We currently have a bug when calling Arm64GPRCache::Flush with
FlushMode::MaintainState, zero free host registers, and at least
one guest register containing an immediate. We end up grabbing
a temporary register from the register cache in order to be
able to write the immediate to memory, but grabbing a temporary
register when there are zero free registers causes the least
recently used register to be flushed in a way which does not
maintain the state of the register cache.
To get around this, require callers to pass in a temporary
register in the GPR MaintainState case. In other cases,
passing in a temporary register is not required but can help
avoid spilling a register (if the caller already had a
temporary register at hand anyway, which in particular will
be the case in my upcoming memcheck pull request).
release-ubu-x64 currently fails with "sorry, unimplemented: non-trivial
designated initializers not supported". pr-ubu-x64 doesn't for some
reason, but we might as well remove the designated initializer.
This fixes various texture offsetting issues with negative texture coordinates (bringing the software renderer in line with the hardware renderers). It also handles the invalid wrap mode accurately (as was done for the hardware renderers in the previous commit). Lastly, it handles wrapping with non-power-of-2 texture sizes in a hardware-accurate way (which is somewhat broken looking, as games aren't supposed to use wrapping with non-power-of-2 sizes); this has not been done for the hardware renderers.
A voice is considered running if and only if `running` equals 1,
not if `running` is not equal to 0.
This fixes https://bugs.dolphin-emu.org/issues/12508 because for some
reason *The Sims 2 - Castaway* sets `running` to 8 when a stream
finishes playing; previously our AX HLE would just loop the voice
and eventually crash after accessing invalid memory addresses.
Thanks to JMC47 and delroth's help, I've verified that this is the
correct check for the following ucodes:
GC:
* 0x3ad3b7ac
* 0x3daf59b9
* 0x4e8a8b21
* 0x07f88145
* 0xe2136399
* 0x3389a79e
Wii:
* 0x347112ba
* 0xfa450138
* 0xadbc06bd
And while I was fixing the running check, I noticed that the is_stream
field was also being handled incorrectly, so I've fixed that as well.
