Bug ID: 18003
Summary: Some fails in gdb.base/breakpoint-in-ro-region.exp
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: qiyao at gcc dot gnu.org

I see some fails as below on aarch64-linux-gnu target, in both remote and
native testing...

si^M
0x0000000000400738 23 i = 0;^M
(gdb) FAIL: gdb.base/breakpoint-in-ro-region.exp: always-inserted off: auto-hw
off: step in ro region

si^M
0x0000000000400740 24 i = 0;^M
(gdb) FAIL: gdb.base/breakpoint-in-ro-region.exp: always-inserted on: auto-hw
off: step in ro region

looks the hex is unexpected to the pattern matching,

set test "step in ro region"
gdb_test_multiple "si" $test {
-re "Could not insert hardware breakpoints.*$gdb_prompt $" {
gdb_assert {!$hw_step && $auto_hw == "on" && !$supports_hbreak} \
"$test (cannot insert hw break)"
}
-re "Cannot set software breakpoint at read-only address
$next_insn.*$gdb_prompt $" {
gdb_assert {!$hw_step && $auto_hw == "off"} \
"$test (cannot insert sw break)"
}
-re "^si\r\nNote: automatically using hardware breakpoints for read-only
addresses\.\r\n${decimal}\[ \t\]+i = 0;\r\n$gdb_prompt $" {
gdb_assert {!$hw_step && $auto_hw == "on" && $supports_hbreak} \
"$test (auto-hw)"
}
-re "^si\r\n${decimal}\[ \t\]+i = 0;\r\n$gdb_prompt $" {
gdb_assert {$hw_step || ($auto_hw == "on" && $supports_hbreak)} \
"$test (no error)"
}
}

further analysis is needed.

The test case is now passing with the upstream gdb:
