1443 | In very specific situations, it may be necessary for the register |
1444 | name present in a SystemTap probe's argument to be handled in a | |
1445 | special way. For example, on i386, GCC may over-optimize the | |

1447 | such cases, the client that is reading and evaluating the SystemTap | |
1448 | probe (ourselves) will need to actually fetch values from the wider | |
1449 | version of the register in question. | |
fb14eb08 | 1450 | |

1451 | To illustrate the example, consider the following probe argument |
1452 | (i386): | |

1453 | |
1454 | 4@%ax | |
1455 | ||
2b7c3f1d TT |
1456 | This argument says that its value can be found at the %ax register, |
