It turned out that the GCC compiler generates assembly files (.s) using its own dialect; Clang abides by the Intel official assembly syntax and both are partly incompatible. So there is no real way out this conundrum: using Clang as an assembler for GCC .s file will not work for anything else that the simplest of simple C files. To wrap up: abandon AVX with gcc-mp-… compilers, and don’t think about __asm__ () with GNU dialect assembly for Clang compiling… Vincent _______________________________________________ macports-dev mailing list [email protected] http://lists.macosforge.org/mailman/listinfo/macports-dev
