-
-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.

AC_PREREQ([2.60])
-dnl gl_PTHREADLIB
-dnl -------------
-dnl Tests for the libraries needs for using the POSIX threads API.
-dnl Sets the variable LIBPTHREAD to the linker options for use in a Makefile.
-dnl Sets the variable LIBPMULTITHREAD, for programs that really need
-dnl multithread functionality. The difference between LIBPTHREAD and
-dnl LIBPMULTITHREAD is that on platforms supporting weak symbols, typically
-dnl LIBPTHREAD is empty whereas LIBPMULTITHREAD is not.
-dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
-dnl multithread-safe programs.
-dnl Defines the C macro HAVE_PTHREAD_API if (at least parts of) the POSIX
-dnl threads API is available.
+dnl The general structure of the multithreading modules in gnulib is that we
+dnl have three set of modules:
+dnl
+dnl * POSIX API:
+dnl pthread, which combines
+dnl pthread-h
+dnl pthread-thread
+dnl pthread-once
+dnl pthread-mutex
+dnl pthread-rwlock
+dnl pthread-cond
+dnl pthread-tss
+dnl pthread-spin
+dnl sched_yield
+dnl
+dnl * ISO C API:
+dnl threads, which combines
+dnl threads-h
+dnl thrd
+dnl mtx
+dnl cnd
+dnl tss
+dnl
+dnl * Gnulib API, with an implementation that can be chosen at configure
+dnl time through the option --enable-threads=...
+dnl thread
+dnl lock
+dnl cond
+dnl tls
+dnl yield
+dnl
+dnl They are independent, except for the fact that
+dnl - the implementation of the ISO C API may use the POSIX (or some other
+dnl platform dependent) API,
+dnl - the implementation of the Gnulib API may use the POSIX or ISO C or
+dnl some other platform dependent API, depending on the --enable-threads
+dnl option.
+dnl
+dnl This file contains macros for all of these APIs!
-dnl gl_THREADLIB
-dnl ------------
-dnl Tests for a multithreading library to be used.
-dnl If the configure.ac contains a definition of the gl_THREADLIB_DEFAULT_NO
-dnl (it must be placed before the invocation of gl_THREADLIB_EARLY!), then the
-dnl default is 'no', otherwise it is system dependent. In both cases, the user
-dnl can change the choice through the options --enable-threads=choice or
-dnl --disable-threads.
-dnl Defines at most one of the macros USE_ISOC_THREADS, USE_POSIX_THREADS,
-dnl USE_ISOC_AND_POSIX_THREADS, USE_WINDOWS_THREADS.
-dnl The choice --enable-threads=isoc+posix is available only on platforms that
-dnl have both the ISO C and the POSIX threads APIs. It has the effect of using
-dnl the ISO C API for most things and the POSIX API only for creating and
-dnl controlling threads (because there is no equivalent to pthread_atfork in
-dnl the ISO C API).
-dnl Sets the variables LIBTHREAD and LTLIBTHREAD to the linker options for use
-dnl in a Makefile (LIBTHREAD for use without libtool, LTLIBTHREAD for use with
-dnl libtool).
-dnl Sets the variables LIBMULTITHREAD and LTLIBMULTITHREAD similarly, for
-dnl programs that really need multithread functionality. The difference
-dnl between LIBTHREAD and LIBMULTITHREAD is that on platforms supporting weak
-dnl symbols, typically LIBTHREAD is empty whereas LIBMULTITHREAD is not.
-dnl Adds to CPPFLAGS the flag -D_REENTRANT or -D_THREAD_SAFE if needed for
-dnl multithread-safe programs.
-dnl Since support for GNU pth was removed, $LTLIBTHREAD and $LIBTHREAD have the
-dnl same value, and similarly $LTLIBMULTITHREAD and $LIBMULTITHREAD have the
-dnl same value. Only system libraries are needed.
