Hello Ian, Thanks for your reply. I have check out the source code from gimple-front-end branch, and build gimple1 successfully. However neither took the example of GimpleFrontEnd wiki nor *.gimple in gcc/testsuite/gimple.dg as input, gimple1 just check/parse but output nothing in *.s. My running script is as follows: $ gimple1 20120523-1.gimple I am wondering whether I misuse gimple1 or the project status is systax checking only. Thanks a lot 2012/11/30 Ian Lance Taylor <iant@xxxxxxxxxx>: > On Thu, Nov 29, 2012 at 10:52 AM, Lyu Mitnick <mitnick.lyu@xxxxxxxxx> wrote: >> >> 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.
