Thanks for the report. AVX has been out since early 2011 and Wikipedia claims that AVX support was added to OSX in version 10.6.8 in June 2011 and you seem to be using 10.8.0. I would presume that also means that the assembler supports it. So I'm going to guess that it's the "-mmacosx-version-min=10.5" parameter. Can you please try setting that to 10.6.8 and let me know the result? I don't know what the minimum system requirements for GCC 8 are going to be, but if it includes these older versions of OSX then I'll have to figure out how to cope with it in the libgcc build. Thanks, Daniel
