IGC v2.28.4

Known issues

• IGC v2.27.10 release packages have been built with opaque pointers, however, local build sets IGC to typed pointers by default; this release still has this issue,
• to enable opaque pointers in local builds pass the CMake option -DIGC_OPTION__API_ENABLE_OPAQUE_POINTERS=ON
• the issue will be resolved in v2.29.x (20f3ffd)

IGC v2.20.5

Known issues

In this release we observe 5-10% regressions in the following scenarios specific to the Arrow Lake platform:

Ze_peak_int16,  ARL-S
Ze_peak_int2, ARL_H
Cl_peak_int, ARL_H
Cl_peak_int2, ARL_H

The regression is expected to be contained to benchmarks measuring peak performance.
Real-world scenarios are effectively non-affected.

IGC v2.19.2

Prerelease note

This is a prerelease with no full production quality guarantees.
It was validated with compute runtime development branch.
Only experimental use is recommended.

Fixed Issues / Improvements

• Production packages have switched to LLVM 16
• Production configuration uses LLVM typed pointers; opaque pointers support is WIP
  • To enable typed pointers use the CMake option: IGC_OPTION__API_ENABLE_OPAQUE_POINTERS=OFF

IGC v2.18.5

Fixed Issues / Improvements

- Production packages have switched to LLVM 16
- Production configuration uses LLVM typed pointers; opaque pointers support is WIP
- To enable typed pointers use the CMake option: IGC_OPTION__API_ENABLE_OPAQUE_POINTERS=OFF

Due to an error IGC 2.18 was mistakenly released as built with LLVM 16. This is incorrect, IGC 2.18 uses LLVM 15.
IGC 2.19 will be the first release to use LLVM 16 with typed pointers.
