The following TZIR instrutions have been implemented in the backend:
- all cmp operators (lt, lte, gt, gte, eq, neq)
- block
- br
- condbr
The following LLVMIR is generated for a simple assert function:
```
define void @assert(i1 %0) {
Entry:
%1 = alloca i1, align 1
store i1 %0, i1* %1, align 1
%2 = load i1, i1* %1, align 1
%3 = xor i1 %2, true
br i1 %3, label %Then, label %Else
Then: ; preds = %Entry
call void @llvm.debugtrap()
unreachable
Else: ; preds = %Entry
br label %Block
Block: ; preds = %Else
ret void
}
```
See tests for more examples.
