| 32 |
|
|

| 33 |
|
|
* o) Big-endian ARM loads/stores. |
| 34 |
|
|
* |
| 35 |
|
|
* o) Alignment checks! |
| 36 |
|
|
* |
| 37 |
|
|
* o) Native load/store if the endianness is the same as the host's |
| 38 |
dpavlin |
18 |
* (only implemented for little endian, so far, and it assumes that |
| 39 |
|
|
* alignment is correct!) |
| 40 |
dpavlin |
14 |
* |
| 41 |
|
|
* o) "Base Updated Abort Model", which updates the base register |
| 42 |
|
|
* even if the memory access failed. |
| 43 |
|
|
* |
| 44 |
|
|
* o) Some ARM implementations use pc+8, some use pc+12 for stores? |
| 45 |
|
|
* |
| 46 |
|
|
* o) All load/store variants with the PC register are not really |
| 47 |
|
|
* valid. (E.g. a byte load into the PC register. What should that |
| 48 |
|
|
* accomplish?) |
| 49 |
|
|
* |
| 50 |
|
|
* o) Perhaps an optimization for the case when offset = 0, because |
| 51 |
|
|
* that's quite common, and also when the Reg expression is just |
| 52 |
|
|
* a simple, non-rotated register (0..14). |

| 319 |

|
* o) Loads into the PC register cause a branch. If an exception occured |
| 320 |
|
|
* during the load, then the PC register should already point to the |
| 321 |
|
|

|
|
* second time (no harm is done by doing that). |
| 323 |

|
* |
| 324 |
|
|
* TODO: A tiny performance optimization would be to separate the two |
| 325 |

|
* cases: a load where arg[0] = PC, and the case where arg[2] = PC. |
