From Adam Green, regarding using -fno-delete-null-pointer-checks: "I would argue that on Cortex-M processors, it is more dangerous to not have it. The compiler can actually generate incorrect code because it is making an incorrect assumption (that reads from a NULL pointer will throw an exception.) The GCC for ARM developers should actually never enable the delete-null-pointer-checks optimization for Cortex-M processors. There is a comment in the GCC manual that indicates, "Some targets, especially embedded ones, disable this option [delete-null-pointer-checks] at all levels." Not having this flag is pretty risky on the current versions of GCC_ARM. Just to clarify, this flag doesn't enable an optimization...it disables an unsafe optimization." |
