I would have preferred something a bit more like Checkout http://esolangs.org/wiki/Checkout instead, but what you have still can be worked. Compilers from ARB assembly language or whatever else you want can then also be written to target it. Is there a compiler from ARB assembly language into SPIR-V?[04:29:47] <slime> no[04:30:03] <slime> ARB assembly language has not been used in new programs for many many years[04:31:04] <zzo38> That isn't quite true, but it is OK anyways, because if it is needed then I can write such a program.[04:31:49] <|3b|> how about "there hasn't been any point in using ARB assembly in many years"? :)[04:31:58] <slime> it has not been used in shipping software that a non-insignificant number of end-users run[04:32:20] <slime> and also there's no point to it anymore, yeah[04:32:21] <zzo38> Because there are no flow-controls, I think it should be easy to convert into SSA format.[04:32:39] <|3b|> (sort of like how that checkout says asm/machine language matches old hardware, same with ARB asm)[04:33:15] <zzo38> Yes, that is why I think Checkout would be better than ARB assembly language.[04:33:25] <|3b|> if you want something asm-like, just use spirv directly (or write a nicer layer on top of it to handle stuff like allocating temps)[04:34:09] <zzo38> Yes, that is good, if the program is only for Vulkan and not for OpenGL, then I probably would do that.[04:34:52] * |3b| notes there is a GL extension to use spirv, not sure how widely implemented it is though[04:34:54] <slime> you can use khronos' SPIRV-cross tool to compile spirv to glsl[04:35:05] <slime> (and spirv to MetalSL, and HLSL)[04:35:12] <slime> https://github.com/KhronosGroup/SPIRV-Cross[04:36:00] <zzo38> slime: O, so then you can compile the SPIR-V program to be use with not only Vulkan but also any implementation that support GLSL, MetalSL, and/or HLSL too; that is good.[04:37:34] <zzo38> I did also think of though to target ARB assembly language, and perhaps also target Checkout, but then if I write a layer on top of SPIR-V, it can be made to directly be able to target ARB assembly language as well as Checkout, and then there is no need to target GLSL because the program to do that is already exist![04:38:25] <zzo38> (Of course it may not target Checkout until the preprocessor is defined, anyways)[04:41:05] <zzo38> And I think I read also somewhere a compiler from SPIR-V to LLVM (and also other way around), so that then completes it.[04:50:01] <zzo38> Two of my programs (ff-glfrag and SDLTERM) use ARB assembly language, although it is possible that later implementations of the API of SDLTERM can be used with Vulkan and others too.[04:50:02] *** zzo38 <zzo38!~zzo38@24-207-44-58.eastlink.ca> has left ##vulkan[04:50:26] *** herbmillerjr
