Originally we've used `!__MINGW64__` but changed it to `__ELF__` upon feedback received. Should I change it back to `!__MINGW64__`? Or introduce '__COFF__' and then use `!__COFF__`? What would be the minimal acceptable change? we are currently probably not able to provide that generic solution as has Iain Sandoe implied. Note that we have moved the pseudo-ops wrapper macros to the `libgcc/config/aarch64/aarch64-asm.h` file already.
Thank you all for your valuable feedback. Radek
