Shahbaz Youssefi c26011b8 2023-04-11T15:16:29 Vulkan: Make advanced blend alpha div workaround permanent This workaround turned out to affect pretty much every driver, and numerous GL implementations were found to work around it similarly to ANGLE. It seems like this workaround may only be necessary for colorburn and colordodge, but for now ANGLE applies it to all modes.

Shahbaz Youssefi 6f80f0f0 2022-08-06T02:29:19 Translator: Clean up the compile flag passing interface Historically, compile flags were sent to the translator as a bitmask. Recently, we were getting close to running out of bits. Additionally, direct-to-metal work had started to introduce constants to be passed to the translator, which were misplaced in ShBuiltInResources and Caps. Recent work on Pixel Local Storage adds even more constants, aggravating the situation. In this change, the interface to passing compile flags is reworked. A struct is passed (instead of a bitmask) that has one bit for each flag. This can be indefinitely extended. Additionally, the constants needed by metal and PLS are also placed in this struct. In turn, the backends can set these options directly, and don't have to hack them into Caps to further get hacked into ShBuiltInResources.

Mohan Maiya 9070e279 2022-06-30T09:35:59 Vulkan: Handle platforms that have imprecise float division issues Even when the dividend and divisor have the same value some platforms do not return 1.0f. We need to emit sepcial division code on such platforms.

Shahbaz Youssefi c5271e8e 2022-04-04T23:28:35 Vulkan: Emulate GL_KHR_blend_equation_advanced Based on a change by Brandon Schade <b.schade@samsung.com> In the translator, when advanced blend is enabled, an input attachment is added. Based on the listed advanced blend equations, emulation code is added that performs those equations' functions. The blend equation itself is passed through a driver uniform. Note that the advanced blend extension only allows a single output to use advanced blend, and that should be at location 0. In the Vulkan backend, when advanced blend is used, the driver uniform to select the equation is updated and normal blending is disabled.
