Hello I have another question related to this. Lets suppose we have declared a local integer variable and we assigned some integer to it using gimple_build_assign statement (providing an ssa name). And after this, I want to modify the value of same variable. Should I create an other assignment statement or is there any other way to it? I have already tested it with creating an other assignment statement by providing the same ssa name but it gives me an error: hello.c:3:5: error: SSA_NAME_DEF_STMT is wrong Expected definition statement: b_4 = 1234; Actual definition statement: b_4 = 5555; hello.c:3:5: internal compiler error: verify_ssa failed Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Any help will be very useful. Regards Abdul On Tue, Jun 28, 2011 at 11:41 AM, Abdul Wahid Memon <engrwahidmemon@xxxxxxxxx> wrote: > Thanks alot.
