I must respectfully beg your pardon and request clarification. I am
contemplating adding bignum capabilities to an existing MacOS
application (an R5 Scheme implementation, Wraith Scheme, which I wrote
and maintain). It looks like it will require considerable time and
effort sufficiently to master GMP to implement Scheme bignums using
it, and because of the previous discussion concerning register x18, I
have thus far avoided taking the plunge. Therefore I asked a yes/no
question about whether it was reasonable for me to proceed. I suspect
that Torbjörn's answer makes perfect sense to people already at least
somewhat familiar with GMP, which -- alas -- I am not: Would someone
please provide an answer simple enough for me to decide whether now is
the time for me to join their ranks?
You can trust our release notes, which you quote from in your initial
* Support for 64-bit Arm under Macos.
(That of course does not preclude the existence of GMP bugs which affect
the platform in question, but we have surely addressed the register
usage to adhere to the relevant ABI.)
