[Qemu-devel] [PATCH v3 00/10] POWER9 TCG enablements - part15 |

This series contains implentation of CA32 and OV32 bits added to the
ISA 3.0. Various fixed-point arithmetic instructions are updated to take
care of the newer flags.
Finally the last patch adds new instruction mcrxrx, that helps reading
the carry (CA and CA32) and the overflow (OV and OV32) flags
Changelog:
v2:
* Add missing condition in narrow mode(add/subf), multiply and divide
* Drop nego patch, subf implementation is sufficient for setting OV and OV32
* Retaining neg[.], as the code is simplified.
* Fix OV resetting in compute_ov()
v1:
* Use these ISA 3.0 flag to enable CA32 and OV32
* Re-write ca32 compute routine
* Add setting of flags for "neg." and "nego."
Nikunj A Dadhania (10):
target/ppc: move cpu_[read, write]_xer to cpu.c
target/ppc: optimize gen_write_xer()
target/ppc: support for 32-bit carry and overflow
target/ppc: update ca32 in arithmetic add

target/ppc: update overflow flags for add/sub
target/ppc: use tcg ops for neg instruction
target/ppc: add ov32 flag for multiply low insns
target/ppc: add ov32 flag in divide operations
target/ppc: add mcrxrx instruction
