This option only has an effect if there are modules that were precompiled to the target IR using precompileForTarget(). Until now, the default behavior for SPIR-V was to use deferred linking, and the default behavior for DXIL was to use immediate/internal linking in Slang. This change only affects the SPIR-V behavior such that both deferred and non-deferred linking is supported based on the new option. To support the non-deferred option, Slang will internally call into SPIRV-Tools-link to reconstitute a complete SPIR-V shader program when necessary (due to modules having been precompiled to target IR). Otherwise, if SkipDownstreamLinking is enabled, the shader returned by e.g. getTargetCode() or getEntryPointCode() may have import linkage to the SPIR-V embedded in the constituent modules.

This enabled a bunch of convenient includes, but might lead to confusing behavior for anyone including slang. Not to mention differences including it from an install vs source.

Removed extra helper function left over from old cache implementation * Reverted performance change to generate contents hashes when modules are being loaded as this code path is not always followed; Contents hashing now uses a combination of hashing and checking the last modified time for all file dependencies, only reading in and hashing the contents of all files if the last modified hash does not match * Added handling to Module::updateContentsBasedHash for file dependencies which are not from a physical source file on disk;

Added test for cache eviction policy (which currently does not pass) * Restructured main if block in getEntryPointCodeFromShaderCache; Post-rebase cleanup * undo local testing only change * Fixed issues causing shader cache tests to fail * Edited gfx.slang to reflect structural changes to IDevice::Desc and to include ShaderCacheDesc; Modified how the cache is reading in the file from disk; Added a check to the cache eviction policy test that checks for correct order of entries in the cache as well as eight total expected output files for D3D12 and Vulkan * Removed line in gfx-unit-test.cpp for local testing * Edited .gitignore to ignore all shaders automatically generated by the shader cache tests and removed the test shaders that were previously added; Review changes, most notably with an overhaul of how the cache eviction policy test handles checking order of entries * Ran premake; Removed local testing specific line (again) * Removed expected comparison files from earlier commit; Ran premake * Edited premake5.lua to also ignore the auto-generated shader files from specific shader cache tests * Fixed weird indent in premake5.lua
