| 464 * include/hal_cache.h (HAL_DCACHE_STORE): | |
| 465 Added "register" keywords to the variables used in this macro. If | |
| 466 these are not in registers then when the cache is disabled, they | |
| 467 can be stranded in the cache and the random values in main memory | |
| 468 are used instead. This is only a problem when optimization is | |
| 469 disabled; under optimization the compiler puts these variables | |
| 470 into registers as a matter of course. | |

| 773 | |
| 774 * src/hal_misc.c: | |
| 775 Added calls to turn the caches on. But disabled them | |
| 776 since they interact poorly with Cygmon (Cygmon does not | |
| 777 flush the caches when setting/clearing breakpoints). | |
| 778 | |
