+Subject: [PATCH] ipa: fix bit CPP when combined with IPA bit CP
+
+As mentioned in the PR, let's consider the following example:
+
+int
+__attribute__((noinline))
+foo(int arg)
+{
+  if (arg == 3)
+    return 1;
+  if (arg == 4)
+    return 123;
+
+  __builtin_unreachable ();
+}
+
+during WPA we find all calls of the function
+(yes the call with value 5 is UBSAN):
+
+  Node: foo/0:
+    param [0]: 5 [loc_time: 4, loc_size: 2, prop_time: 0, prop_size: 0]
+               3 [loc_time: 3, loc_size: 3, prop_time: 0, prop_size: 0]
+         ctxs: VARIABLE
+         Bits: value = 0x5, mask = 0x6
+
+in LTRANS we have the following VRP info:
+
+  # RANGE [3, 3] NONZERO 3
+
+when we AND masks in get_default_value we end up with 6 & 3 = 2 (0x010).
+That means the only second (least significant bit) is unknown and
+value (5 = 0x101) & ~mask gives us either 7 (0x111) or 5 (0x101).
+
+That's why if (arg_2(D) == 3) gets optimized to false.
+
+gcc/ChangeLog:
+
+	PR ipa/96482
+	* ipa-cp.c (ipcp_bits_lattice::meet_with_1): Drop value bits
+	for bits that are unknown.
+	(ipcp_bits_lattice::set_to_constant): Likewise.
+	* tree-ssa-ccp.c (get_default_value): Add sanity check that
+	IPA CP bit info has all bits set to zero in bits that
+	are unknown.
+
+gcc/testsuite/ChangeLog:
+
+	PR ipa/96482
+	* gcc.dg/ipa/pr96482.c: New test.
