Subject: [PATCH v2 kvm-unit-tests 0/2] fix long division routines for ARM eabi
Date: Wed, 12 May 2021 12:54:38 +0200 [thread overview]
Message-ID: <20210512105440.748153-1-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.
Paolo
v1->v2: fix __divmoddi4, make sure -DTEST covers it
Paolo Bonzini (2):
libcflat: clean up and complete long division routines
arm: add eabi version of 64-bit division functions
