From 5f520819620642ecd2b070f96efa3007ac1f15a1 Mon Sep 17 00:00:00 2001 From: Kirill Yukhin Date: Thu, 13 Nov 2014 14:03:17 +0000 Subject: [PATCH 2/4] OpenMP 4.0 offloading to Intel MIC: liboffloadmic. * Makefile.def: Add liboffloadmic to target_modules. Make liboffloadmic depend on libgomp's configure, libstdc++ and libgcc. * Makefile.in: Regenerate. * configure: Regenerate. * configure.ac: Add liboffloadmic to target binaries. Restrict liboffloadmic for POSIX and i*86, and x86_64 architectures. Add liboffloadmic to noconfig list when C++ is not supported. config/ * target-posix: New file. libcilkrts/ * configure.tgt: Use config/target-posix. liboffloadmic/ Initial commit.
