message: Release notes for 1.13.0
diff: +=== v1.13.0 === (23 April 2020)
  +
  +An ISPC update, which graduates cross-compilation support to production and
  +has multiple code generation improvements and bug fixes. AVX512 targets may
  +get the biggest performance boost due to changed internal representation of
  +masks (we observed up to 5% speedups), and new switch '--opt=diable-zmm',
  +which disables using zmm registers in favour of ymm for avx512skx-i32x16 target.
  +All targets will definitely benefit from LLVM 10.0 backend used in this release.
  +
  +Here are the list of other changes:
  +
  +- new switch '--support-matrix' was added to display information about supported
  + cross-compilation targets, which are managed by '--target-os=<os>',
  + '--target=<ispc-target>', and '--arch=<arch>' switches.
  +- representation of 'bool' type in storage was changed to match C/C++ (i.e. one
  + 'bool' occupies one byte) for better interoperability.
  +- type aliases for unsigned types were added: 'uint8', 'uint16', 'uint32',
  + 'uint64', and 'uint'. To detect if these types are supported you can check if
  + ISPC_UINT_IS_DEFINED macro is defined.
  +- 'extract()'/'insert()' for boolean arguments, and 'abs()' for all integer and
  + FP types were added to standard library.
  +- FreeBSD was added to the list of supported target OSes, but it's not well
  + tested.
  +
  +Supported platforms in this release are below. Rows are hosts, columns are
  +targets. x86 and arm are both 32 and 64 bits, where appropriate.
  +
  + Windows | Linux | macOS | Android | iOS | PS4 | FreeBSD
  +Windows | x86 | x86, arm | x86 | x86, arm | | x86 | x86, arm
  +Linux | | x86, arm | x86 | x86, arm | | | x86, arm
  +macOS | | x86, arm | x86 | x86, arm | arm | | x86, arm
