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.
bcds.: Decimal signed shift
bcdus.: Decimal unsigned shift
bcdsr.: Decimal shift and round
bcdtrunc.: Decimal signed trucate
bcdtrunc.: Decimal unsigned truncate
Jose Ricardo Ziviani (7):
target-ppc: Implement bcd_is_valid function
target-ppc: Implement unsigned quadword left/right shift and unit
tests
target-ppc: Implement bcds. instruction
target-ppc: Implement bcdus. instruction
target-ppc: Implement bcdsr. instruction
target-ppc: Implement bcdtrunc. instruction
target-ppc: Implement bcdtrunc. instruction
