I've been working on a patch that fixes the original reported problem by adding
a little logic to tree-ssa-reassoc.c to make it look for places where it can
use combine_comparisons. Note that this test case does not involve an "if" or
require any particular CFA, just straightforward expression simplification. My
sense is that the test cases that do involve "if"s and/or require flow analysis
are in fact different bugs that require different fixes. (In fact, 28691 looks
more like an RTL-level optimization to me, maybe even backend-specific.) So,
is it really useful to lump them all together as duplicates for tracking
purposes? Or am I totally barking up the wrong tree here?
