[COMMITTED,V2,4/5,4/5] gas: sframe: testsuite: add testcase for .cfi_b_key_frame
Checks
Commit Message
[Changes in V2]
- Adjust the testcase as we now emit "[s]" marker when the return
address in either reg / stack is mangled.
[End of changes in V2]
This is actually a composite test that checks the behaviour of both the
.cfi_negate_ra_state and .cfi_b_key_frame directives on aarch64.
ChangeLog:
* testsuite/gas/cfi-sframe/cfi-sframe-aarch64-pac-ab-key-1.d:
New test.
* testsuite/gas/cfi-sframe/cfi-sframe-aarch64-pac-ab-key-1.s:
Likewise.
* testsuite/gas/cfi-sframe/cfi-sframe.exp: Run new test.
