| 554 * include/hal_cache.h (HAL_DCACHE_STORE): | |
| 555 Added "register" keywords to the variables used in this macro. If | |
| 556 these are not in registers then when the cache is disabled, they | |
| 557 can be stranded in the cache and the random values in main memory | |
| 558 are used instead. This is only a problem when optimization is | |
| 559 disabled; under optimization the compiler puts these variables | |
| 560 into registers as a matter of course. | |

| 724 Modified call to cyg_instrument() to pass table offset as well as | |
| 725 vector number. | |
| 726 Include <pkgconf/kernel.h> to allow call to cyg_instrument() to be | |

| 776 supporting thread-aware debugging easier. | |
| 777 | |

| 813 * src/vectors.S: | |
| 814 Moved NMI and TRAP VSRs down 1 word to match cygmon's use of the | |
| 815 vector table. This may need to change back in the future. | |
| 816 | |
| 817 1998-09-01 Nick Garnett <nickg@cygnus.co.uk> | |
| 818 | |
| 819 * include/hal_intr.h: | |

| 821 Modified HAL_TRANSLATE_VECTOR() for mn103002 to provide slots | |
| 822 for the NMI vectors at start of hal_interrupt_* tables. | |
| 823 | |
| 824 * src/hal_misc.c (exception_handler): | |

| 826 ISR if present. | |
| 827 | |
| 828 * src/vectors.S: | |
| 829 Modified behaviour of __default_nmi_vsr to support watchdog timer | |
| 830 properly. | |
| 831 Fixed indirection bug in __nmi and __trap. | |
| 832 Modified offsets in hal_interrupt_* tables to provide slots for | |

| 843 rename __main() to cyg_hal_invoke_constructors() and remove | |
| 844 initialised test | |
| 845 | |
| 846 * src/vectors.S (_start): | |

| 848 of main() to cyg_start() | |
| 849 | |
| 850 1998-08-25 Nick Garnett <nickg@cygnus.co.uk> | |

| 863 | |
| 864 * src/hal_misc.c: | |
| 865 Added calls to turn the caches on. But disabled them | |
| 866 since they interact poorly with Cygmon (Cygmon does not | |
| 867 flush the caches when setting/clearing breakpoints). | |
| 868 | |
| 869 Wed Aug 19 18:19:32 1998 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 870 | |
