Subject: [Qemu-devel] [PATCH v3 0/4] POWER9 TCG enablements - BCD functions part II
Date: Fri, 25 Nov 2016 01:53:29 -0200	[thread overview]
Message-ID: <1480046013-24788-1-git-send-email-joserz@linux.vnet.ibm.com> (raw)

v3:
 - use decimal numbers instead of hex when appropriate
 - set condition register flag to the new form
 - fix bcdcfsq loops boundaries

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
