When running test-case gdb.ada/formatted_ref.exp with gcc-11 and target board unix/gdb:debug_flags=-gdwarf-4 we run into: ... (gdb) print/x s^M No definition of "s" in current context.^M (gdb) FAIL: gdb.ada/formatted_ref.exp: print/x s ... which is caused by "runto defs.adb:20" taking us to defs__struct1IP: ... (gdb) break defs.adb:20^M Breakpoint 1 at 0x402cfd: defs.adb:20. (2 locations)^M (gdb) run ^M Starting program: formatted_ref ^M ^M Breakpoint 1, defs__struct1IP () at defs.adb:20^M 20 return s.x; -- Set breakpoint marker here.^M (gdb) print s1'access^M ... instead of the expected defs.f1: ... (gdb) break defs.adb:20^M Breakpoint 1 at 0x402d0e: file defs.adb, line 20.^M (gdb) run ^M Starting program: formatted_ref ^M ^M Breakpoint 1, defs.f1 (s=...) at defs.adb:20^M 20 return s.x; -- Set breakpoint marker here.^M ... This is caused by incorrect line info due to gcc PR 101575 - "[gcc-11, -gdwarf-4] Missing .file <n> directive causes invalid line info". Fix this by when landing in defs__struct1IP: - xfailing the runto, and - issuing a continue to land in defs.f1. Likewise in a few other test-cases. Tested on x86_64-linux, with: - system gcc. - gcc-11 and target boards unix/gdb:debug_flags=-gdwarf-4 and unix/gdb:debug_flags=-gdwarf-5. gdb/testsuite/ChangeLog: 2021-07-22 Tom de Vries <tdevries@suse.de> * gdb.ada/formatted_ref.exp: Add xfail for PR gcc/101575. * gdb.ada/iwide.exp: Same. * gdb.ada/pkd_arr_elem.exp: Same.

# Note: This test is essentially a transcription of gdb.cp/formatted-ref.exp,
|
|
# and is thus much more wordy than it needs to be. There are fewer
|
|
# tests because only a few parameter types in Ada are required to be
|
|
# passed by reference, and there is no equivalent of &(&x) for reference
|
|
# values.
|
|
# This also tests that some other arithmetic operations on references
|
|
# work properly: condition expression using a reference object as one of its
|
|
# operand.
