1 20 Makefile Fragments
1 *********************
1
1 When you configure GCC using the 'configure' script, it will construct
1 the file 'Makefile' from the template file 'Makefile.in'. When it does
1 this, it can incorporate makefile fragments from the 'config' directory.
1 These are used to set Makefile parameters that are not amenable to being
1 calculated by autoconf. The list of fragments to incorporate is set by
11 'config.gcc' (and occasionally 'config.build' and 'config.host'); ⇒
System Config.
1
1 Fragments are named either 't-TARGET' or 'x-HOST', depending on whether
1 they are relevant to configuring GCC to produce code for a particular
1 target, or to configuring GCC to run on a particular host. Here TARGET
1 and HOST are mnemonics which usually have some relationship to the
1 canonical system name, but no formal connection.
1
1 If these files do not exist, it means nothing needs to be added for a
1 given target or host. Most targets need a few 't-TARGET' fragments, but
1 needing 'x-HOST' fragments is rare.
