[PATCH] D50670: Implementation of nested loops in cxx_loop_proto

[Matt Morehouse via Phabricator via cfe-commits]

morehouse added inline comments.


================
Comment at: clang/tools/clang-fuzzer/proto-to-cxx/loop_proto_to_cxx.cpp:124
+void SingleLoopToString(std::ostream &os, const LoopFunction &x) {
+  inner_loop = false;
+  os << "void foo(int *a, int *b, int *__restrict__ c, size_t s) {\n"
----------------
Why do we need to set `inner_loop` from different functions?

Again, using the global like this is just too easy to screw up.  I'd like to see it default to false and then have a scoped wrapper that sets it to true only for the duration necessary.


================
Comment at: clang/tools/clang-fuzzer/proto-to-llvm/loop_proto_to_llvm.cpp:137
+     << x.outer_statements();
+  inner_loop = true;
+  os << "%o_ct_new = add i64 %outer_ct, 1\n"
----------------
Same comment as above.  I'm getting confused trying to understand what `inner_loop` is set to at any given point.
