From 613a29affe272772dfe0c463d866fb0b8c1d42ee Mon Sep 17 00:00:00 2001 From: cheneym2 Date: Tue, 29 Oct 2024 16:42:18 -0400 Subject: Precompiled SPIR-V import support (#5048) * Precompiled SPIR-V import support Adds appropriate linkage and function declaration syntax for SPIR-V functions that are declared, to be imported from another SPIR-V module. Unlike DXIL, stripping the Slang IR for a function down to a declaration requires retaining a block of parameters, as the function declaration must be emitted to SPIR-V with the same parameters as a definition. Because that thwarts the logic in Slang to tell the difference between a declaration and definition, and explicit decoration is introduced to explicitly mark functions which need to be treated as declarations during emit phase.
