    151           <para>By default, the linker would generate the classic ELF hash
    152           table for shared libraries and dynamically linked executables
    153           because the GNU-style hash table is incompatible with the MIPS o32
    154           ABI. The hash tables are only intended for a dynamic linker to
    155           perform symbol lookup.  On LFS the dynamic linker (provided by the
    156           Glibc package) supports the GNU-style hash table, and this LFS
    157           edition does not support the o32 ABI.  So this is used to make the
    158           linker generate the GNU-style hash table instead of the classic
    159           ELF hash table by default, as the GNU-style hash table is faster
    160           to query.</para>
     151          <para>By default, the linker would generate both the GNU-style
     152          hash table and the classic ELF hash table for shared libraries and
     153          dynamically linked executables.  The hash tables are only intended
     154          for a dynamic linker to perform symbol lookup.  On LFS the dynamic
     155          linker (provided by the Glibc package) will always use the
     156          GNU-style hash table which is faster to query.  So the classic
     157          ELF hash table is completely useless.  This makes the linker
     158          only generate the GNU-style hash table by default, so we can avoid
     159          wasting time to generate the classic ELF hash table when we build
     160          the packages, or wasting disk space to store it.</para>

    1111  <title>LFS Target Architectures</title>
    1212
    13 <para>The primary target architectures of this LFS edition are the little
    14 endian MIPS64 release 2 to 5 CPUs (the release 6 is not backward-compatible
    15 with earlier releases).  On the other hand, the instructions
    16 in this book are also known to work, with some modifications, for
    17 MIPS CPUs with a different byte order, word size, or ISA version.  To
     13<para>The primary target architectures of LFS are the AMD/Intel x86 (32-bit)
     14and x86_64 (64-bit) CPUs.  On the other hand, the instructions in this book are
     15also known to work, with some modifications, with the Power PC and ARM CPUs. To
    1816build a system that utilizes one of these alternative CPUs, the main prerequisite, in
    1917addition to those on the next page, is an existing Linux system such as an
    2018earlier LFS installation, Ubuntu, Red Hat/Fedora, SuSE, or some other distribution
    21 that targets that architecture.</para>
     19that targets that architecture. (Note that a 32-bit
     20distribution can be installed and used as a host system on a 64-bit AMD/Intel
     21computer.)</para>
    2222
    23 <para>There are three widely-used ABIs for 64-bit MIPS programs.
    24 The <quote>o32</quote> ABI is compatible with the ABI of the legacy 32-bit
    25 MIPS programs and it's used for running those legacy 32-bit programs on a
    26 64-bit MIPS CPU.  The <quote>n64</quote> ABI is designed for taking the full
    27 advantage of 64-bit capability.  The <quote>n32</quote> ABI is similar to
    28 n64 but using 32-bit pointers, mainly used for 64-bit devices with a small
    29 amount of RAM. The default 64-bit build that results from LFS is a
    30 <quote>pure</quote> n64 system. That is, it supports n64 executables
     23<para>The gain from building on a 64-bit system, as
     24compared to a 32-bit system, is minimal.
     25For example, in a test build of LFS-9.1 on a Core i7-4790 CPU based system,
     26using 4 cores, the following statistics were measured:</para>
     27
     28<screen><computeroutput>Architecture Build Time     Build Size
     2932-bit       239.9 minutes  3.6 GB
     3064-bit       233.2 minutes  4.4 GB</computeroutput></screen>
     31
     32<para>As you can see, on the same hardware, the 64-bit build is only 3% faster
     33(and 22% larger) than the 32-bit build. If you plan to use LFS as a LAMP
     34server, or a firewall, a 32-bit CPU may be good enough. On the other
     35hand, several packages in BLFS now need more than 4 GB of RAM to be built
     36and/or to run; if you plan to use LFS as a desktop, the LFS authors
     37recommend building a 64-bit system.</para>
     38
     39<para>The default 64-bit build that results from LFS is a
     40<quote>pure</quote> 64-bit system. That is, it supports 64-bit executables
    3141only. Building a <quote>multi-lib</quote> system requires compiling many
    32 applications multiple times, each time for an ABI to be supported.
     42applications twice, once for a 32-bit system and once for a 64-bit system.
    3343This is not directly supported in LFS because it would interfere with the
    3444educational objective of providing the minimal instructions needed for a

    3646of LFS, accessible at <ulink
    3747url="https://www.linuxfromscratch.org/~thomas/multilib/index.html"/>. But
    38 it's for x86_64, and anyway multilib is an advanced topic.</para>
