Indeed.

  There has been previous discussion of possible problems using GMP in
  macOS because Apple reserves register x18 for undisclosed purposes,
  whereas GMPs mpn/arm64 assembly code uses that register.

sed 's/uses/used/'

  Does GMP release  6.3.0 still use x18 in mpn/arm64 assembly code under macOS?

If you know where to look (mpn/arm64) then isn't it quite plain to
answer your question?
