Hi, I'm considering how to escape the unnecessary re-optimization in automatic parallelization.
e.g. in a source code the function fun() one loop is considered can_be_parallel by Graphite pass, and in pass tree-parloop.c, will call the code generation part for this loop and generate newly created fun.loop_f0(), note that fun.loop_f0 is a function that has some omp directive added on optimized function fun()'s loop (It has been optimized by the passes before tree-parloop.c), and to my observation, the newly created function fun.loop_f0 will be passed through the first pass again (Is this statement corret?). So my question is, 1. Is this necessary/correct if we want to escape the re-optimization for the first few passes before tree-parloop.c and continue the optimization passes after it for the function fun.loop_f0, there must be compile time savings if we do this in my opinion. 2. How could I do if we want to do this. I'm not familiar with the mechanism that how passes works, it'll be appriciate if someone can tell me more. Thanks, Li
