Expand description

Certain target environments impose additional restrictions on SPIR-V, so it’s often necessary to specify which one applies. Universal_* implies an environment-agnostic SPIR-V.

When an API method needs to derive a SPIR-V version from a target environment the method will choose the highest version of SPIR-V supported by the target environment. Examples: SPV_ENV_VULKAN_1_0 -> SPIR-V 1.0 SPV_ENV_VULKAN_1_1 -> SPIR-V 1.3 SPV_ENV_VULKAN_1_1_SPIRV_1_4 -> SPIR-V 1.4 SPV_ENV_VULKAN_1_2 -> SPIR-V 1.5

Consult the description of API entry points for specific rules.
