Subject: [PATCH 10/10] [gdb/testsuite] Add gdb.arch/s390-disassemble.exp
|
|
|
|
In commit a98a6fa2d8e ("s390: Add arch15 instructions"), support for
|
|
new instructions was added to libopcodes, but the added tests only exercise
|
|
this for gas.
|
|
|
|
Add a test-case gdb.arch/s390-disassemble.exp that checks gdb's ability to
|
|
disassemble one of these instructions.
|
|
|
|
Tested on s390x-linux.
