There seems to be more then just a missing level of dereferencing going on. For example, I think that the program, when compiled with -fprofile-generate, should be putting an address into __gcov_indirect_call_callee before calling __gcov_indirect_call_profiler (if I am reading the x86 code correctly) but on IA64 I don't see anything that writes to __gcov_indirect_call_callee. There is already a defect for this bug, PR 32277, I may just add what I have found to the PR and XFAIL the test like Richard suggested. It has never worked on IA64. Steve Ellcey [EMAIL PROTECTED]
