dnl This file is free software; the Free Software Foundation
dnl gives unlimited permission to copy and/or distribute it,
dnl with or without modifications, as long as this notice is preserved.
dnl From Bruno Haible and Sam Steingold.
dnl Sets the HOST_CPU variable to the canonical name of the CPU.
dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
dnl C language ABI (application binary interface).
dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
dnl config.h.
dnl
dnl This canonical name can be used to select a particular assembly language
dnl source file that will interoperate with C code on the given host.
dnl
dnl For example:
dnl * 'i386' and 'sparc' are different canonical names, because code for i386
dnl will not run on SPARC CPUs and vice versa. They have different
dnl instruction sets.
dnl * 'sparc' and 'sparc64' are different canonical names, because code for
dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
dnl mode, but not both.
dnl * 'mips' and 'mipsn32' are different canonical names, because they use
dnl different argument passing and return conventions for C functions, and
dnl although the instruction set of 'mips' is a large subset of the
dnl instruction set of 'mipsn32'.
dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
dnl different sizes for the C types like 'int' and 'void *', and although
dnl the instruction sets of 'mipsn32' and 'mips64' are the same.
dnl * The same canonical name is used for different endiannesses. You can
dnl determine the endianness through preprocessor symbols:
dnl - 'arm': test __ARMEL__.
dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
dnl - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
dnl - Instructions that do not exist on all of these CPUs (cmpxchg,
dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
dnl assembly language source files use such instructions, you will
dnl need to make the distinction.
dnl - Speed of execution of the common instruction set is reasonable across
dnl the entire family of CPUs. If you have assembly language source files
dnl that are optimized for particular CPU types (like GNU gmp has), you
dnl will need to make the distinction.

dnl From Bruno Haible.
dnl Inspired by
dnl https://github.com/linux-test-project/ltp/blob/master/testcases/open_posix_testsuite/conformance/interfaces/pthread_rwlock_rdlock/2-2.c
dnl by Intel Corporation.
dnl Test whether in a situation where
dnl - an rwlock is taken by a reader and has a writer waiting,
dnl - an additional reader requests the lock,
dnl - the waiting writer and the requesting reader threads have the same
dnl priority,
dnl the requesting reader thread gets blocked, so that at some point the
dnl waiting writer can acquire the lock.
dnl Without such a guarantee, when there a N readers and each of the readers
dnl spends more than 1/Nth of the time with the lock held, there is a high
dnl probability that the waiting writer will not get the lock in a given finite
dnl time, a phenomenon called "writer starvation".
dnl Without such a guarantee, applications have a hard time avoiding writer
dnl starvation.
dnl
dnl POSIX:2017 makes this requirement only for implementations that support TPS
dnl (Thread Priority Scheduling) and only for the scheduling policies SCHED_FIFO
dnl and SCHED_RR, see
dnl http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_rwlock_rdlock.html
dnl but this test verifies the guarantee regardless of TPS and regardless of
dnl scheduling policy.
dnl Glibc currently does not provide this guarantee, see
