Unity 2018.2 Released

New version of popular cross platform engine brings cool new features and updates
11 July 2018   1945

The developers published an update of the game engine Unity. According to the team, the new version is mostly devoted to improvements in rendering and mobile development.

The update improves and optimizes the performance of the two components of the Scriptable Render Pipeline: Lightweight Render Pipeline (LWRP) and High Definition Render Pipeline (HDRP) tools.

  • LWRP controls the loading and storage of tiles, optimizing the memory of the device, so that high performance is achieved even on weak hardware and in high-load applications in virtual reality;
  • HDRP includes various improvements in image quality and visual effects to create cinematic images on powerful platforms such as PCs and game consoles.

Both functions are still in early access and are not recommended for commercial use.

In addition, Shader Graph - a tool for visual creation of shaders without programming skills - now supports both components of Scriptable Render Pipeline. It also received an improved interface for interaction and several new features.

With the new version of the engine, users will be able to download files with .java extensions into the project without the need to collect separate libraries in Android Studio. They will be recognized as Unity plug-ins and compiled into an executable file. Also engine now officially supports Android-applications with 64-bit architecture, which means projects can use more than 4 GB of RAM.

In addition, developers have added the ability to debug managed code on iOS, Android, Windows, macOS, UWP and PS4.

LLVM 10.0.0 to be Released

New version of the popular development toolkit brings, among other things, support for the C++ Concepts
26 March 2020   915

After six months of development, the release of the LLVM 10.0 project, a GCC-compatible toolkit (compilers, optimizers, and code generators), compiling programs into an intermediate bitcode of RISC-like virtual instructions (a low-level virtual machine with a multi-level optimization system), is presented. The generated pseudo-code can be converted using the JIT compiler into machine instructions directly at the time of program execution.

Among the new features of LLVM 10.0, there are support for C ++ Concepts (C ++ Concepts), termination of the launch of Clang in the form of a separate process, support for CFG checks (control flow guard) for Windows, and support for new CPU features.

The main innovations of LLVM 10.0:

  • New interprocedural optimizations and analyzers have been added to the Attributor framework. The prediction of the state of 19 different attributes, including 12 attributes of 12 LLVM IR and 7 abstract attributes such as liveness, is provided.
  • New built-in compiler matrix mathematical functions (Intrinsics) have been added, which, when compiled, are replaced by effective vector instructions.
  • Numerous improvements to the backends for the X86, AArch64, ARM, SystemZ, MIPS, AMDGPU, and PowerPC architectures. Added support for Cortex-A65, Cortex-A65AE, Neoverse E1 and Neoverse N1 CPUs. For ARMv8.1-M, ​​the code generation process has been optimized (for example, support for loops with minimal overhead has appeared) and support for auto-vectorization using the MVE extension has been added. Improved support for CPU MIPS Octeon. PowerPC includes vectorization of mathematical routines using the MASSV (Mathematical Acceleration SubSystem) library, improved code generation, and optimized memory access from loops. For x86, the processing of vector types v2i32, v4i16, v2i16, v8i8, v4i8 and v2i8 has been changed.
  • Improved code generator for WebAssembly. Added support for TLS (Thread-Local Storage) and atomic.fence instructions. Significantly expanded support for SIMD. WebAssembly object files added the ability to use function signatures with multiple values.
  • When processing cycles, the MemorySSA analyzer is used to determine the dependencies between different memory operations. MemorySSA can reduce compilation and execution time, or can be used instead of AliasSetTracker without sacrificing performance.
  • The LLDB debugger has significantly improved support for the DWARF v5 format. Improved build support with MinGW and added the initial ability to debug Windows executable files for ARM and ARM64 architectures. Added descriptions of options offered when autocompleting input by pressing tabs.
  • Enhanced LLD Linker Features. Improved support for the ELF format, including full compatibility of glob templates with the GNU linker, added support for the compressed debug sections ".zdebug", added the PT_GNU_PROPERTY property to determine the .note.gnu.property section (can be used in future Linux kernels), implemented modes "-z noseparate-code", "-z separate-code" and "-z separate-loadable-segments". Improved support for MinGW and WebAssembly.
