igc-1.0.4479

Fixed Issues / Improvements

• Fail compilation with error message instead of crash if we can't find sampler argument or inline/global sampler.
• DWARF debugger location expressions fixes.
• Remove redundant LICM pass.
• Enable timestats through regkey.
• extend the MarkReadOnlyPass to mark loads with constant address space with invariant.load.
• Adding metadata for computedDepthMode.
• Enable vISA instruction splitting pass.
• Open-sourcing CM FE related parts of driver.
• Fix system LLVM handling in VC.
• update integer splitter api in VectorCompiler.
• Improve lowering of ord/unord fcmp.
• Emask calculation correcting by remove the write enable and using right data types.
• Basic block where flow control partially joins should also be treated as divergent.
• Limit total thread payload size to 96 GRFs.
• Tighten up vISA assembly syntax: do not allow missing regions for general operands, do not allow two offsets for address operands.
• Fixed operations with overflow.
• Prevent tracking of images and samplers from falling into infinite loop.
• Fix lowpc/highpc for subroutines in debug info.
• Make Dst operand's subreg offset immutable.
• Get rid of unnecessary MOVS.
• Check for undefined predicate variables when parsing vISA assembly.
• Removing the dst/src overlap checking after augmentation.
• ZEBinary: add kernel symbol.
• Fix TPM's replaceGatherPrivate.
• Add ZEAutoTool.
• Report parser error for vISA inline assembly in releaseInternal build.
• ZEBinaryBuilder: Fix packed_local_ids size to 6 instead of 12.
• DWARF debugger location expressions fixes.
• Avoid multiple metadata regenerating in AggregateArguments pass.
• Refactor for stack call functions. Combine code for caller/callee stack load/store.
• Fix shuffleVector lowering in legalization pass.
