RE: [PATCH] [gdb/testsuite] Add xfail in gdb.python/py-record-btrace.exp

["Metzger, Markus T" <markus.t.metzger@intel.com>]

Hello Tom,

+    set have_xfail 0
+    set v [linux_kernel_version]
+    if { $v == {} } {
+	set have_xfail 0

It is already initialized to 0 so we may turn this into

    If { $v != {} } {

+    } else {
+	set have_xfail \
+	    [expr [version_compare [list 5 5 0] <= $v] \
+		 && [version_compare $v < [list 6 1 0]]]
+    }


+    set xfail_re \
+	[join \
+	     [list \
+		  "warning: Decode error \\(.*\\) at instruction $decimal" \
+		  "\\(offset = $hex, pc = $hex\\):" \
+		  "compressed return without call\\."]]

The exact error symptom may vary.  On my system I got 'bad packet context'.
It should suffice to grep for the first part, without the actual error string.

Looks good to me.

Regards,
Markus.
