19 'reference to static identifier "f" in extern inline function'. 34 'reference to static identifier "f" in extern inline function'.
20 This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16. 35 This bug was observed with Oracle Developer Studio 12.6
36 (Sun C 5.15 SunOS_sparc 2017/05/30).
37
38 Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
39 on configurations that mistakenly use 'static inline' to implement
40 functions or macros in standard C headers like <ctype.h>. For example,
41 if isdigit is mistakenly implemented via a static inline function,
42 a program containing an extern inline function that calls isdigit
43 may not work since the C standard prohibits extern inline functions
44 from calling static functions (ISO C 99 section 6.7.4.(3).
45 This bug is known to occur on:
46
47 OS X 10.8 and earlier; see:
48 https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
49
50 DragonFly; see
51 http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
21 52
22 Suppress the use of extern inline on Apple's platforms, as Libc at least 53 FreeBSD; see:
23 through Libc-825.26 (2013-04-09) is incompatible with it; see, e.g., 54 https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
24 <http://lists.gnu.org/archive/html/bug-gnulib/2012-12/msg00023.html>. 55
25 Perhaps Apple will fix this some day. */ 56 OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
57 for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
58 Assume DragonFly and FreeBSD will be similar.
59
60 GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
61 inline semantics, unless -fgnu89-inline is used. It defines a macro
62 __GNUC_STDC_INLINE__ to indicate this situation or a macro
63 __GNUC_GNU_INLINE__ to indicate the opposite situation.
64 GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
65 semantics but warns, unless -fgnu89-inline is used:
66 warning: C99 inline functions are not supported; using GNU89
67 warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
68 It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

20 dnl <https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/lib/libc/stdlib/malloc.c.diff?r1=1.100&r2=1.101&f=h>
21 dnl * Solaris, because its malloc() implementation is based on brk(),
22 dnl not mmap(); hence its free() implementation makes no system calls.
23 dnl For other platforms, you can only be sure if they state it in their
24 dnl documentation, or by code inspection of the free() implementation in libc.

7dnl From Bruno Haible and Sam Steingold.
8
9dnl Sets the HOST_CPU variable to the canonical name of the CPU.
10dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
11dnl C language ABI (application binary interface).
12dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
13dnl config.h.
14dnl
15dnl This canonical name can be used to select a particular assembly language
16dnl source file that will interoperate with C code on the given host.
17dnl
18dnl For example:
19dnl * 'i386' and 'sparc' are different canonical names, because code for i386
20dnl will not run on SPARC CPUs and vice versa. They have different
21dnl instruction sets.
22dnl * 'sparc' and 'sparc64' are different canonical names, because code for
23dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
24dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
25dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
26dnl mode, but not both.
27dnl * 'mips' and 'mipsn32' are different canonical names, because they use
28dnl different argument passing and return conventions for C functions, and
29dnl although the instruction set of 'mips' is a large subset of the
30dnl instruction set of 'mipsn32'.
31dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
32dnl different sizes for the C types like 'int' and 'void *', and although
33dnl the instruction sets of 'mipsn32' and 'mips64' are the same.
34dnl * The same canonical name is used for different endiannesses. You can
35dnl determine the endianness through preprocessor symbols:
36dnl - 'arm': test __ARMEL__.
37dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
38dnl - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
39dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
40dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
41dnl - Instructions that do not exist on all of these CPUs (cmpxchg,
42dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
43dnl assembly language source files use such instructions, you will
44dnl need to make the distinction.
45dnl - Speed of execution of the common instruction set is reasonable across
46dnl the entire family of CPUs. If you have assembly language source files
47dnl that are optimized for particular CPU types (like GNU gmp has), you
48dnl will need to make the distinction.

18dnl As a special exception to the GNU General Public License,
19dnl this file may be distributed as part of a program
20dnl that contains a configuration script generated by Autoconf, under
21dnl the same distribution terms as the rest of that program.
22
23dnl This file defines some "once only" variants of standard autoconf macros.
24dnl AC_CHECK_HEADERS_ONCE like AC_CHECK_HEADERS
25dnl AC_CHECK_FUNCS_ONCE like AC_CHECK_FUNCS
26dnl AC_CHECK_DECLS_ONCE like AC_CHECK_DECLS
27dnl AC_REQUIRE([AC_FUNC_STRCOLL]) like AC_FUNC_STRCOLL
28dnl The advantage is that the check for each of the headers/functions/decls
29dnl will be put only once into the 'configure' file. It keeps the size of
30dnl the 'configure' file down, and avoids redundant output when 'configure'
31dnl is run.
32dnl The drawback is that the checks cannot be conditionalized. If you write
33dnl if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
34dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
35dnl empty, and the check will be inserted before the body of the AC_DEFUNed
36dnl function.
37
38dnl The original code implemented AC_CHECK_HEADERS_ONCE and AC_CHECK_FUNCS_ONCE
39dnl in terms of AC_DEFUN and AC_REQUIRE. This implementation uses diversions to
40dnl named sections DEFAULTS and INIT_PREPARE in order to check all requested
41dnl headers at once, thus reducing the size of 'configure'. It is known to work
42dnl with autoconf 2.57..2.62 at least . The size reduction is ca. 9%.
43
44dnl Autoconf version 2.59 plus gnulib is required; this file is not needed
45dnl with Autoconf 2.60 or greater. But note that autoconf's implementation of
46dnl AC_CHECK_DECLS_ONCE expects a comma-separated list of symbols as first
47dnl argument!

7dnl From Bruno Haible.
8dnl Inspired by
9dnl https://github.com/linux-test-project/ltp/blob/master/testcases/open_posix_testsuite/conformance/interfaces/pthread_rwlock_rdlock/2-2.c
10dnl by Intel Corporation.

12dnl Test whether in a situation where
13dnl - an rwlock is taken by a reader and has a writer waiting,
14dnl - an additional reader requests the lock,
15dnl - the waiting writer and the requesting reader threads have the same
16dnl priority,
17dnl the requesting reader thread gets blocked, so that at some point the
18dnl waiting writer can acquire the lock.
19dnl Without such a guarantee, when there a N readers and each of the readers
20dnl spends more than 1/Nth of the time with the lock held, there is a high
21dnl probability that the waiting writer will not get the lock in a given finite
22dnl time, a phenomenon called "writer starvation".
23dnl Without such a guarantee, applications have a hard time avoiding writer
24dnl starvation.
25dnl
26dnl POSIX:2017 makes this requirement only for implementations that support TPS
27dnl (Thread Priority Scheduling) and only for the scheduling policies SCHED_FIFO
28dnl and SCHED_RR, see
29dnl https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_rwlock_rdlock.html
30dnl but this test verifies the guarantee regardless of TPS and regardless of
31dnl scheduling policy.
32dnl Glibc does not provide this guarantee (and never will on Linux), see
33dnl https://sourceware.org/bugzilla/show_bug.cgi?id=13701

11dnl The general structure of the multithreading modules in gnulib is that we
12dnl have three set of modules:
13dnl
14dnl * POSIX API:
15dnl pthread, which combines
16dnl pthread-h
17dnl pthread-thread
18dnl pthread-once
19dnl pthread-mutex
20dnl pthread-rwlock
21dnl pthread-cond
22dnl pthread-tss
23dnl pthread-spin
24dnl sched_yield
25dnl
26dnl * ISO C API:
27dnl threads, which combines
28dnl threads-h
29dnl thrd
30dnl mtx
31dnl cnd
32dnl tss
33dnl
34dnl * Gnulib API, with an implementation that can be chosen at configure
35dnl time through the option --enable-threads=...
36dnl thread
37dnl lock
38dnl cond
39dnl tls
40dnl yield
41dnl
42dnl They are independent, except for the fact that
43dnl - the implementation of the ISO C API may use the POSIX (or some other
44dnl platform dependent) API,
45dnl - the implementation of the Gnulib API may use the POSIX or ISO C or
46dnl some other platform dependent API, depending on the --enable-threads
47dnl option.
