dropping 32bit support would be very short-sighted. reasons: 1. arm support (build on arm NOT x86, x86 qemu). 2. x32 (32bit pointers but with 64bit mode ops last i checked). if the problem is qemu on 32bit x86 emulating arm... mayhaps we should talk about that issue itself? i remember there being memory mapping conflicts/issues in doing misc binary emul, but i don't remember the details anymore. > Hi, Auke > > The major reason of 32bit-linux-platform tools support dropping plan is the > qemu issue: we still have no stable 32bit qemu-static executable for current > Tizen, which is very important for the local build and image creation in 32bit > development systems. > > And the future 64bit support of Tizen itself is only the last straw of it. > Whenever the 64bit Tizen development is the necessary part of developers' > work, they can only use 64bit development environment. > > thanks > - jf.ding > > On Wed, Sep 18, 2013 at 12:47:54PM -0700, Kok, Auke-jan H wrote: > > On Wed, Sep 18, 2013 at 12:21 PM, Tomasz Olszak <[email protected]> > > wrote: > > > > > > I'm opposed to this. > > >> > > >> > > >> 64bit support in Tizen is not yet mainstream at all, as a matter of > > >> fact it's barely been implemented in 3.0, and no major release that > > >> developers can use yet has happened. > > >> > > >> Can we maintain 32bit code until most developers have had a major > > >> release on 64bit?
