Thanks. That could be done. Can you help me understand whether such changes
will still enable us to do the following:
1. Make calls like `achar(...)`, which would be required when we upstream
support for `-finit-character`
2. Make calls like `x = ieee_value(x, ieee_quiet_nan)`, which would be required
when we support `-finit-real` (would fix
https://github.com/llvm/llvm-project/issues/159794). We also need similar
`ieee_value` calls for `inf/nan/snan/-inf`.
The reason I thought to handle assignments through `parser::` is that I could
not understand how we could directly emit such assignments as I exemplified
here through HLFIR. Although I understand such calls are not needed for this
PR, I intend to share functionality for all `-finit-*` flags. If there is a way
where we can handle these cases in HLFIR, I would be happy to rework this PR.
