Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:
sed -ri '

s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:
chmod a+x sysdeps/unix/sysv/linux/riscv/configure

# perhaps from a slightly-different Autoconf version.
git checkout -f \

Continuing the process of building up and using Python infrastructure
for extracting and using values in headers, this patch adds a test
that MAP_* constants from sys/mman.h agree with those in the Linux
kernel headers. (Other sys/mman.h constants could be added to the
test separately.)
This set of constants has grown over time, so the generic code is
enhanced to allow saying extra constants are OK on either side of the
comparison (where the caller sets those parameters based on the Linux
kernel headers version, compared with the version the headers were
last updated from). Although the test is a custom Python file, my
intention is to move in future to a single Python script for such
tests and text files it takes as inputs, once there are enough
examples to provide a guide to the common cases in such tests (I'd
like to end up with most or all such sets of constants copied from
kernel headers having such tests, and likewise for structure layouts
from the kernel).
The Makefile code is essentially the same as for tst-signal-numbers,
but I didn't try to find an object file to depend on to represent the
dependency on the headers used by the test (the conform/ tests don't
try to represent such header dependencies at all, for example).
Tested with build-many-glibcs.py, and also for x86_64 with older
kernel headers.
* scripts/glibcextract.py (compare_macro_consts): Take parameters
to allow extra macros from first or second sources.
* sysdeps/unix/sysv/linux/tst-mman-consts.py: New file.
* sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc]
(tests-special): Add $(objpfx)tst-mman-consts.out.
($(objpfx)tst-mman-consts.out): New makefile target.

This patch converts the tst-signal-numbers test from shell + awk to
Python.
As with gen-as-const, the point is not so much that shell and awk are
problematic for this code, as that it's useful to build up general
infrastructure in Python for use of a range of code involving
extracting values from C headers. This patch moves some code from
gen-as-const.py to a new glibcextract.py, which also gains functions
relating to listing macros, and comparing the values of a set of
macros from compiling two different pieces of code.
It's not just signal numbers that should have such tests; pretty much
any case where glibc copies constants from Linux kernel headers should
have such tests that the values and sets of constants agree except
where differences are known to be OK. Much the same also applies to
structure layouts (although testing those without hardcoding lists of
fields to test will be more complicated).
Given this patch, another test for a set of macros would essentially
be just a call to glibcextract.compare_macro_consts (plus boilerplate
code - and we could move to having separate text files defining such
tests, like the .sym inputs to gen-as-const, so that only a single
Python script is needed for most such tests). Some such tests would
of course need new features, e.g. where the set of macros changes in
new kernel versions (so you need to allow new macro names on the
kernel side if the kernel headers are newer than the version known to
glibc, and extra macros on the glibc side if the kernel headers are
older). tst-syscall-list.sh could become a Python script that uses
common code to generate lists of macros but does other things with its
own custom logic.
There are a few differences from the existing shell + awk test.
Because the new test evaluates constants using the compiler, no
special handling is needed any more for one signal name being defined
to another. Because asm/signal.h now needs to pass through the
compiler, not just the preprocessor, stddef.h is included as well
(given the asm/signal.h issue that it requires an externally provided
definition of size_t). The previous code defined __ASSEMBLER__ with
asm/signal.h; this is removed (__ASSEMBLY__, a different macro,
eliminates the requirement for stddef.h on some but not all
architectures).
Tested for x86_64, and with build-many-glibcs.py.
* scripts/glibcextract.py: New file.
