Sorry, can't help with you objconv, COFF, ELF, etc.

A little something about terminology though: "CTFE" in the
narrower sense refers to those occurrences of compile time
evaluation that are specified to happen. Static initializers are
CTFE-ed, for example. CTFE is not an optimization that a compiler
may or may not do.

The term for the optimization would be "constant folding", I
think. Your question, as I understand it, is about constant
folding, not about CTFE.
