Subject: [PATCH] sections.h: dereference_function_descriptor() returns void pointer
Date: Tue, 11 Aug 2020 12:30:50 +0200 [thread overview]
Message-ID: <20200811103050.GA6645@ls3530.fritz.box> (raw)
The function dereference_function_descriptor() takes on hppa64, ppc64
and ia64 a pointer to a function descriptor and returns a (void) pointer
to the dereferenced function.
To make cross-arch coding easier, on all other architectures the
dereference_function_descriptor() macro should return a void pointer
too.
