| /* |
| * Note: The encoding map entries for vldrd and vldrs include REG_DEF_LR, even though |
| * these instructions don't define lr. The reason is that these instructions |
| * are used for loading values from the literal pool, and the displacement may be found |
| * to be insuffient at assembly time. In that case, we need to materialize a new base |
| * register - and will use lr as the temp register. This works because lr is used as |
| * a temp register in very limited situations, and never in conjunction with a floating |
| * point constant load. However, it is possible that during instruction scheduling, |
| * another use of lr could be moved across a vldrd/vldrs. By setting REG_DEF_LR, we |
| * prevent that from happening. Note that we set REG_DEF_LR on all vldrd/vldrs - even those |
| * not used in a pc-relative case. It is really only needed on the pc-relative loads, but |
| * the case we're handling is rare enough that it seemed not worth the trouble to distinguish. |
