To play with ai assistance and new systemtap try bot feature here's a task:

Bug PR15052 is Fixed! Multiple Tests Still Expect Failure

 Tests Affected:
 - systemtap.base/sdt_global_var.exp
 - systemtap.base/at_var_mark.exp
 - systemtap.base/at_var_mark_func.exp

 Status: KPASS (known failure but now passes)
 Bug: PR15052 - dyninst runtime with PIE (Position Independent Executable)
support was broken

 What's Happening

 Multiple tests have this code to mark dyninst + PIE as an expected failure:

 In sdt_global_var.exp:23:
 if {$runtime == "dyninst" && [regexp "\-pie" $TEST_NAME]} {
     setup_kfail 15052 "*-*-*"
 }  

 In at_var_mark.exp:17 and at_var_mark_func.exp:17:
 setup_kfail 15052 "*-*-*"

 But these tests now pass! The bunsen results show multiple KPASS:
 - sdt_global_var uprobe additional_flags=-fPIE additional_flags=-pie
additional_flags=-O2 (dyninst) (PRMS 15052) - KPASS
 - at_var_mark (dyninst) startup (PRMS 15052) - KPASS
 - at_var_mark_func (dyninst) startup (PRMS 15052) - KPASS

 The Easy Fix

 File 1: testsuite/systemtap.base/sdt_global_var.exp
 Remove lines 22-24:
 if {$runtime == "dyninst" && [regexp "\-pie" $TEST_NAME]} {
     setup_kfail 15052 "*-*-*"
 }  

 File 2: testsuite/systemtap.base/at_var_mark.exp
 Remove line 17:
 setup_kfail 15052 "*-*-*"

 File 3: testsuite/systemtap.base/at_var_mark_func.exp
 Remove line 17:
 setup_kfail 15052 "*-*-*"

 The dyninst runtime now correctly handles PIE binaries, so we should let these
tests pass normally!
