Follow-ups

--- Vivi Li 2009-11-08 21:58:38

It still fails.

--- Vivi Li 2009-11-10 01:43:30

SHARED-FLAT format now works.

FDPIC format still fails.

--- Bernd Schmidt 2009-11-13 06:36:39

That's because the xip_test program doesn't test the right thing on FD-PIC.

Function pointers in FD-PIC are pointers to function descriptors, which are

data, not code, and therefore not shared by XIP.

--- Vivi Li 2009-11-17 02:49:51

Fix xip_test program to test right address on FD-PIC.

--- Vivi Li 2009-11-19 03:52:11

OK now. Close this bug.
