1407 | /* Perform arch-dependent adjustments to a register name. |
1408 | ||
1409 | In very specific situations, it may be necessary for the register | |
1410 | name present in a SystemTap probe's argument to be handled in a | |
1411 | special way. For example, on i386, GCC may over-optimize the | |
1412 | register allocation and use smaller registers than necessary. In | |
1413 | such cases, the client that is reading and evaluating the SystemTap | |
1414 | probe (ourselves) will need to actually fetch values from the wider | |
1415 | version of the register in question. | |
1416 | ||
1417 | To illustrate the example, consider the following probe argument | |
1418 | (i386): | |
1419 | ||
1420 | 4@%ax | |
1421 | ||
1422 | This argument says that its value can be found at the %ax register, | |
1423 | which is a 16-bit register. However, the argument's prefix says | |
1424 | that its type is "uint32_t", which is 32-bit in size. Therefore, in | |
1425 | this case, GDB should actually fetch the probe's value from register | |
1426 | %eax, not %ax. In this scenario, this function would actually | |
1427 | replace the register name from %ax to %eax. | |
1428 | ||
1429 | The rationale for this can be found at PR breakpoints/24541. */ | |

1722 | GDB targets (*-tdep.c) can register an interest in a specific | |
1723 | architecture. Other GDB components can register a need to maintain | |
1724 | per-architecture data. | |

1734 | didn't scale. | |

1737 | data for all the various GDB components was also considered. Since | |
99e7bb18 | 1738 | GDB is built from a variable number of (fairly independent) |
0f71a2f6 | 1739 | components it was determined that the global aproach was not |

1747 | selected, the corresponding INIT function is called. | |
1748 | ||
1749 | -- | |
1750 | ||
1751 | The INIT function takes two parameters: INFO which contains the | |
1752 | information available to gdbarch about the (possibly new) | |
1753 | architecture; ARCHES which is a list of the previously created | |

7a107747 | 1757 | information obtained from INFO.ABFD or the global defaults. |
0f79675b AC |
1758 | |
1759 | The ARCHES parameter is a linked list (sorted most recently used) | |
1760 | of all the previously created architures for this architecture | |
1761 | family. The (possibly NULL) ARCHES->gdbarch can used to access | |
1762 | values from the previously selected architecture for this | |

ec3d358c | 1766 | doesn't recognize the selected architecture; an existing ``struct |
0f71a2f6 JM |
1767 | gdbarch'' from the ARCHES list - indicating that the new |
1768 | architecture is just a synonym for an earlier architecture (see | |
1769 | gdbarch_list_lookup_by_info()); a newly created ``struct gdbarch'' | |
4b9b3959 AC |
1770 | - that describes the selected architecture (see gdbarch_alloc()). |
