Subject: [PATCH v11 1/3] MIPS: Add ELF file header flags
Date: Wed, 30 Aug 2023 23:22:46 -0400	[thread overview]
Message-ID: <20230831032302.3736352-2-ying.huang@oss.cipunited.com> (raw)
In-Reply-To: <20230831032302.3736352-1-ying.huang@oss.cipunited.com>

From: Ying Huang <ying.huang@oss.cipunited.com>

Now binutils use some E_MIPS_* macros and EF_MIPS_* macros, it is
difficult to decide which style macro we should use when we want
to add new ELF file header flags.
IRIX used to use EF_MIPS_* macros and in elf/elf.h there also has
comments "The following are unofficial names and should not be used".
So we should use EF_MIPS_* to keep same style with the beginning.
