- 3. I ran 'dbxtool &' and 'shelltool &' from tcsh, and they end up in

- tty setups, but tcsh sets up the tty in cbreak and -echo modes, so
- that it can do line editing. This cannot be fixed because tcsh cannot

+
+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 See <https://en.wikipedia.org/wiki/X86_instruction_listings>.
