Subject: [PATCH] linux-user: Check for ieee128 fpbits in PPC64 HWCAP2 feature list
Date: Mon, 14 Jun 2021 12:17:29 -0700 [thread overview]
Message-ID: <20210614191729.2981488-1-raj.khem@gmail.com> (raw)
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)
