The traditional solution to + * this problem has been for each feature to have its own @c #ifdef + * option, allowing the feature to be compiled in only if desired. + * + * The problem with this is that it becomes impossible to compile, let + * alone test, all possible versions of Etherboot. Code that is not + * typically used tends to suffer from bit-rot over time. It becomes + * extremely difficult to predict which combinations of compile-time + * options will result in code that can even compile and link + * correctly. + * + * To solve this problem, we have adopted a new approach from + * Etherboot 5.5 onwards. @c #ifdef is now "considered harmful", and + * its use should be minimised. Separate features should be + * implemented in separate @c .c files, and should \b always be + * compiled (i.e. they should \b not be guarded with a @c #ifdef @c + * MY_PET_FEATURE statement). By making (almost) all code always + * compile, we avoid the problem of bit-rot in rarely-used code. + * + * The file config.h, in combination with the @c make command line, + * specifies the objects that will be included in any particular build + * of Etherboot. For example, suppose that config.h includes the line + * + * @code + * + * #define CONSOLE_SERIAL + * #define DOWNLOAD_PROTO_TFTP + * + * @endcode + * + * When a particular Etherboot image (e.g. @c bin/rtl8139.zdsk) is + * built, the options specified in config.h are used to drag in the + * relevant objects at link-time. For the above example, serial.o and + * tftp.o would be linked in. + * + * There remains one problem to solve: how do these objects get used? + * Traditionally, we had code such as + * + * @code + * + * #ifdef CONSOLE_SERIAL + * serial_init(); + * #endif + * + * @endcode + * + * in main.c, but this reintroduces @c #ifdef and so is a Bad Idea. + * We cannot simply remove the @c #ifdef and make it + * + * @code + * + * serial_init(); + * + * @endcode + * + * because then serial.o would end up always being linked in. + * + * The solution is to use @link tables.h linker tables @endlink. + * + */ + +/** @file + * + * Linker tables + * + * Read @ref ifdef_harmful first for some background on the motivation + * for using linker tables. + * + * This file provides macros for dealing with linker-generated tables + * of fixed-size symbols. We make fairly extensive use of these in + * order to avoid @c #ifdef spaghetti and/or linker symbol pollution. + * For example, instead of having code such as + * + * @code + * + * #ifdef CONSOLE_SERIAL + * serial_init(); + * #endif + * + * @endcode + * + * we make serial.c generate an entry in the initialisation function + * table, and then have a function call_init_fns() that simply calls + * all functions present in this table. If and only if serial.o gets + * linked in, then its initialisation function will be called. We + * avoid linker symbol pollution (i.e. always dragging in serial.o + * just because of a call to serial_init()) and we also avoid @c + * #ifdef spaghetti (having to conditionalise every reference to + * functions in serial.c). + * + * The linker script takes care of assembling the tables for us. All + * our table sections have names of the format @c .tbl.NAME.NN where + * @c NAME designates the data structure stored in the table (e.g. @c + * init_fns) and @c NN is a two-digit decimal number used to impose an + * ordering upon the tables if required. @c NN=00 is reserved for the + * symbol indicating "table start", and @c NN=99 is reserved for the + * symbol indicating "table end". + * + * As an example, suppose that we want to create a "frobnicator" + * feature framework, and allow for several independent modules to + * provide frobnicating services. Then we would create a frob.h + * header file containing e.g. + * + * @code + * + * struct frobnicator { + * const char *name; // Name of the frobnicator + * void ( *frob ) ( void ); // The frobnicating function itself + * };
