ispc/ispc v1.12.0

v1.12.0 (15 August 2019)

on GitHub

This ISPC update includes experimental cross OS compilation support, ARM and AARCH64
support and a bunch of language features and stability fixes.

Here are the details:

• ISPC is now a cross OS compiler - You can build ISPC programs for Windows, Linux,
  macOS, iOS, Android and PS4 targets from Windows, Linux and macOS hosts.
• ARM and AARCH64 support has been enabled for ISPC. ARM support currently exists for
  neon-i32x4, neon-i8x16 and neon-i16x8 targets. AARCH64 is supported for neon-i32x4
  as well as for a new "double-pumped" 8-wide target: neon-i32x8.
• A new 128-bit AVX2 target (avx2-i32x4) was added.
• Added a CPU definition for Ice Lake client CPUs (--cpu=icl). Note that there is no
  special target for new instructions in Ice Lake flavor of AVX512 yet. For now, You
  can use SKX targets (avx512skx-i32x8 and avx512skx-i32x16) with --cpu=icl.
• Removed the generic targets for KNC and KNL, so ISPC does not have KNC support anymore.
  KNL is still supported through native target (avx512knl-i32x16).
• Removed AVX1.1 (IvyBridge) targets (use AVX1 targets instead).
• Introduced new language features:
  • noinline function qualifier.
  • rsqrt_fast() and rcp_fast() functions.
  • Static initialization for varying.
• A new command line option --emit-llvm-text was added to dump LLVM IR in text format.

An ISPC top-of-trunk build is now available in the Compiler Explorer

The release is based on a patched LLVM 8.0.0 backend.
