Capability System: Implicit capability upgrade warning/error (#4241)

2024-06-12T20:38:23+00:00

* capability upgrade warning/error adjusted implementation + tests to support a warning/error if capabilities are implicitly upgraded and test accordingly. * add glsl profile caps * add GLSL and HLSL capabilities to the associated capability * syntax error in capdef * only error if user explicitly enables capabilities 1. changed testing infrastructure to not set a `profile` explicitly, 2. Added tests to be sure this works as intended with user API and with slangc command line * Change capability atom definitions and how Slang manages them to fix errors 1. most `glsl_spirv` version atoms have been removed from `.capdef`, instead we will translate `spirv` version atoms into `glsl_spirv` since there is no point in writing the same code twice in `.capdef` files to define `spirv` versions. 2. add spirv version, and hlsl sm version (and equivlent) capability dependencies 3. removed some stage requirments which were set on objects, keep the wrapper capabilities. I am keeping the wrapper capabilities since I am unaware on if there are stage limitations (spec says code in practice does not work). * check internal version instead of version profile (_spirv_1_5 vs. spirv_1_5) * remove unused OpCapability. adjust SPIRV version'ing again for glsl_spirv * apply workaround for glslang bug with rayquery usage * ensure capabilities targetted by a profile and added together by a user are valid * remove additions to `spirv_1_*` wrapper * spirv_* -> glsl_spirv fix * fix bug where incompatable profiles would cause invalid target caps * try to avoid joining invalid capabilities * fix the warning/error & printing * run through tests to fix capability system and test mistakes many mistakes were mesh shaders doing `-profile glsl_450+spirv_1_4`. This is not allowed for a few reasons 1. the test tooling does not handle arguments the same as `slangc` 2. glsl_450 core profile does not support mesh shaders, nor does spirv_1_4. sm_6_5 does work in this senario * set some sm_4_1 intrinsics to sm_4_0 * replace `GLSL_` defs with `glsl_` * swap the unsupported render-test syntax for working syntax * set d3d11/d3d12 profile defaults this is required since sm version changes compiled code & behavior * adjusted nvapi capabilities with atomics + d3d11 set to use sm_5_0 as per default * cleanup * address review * incorrect styling * change `bitscanForward` to work as intended on 32 bit targets --------- Co-authored-by: Yong He
