Philip Rebohle	2d670ec3db	[dxbc] Enable capabilities for float control modes ... Fixes some validation errors (but seriously, why does everything have to be a capability in SPIR-V?)	2021-01-29 16:29:39 +01:00
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	307f43ff1e	[d3d11] Introduce option to disable float controls ... And disable for SotTR since it introduces rendering issues.	2021-01-28 20:32:38 +01:00
Philip Rebohle	1478011822	[dxbc] Enable NaN fixup by default on older RADV versions ... And get rid of a whole bunch of game-specific workarounds.	2021-01-28 19:37:10 +01:00
Philip Rebohle	f5fa7a9099	[dxbc] Set float control bits as necessary	2021-01-28 19:37:10 +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

Rhys Perry	73cb711f32	[dxbc] Bounds-check temporary array stores ... Fixes flickering terrain in Just Cause 3 on RADV and possibly ANV.	2020-09-14 16:56:06 +02:00
Philip Rebohle	5750a7d85c	[dxbc] Fix the udiv crap again	2020-03-26 17:17:01 +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	f12ddfa4d3	[dxbc] Fix line tessellation factor ordering	2020-02-12 12:00:46 +01:00
Philip Rebohle	76a6f6eab9	[dxbc] Add option to force memory barriers after shared memory stores	2020-02-08 00:48:42 +01:00
Philip Rebohle	9721938e57	[d3d11] Introduce d3d11.invariantPosition option ... Apparently it's better to make app profiles than risk tanking performance for all applications. Invariance rules in D3D11 are undocumented so it's not clear what the correct solution is.	2020-01-23 01:28:19 +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	27ea176295	[d3d11] Remove d3d11.strictDivision option	2019-11-30 20:39:32 +01:00
Philip Rebohle	3b030d9569	[dxbc] Implement workaround to replace NaN render target outputs by zero	2019-11-30 20:39:32 +01:00
Philip Rebohle	49e7df96ec	[dxbc] Emit a spec constant for uniform buffers ... This partially reverts commit fd547b666e. For some reason, not doing so breaks Overwatch (because of course it does).	2019-11-28 00:55:38 +01:00
Philip Rebohle	e95bc3256f	[d3d11] Move handling of constantBufferRangeCheck option to D3D11Options	2019-10-30 10:57:36 +01:00

Philip Rebohle	fd547b666e	[dxbc] Don't emit a spec constant for uniform buffers	2019-10-28 15:44:02 +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	68760f5b20	[dxbc] Parse dynamically indexed flag for constant buffers	2019-10-28 14:15:44 +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	ec8ca8a403	[dxbc] Assume vec4 type for i/o vars not declared in signature ... Works around an ENB bug.	2019-10-23 15:26:22 +02:00
Philip Rebohle	3e12a116bb	[dxbc] Declare temp registers on demand ... And ignore dcl_temps. Needed to successfully compile some broken ENB shaders (this does work on Windows too). See #865.	2019-10-23 13:55:04 +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 5ee790a4a3. 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
Liam Middlebrook	2e83aae472	[dxbc] Print shader signatures at debug loglevel	2019-07-11 12:40:44 +02:00
Liam Middlebrook	ff4fa29304	[dxbc] Add string output function for DxbcRegMask	2019-07-11 12:40:44 +02:00
Liam Middlebrook	2164a44887	[dxbc] Add ostream operator for DxbcScalarType	2019-07-11 12:40:44 +02:00
Philip Rebohle	06d4e06d8a	[dxbc] Enable early discard on RADV/ACO ... Still can't enable on LLVM due to GPU hangs. The way we detect it may have to change in the future, but for now, this should do.	2019-07-08 16:30:56 +02:00
Philip Rebohle	58dcf77c08	[dxbc] Disable atomic counter optimization on old RADV versions ... Breaks TressFX in Tomb Raider 2013 for some reason, whereas this works fine on 19.1 with both LLVM 8.0 and 9.0-git.	2019-06-15 12:58:31 +02:00
