| 76 | |
| 77 This manual documents the internals of the GNU compilers, including | |
| 78 how to port them to new targets and some information about how to | |
| 79 write front ends for new languages. It corresponds to the compilers | |
| 80 @ifset VERSION_PACKAGE | |
| 81 @value{VERSION_PACKAGE} | |
| 82 @end ifset | |
| 83 version @value{version-GCC}. The use of the GNU compilers is documented in a | |
| 84 separate manual. @xref{Top,, Introduction, gcc, Using the GNU | |
| 85 Compiler Collection (GCC)}. | |
| 86 | |
| 87 This manual is mainly a reference manual rather than a tutorial. It | |
| 88 discusses how to contribute to GCC (@pxref{Contributing}), the | |
| 89 characteristics of the machines supported by GCC as hosts and targets | |
| 90 (@pxref{Portability}), how GCC relates to the ABIs on such systems | |
| 91 (@pxref{Interface}), and the characteristics of the languages for | |
| 92 which GCC front ends are written (@pxref{Languages}). It then | |
| 93 describes the GCC source tree structure and build system, some of the | |
| 94 interfaces to GCC front ends, and how support for a target system is | |
| 95 implemented in GCC@. | |
| 96 | |
| 97 Additional tutorial information is linked to from | |
| 98 @uref{http://gcc.gnu.org/readings.html}. | |
