990 | # Function used to handle a "special case" in the parser. | |
991 | # | |
992 | # A "special case" is considered to be an unknown token, i.e., a token | |
993 | # that the parser does not know how to parse. A good example of special | |
994 | # case would be ARM's register displacement syntax: | |
995 | # | |
996 | # [R0, #4] ;; displacing R0 by 4 | |
997 | # | |
998 | # Since the parser assumes that a register displacement is of the form: | |
999 | # | |
1000 | # <number> <indirection_prefix> <register_name> <indirection_suffix> | |
1001 | # | |
1002 | # it means that it will not be able to recognize and parse this odd syntax. | |
1003 | # Therefore, we should add a special case function that will handle this token. | |
1004 | # | |
1005 | # This function should generate the proper expression form of the expression | |
1006 | # using GDB\'s internal expression mechanism (e.g., \`write_exp_elt_opcode\' | |
1007 | # and so on). It should also return 1 if the parsing was successful, or zero | |
1008 | # if the token was not recognized as a special token (in this case, returning | |
1009 | # zero means that the special parser is deferring the parsing to the generic | |
1010 | # parser), and should advance the buffer pointer (p->arg). | |

1013 | # Perform arch-dependent adjustments to a register name. |
1014 | # | |
1015 | # In very specific situations, it may be necessary for the register | |
1016 | # name present in a SystemTap probe's argument to be handled in a | |
1017 | # special way. For example, on i386, GCC may over-optimize the | |
1018 | # register allocation and use smaller registers than necessary. In | |
1019 | # such cases, the client that is reading and evaluating the SystemTap | |
1020 | # probe (ourselves) will need to actually fetch values from the wider | |
1021 | # version of the register in question. | |
1022 | # | |
1023 | # To illustrate the example, consider the following probe argument | |
1024 | # (i386): | |
1025 | # | |
1026 | # 4@%ax | |
1027 | # | |
1028 | # This argument says that its value can be found at the %ax register, | |
1029 | # which is a 16-bit register. However, the argument's prefix says | |
1030 | # that its type is "uint32_t", which is 32-bit in size. Therefore, in | |
1031 | # this case, GDB should actually fetch the probe's value from register | |
1032 | # %eax, not %ax. In this scenario, this function would actually | |
1033 | # replace the register name from %ax to %eax. | |
1034 | # | |
1035 | # The rationale for this can be found at PR breakpoints/24541. | |
