Subject: perf test: Skip test_arm_callgraph_fp.sh if unwinding isn't built in
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ac668d529fca730f318db3bfa7141743bf75976d;p=linux.git

perf test: Skip test_arm_callgraph_fp.sh if unwinding isn't built in

Even though this is a frame pointer unwind test, it's testing that a
frame pointer stack can be augmented correctly with a partial
Dwarf unwind. So add a feature check so that this test skips instead of
fails if Dwarf unwinding isn't present.
