Subject: [PULL 7/9] linux-user: Check for ieee128 fpbits in PPC64 HWCAP2 feature list
Date: Mon, 21 Jun 2021 13:04:43 +0200 [thread overview]
Message-ID: <20210621110445.231771-8-laurent@vivier.eu> (raw)
In-Reply-To: <20210621110445.231771-1-laurent@vivier.eu>
From: Khem Raj <raj.khem@gmail.com>
glibc 2.34 is now checking for this in hwcaps at
runtime [1] and failing to run the binary if machine
does not support 128bit IEEE fp
Fixes
Fatal glibc error: CPU lacks float128 support (POWER 9 or later required)
