The sys subdir itself is kept for the crt0 logic, for now. We'll try
and clean that up next.

Even its set of checks are very small -- it does 2 preprocessor tests
and sets up 2 makefile conditionals.

A bunch of subdirs want this, so make it available in the common
dir to ease future merges. It isn't used directly in libgloss so
it should be harmless as-is.
|
|
Not sure how this snuck in. It's never been used in libm/, so punt it.

Commit a2bfe7cae61a introduced a change ignoring default ACEs on files
to come up with a valid POSIX ACL, reflecting the Windows ACEs actually
making sense on files.
However, if CREATOR OWNER or CREATOR GROUP ACEs - both only making sense
as default ACEs - are found in the ACL, a value indicating the presence
of default ACEs gets set, even on files. This in turn breaks a
subsequent integrity check and get_posix_access returns EINVAL.
The code path handling default ACEs on directories sets this indicator
anyway, so don't set it just because one of the above SIDs are found.
Fixes: a2bfe7cae61a ("Cygwin: ACLs: ignore *_INHERIT flags in file ACLs")

This makes the makefile logic a bit cleaner so we don't have two
files maintaining lists of sources & objects. Since the logic is
tied to cpu capabilities, past those boolean settings down from
the configure logic to the makefile logic.
This will also make it easier to throw away the configure script
in a follow up commit and just keep the makefile.

The nds32 & spu dirs are using compile tests to look for some
preprocessor defines, but we don't need to compile the code,
just preprocess it. So switch to AC_PREPROC_IFELSE.
The sh dir is using a preprocessor test via grep, but let's
switch it to AC_PREPROC_IFELSE too to be consistent.
This should allow us to drop the uncommon AC_NO_EXECUTABLES call.

When building in parallel, make sure the subdir for the sim files
exist before trying to install into them.
|
|
This was added decades ago, but the commit message lacks any
explanation, and it was unused when it was merged. It's still
unused today. So punt it all.
|
|
Generating these files is very cheap, so let's just do it all the time.
This makes the build logic simpler, and keeps errors for slipping in in
codepaths that are not well tested. Creating these files doesn't mean
they'll be included in the manual implicitly.
For example, some of the nano stdio files break documentation because
they don't have any chew directives in them. But no one noticed since
that code path is rarely enabled. So drop the _i and _float def files.
|

This is already handled by autotools for us automatically. You can
tell as the generated output is exactly the same other than deleting
a few blank lines.
|
|
It's unclear why this was added originally, but assuming it was needed
20 years ago, it shouldn't be explicitly required nowadays. Current
versions of autotools already take care of exporting LDFLAGS to the
Makefile as needed (things are actually getting linked). That's why
the configure diffs show LDFLAGS still here, but shifted to a diff
place in the output list. A few dirs stop exporting LDFLAGS, but
that's because they don't do any linking, only compiling, so it's
correct.
As for the use of $ldflags instead of the standard $LDFLAGS, I can't
really explain that at all. Just use the right name so users don't
have to dig into why their setting isn't respected, and then use a
non-standard name instead. Adjust the testsuite to match.

None of the subdirs actually use the multilib arg, so include the
logic only in the top-level configure.
|
|
The current newlib 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.
|
|
This was needed by ancient versions of automake, but that hasn't been
the case since at least automake-1.5, so punt this unused stub.
|
|
Now that we require a recent version of autoconf, we can rely on this
macro working. This change was already made to libm, but these other
dirs were missed as I didn't notice it being duplicated in 3 places.
|

Now that newlib.hin has been brought up to date and all of its defines
are produced by configure, we can switch it to using autoheader without
manual editing. This relies on a few pieces:
* Moving the header & footer into configure.ac via AH_TOP & AH_BOTTOM.
* Running a post-process step on newlib.h to delete all the defines we
didn't export ourselves. Basically, anything without a _ prefix.
This will leave behind some spurious comments in newlib.h related to
the defines we filtered out, but should be harmless, so it's probably
not worth the effort to construct a more complicated sed expression to
also strip those out.
|
|
The list of iconv to/from defines is hand maintained in newlib.hin.
Lets leverage mkdeps.pl to generate this list automatically from the
list of known encodings. The newlib.hin list is up-to-date, so the
list in iconv.m4 matches the list already generated.
|
|
This was added to configure, but never to the header file. Nothing
uses this currently, so it's not a big deal (as all the dynamic logic
is via automake conditionals), but might as well restore it now to
keep autoheader output in sync.
|
|
This will make it easier to move newlib.h to use autoheader directly.
We only want the newlib version defines in our hand curated version
file, _newlib_version.h, not in the template header, newlib.h, so
using AC_DEFINE doesn't make much sense.
|
|
Sort the symbols lexically like autoheader does. There are no other
changes in here. This will make it easier to sync with autoheader.
|
|
Sync these back from newlib.hin to configure.ac, and touchup some of
the forms to be consistent (like being full sentences). Also use the
AC_DEFINE-vs-AC_DEFINE_UNQUOTED macros correctly. This will make it
easier to re-enable autoheader for managing newlib.hin.
|
|
The acconfig.h header was used to run autoheader and then manually
sync the output into newlib.hin. Based on how the files have fallen
out of sync (with newlib.hin having many more templates), this has
not been run in a long time, and attempts to do so now would break
newlib.hin.
Further, if you try to run autoheader now, it will automatically
replace _newlib_version.hin since it's the first entry in the call
to AC_CONFIG_HEADERS.
So let's throw away acconfig.h entirely. It only had 2 slightly
better comments, and the rest were either worse, missing, or stale.
This has the side benefit of avoiding autoheader warning about the
deprecated use of acconfig.h since newer autoconf only wants macro
calls in configure.ac.
|
|
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.
|
|
Now that we require a recent version of autoconf, we can rely on this
macro working. We shift the call in configure.ac down a little to
help keep the generated diff minimal -- there should be no functional
difference otherwise. This is because the autoconf macros will call
a bunch of standard toolchain macros first, and arguably the current
code is incorrect in how it does its testing.

Unless make is invoked with V=1, have xmlto pass the parameter
'man.output.quietly=1' to xsltproc to suppress "Note: Writing foo.N"

RFC2782 clearly says so yet it's a common misconception to perform the
compression in the violation of the standard. This patch fixes that

In case when the native OS resolver is used (via os_query) the returned
response ID is always 0. It should actually match the ID passed in to
res_send() in the DNS request header. This patch fixes that
|
|
- Make sure the answer buffer is properly cleared so there is no trailing
garbage when the response does not fit entirely in;
- Make sure an internal decomp failure gets reported correctly (w/return code -1);
- Make sure that the buffer is not overrun when filling out the header.

Also, make sure the debug setting propagates to the parser of
the remainder of /etc/resolv.conf

The current output doesn't happen to match what is produced on my
system, so force _iconv_ccs to be sorted like is already done in
the ccsbi.h header.

Some changes were made to aliasesbi.c, but not to this file which
dynamically generates it. Add those fixes to this file too.

As the file comments say, this was a backport of an autoconf-2.60 fix,
and shouldn't matter for >autoconf-2.59 versions. Drop it since we use
and require autoconf-2.69 now.

Currently this is only enabled in the top-level as that's the only
place where it seemed to be used. But the libc/sys/phoenix/ dir
also uses this functionality, but fails to explicitly enable it.
Automake workedaround it, but generated warnings. Move the option
to NEWLIB_CONFIGURE so all dirs get it automatically iff they end
up using the option. If they don't use the option, there's no
difference to the generated code.
|
|
Since AM_INIT_AUTOMAKE calls AC_PROG_AWK, and some configure.ac
scripts call it too, we end up testing for awk multiple times. If
we change NEWLIB_CONFIGURE to require the macro instead, then it
makes sure it's always expanded, but only once.
While we're here, do the same thing with AC_PROG_INSTALL since it
is also called by AM_INIT_AUTOMAKE, although it doesn't currently
result in duplicate configure checks.
