Intel Graphics Compiler Update Adds 16-Bit Atomics For Tiger Lake, Other New Features

Written by Michael Larabel in Intel on 21 November 2019 at 01:11 AM EST. Add A Comment

Wednesday marked the v1.0.2878 update to Intel's "IGC" Graphics Compiler that is used by their graphics hardware compute stack.

Most notably this new IGC weekly-ish code update adds 16-bit atomics support to the Tiger Lake "Gen12" graphics. In addition to the 16-bit atomic operation support for Tiger Lake / Gen12, this release also extends SIMD media block read/write functionality, improved support for spill/fill intrinsics in presence of a stack call, support for the syncBuffer implicit argument, support for user-function annotations, and other changes. The C++ coding standard has also been updated to C++17.

More details on this IGC compiler update via GitHub.
