Hi,
gcc-6.2.1-1.fc26.x86_64
# Set a breakpoint with multiple probe locations.
gdb_test "break -pstap test:two" \
"Breakpoint \[0-9\]+ at $hex.*2 locations.*" \
"set multi-location probe breakpoint (probe two)"
break -pstap test:two^M
Breakpoint 2 at 0x4004e0^M
(gdb) FAIL: gdb.base/stap-probe.exp: without semaphore, optimized: set multi-location probe breakpoint (probe two)
# Set a breakpoint with multiple probe locations.
# In this scenario, we may expect more than 2 locations because of
# the optimizations (inlining, loop unrolling, etc).
gdb_test "break -pstap test:two" \
"Breakpoint .* at $hex.*\[0-9\]+ locations.*" \
"set multi-location probe breakpoint (probe two)"
break -pstap test:two^M
Breakpoint 2 at 0x4004e0^M
(gdb) FAIL: gdb.base/stap-probe.exp: with semaphore, optimized: set multi-location probe breakpoint (probe two)
OK for check-in?
