Link-time optimization for the kernelLink-time optimization for the kernelPosted Aug 23, 2012 8:07 UTC (Thu) by gb (subscriber, #58328)In reply to: Link-time optimization for the kernel by andikleen Parent article: Link-time optimization for the kernel
Interesting experiment, but what's the point of building 32-bit kernels at this moment then 64-bit installations are more common than 32-bit?

Is that really true in the mobile space? ;-)

In the mobile space we have arm and it has plenty of registers doesn't it?

It does and AArch64 is not far away, given rate of change within the mobile/pad fad-driven world the new chips will start hitting market sooner rather than later.

I was thinking more of 32-bits Atom.
ARM Thumb wouldn't have many registers either, but I don't know whether you could (or could want to) build an ARM Thumb linux kernel.

You can build a Thumb-2 kernel with CONFIG_THUMB2_KERNEL=y
