Subject: [PATCH 7/9] target/microblaze: Use TARGET_LONG_BITS == 32 for system mode
Date: Wed, 12 Feb 2025 14:01:53 -0800	[thread overview]
Message-ID: <20250212220155.1147144-8-richard.henderson@linaro.org> (raw)
In-Reply-To: <20250212220155.1147144-1-richard.henderson@linaro.org>

Now that the extended address instructions are handled separately
from virtual addresses, we can narrow the emulation to 32-bit.
