Subject: [PATCH v2 15/31] perf disasm: Add e_machine/e_flags to struct arch
Date: Sat,  5 Oct 2024 12:55:25 -0700	[thread overview]
Message-ID: <20241005195541.380070-16-irogers@google.com> (raw)
In-Reply-To: <20241005195541.380070-1-irogers@google.com>

Currently functions like get_dwarf_regnum only work with the host
architecture. Carry the elf machine and flags in struct arch so that
in disassembly these can be used to allow cross platform disassembly.
