Subject: [PATCH v3 10/10] disas: Remove target_words_bigendian() call in initialize_debug_target()
Date: Mon, 10 Feb 2025 23:18:30 +0100	[thread overview]
Message-ID: <20250210221830.69129-11-philmd@linaro.org> (raw)
In-Reply-To: <20250210221830.69129-1-philmd@linaro.org>

All CPUClass implementating disas_set_info() must set the
disassemble_info::endian value.

Ensure that by setting %endian to BFD_ENDIAN_UNKNOWN before
calling the CPUClass::disas_set_info() handler, then asserting
%endian is not BFD_ENDIAN_UNKNOWN after the call.

This allows removing the target_words_bigendian() call in disas/.
