We now do a single pass over the HIR, building up two data structures:
* One tracks values that are known macro tags or macro calls.
* One tracks operands of macro-related instructions so that we can later group them.
After building up these data structures, we do a pass over the latter structure. For each macro call instruction, we recursively traverse its operands to ensure they're in the same scope. Thus, something like `fbt('hello' + fbt.param(foo(), "..."))` will correctly merge the fbt call, the `+` binary expression, the `fbt.param()` call, and `foo()` into a single scope.
React Compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
More information about the design and architecture of the compiler are covered in the Design Goals.
More information about developing the compiler itself is covered in the Development Guide.
