v6: - improves bcdtrunc/bcdutrunc overflow comparison - removes bcds/bcdus/bcdsr applied patches
v5: - removes 'unlikely' gcc branch pred. hints from not unlikely places - adds comments in host-utils functions - adds more test cases for shift functions - handles "shift backwards" with signed shifts - rebases branch v4: - improves functions to behave exactly like the target v3: - moves shift functions to host-utils.c and added config_int128 guard - changes Makefile to always compile host-utils.c - redesigns bcd[u]trunc to use bitwise operations - removes "target-ppc: Implement bcd_is_valid function" (merged) v2: - bcd[s,sr,us] uses 1 byte for shifting instead of 4 bytes - left/right functions in host-utils are out of CONFIG_INT128 - fixes overflowing issue in left shift and added a testcase This serie contains 5 new instructions for POWER9 ISA3.0, left/right shifts for unsigned quadwords and a small improvement to check whether a bcd value is valid or not. bcdtrunc.: Decimal signed trucate bcdutrunc.: Decimal unsigned truncate Jose Ricardo Ziviani (2): ppc: Implement bcdtrunc. instruction ppc: Implement bcdutrunc. instruction target/ppc/helper.h | 2 + target/ppc/int_helper.c | 88 +++++++++++++++++++++++++++++++++++++ target/ppc/translate/vmx-impl.inc.c | 9 ++++ target/ppc/translate/vmx-ops.inc.c | 6 +-- 4 files changed, 102 insertions(+), 3 deletions(-) -- 2.7.4
