I was wondering if there\'s a way to disable predication in gcc/g++. When I get the object dump of my code, I don\'t want there to be any CMOV, CCMP, etc instructions in it.

    I ran into that problem before and in my case the solution was to disable if-conversion. You can use the compilation flags:

    -fno-if-conversion -fno-if-conversion2
