...le, LLVM's logic for merging isomorphic types causes two functions in different compilation units with identical function signatures to have different signatures in the resulting bitcode: =========================== $ cat demo-struct1.c struct foo { int x; }; struct bar { int x; }; struct foo *return_arg_1(struct foo *a, struct bar *b) { return a; } $ cat demo-struct2.c struct foo; struct bar; struct foo *return_arg_2(struct foo *a, struct bar *b) { return a; } $ ~/git/foreign/llvm-build/bin/clang -c -emit-llvm demo-struct1.c && ~/git/foreign/llvm-build/bin/clang -c -emit-llvm demo-struct2.c...
