--
-- == Description
--
-- This extension adds a way to query certain information about a compiled
-- shader which is part of a pipeline. This information may include shader
-- disassembly, shader binary and various statistics about a shader’s
-- resource usage.
--
-- While this extension provides a mechanism for extracting this
-- information, the details regarding the contents or format of this
-- information are not specified by this extension and may be provided by
-- the vendor externally.
--
-- Furthermore, all information types are optionally supported, and users
-- should not assume every implementation supports querying every type of
-- information.
--
-- == New Commands
--
-- -   'getShaderInfoAMD'
--
-- == New Structures
--
-- -   'ShaderResourceUsageAMD'
--
-- -   'ShaderStatisticsInfoAMD'
--
-- == New Enums
--
-- -   'ShaderInfoTypeAMD'
--
-- == New Enum Constants
--
-- -   'AMD_SHADER_INFO_EXTENSION_NAME'
--
-- -   'AMD_SHADER_INFO_SPEC_VERSION'
--
-- == Examples
--
-- This example extracts the register usage of a fragment shader within a
-- particular graphics pipeline:
--
-- > extern VkDevice device;
-- > extern VkPipeline gfxPipeline;
-- >
-- > PFN_vkGetShaderInfoAMD pfnGetShaderInfoAMD = (PFN_vkGetShaderInfoAMD)vkGetDeviceProcAddr(
-- >     device, "vkGetShaderInfoAMD");
-- >
-- > VkShaderStatisticsInfoAMD statistics = {};
-- >
-- > size_t dataSize = sizeof(statistics);
-- >
-- > if (pfnGetShaderInfoAMD(device,
-- >     gfxPipeline,
-- >     VK_SHADER_STAGE_FRAGMENT_BIT,
-- >     VK_SHADER_INFO_TYPE_STATISTICS_AMD,
-- >     &dataSize,
-- >     &statistics) == VK_SUCCESS)
-- > {
-- >     printf("VGPR usage: %d\n", statistics.resourceUsage.numUsedVgprs);
-- >     printf("SGPR usage: %d\n", statistics.resourceUsage.numUsedSgprs);
-- > }
--
-- The following example continues the previous example by subsequently
-- attempting to query and print shader disassembly about the fragment
-- shader:
--
-- > // Query disassembly size (if available)
-- > if (pfnGetShaderInfoAMD(device,
-- >     gfxPipeline,
-- >     VK_SHADER_STAGE_FRAGMENT_BIT,
-- >     VK_SHADER_INFO_TYPE_DISASSEMBLY_AMD,
-- >     &dataSize,
-- >     nullptr) == VK_SUCCESS)
-- > {
-- >     printf("Fragment shader disassembly:\n");
-- >
-- >     void* disassembly = malloc(dataSize);
-- >
-- >     // Query disassembly and print
-- >     if (pfnGetShaderInfoAMD(device,
-- >         gfxPipeline,
-- >         VK_SHADER_STAGE_FRAGMENT_BIT,
-- >         VK_SHADER_INFO_TYPE_DISASSEMBLY_AMD,
-- >         &dataSize,
-- >         disassembly) == VK_SUCCESS)
-- >     {
-- >         printf((char*)disassembly);
-- >     }
-- >
-- >     free(disassembly);
-- > }
