As of this writing, the AIX linker can do this, as can the GNU linker for PowerPC/64. It is planned to add this feature to the GNU linker for 32-bit PowerPC systems as well. +On Mach-O (Darwin) systems, this option directs the compiler emit to +the glue for every direct call, and the Darwin linker decides whether +to use or discard it. + In the future, we may cause GCC to ignore all longcall specifications when the linker is known to generate glue. -- cgit v1.1
