1274 | ||
1275 | A "special case" is considered to be an unknown token, i.e., a token | |
1276 | that the parser does not know how to parse. A good example of special | |
1277 | case would be ARM's register displacement syntax: | |
1278 | ||
1279 | [R0, #4] ;; displacing R0 by 4 | |
1280 | ||
1281 | Since the parser assumes that a register displacement is of the form: | |
1282 | ||
1283 | <number> <indirection_prefix> <register_name> <indirection_suffix> | |
1284 | ||
1285 | it means that it will not be able to recognize and parse this odd syntax. | |
1286 | Therefore, we should add a special case function that will handle this token. | |
1287 | ||
1288 | This function should generate the proper expression form of the expression | |
1289 | using GDB's internal expression mechanism (e.g., `write_exp_elt_opcode' | |
1290 | and so on). It should also return 1 if the parsing was successful, or zero | |
1291 | if the token was not recognized as a special token (in this case, returning | |
1292 | zero means that the special parser is deferring the parsing to the generic | |
1293 | parser), and should advance the buffer pointer (p->arg). */ | |

1302 | ||
1303 | In very specific situations, it may be necessary for the register | |
1304 | name present in a SystemTap probe's argument to be handled in a | |
1305 | special way. For example, on i386, GCC may over-optimize the | |
1306 | register allocation and use smaller registers than necessary. In | |
1307 | such cases, the client that is reading and evaluating the SystemTap | |
1308 | probe (ourselves) will need to actually fetch values from the wider | |
1309 | version of the register in question. | |
1310 | ||
1311 | To illustrate the example, consider the following probe argument | |
1312 | (i386): | |
1313 | ||
1314 | 4@%ax | |
1315 | ||
1316 | This argument says that its value can be found at the %ax register, | |
1317 | which is a 16-bit register. However, the argument's prefix says | |
1318 | that its type is "uint32_t", which is 32-bit in size. Therefore, in | |
1319 | this case, GDB should actually fetch the probe's value from register | |
1320 | %eax, not %ax. In this scenario, this function would actually | |
1321 | replace the register name from %ax to %eax. | |
1322 | ||
