Hi, I could be wrong, but it would be very weird if the compiler generated co-processor code from C sources. Those instructions were only created to cope with "unknown extensions", even though they god used by a number of known ones. Unless, of course, they were in inline assembly, in which case it's not really the compiler's output, but it will "come from C code". It should be pretty easy to grep for asm/cp15 inline asm (or asm files) in a source three, though, so you can know if a project will emit them or not without looking at the compiler. cheers, --renato _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain
