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.
This matches what the other GNU toolchain projects have done already.
The generated diff in practice isn't terribly large. This will allow
more use of subdir local.mk includes due to fixes & improvements that
came after the 1.11 release series.
The newlib & libgloss dirs are already generated using autoconf-2.69.
To avoid merging new code and/or accidental regeneration using diff
versions, leverage config/override.m4 to pin to 2.69 exactly. This
matches what gcc/binutils/gdb are already doing.
The README file already says to use autoconf-2.69.
To accomplish this, it's just as simple as adding -I flags to the
top-level config/ dir when running aclocal. This is because the
override.m4 file overrides AC_INIT to first require the specific
autoconf version before calling the real AC_INIT.
- Currently, printf("%La\n", 1e1000L) crashes with segv due to lack
of frexpl() function. With this patch, frexpl() function has been
implemented in libm to solve this issue.

So far the build mechanism in newlib only allowed to either define
machine-specific headers, or headers shared between all machines.
In some cases, architectures are sufficiently alike to share header
files between them, but not with other architectures. A good example
is ix86 vs. x86_64, which share certain traits with each other, but
not with other architectures.
Introduce a new configure variable called "shared_machine_dir". This
dir can then be used for headers shared between architectures.

Subject: [PATCH] nvptx port
This port adds support for Nvidia GPU's, which are primarily used as
offload accelerators in OpenACC and OpenMP.
previous commit 4c90db7bc8 introduced
a compile time error because libm/common/s_infconst.c used the remove
__fmath, __dmath, and __ldmath union types.
Since this is very old, and unused for a very long time, just drop the
file and thus the __infinity constants entirely.
Exception: Cygwin exports __infinity from the beginning. There's a very,
VERY low probability that any existing executable or lib still uses this
constant, but we just keep it in for backward compat, nevertheless.

There is no change if libtool is used.
Some run-time support libraries provided by GCC (e.g. libgomp) use
configure checks to detect certain features, e.g. availability of
thread-local storage. The configure script generates a test program and
tries to compile and link it. It should use target libraries and
startfiles of the build tree if available and not random ones from the
installation prefix for this procedure. The search directories
specified by -B are a bit special, see for_each_path() in gcc.c of the
GCC sources. First a search is performed on all search paths with the
multilib directory appended (if desired), then a second search is
performed on demand with the base directory only. For each multilib
there is a "newlib" subdirectory. This directory is specified by a -B
option for the support libraries. In order to find the newlib artifacts
(ctr0.o, libc.a, libg.a and libm.a) they must be located in a proper
multilib subdirectory withing the build directory.

Ensure the Python Lex/Yacc (PLY) cache used by makedocbook is initialized
before it is used by parallelizable rules to make the DocBook XML, as it
appears that these can collide in cache generation, leading to errors.

Currently, the newlib version information needs to be updated in two places:
- newlib/acinclude.m4
- newlib/libc/include/sys/features.h
The goal of this patch is to:
- supply a single location for defining the newlib version
information: newlib/acinclude.m4
- define __NEWLIB__, __NEWLIB_MINOR__ and __NEWLIB_PATCHLEVEL__
This is in line with what gcc does for its version macros. See:
https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html
This patch moves the definition of the _NEWLIB_VERSION, __NEWLIB__
and __NEWLIB_MINOR__ macros from newlib/libc/include/sys/features.h,
to the newly generated newlib/_newlib_version.h file. Additionally,
the __NEWLIB_PATCHLEVEL__ macro was created, for completeness.
In order to stay backwards compatible, newlib/_newlib_version.h gets
included by newlib/newlib.h and newlib/libc/include/sys/features.h.
Note: This patch does _not_ include the modifications to the following
files, as these should all be generated any way.
