Hello all, I notice that there is a project Gimple FE - A Gimple Front End (http://gcc.gnu.org/wiki/GimpleFrontEnd). I have read the GCC document to find how to use. And I found the option, -fdump-tree-gimple, which can be used to output gimple. However I cannot find any option to read gimple in, and continues compiling. Would you mind to tell me how to do it? Thanks a lot
