Thank you very much for information!
Could you point me where I can find source code of that mingw runtime
pseudo relocations fixer? It is in mingw-w64 or in libgcc code base?
It's here:
https://github.com/mingw-w64/mingw-w64/blob/master/mingw-w64-crt/crt/pseudo-reloc.c
And how smart is LTO optimization for these cases? Could be usage of
regularGlobal and regularFunction postponed to LTO phase and converted
to __imp_?
Hmm, interesting idea. In theory I guess it should be possible to figure
out such details, by having access to all the symbols involved before
actually doing the LTO compilation, and then feeding that info into the
LTO compilation. But in practice I think it's hard to achieve this due to
the layering between linker and LTO compiler.
