Lioncash 8af6bfb8b0 VideoCommon/ShaderGenCommon: Add function for writing fmt-based strings
Begins the conversion of the shader generators over to using fmt
formatting specifiers.

This also has a benefit over the older StringFromFormat-based API in
that all formatted data is appended to the existing buffer rather than
creating a completely separate string and then appending it to the
internal string buffer.

Techjar cd3ba570df VideoCommon/ShaderGenCommon: Fix memcmp size in ShaderUid operators 2019-05-30 16:00:46 -04:00
Lioncash f7eff6dab8 VideoCommon/ShaderGenCommon: Simplify operator!= for ShaderUid
This can be implemented as the negation of operator==, placing the
comparison logic for equality and inequality in the same place.

Lioncash 954246d10e VideoCommon/ShaderGenCommon: Remove use of a union within ShaderUid
This is only ever used to retrieve a raw view of the given UID data
structure, however it's already valid C++ to retrieve a char/unsigned
char view of an object for bytewise inspection.

u8 maps to unsigned char on all platforms we support, so we can just do
this directly with a reinterpret cast, simplifying the overall
interface.

Lioncash 149a97e396 VideoCommon: Remove unnecessary memset on ShaderUid instances.
Zero-initialization zeroes out all members and padding bits, so this is
safe to do. While we're at it, also add static assertions that enforce
the necessary requirements of a UID type explicitly within the ShaderUid
class.

This way, we can remove several memset calls around the shader
generation code that makes sure the underlying UID data is zeroed out.
Now our ShaderUid class enforces this for us, so we don't need to care about
it at the usage sites.

For some GLES drivers that don't support dual-source blending, but do
support GL_EXT_shader_framebuffer_fetch, this might be useful.

Scott Mansell 95469ec225 Remove UID Checker.
Kind of pointless now that multiple shaders with the same UID are
now fundementally impossible.

Scott Mansell 4969415f38 Remove global refrences from common code.
Bug Fix: Previously vertex shaders and geometery shaders didn't track
         antialaising state in their UIDs, which could cause AA bugs
	 on directx.

Stenzek e6b2212ec0 ShaderGen: Only specify storage qualifier in interface block when needed
Drivers that don't support GL_ARB_shading_language_420pack require that
the storage qualifier be specified even when inside an interface block.

AMD's driver throws a compile error when "centroid in/out" is used within
an interface block.

Our previous behavior was to include the storage qualifier regardless, but
this wasn't working on AMD, therefore we should check for the presence of
the extension and include based on this, instead.

Ryan Houdek 3ab7806e24 Workaround OS X video driver bug #24983074
OS X's shader compiler has a bug with interface blocks where interface block members don't properly inherit the layout qualifier from the interface
block.
Work around this limitation by explicitly stating the layout qualifier on both the interface block and every single member inside of that block.

Lioncash d9fec92628 VideoCommon: Header cleanup

Stenzek 617f9d9532 ShaderGen: Remove virtual methods from ShaderGeneratorInterface, move string buffer to ShaderCode
This fixes the crashes occuring at startup with a non-empty shader cache.
Because LinearDiskCache reads/writes to the storage of ShaderUid, ShaderUid must be trivially copyable.
Additionally, adds a static assert to LinearDiskCache to ensure this doesn't happen in the future.

The initialization of ShaderUid data has been moved to the code generation functions, so the above condition holds true.

NanoByte011 937844b9e3 Initial port of zfreeze branch (3.5-1729)
Initial port of original zfreeze branch (3.5-1729) by neobrain into
most recent build of Dolphin.

Makes Rogue Squadron 2 very playable at full speed thanks to recent core
speedups made to Dolphin. Works on DirectX Video plugin only for now.

Enjoy!  and Merry Xmas!!

Scott Mansell 1b771deb56 Move worldpos into it's own varying.
Previously it was packed into spare slots in clippos.xy and normal.w,
but it's ugly and more importantly it's causing bugs.

This was discovered during the debugging of a zfreeze branch, which
expected clippos.xy to be xy position coordinates in clipspace (as
the name suggested).

Turns out the stereoscopy shader had also run into this trap, modifying
clippos.x (introducing errors with per-pixel lighting).

This commit has been moved outside of the zfreeze PR for fast merging.
