Before these changes each value of latency were actually 5ms, with a
minimum latency of ~10 ms. If it was set to 4 ms on the UI, the actual
latency was 10 + 5 * 4 = 30 ms.
Now 30 ms on the UI means 30 ms on the backend.
OpenALStream was querying the backend for AL_EXT_float32 support (which
suceeds), but AL_FORMAT_STEREO_FLOAT32 was defined incorrectly.
Also changes OpenALStream to query for AL_EXT_MCFORMATS (multichannel
support) rather than hard-coding that it doesn't work on macOS.
Fixes an error with the CoreAudio backend, which apparently doesn't
allow you to set the volume before starting the stream:
```
59:31:087 AudioCommon/CoreAudioSoundStream.cpp:97 E[Audio]: error setting volume
```
This shouldn't cause any problems with other backends, since the mixer
starts with silence anyways.
This moves all the byte swapping utilities into a header named Swap.h.
A dedicated header is much more preferable here due to the size of the
code itself. In general usage throughout the codebase, CommonFuncs.h was
generally only included for these functions anyway. These being in their
own header avoids dumping the lesser used utilities into scope. As well
as providing a localized area for more utilities related to byte
swapping in the future (should they be needed). This also makes it nicer
to identify which files depend on the byte swapping utilities in
particular.
Since this is a completely new header, moving the code uncovered a few
indirect includes, as well as making some other inclusions unnecessary.
We (the Microsoft C++ team) use the dolphin project as part of our "Real world code" tests.
I noticed a few issues in windows specific code when building dolphin with the MSVC compiler
in its conformance mode (/permissive-). For more information on /permissive- see our blog
https://blogs.msdn.microsoft.com/vcblog/2016/11/16/permissive-switch/.
These changes are to address 3 different types of issues:
1) Use of qualified names in member declarations
struct A {
void A::f() { } // error C4596: illegal qualified name in member declaration
// remove redundant 'A::' to fix
};
2) Binding a non-const reference to a temporary
struct S{};
// If arg is in 'in' parameter, then it should be made const.
void func(S& arg){}
int main() {
//error C2664: 'void func(S &)': cannot convert argument 1 from 'S' to 'S &'
//note: A non-const reference may only be bound to an lvalue
func( S() );
//Work around this by creating a local, and using it to call the function
S s;
func( s );
}
3) Add missing #include <intrin.h>
Because of the workaround you are using in the code you will need to include
this. This is because of changes in the libraries and not /permissive-
