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.
bcds.: Decimal signed shift
bcdus.: Decimal unsigned shift
bcdsr.: Decimal shift and round
bcdtrunc.: Decimal signed trucate
bcdutrunc.: Decimal unsigned truncate
