+ across object boundaries. From the ABI:
+
+ In this ABI, the address of a function is actually the address of a
+ function descriptor. A reference to a function, other than a function
+ call, will normally load the address of the function descriptor from
+ the global offset table. The dynamic linker will ensure that for a
+ given function, the same address is used for all references to the
+ function from any global offset table. Thus, function address
+ comparisons will work as expected.
+
+ When making a call to the function, the code may refer to the
+ procedure linkage table entry, in order to permit lazy symbol
+ resolution at run time. In order to support correct function address
+ comparisons, the compiler should be careful to only generate
+ references to the procedure linkage table entry for function calls.
+ For any other use of a function, the compiler should use the real
+ address.
+
+ I don't see how this could ever work when passing a pointer to
+ a function across an object boundary. The compiler has no
+ way of knowing how to find the function descriptor for a
+ function whose entrypoint is taken as an argument.
+
+ Or should the compiler arrange so that the function descriptor
+ address is passed and make the callee dig out the entry point
