Subject: [PATCH,V1 04/14] gas: testsuite: add new tests for SFrame unwind info
Date: Thu, 29 Sep 2022 17:04:30 -0700 [thread overview]
Message-ID: <20220930000440.1672106-5-indu.bhagat@oracle.com> (raw)
In-Reply-To: <20220930000440.1672106-1-indu.bhagat@oracle.com>
Earlier these tests were in the same commit as previous which adds the
support in GNU assembler to generate .sframe section from CFI
directives. Splitting this out here for ease of applying and testing.
ChangeLog:
