It's unclear why these tests fail. All of them have loops where iterations depend on execution state.

For parity.c
, the problem seems to be in the following snippet of cex
%.02.i.lcssa = phi i8 [ 0, %entry ], [ 1, %.lr.ph ]
%.02.i.lcssa (1:bv(8))
%_4 = lshr i32 %_0, 1
%_4 (4096:bv(32))
%_5 = xor i32 %_4, %_0
%_5 (12288:bv(32))
%_6 = lshr i32 %_5, 2
%_6 (3072:bv(32))
%_7 = xor i32 %_6, %_5
%_7 (3072:bv(32))
%_8 = and i32 %_7, 286331153
%_7
should evaluate to 15360
but it evals to 3072
