/* This code tries to make movcal emulation sufficiently
|
500 |
accurate for Linux purposes. This instruction writes
|
501 |
memory, and prior to that, always allocates a cache line.
|
502 |
It is used in two contexts:
|
503 |
- in memcpy, where data is copied in blocks, the first write
|
504 |
of to a block uses movca.l for performance.
|
505 |
- in arch/sh/mm/cache-sh4.c, movcal.l + ocbi combination is used
|
506 |
to flush the cache. Here, the data written by movcal.l is never
|
507 |
written to memory, and the data written is just bogus.
|
508 |
|
509 |
To simulate this, we simulate movcal.l, we store the value to memory,
|
510 |
but we also remember the previous content. If we see ocbi, we check
|
511 |
if movcal.l for that address was done previously. If so, the write should
|
512 |
not have hit the memory, so we restore the previous content.
|
513 |
When we see an instruction that is neither movca.l
|
514 |
nor ocbi, the previous content is discarded.
|
515 |
|
516 |
To optimize, we only try to flush stores when we're at the start of
|
517 |
TB, or if we already saw movca.l in this TB and did not flush stores
|
518 |
yet. */
