The various format dcmds invoke the * mdb_fmt_print() function below with a target, address space identifier, * address, count, and format character, and it reads the required data from * the target and prints the formatted output to stdout. Since nearly two * thirds of the format characters can be expressed as simple printf format * strings, we implement the engine using the lookup table below. Each entry * provides either a pointer to a printf format string or a pointer to a * function to perform special processing. For the printf case, the * corresponding data size in bytes is also supplied. The printf processing * code handles 1, 2, 4, and 8-byte reads into an unsigned integer container * of the given size, and then simply calls mdb_iob_printf with the integer * and format string. This handles all printf cases, except when unsigned * promotion of an integer type in the varargs list does not perform the * conversion we require to get the proper result. With the current set of * format characters, this case only occurs twice: we need a 4-byte float * to get promoted to 8-byte double for the 'f' format so it can be * correctly formatted by %f, and we need a 1-byte int8_t to get promoted * with sign extension to a 4-byte int32_t for the 'v' format so it can be * correctly formatted by %d. We provide explicit functions to handle these * cases, as well as to handle special format characters such as 'i', etc. * We also provide a cmd_formats() dcmd function below which prints a table * of the output formats and their sizes. Format characters that provide * custom functions provide their help description string explicitly. All * the printf formats have their help strings generated automatically by * our printf "unparser" mdb_iob_format2str(). */ #include #include #include #include #include #include #include #define FUNCP(p) ((void *)(p)) /* Cast to f_ptr type */ #define SZ_NONE ((size_t)-1L) /* Format does not change dot */ typedef mdb_tgt_addr_t mdb_fmt_func_f(mdb_tgt_t *, mdb_tgt_as_t, mdb_tgt_addr_t, size_t); /* * There are several 'special' characters that are handled outside of * mdb_fmt_print().
