I'd like to check if a function got CTFE, ie, the compiler was

I'm trying to convert the binary executable to assembly by
using objconv tool but I'm finding it very diffucult to find
anything in there, since some converters I've used which does
ELF to ASM keep the function name, e.g, foo() function is a foo
label somewhere in the file but this convert doesn't and use
some numbers instead of. I don't know if it's related how is
the windows object file format designed.
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.
