Hi, I am trying to insert an assignment statement at the beginning of the basic-block in a pass that I added after the gimple pass. I had referred to the following post : http://gcc.gnu.org/ml/gcc-help/2011-05/msg00347.html I used the API gsi_insert_before to do this. However, everytime I use this API , I get the following build error In function ‘gimple_seq_node_d* gimple_seq_first(const_gimple_seq)’: error: non-trivial conversion at assignment char <unnamed type> # .MEM_7 = VDEF <.MEM_6(D)> aa_glob = 1; gccwk.c:99:2: internal compiler error: verify_gimple failed Please submit a full bug report, with preprocessed source if appropriate. I tried to search for the above error but did not find anything useful I am using GCC 4.7.0 My code is: > tree var_decl; > gimple_stmt_iterator si; > tree boolean_const; > gimple assign; > basic_block bb_start = ENTRY_BLOCK_PTR->next_bb; > gimple_stmt_iterator gsi = gsi_start_bb(bb_start); > > // Create a global variable > var_decl = build_decl(UNKNOWN_LOCATION, VAR_DECL, get_identifier("aa_glob"),char_type_node); > TREE_STATIC(var_decl) = 1; > rest_of_decl_compilation(var_decl,1,0); > > boolean_type_node = make_unsigned_type (BOOL_TYPE_SIZE); > TREE_SET_CODE (boolean_type_node, BOOLEAN_TYPE); > boolean_const = build_int_cst(boolean_type_node, 1); > > // Build the assignment expression > assign = gimple_build_assign(var_decl,boolean_const); > > // Verify the assignment statement by printing > print_gimple_stmt(stderr,assign,0,0); <-------------------------- At this point I am able to see the assignment statement printed on console correctly > > > gsi_insert_before(&gsi, assign, GSI_SAME_STMT); <-------------- I get the above error only when I try to add this line of code > Is my usage of the API correct? Thank you.
