This is now unused. Seems like it was an improper fix
(there would be a race if saving the screenshot took longer
than 2 seconds) back when it was used too.
While manually capturing constexpr variables used in lambda
expressions does work, it's really easy to forget doing so since
we don't have a Windows CMake builder and the workaround isn't
necessary anywhere else. Fortunately, MSVC has a flag that fixes
the constexpr capture behavior, so let's use that instead.
These are only ever used with ShaderCode instances and nothing else.
Given that, we can convert these helper functions to expect that type of
object as an argument and remove the need for templates, improving
compiler throughput a marginal amount, as the template instantiation
process doesn't need to be performed.
We can also move the definitions of these functions into the cpp file,
which allows us to remove a few inclusions from the ShaderGenCommon
header. This uncovered a few instances of indirect inclusions being
relied upon in other source files.
One other benefit is this allows changes to be made to the definitions
of the functions without needing to recompile all translation units that
make use of these functions, making change testing a little quicker.
Moving the definitions into the cpp file also allows us to completely
hide DefineOutputMember() from external view, given it's only ever used
inside of GenerateVSOutputMembers().
A very trivial conversion, this simply converts calls to Write over to
WriteFmt and adjusts the formatting specifiers as necessary.
This also allows the const char* parameters to become std::string_view
instances, allowing for ease of use with other string types.
Lambda expressions with uncaptured constants were leading to errors,
and there were also some warnings about deprecated functions
(QFontMetrics::width and inet_ntoa).
It actually maps to postMtxInfo, not posMtxInfo (which isn't a thing).
This is especially confusing because there *are* position matrices (as
opposed to post-transform matrices).
It used to be the case that frame advance skipped duplicate frames
(i.e. it would take 30 frame advances to get through one second
of emulated time in a 30 fps game), but this broke in 9c5c3c0.
Skipping duplicate frames making TASing less annoying.
Hardware tests have shown that if the number of texgens/channels do not
match, you get garbage rendering. Presumably because the output
registers from the XF stage are fed into the incorrect input registers
for TEV/BP.
Currently, this causes Dolphin to crash/generate invalid shaders with an
assertion failure in the hardware backends. Instead, we log an error.
Perhaps in the future we should just spit out all texgens/colors anyway
from both stages, and let cross-stage optimization take care of DCE'ing
it away. But doing so would require changing the UIDs and invalidating
everyone's shader caches.
