Subject: [PATCH 1/3] scripts/sorttable: Change section type of orc_lookup to SHT_PROGBITS
Date: Wed, 3 Jun 2020 22:39:43 +0800 [thread overview]
Message-ID: <20200603143945.64248-2-changhuaixin@linux.alibaba.com> (raw)
In-Reply-To: <20200603143945.64248-1-changhuaixin@linux.alibaba.com>
In order to edit orc_lookup table via sorttable, type of section
orc_lookup needs to be SHT_PROGBITS instead of SHT_NOBITS.
Linker script doesn't seem to allow manual specification of the section
type, so just write a byte into the section instead.
