How about this:
define i32 @lo(i32) {
ret i32 0
}
define i32 @hi(i32 %n) {
ret i32 %n
}
declare i8* @wonder_allocator(i32)
define i8* @foo(i32 %n) {
%r = call i8* @wonder_allocator(i32 %n), !alloc !0
ret i8* %r
}
!0 = metadata !{ i32 (i32)* @lo, i32 (i32)* @hi }
The main problem I see is that if you declare @lo and @hi to have internal
linkage then the optimizers will zap them. Maybe there's a neat...
