Fixed Issues / Improvements

• Added support for non-constant parameter for llvm.genx.GenISA.memoryfence and llvm.genx.GenISA.typedmemoryfence instructions,
• Added analysis of stateless memory load/store,
• Added env. variable for SPIRVDLL path,
• Added new regkey to disable DispatchAlongY for HW IDs,
• Avoiding passing large composite values when localizing globals by value,
• Compile time improvements in IGC debug info,
• Considering constant EM lowered in SIMDCFConformance,
• Convert pseudo-or/and/xor to Gen or/and/xor if flag size is smaller than inst SIMD size,
• Enabled vector-backend to take LLVM bitcode input,
• Debug info should be generated automatically when run under gdb,
• Enabled RNE by default for IEEE float-divide,
• Enabled SIMD32 subgroup shuffles,
• Fixed GRF register checking in linear scan RA,
• Fixed parsing of switchjmp for vISA assembly,
• Fixed SPIRV reader constructing reference type debug metadata,
• Initial support for interprocedural TPM pass,
• Introduction of new entry in IGC constant folder for IBFE,
• Lower genx.*mul.sat intrinsics since integer mul.sat is not supported,
• Made improvements in ranges emitted to .debug ranges section,
• Negative modifiers are no longer baled if applied on unsigned integer,
• Open sourced IMF LA; added common header,
• Refactored Int64b support,
• Removed indirection for input arguments,
• Removed legacy inter-procedural analysis code for RA,
• Removed support for -cl-feature,
• Rewritten CM adaptor library,
• Simplifying building workspace/instruction,
• Skip CS simd32 if it is a retry to speed up compile time,
• Skip invalid warning in ShaderOverride mode,
• Unify the stack call functions for both global RA and linear scan RA,
• Vector compiler:
  • Backend should not use reserved BTI indexes for debuggable kernels,
  • i64 emulation should convert partial predicates to icmp,
  • Refactored TransformNode CMABI.
• Changes in preparation of LLVM 11 upgrade,
