Here is a reworked commit from Max Filippov:
https://github.com/espressif/newlib-esp32/commit/3fc2b645bb708421962e68366aa8efbdce93d7e3
Max, I dropped some documentation changes, please review and tell if
you are ok with this.
And I dropped all changes for libm from your original commit because
they aren't used. Except disabling __ieee754_sqrtf implementation from
being compiled into libm (because it exists in libgcc). But I just gave
this function __attribute__((weak))
Also, added libgloss implementation for xtensa (for chips
esp32/esp32s3)
Please consider to apply.
Alexey Lapshin (6):
newlib: add system headers from include/$(sys_dir)/*/*.h

libm: add attribute weak for __ieee754_sqrtf

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to
$top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" :
"$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure,
because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+\`configure' configures newlib 1.19.0 to adapt to many kinds of
systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful
variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included
packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or
\`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in
PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in
EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can
specify
+an installation prefix other than \`$ac_default_prefix' using \`--
prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+
+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to
$top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" :
"$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure,
because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+\`configure' configures newlib 1.19.0 to adapt to many kinds of
systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful
variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included
packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or
\`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in
PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in
EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can
specify
+an installation prefix other than \`$ac_default_prefix' using \`--
prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to
$top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" :
"$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure,
because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a

+\`configure' configures newlib 1.19.0 to adapt to many kinds of
systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful
variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included
packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or
\`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in
PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in
EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can
specify
+an installation prefix other than \`$ac_default_prefix' using \`--
prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data

+/* Windowed ABI:
+
+ This implementation relies heavily on the Xtensa register window
+ mechanism. Setjmp flushes all the windows except its own to the
+ stack and then copies registers from the save areas on the stack
+ into the jmp_buf structure, along with the return address of the
call
+ to setjmp. Longjmp invalidates all the windows except its own, and
+ then sets things up so that it will return to the right place,
+ using a window underflow to automatically restore the registers.
+
+ Note that it would probably be sufficient to only copy the
+ registers from setjmp's caller into jmp_buf. However, we also copy
+ the save area located at the stack pointer of setjmp's caller.
+ This save area will typically remain intact until the longjmp call.
+ The one exception is when there is an intervening alloca in
+ setjmp's caller. This is certainly an unusual situation and is
+ likely to cause problems in any case (the storage allocated on the
+ stack cannot be safely accessed following the longjmp). As bad as
+ it is, on most systems this situation would not necessarily lead to
+ a catastrophic failure. If we did not preserve the extra save area
+ on Xtensa, however, it would. When setjmp's caller returns after a
+ longjmp, there will be a window underflow; an invalid return
+ address or stack pointer in the save area will almost certainly
+ lead to a crash. Keeping a copy of the extra save area in the
+ jmp_buf avoids this with only a small additional cost. If setjmp
+ and longjmp are ever time-critical, this could be removed.
+
+
+ Call0 ABI:
+
+ Much like other ABIs, this version just saves the necessary
registers
+ to the stack and restores them later. Much less needs to be done.

+@chapter Functions for Xtensa Processors
+
+This chapter describes machine-dependent functions that are included
+in the C library when it is built for Xtensa processors.
+
+@menu
+* setjmp:: Save stack environment
+* longjmp:: Non-local goto
+@end menu
+
+@page
+@node setjmp
+@section @code{setjmp}---save stack environment
+@findex setjmp
+@strong{Synopsis}
+@example
+#include <setjmp.h>
+int setjmp(jmp_buf env);
+
+@end example
+@strong{Description}@*
+@code{setjmp} and @code{longjmp} are useful for dealing with errors
+and interrupts encountered in a low-level subroutine of a program.
+@code{setjmp} saves the stack context/environment in @code{env} for
+later use by @code{longjmp}. The stack context will be invalidated if
+the function which called @code{setjmp} returns.
+
+@*
+@strong{Returns}@*
+@code{setjmp} returns 0 if returning directly, and non-zero when
+returning from @code{longjmp} using the saved context.
+
+@*
+@strong{Portability}@*
+@code{setjmp} is ANSI C and POSIX.1.
+
+setjmp requires no supporting OS subroutines.

+
+@end example
+@strong{Description}@*
+@code{longjmp} and @code{setjmp} are useful for dealing with errors
+and interrupts encountered in a low-level subroutine of a program.
+@code{longjmp} restores the environment saved by the last call of
+@code{setjmp} with the corresponding @code{env} argument. After
+@code{longjmp} is completed, program execution continues as if the
+corresponding call of @code{setjmp} had just returned the value
+@code{val}. @code{longjmp} cannot cause 0 to be returned. If
+@code{longjmp} is invoked with a second argument of 0, 1 will be
+returned instead.
+
+@*
+@strong{Returns}@*
+This function never returns.
+
+@*
+@strong{Portability}@*
+@code{longjmp} is ANSI C and POSIX.1.
+
+longjmp requires no supporting OS subroutines.

+VAR=VALUE. See below for descriptions of some of the useful
variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included
packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or
