Tobias PS: Is it correct that the current implementation only supports ABI 0.9 of Oct 2010 and not ABI 1.1 of Jul 2011? (Current is 1.2 of Sep 2013, cf. http://www.cilkplus.org/download#open-specification) The ABI version 0.9 is taken from gcc/doc/invoke.texi [The library has CILKLIB1.02.] Index: changes.html =================================================================== RCS file: /cvs/gcc/wwwdocs/htdocs/gcc-4.9/changes.html,v retrieving revision 1.61 diff -p -r1.61 changes.html *** changes.html 8 Mar 2014 18:09:45 -0000 1.61 --- changes.html 8 Mar 2014 18:15:06 -0000 *************** *** 157,162 **** --- 157,167 ---- loop-carried dependencies which would prevent concurrent execution of consecutive iterations using SIMD (single instruction multiple data) instructions. + +
