According to the people at Ada Core Technologies, that develop gnat, the GNU Ada compiler, all compliance tests has been done using the -O2 flag with the compiler. Thus that mode should be the most tested and reliable option for generating code. I have no problem believing that aerospace people distrust optimizers. They are in fact unlikely to trust anything before they have inspected the assembler output from the compiler. |
