[v12.x]: deps: V8: Add Power9/10 to the supported list and enable related features
Please note that enum values are slightly different from V8 upstream, i.e PPC_POWER10
instead of kPPCPower10
.
Power 9 is also added to some of the features within the ppc assembler, this is to make adding P10 consistent and is not part of the original CL on V8.
We have SIMD enabled upstream which will not be backported here.
