    Oct 27, 2016 · I have a code that uses SSSE3 intrinsic commands (note the triple S) and a runtime check whether to use it, therefore I assumed that the application should execute on CPUs without SSSE3 support. However, when using -mssse3 with -O1 optimization the compiler also inserts SSSE3 instructions which I didn't explicitly call, hence the program crashes.
