From 939a7e9a5c0a74fb2fabb00b61ba6375e22bf1a6 Mon Sep 17 00:00:00 2001 From: Pierre Moreau Date: Sat, 10 Feb 2018 21:40:10 +0100 Subject: clover/spirv: Add functions for validating SPIR-V binaries MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Changes since: * v12: - remove autotools (Karol Herbst) - Remove the callback in format_validation_msg. (Francisco Jerez) - Removed is_binary_spirv. (Francisco Jerez) - Pass a string reference to is_valid_spirv instead of the notification callback. (Francisco Jerez) * v11: Fix compilation error introduced in v11. * v10: - Reuse format_validation_msg in is_valid_spirv. - Remove LVL2STR macro in format_validation_msg. * v9: Add `clover_cpp_std` to the overrides of the `libclspirv` target in Meson. * v7: Add DEFINES to libclspirv and libclover, in autotools, as they would otherwise never know whether CLOVER_ALLOW_SPIRV has been defined (Dave Airlie) * v6: Update the dependency name (meson) and the libs variable (Makefile) due to the replacement of llvm-spirv to the new official SPIRV-LLVM-Translator. * v5: Changed to match the updated “clover/llvm: Allow translating from SPIR-V to LLVM IR” in the v6.
