As I said before, we chose not to work around every Xcode quirk, since
there are too many, and the result would be that GMP would become harder
to maintain. The workaround is instead to use a different Xcode.
(You should remember that Apple machines is just one of many dozens of
platforms we support. Imagine the mess we would create if we tried to
handle every odd behaviour in each toolchain of each platform!)
It sounds like if you kept everything in C and accepted the default PIC,
many problems would go away?
What does "default PIC" mean?
I believe our asm PIC code now is accepted by any Xcode from the last 5
"Keeping everything in C", the use of "none" above, is what the gcc build
does when it builds gmp.
Very wise of them. They don't need the speed of the assembly code.
