Subject: [COMMITTED 01/15] gas: dw2gencfi: minor rejig for cfi_sections_set and all_cfi_sections
Date: Mon, 15 Jan 2024 04:07:15 -0800 [thread overview]
Message-ID: <20240115120729.29771-2-indu.bhagat@oracle.com> (raw)
In-Reply-To: <20240115120729.29771-1-indu.bhagat@oracle.com>
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. Also, 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.
