Subject: [PATCH for-9.2 v2 0/4] target/m68k: Implement fmove.p
Date: Mon, 12 Aug 2024 10:44:47 +1000 [thread overview]
Message-ID: <20240812004451.13711-1-richard.henderson@linaro.org> (raw)
Implement packed decimal real conversions.
Changes for v2:
* Generate the complete set of powers of 10 for floatx80.
This was enough to get 9.9999999999999999e999 properly rounded.
