Philip Rebohle	3a993d0c5c	[dxvk] Use only one spec constant for fragment shader output component mapping ... Let's trust the driver to be able to constant-fold bitfieldExtract operations.	2021-01-29 16:17:07 +01:00

Philip Rebohle	538b55921e	[dxbc] Conditionally return zeroes for unbound textures in shader ... May allow the driver to optimize away texture operations.	2020-11-24 18:39:20 +01:00
Philip Rebohle	45461ee54e	[dxbc] Use opSelect for unbound texel fetch instructions ... Generates less annoying code compared to control flow instructions, and drivers should be able to optimize away the texture instruction anyway since the bound state is a specialization constant.	2020-11-24 18:36:40 +01:00
Philip Rebohle	61a07fc9b9	[dxbc] Fix up incorrect infinity returned by f32tof16 ... Completely insane fix for #1826.	2020-11-21 01:25:03 +01:00

Joshua Ashton	62c2c9cd15	[dxbc] Handle 0 divisors in UDiv ... UDiv is defined as having 0xffffffff as both the quotient and remainder value when the divisor is 0 This fixes vertex corruption on the water bottles in Half-Life: Alyx https://github.com/ValveSoftware/Proton/issues/3681 https://docs.microsoft.com/en-us/windows/win32/direct3dhlsl/udiv--sm4---asm-	2020-03-26 10:49:42 +01:00

Philip Rebohle	11f08c7dea	[dxbc] Declare vertex positions as invariant ... Otherwise, games relying on different vertex shaders to produce the same numerical results may suffer from Z-fighting issues. Fixes #1364.	2020-01-22 23:59:51 +01:00
Philip Rebohle	6690a31d8d	[dxbc] Don't enable SPV_KHR_shader_draw_parameters ... Core in SPIR-V 1.3.	2020-01-17 17:46:59 +01:00
Philip Rebohle	31948cae8c	[spirv] Allow specifying the SPIR-V version explicitly ... We're going to use some SPIR-V 1.4 features for D3D11 if supported, but 1.4 is not supported by all implementations.	2019-12-18 17:36:46 +01:00

Philip Rebohle	49e7df96ec	[dxbc] Emit a spec constant for uniform buffers ... This partially reverts commit fd547b666e5324f29eff47f2838832f273bb0fed. For some reason, not doing so breaks Overwatch (because of course it does).	2019-11-28 00:55:38 +01:00
Philip Rebohle	c4e5323e0e	[dxbc] Remove old constant buffer range check	2019-10-28 17:52:50 +01:00

Philip Rebohle	3d213efe53	[dxbc] Use SSBOs for dynamically indexed constant buffers if needed ... SSBOs are tightly bound-checked on all Nvidia GPUs, so this allows for a more accurate workaround for games relying on OOB access behaviour.	2019-10-28 15:42:46 +01:00
Philip Rebohle	6888a98c89	[dxbc] Always set geometry shader invocation count ... Fixes validation errors when the DXBC shader does not specify the invocation count itself.	2019-10-26 23:19:59 +02:00
Philip Rebohle	144f4badef	[dxbc] Always allocate at least one input array element ... Turns out that shaders with no inputs can still have an input signature, in which case we were generating a zero-length array which is illegal.	2019-10-26 23:13:59 +02:00
Philip Rebohle	2d6a3396dd	[dxbc] Declare length of shader input array late ... Otherwise, we generate out-of-bounds array reads and writes in broken ENB shaders.	2019-10-23 16:36:52 +02:00
Philip Rebohle	59d4556641	[dxbc] Extend scalar constants to vectors if required ... Needed for ENB. Fixes #865.	2019-10-23 15:26:22 +02:00

Philip Rebohle	8211225ad4	[dxbc] Swap OpSelect arguments for Ne/Dne, don't use OpLogicalNot ... Saves one instruction.	2019-10-18 03:22:20 +02:00
Philip Rebohle	803ec3542d	[dxbc] Fix sample positions ... From the D3D11.3 functional specification: "The sample position is relative to the pixel's center" Fixes wine test failures.	2019-10-11 18:41:10 +02:00
Philip Rebohle	59d4e8a36a	[dxbc] Fix NaN handling in not-equal comparison ... Ne and Dne are unordered in DXBC. Avoid FUnordNotEqual to avoid potential issues with drivers and debugging tools.	2019-09-30 00:19:47 +02:00
Philip Rebohle	b6cf518962	Revert "[dxbc] Always decorate SV_POSITION as invariant" ... This reverts commit 5ee790a4a37e302d61d1aecb5f259e5072155c6c. Breaks Shadow of the Tomb Raider on Nvidia for unknown reasons.	2019-09-24 23:01:36 +02:00
Philip Rebohle	5ee790a4a3	[dxbc] Always decorate SV_POSITION as invariant ... Apparently fixes Z-Fighting in Saints Row IV on Nvidia.	2019-09-24 22:19:43 +02:00
Philip Rebohle	f38cfd592e	[dbxc] Actually fix callc implementation ... Yeah maybe we should close our blocks properly. There seems to be no way to generate a callc instruction with fxc so this is untested.	2019-09-22 22:36:42 +02:00
Philip Rebohle	94ce76da6b	[dxbc] Implement label, call and callc instructions ... Fixes #1200.	2019-09-22 22:28:58 +02:00
Philip Rebohle	17a6c4168e	[dxbc] Implement stencil ref export from fragment shaders ... This is an optional feature in D3D11.3, but easy enough to support.	2019-09-16 12:42:15 +02:00
Philip Rebohle	26afaba410	[dxbc] Implement MSAD4 instruction ... Apparently we're required to support this for Direct3D 11.2+. There are currently no known games that require this instruction.	2019-09-16 12:42:14 +02:00
Philip Rebohle	6ab074c95b	[dxbc] Only use atomic append/consume optimization in compute shaders ... - For fragment shaders, this isn't safe since ballots include helper invocations - For vertex shaders, if drivers don't support subgroup operations in those stages, we don't want it to affect the performance of compute shadres.	2019-07-26 14:07:39 +02:00
Philip Rebohle	9c5102e257	[dxvk] Don't duplicate geometry shader system value outputs ... Fixes #1121. The basic idea here is that all built-ins that can be written by the GS will be consumed as built-ins by the FS anyway, so we do not need to keep the o# variable around.	2019-07-24 18:18:20 +02:00
Philip Rebohle	8644d75722	[dxbc] Use OpDemoteToHelperInvocationEXT for discards if supported	2019-07-11 19:33:17 +02:00

Philip Rebohle	d755b18ccb	[dxbc] Repurpose useRawSsbo option ... Basically, abuse the minSsboAlignment property to convince the compiler to always/never emit raw SSBOs for raw and structured buffers, and use the actual device limit by default.	2019-06-11 20:20:40 +02:00
Philip Rebohle	0f7c23c022	[dxbc] Always use raw storage buffers if alignment requirements are met	2019-06-11 20:20:40 +02:00
Philip Rebohle	163e6aaa50	[dxbc] Store alignment for raw and structured buffers	2019-06-11 20:20:40 +02:00
Philip Rebohle	7d9a75c82c	[dxbc] Use subgroup operations for atomic append/consume operations ... Reduces the number of atomic operations performed per subgroup to 1.	2019-05-15 19:32:27 +02:00

Philip Rebohle	dc3cfc9fa0	[dxbc] Use new spec constant API for rasterizer sample count	2019-05-01 01:57:34 +02:00
Philip Rebohle	7111af423d	[dxbc] Add new emitNewSpecConstant method ... Convenience method to declare new specialization constants.	2019-05-01 01:57:34 +02:00
Philip Rebohle	3b1e753bb5	[dxvk] Re-implement early discard with quad granularity ... May perform better on some hardware in situations where we cannot discard a full subgroup. Closes #753.	2019-04-30 14:46:03 +02:00
Danylo Piliaiev	261d31cac6	[dxbc] Fix xfb passthrough for system values ... vReg should be always allocated for system values which is necessary for emitXfbOutputSetup and is already done for hull shader passthrough. Signed-off-by: Danylo Piliaiev <danylo.piliaiev@globallogic.com>	2019-04-30 12:19:21 +02:00
Philip Rebohle	06c144f075	[dxbc] Store sample positions as vec2 array ... We can append the zeroes in shader code instead. May improve generated code on drivers that use scratch memory or temporary uniform buffers for large arrays.	2019-04-29 14:04:42 +02:00
