Subject: [PATCH kvm-unit-tests 0/2] fix long division routines for ARM eabi
Date: Tue, 11 May 2021 19:41:04 +0200	[thread overview]
Message-ID: <20210511174106.703235-1-pbonzini@redhat.com> (raw)

As reported by Alexandru, ARM follows a different convention than
x86 so it needs __aeabi_ldivmod and __aeabi_uldivmod.  Because
it does not use __divdi3 and __moddi3, it also needs __divmoddi4
to build the eabi function upon.
