It # sets the PTHREAD_LIBS output variable to the threads library and linker # flags, and the PTHREAD_CFLAGS output variable to any special C compiler # flags that are needed. (The user can also force certain compiler # flags/libs to be tested by setting these environment variables.) # # Also sets PTHREAD_CC and PTHREAD_CXX to any special C compiler that is # needed for multi-threaded programs (defaults to the value of CC # respectively CXX otherwise). (This is necessary on e.g. AIX to use the # special cc_r/CC_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also to link with them as well. For example, you might link with # $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # $PTHREAD_CXX $CXXFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # # If you are only building threaded programs, you may wish to use these # variables in your default LIBS, CFLAGS, and CC: # # LIBS="$PTHREAD_LIBS $LIBS" # CFLAGS="$CFLAGS $PTHREAD_CFLAGS" # CXXFLAGS="$CXXFLAGS $PTHREAD_CFLAGS" # CC="$PTHREAD_CC" # CXX="$PTHREAD_CXX" # # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant # has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to # that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). # # Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the # PTHREAD_PRIO_INHERIT symbol is defined when compiling with # PTHREAD_CFLAGS. # # ACTION-IF-FOUND is a list of shell commands to run if a threads library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments. This macro was based on work # by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help # from M. Frigo), as well as ac_pthread and hb_pthread macros posted by # Alejandro Forero Cuervo to the autoconf macro repository. We are also # grateful for the helpful feedback of numerous users. # # Updated for Autoconf 2.68 by Daniel Richard G. # # LICENSE # # Copyright (c) 2008 Steven G.

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.
