commit 46a4882b3c7d9ec981568b8b13a3c9c39c8f8e61
Author: Pedro Alves <palves@redhat.com>
Date:   Mon Sep 4 20:21:15 2017 +0100

    Stop assuming no-debug-info variables have type int

We now have to explicitly tell GDB the type of the non-debug-info
variable we want to print (by casting).  This commit adjusts the
"print" statement on gdb.arch/i386-sse-stack-align.exp to do the
proper cast, fixing a failure that started to happen after the
mentioned commit.

	* gdb.arch/i386-sse-stack-align.exp: Cast "print" variable to
	"int".

This is OK, except...

... this is printing/calling a function, not a variable:

 (gdb) print g0 ()
 'g0' has unknown return type; cast the call to its declared return type

So the git log and ChangeLog are inaccurate and should
reference 7022349d5c86 ("Stop assuming no-debug-info functions
return int") instead.

OK with that fixed.

Thanks,
Pedro Alves

Thanks for the catch, I adjusted the ChangeLog entry and the commit
message accordingly.
