Hi,

Tests in gdb.arch/thumb2-it.exp call functions defined in assembly
without type debugging information. Since
7022349d5c86bae74b49225515f42d2e221bd368 this triggers an error which
leads to many tests to FAIL. This patch cast the call to indicate the
return type of the functions when calling them.

ChangeLog entry is as follows:

*** gdb/testsuite/ChangeLog ***

2017-09-06  Thomas Preud'homme  <thomas.preudhomme@arm.com>

	* gdb.arch/thumb2-it.exp: Cast call to assembly defined function.

All tests in that exp file PASS after that change.

Is this ok for master?

Best regards,

Thomas
