<pre>This program should fail the verifier, as the blockaddress pointer type does
not match the function's address space.
target datalayout = "e-p:64:64-p1:32:32-P1"
define i32 @label_size(i64 %idx) addrspace(1) {
entry:
%int = ptrtoint i8* blockaddress(@label_size, %bb) to i32
br label %bb
bb:
ret i32 %int
}
If you do use the correct pointer type, the parser fails on it:
define i32 @label_size(i64 %idx) addrspace(1) {
entry:
%int = ptrtoint i8 addrspace(1)* blockaddress(@label_size, %bb) to i32
br label %bb
bb:
ret i32 %int
}
gives "error: constant expression type mismatch"
Additionally, DataLayout::getTypeSizeInBits does not account for the program
address space when checking for the size of labels.</pre>
