34 <title>Introduction to GCC</title>
35
36 <para>The <application>GCC</application> package contains GNU compilers.
37 This package is useful for compiling programs written in C, C++, Fortran,
38 Java, Objective C and Ada. Also included is GNU Treelang. Treelang is a
39 sample language, useful only to help people understand how to implement a
40 new language front end to GCC. It is not a useful language in itself other
41 than as an example or basis for building a new language. Therefore only
42 language developers are likely to have an interest in it.</para>
43
44 <note>
45 <para>The Fortran compiler included with the
46 <application>GCC</application>-4.x package now aims to be conformant
47 with the Fortran 95 standard, not the Fortran 77 standard as all previous
48 versions of <application>GCC</application> have been. Please note the
49 following paragraph copied directly from the
50 <application>GCC</application>-&gcc-version; <command>gfortran</command>
51 man page.</para>
52
53 <para><quote>Gfortran is not yet a fully conformant Fortran 95 compiler.
54 It can generate code for most constructs and expressions, but work
55 remains to be done. In particular, there are known deficiencies with
56 ENTRY, NAMELIST, and sophisticated use of MODULES, POINTERS and DERIVED
57 TYPES. For those whose Fortran codes conform to either the Fortran 77
58 standard or the GNU Fortran 77 language, we recommend to use
59 <command>g77</command> from <application>GCC</application>
60 3.4.x</quote></para>

167 <para>The installation process may overwrite your existing

170 that you have the <application>Tcl</application>,
171 <application>Expect</application> and <application>DejaGnu</application>
172 packages installed before beginning the build so you can run the full
173 suite of tests.</para>
174
175 <para>Do not continue with the <command>make install</command> command
176 until you are confident the build was successful. You can compare your
177 test results with those found at
178 <ulink url="http://gcc.gnu.org/ml/gcc-testresults/"/>. There's also an
179 i686 platform test result produced by an LFS-SVN-20070304 system at
180 <ulink url="&files-anduin;/gcc412_test.txt"/>. You
181 may also want to refer to the information found in the

189 assumed that the current version of <application>GCC</application> is
190 installed in LFS, because this installation includes the Ada compiler as an
191 installed language, a bootstrap is required. The GNAT compiler must be used
192 for stage1 of the bootstrap in order to build Ada. If the process didn't
193 use a <quote>bootstrap</quote> you could end up having a
194 <command>gcc</command> installed on the system that was produced by a

597 <para>is largely a cut down version of C, designed to showcase the
598 features of the <application>GCC</application> code generation back
599 end. Only those features that are directly supported by the
600 <application>GCC</application> code generation back end are
601 implemented. Features are implemented in a manner which is easiest
602 and clearest to implement. Not all or even most code generation back
603 end features are implemented. The intention is to add features
604 incrementally until most features of the
605 <application>GCC</application> back end are implemented in
606 Treelang.</para>
