dnl Usage: CALL(funcname)
dnl
dnl Simply override the definition in x86_64-defs.m4.

dnl CAUTION: Do not put anything sensible here, like RODATA. That works with
dnl some Darwin tool chains, but silently breaks with other. (Note that
dnl putting jump tables in the text segment is a really poor idea for many PC
dnl processors, since they cannot cache the same thing in both L1D and L2I.)

dnl Target ABI macros. For Darwin we override IFELF (and leave default for

dnl Usage: PROTECT(symbol)
dnl
dnl Used for private GMP symbols that should never be overridden by users.
