Subject: [Qemu-devel] [PATCH v2 0/4] POWER9 TCG enablements - BCD functions part II
Date: Wed, 23 Nov 2016 14:21:41 -0200 [thread overview]
Message-ID: <1479918105-15616-1-git-send-email-joserz@linux.vnet.ibm.com> (raw)
v2:
- use div128 and mul64 functions to make code easier to understand
- fixed int128 neg
- improved functions bcdcpsgn and bcdsetsgn to do less work
than necessary
- rebased on ppc-for-2.9
This serie contains 4 new instructions for POWER9 ISA3.0
bcdcfsq.: Convert signed quadword to packed BCD
bcdctsq.: Convert packed BCD to signed quadword
bcdcpsgn.: Copy the sign of a register to another
bcdsetsgn.: Set the BCD sign according to a preferred sign
Jose Ricardo Ziviani (4):
target-ppc: Implement bcdcfsq. instruction
target-ppc: Implement bcdctsq. instruction
target-ppc: Implement bcdcpsgn. instruction
target-ppc: Implement bcdsetsgn. instruction
