Here combine simplifies the zero extension from
(lshiftrt:SI (ashift:SI (subreg:SI (reg:QI 138) 0)
(const_int 24 [0x18]))
(const_int 24 [0x18]))
to (ne:SI (subreg:SI (reg:QI 138)). From there it cannot derive

Another case, compile with -mcpu=arm1136jf-s -mthumb -O2

{
if (a = b || c d)
foo();
else
bar();
}
f:
