22/* libpthread used to have its own vfork implementation that differed
23 from libc's only in having a pointless micro-optimization. There
24 is no longer any use to having a separate copy in libpthread, but
25 the historical ABI requires it. For static linking, there is no
26 need to provide anything here--the libc version will be linked in.
27 For shared library ABI compatibility, there must be __vfork and
28 vfork symbols in libpthread.so.
29
30 As of GCC 7, microblaze can *not* rely on the compiler to generate
31 a tail call from this vfork to __libc_vfork. */
