- add new IShaderFormat API for separate preprocessing and compilation; backends can implement one or the other depending on the return value of SupportsIndependentPreprocessing - add support for executing preprocessing in the cook process prior to job submission and constructing job input hashes based on preprocessed source (and a subset of the environment used as compile inputs). controlled by a cvar for now and disabled by default - add a BaseShaderFormat class in ShaderCompilerCommon which implements common behaviour for output of debug data - note this function is only called for formats which support independent preprocessing, so is expected to be used only by formats which have been converted to use this API - add new cvars for output of some additional shader debug data - 1. a txt file containing the input hash a.k.a. job cache key 2. a text file containing all diagnostic messages (errors and warnings) for the job - minor change to how input hashes are constructed for pipeline jobs - sum hashes as 256-bit ints instead of adding to a buffer and re-hashing. faster and simpler, and also more collision resistant (sum of two well distributed hashes equally well distributed) #rb Jason.Nadro #rb Yuriy.ODonnell #preflight 64512c88c86798f650b953d3 [CL 25317218 by dan elksnitis in ue5-main branch]
