+
+  define i1 @test() {
+  entry:
----------------
Defining this function with `zeroext` return value attribute, like `test/CodeGen/AArch64/arm64-xaluo.ll` does for instance, seems to fix the problem w/ no changes to the compiler.


================
Comment at: test/CodeGen/AArch64/GlobalISel/legalize-bool.mir:29
+    %0:_(s1) = G_CONSTANT i1 true
+    %1:_(s32) = G_ANYEXT %0(s1)
+    $w0 = COPY %1(s32)
----------------
The input explicitly says anyext s1 to s32, it doesn't looks like it's legalizer's problem to fix this.
