A major new version of ISPC, which introduces experimental support for NVPTX
target, brings numerous improvements to our KNC (Xeon Phi) support, introduces
debugging support on Windows and fixes several bugs. We also ship experimental
build for Sony PlayStation4 target in this release. Binaries for all platforms
are based on LLVM 3.5.
Note that MacOS binaries are build for MacOS 10.9 Mavericks. Linux binaries are
compatible with kernel 2.6.32 (ok for RHEL6) and later.
More details:
-
Experimental NVPTX support is available for users of our binary distribution
on Linux only at the moment. MacOS and Windows users willing to experiment
with this target are welcome to build it from source. Note that GPU imposes
some limitation on ISPC language, which are discussed in corresponding section
of ISPC User's Guide. Implementation of NVPTX support was done by our
contributor Evghenii Gaburov. -
KNC support was greatly extended in
knc.hheader file. Beyond new features
there are stability fixes and changes for icc 15.0 compatibility. Stdlib
prefetch functions were improved to map to KNC vector prefetches. -
PS4 experimental build is Windows to PS4 cross compiler, which disables arch
and cpu selection (which are preset to PS4 hardware). -
Debug info support on Windows (compatible with VS2010, VS2012 and VS2013).
-
Critical bug fix, which caused code generation for incorrect target, despite
explicit target switches, under some conditions. -
Stability fix of the bug, which caused
print()function to execute under
all-off mask under some conditions.
