Re: OSX i386/x86 and x86_64 - time to switch supported platforms?

To make it clear. Leopard (released October 2007) fully supports x86_64 executables. Given upgrade rate of Mac community I think it's pretty safe to state that majority of mac owners have x86-64 capable systems. pavel On 01.02.2011, at 15:30, malcolm.wallace wrote:

MacOS 10.5 is still largely 32-bit. MacOS 10.6 is largely 64-bit. Both are capable of compiling and running for the alternative word-size choice, fairly transparently. 10.6 was released August 2009, but there are likely plenty of people still running 10.5. Regards, Malcolm

Even though the hardware is x86_64, I thought the vast majority of macs used a 32 bit build of OSX and 32 bit programs?

The last 32-bit, Intel Mac was the Mac Mini, discontinued in August 2007. The bulk of them were discontinued in 2006, along with PowerPC Macs. Does it make sense to relegate OSX x86_64 to community status while the 32-bit version is considered a supported platform?

Given that I'm far from experienced enough to be able to contribute meaningfully to GHC, I'm not complaining about anyone's efforts, just that those efforts might be a bit misallocated. I'd venture a guess that far more people are interested in running 64-bit GHC on OSX than in running GHC on what is now fairly antiquated hardware.
