@aaron.ballman I am both grateful and sad that I don't possess the same macro creativity as you do. :)
(I'm also sad that the various clang APIs aren't as well documented as I hoped. The current solution works well, but it took a while and a bit of consultation with some other llvm'ers to get it right.)
Comment at: test/clang-tidy/abseil-duration-comparison.cpp:146
+#define VALUE_IF_2(e) (e)
+#define VALUE_IF(v, e, type) (v ? VALUE_IF_2(absl::To##type##Seconds(e)) : 0)
+ int a3 = VALUE_IF(1, d1, Double);

This also doesn't transform.
