If I don't specify any -march= or -mtune= options, what are the default architectures to generate code for and to tune for? Can I get the compiler to tell me this information? The documentation here doesn't seem to say anything about it: http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html I'm using "gcc (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1" targetting x86_64.
Hello! Try: gcc -Q --help=target 2>&1|grep "march\|mtune" Regards
