[Bug tree-optimization/111801] [14 Regression] Missed Dead Code Elimination since r14-4141-gbf6b107e2a3
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=111801 --- Comment #2 from Jeffrey A. Law --- Interestingly enough this is picked up at -O3. Looks like PRE does a better job and the result is easier to discover the range for first operand of the controlling conditional.

[Bug tree-optimization/110931] [14 Regression] Dead Code Elimination Regression since r14-2890-gcc2003cd875
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110931 --- Comment #5 from Jeffrey A. Law --- One could also look at this as a failure to propagate. l.0_1 = l; t_4 = (short int) l.0_1; if (t_4 == 0) goto ; [50.00%] else goto ; [50.00%] We ought to be able to propagate l.0_1 into t
