I'm trying to generate calls to "free" on the fly at ipa time.
I've tried several things (given below) but they both fail
in expand_call_inline in tree-inline.c on this gcc_checking_assert:
cg_edge = id->dst_node->get_edge (stmt);
gcc_checking_assert (cg_edge);
Now, I've tried using the built in free via:
tree fndecl_free = builtin_decl_explicit( BUILT_IN_FREE);
// Note to_free is set between here and the call by an assign
tree to_free =
make_temp_ssa_name( reorg_pointer_type, NULL, "malloc_to_free");
.
.
gcall *free_call = gimple_build_call( fndecl_free, 1, to_free);
or building the fndecl from scrath:
tree fntype = build_function_type ( free_return_type, param_type_list);
tree fnname = get_identifier ( "free");
tree fndecl_free =
build_decl ( input_location, FUNCTION_DECL, fnname, fntype);
gcall *free_call = gimple_build_call( fndecl_free, 1, to_free);
Note, I was able to get something similar to work for "malloc" by
using the fndecl I extracted from an existing malloc call.
Your advice on how to build a fndecl that doesn't have this
problem is appreciated.
Thanks,
Gary Oblock
