Before, only the symbols box would update. However, if you edit the symbol of a function in the call stack (which seems like something that would happen reasonably often while debugging), the call stack would be out of date until it was updated by clicking on it. Callers and calls were more of an edge case; for them to be out of date, you would need to right-click on an instruction in a function other than the one containing the currently-selected instruction (though it would also affect recursive functions).
Tested on an official DOL-014 (251 blocks) memory card by executing the
0xf4 command on a card with content along its entire length and then
dumping the whole card: it reads as 0xff all the way through.
Therefor, the current implementation is already consistent with hardware.
Compared to the previous solution of using big `synchronized` blocks,
this makes GameFileCacheManager's executor thread release and re-lock
the lock when possible, giving the GUI thread a chance to do a
(comparatively) quick getOrAdd call if it needs to.
This reverts commit fb265b610d.
The optimization in that commit is safe when the executor thread is
writing and the GUI thread is reading, but I had failed to take into
account that it's unsafe when the GUI thread is writing and the executor
thread is reading. (The native UpdateAdditionalMetadata function loops
through m_cached_files, which is unsafe if another thread is adding
elements to m_cached_files simultaneously.)
Losing out on this optimization isn't too bad, because
719930bb39 makes it very unlikely that
both threads will want the lock at the same time.
Texture dumping can already be done using VideoCommon's system (and in fact the same setting already enabled *both* of these). Dumping objects/TEV stages/texture fetches doesn't currently have an equivalent, but could be added to the FIFO player instead.
A (partial) port of #9481 to ARM64. This commit adds special cases for
immediate values equal to 0 or 0xFFFFFFFF, allowing for more efficient
or no code to be generated.
When a guest register is an immediate, it may be necessary to move this
value into a register. This is handled by gpr.R(), which lacks context
on how the register will be used. This leads to cases where the
immediate is written to a register, only for it to be overwritten. Take
for example this code generated by srwx:
0x5280031b mov w27, #0x18
0x53187edb lsr w27, w22, #24
gpr.BindToRegister() does have this context through the do_load
parameter, but didn't handle immediates. By adding this logic, we can
intelligently skip the write when do_load is false.
This game follows the anti-pattern of calling memset on a buffer in the
midst of being DMA copied to ARAM, then calling a DVD read function that
effectively cancels the memset with dcbi instructions. Dolphin does not
emulate dcache for performance reasons, so this patch removes the
offending memset call.
