[PATCH] D84371: [DFSan] Add efficient fast16labels instrumentation mode.

[Kostya Serebryany via Phabricator via llvm-commits]

kcc added inline comments.


================
Comment at: compiler-rt/lib/dfsan/dfsan.cpp:173
+// Configures the DFSan runtime to use fast16labels mode.
+extern "C" SANITIZER_INTERFACE_ATTRIBUTE void dfsan_use_fast16labels() {
+  use_fast16labels = true;
----------------
I wonder if we can get away w/o these flags.
Just assume that fast16mode works only when the fast16mode instrumentation is enabled. 
(remember, fast16mode is currently experimental, we are free to change its behavior)
