Subject: [PATCH, V2 01/10] gas: dw2gencfi: minor rejig for cfi_sections_set and all_cfi_sections
Date: Mon, 30 Oct 2023 09:51:28 -0700 [thread overview]
Message-ID: <20231030165137.2570939-2-indu.bhagat@oracle.com> (raw)
In-Reply-To: <20231030165137.2570939-1-indu.bhagat@oracle.com>
[No changes from the RFC patch set]
- cfi_sections_set is best set to true in cfi_dot_startproc (). Setting
it to true again in other APIs (dot_cfi_endproc, dot_cfi_fde_data, and
cfi_finish) is unnecessary.
- move setting the global var all_cfi_sections into cfi_set_sections ().
gas/
* dw2gencfi.c (cfi_set_sections): Set cfi_sections_set and
cfi_sections here.
(dot_cfi_startproc): Remove unnecessarily setting
cfi_set_sections to true.
(dot_cfi_endproc): Likewise.
(dot_cfi_fde_data): Likewise.
(cfi_finish): Likewise.
