About the effect of "O0" on inlining into a function
Hello Iain Sandoe wrote: If I declare a function __attribute__((noipa, optimize (“-O0”))), I was kinda expecting that it would not be optimized at all .. however it does not seem to prevent functions called by it from being inlined into its body .. I would suggest coding your GCC plugin to add such a behavior.
