Re: [v8-users] 32-bit powerpc -- a lost cause?

[michael_dawson]

Based on current priorities, going forward 32 bit is not going to be a 
priority.  We will not be testing it in v8 or the Node.js repos.

Hi,

although NetBSD runs on various PPC hardware, some possibly also with no 
FPU,
my personal interest is in >= G4 (possibly >= G3), which AFAIK means 32-bit 
but with FPU.
However, reading what you write I get the sense that you're going to drop 
all 32-bit PPC support?

Regards,

- Håvard

Hi,

We currently do not support PPC 32bit hardware and going forward with Node8 
will be dropping support for PPC 32bit mode builds on PPC 64bit 
architecture. Also, it is possible the 32 bit PPC system you are using is 
only implementing a subset of the architecture and missing FPU.

Regards,
Jaideep

Ah.  I'm new in these quarters.  Thanks for the pointer, I may do just that.

Hey Håvard,

The ppc port is not maintained by the V8 team itself, but by IBM (see
src/ppc/OWNERS). I don't know about the state and scope of the port. Maybe
you want to reach out to the port owners.
